Saw the new guideline came out, and used in google photos latest app.
Have no idea how to use the new Bottom Navigation Bar.
See through the new support lib, didn't find any lead.
Can not find any official sample.
How to use the new Bottom bar? Don't want to do any customize.
I think you might looking for this.
Here's a quick snippet to get started:
public class MainActivity extends AppCompatActivity {
private BottomBar mBottomBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Notice how you don't use the setContentView method here! Just
// pass your layout to bottom bar, it will be taken care of.
// Everything will be just like you're used to.
mBottomBar = BottomBar.bind(this, R.layout.activity_main,
savedInstanceState);
mBottomBar.setItems(
new BottomBarTab(R.drawable.ic_recents, "Recents"),
new BottomBarTab(R.drawable.ic_favorites, "Favorites"),
new BottomBarTab(R.drawable.ic_nearby, "Nearby"),
new BottomBarTab(R.drawable.ic_friends, "Friends")
);
mBottomBar.setOnItemSelectedListener(new OnTabSelectedListener() {
@Override
public void onItemSelected(final int position) {
// the user selected a new tab
}
});
}
@Override
protected void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
mBottomBar.onSaveInstanceState(outState);
}
}

EDIT New Releases.
The Bottom Navigation View has been in the material design guidelines for some time, but it hasn’t been easy for us to implement it into our apps. Some applications have built their own solutions, whilst others have relied on third-party open-source libraries to get the job done. Now the design support library is seeing the addition of this bottom navigation bar, let’s take a dive into how we can use it!
How to use ?
To begin with we need to update our dependency!
compile ‘com.android.support:design:25.0.0’
Design xml.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Content Container -->
<android.support.design.widget.BottomNavigationView
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:itemBackground="@color/colorPrimary"
app:itemIconTint="@color/white"
app:itemTextColor="@color/white"
app:menu="@menu/bottom_navigation_main" />
</RelativeLayout>
Create menu as per your requirement.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_favorites"
android:enabled="true"
android:icon="@drawable/ic_favorite_white_24dp"
android:title="@string/text_favorites"
app:showAsAction="ifRoom" />
<item
android:id="@+id/action_schedules"
android:enabled="true"
android:icon="@drawable/ic_access_time_white_24dp"
android:title="@string/text_schedules"
app:showAsAction="ifRoom" />
<item
android:id="@+id/action_music"
android:enabled="true"
android:icon="@drawable/ic_audiotrack_white_24dp"
android:title="@string/text_music"
app:showAsAction="ifRoom" />
</menu>
Handling Enabled / Disabled states. Make selector file.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:state_checked="true"
android:color="@color/colorPrimary" />
<item
android:state_checked="false"
android:color="@color/grey" />
</selector>
Handle click events.
BottomNavigationView bottomNavigationView = (BottomNavigationView)
findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(
new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_favorites:
break;
case R.id.action_schedules:
break;
case R.id.action_music:
break;
}
return false;
}
});
Edit : Using Androidx you just need to add below dependencies.
implementation 'com.google.android.material:material:1.2.0-alpha01'
Layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.bottomnavigation.BottomNavigationView
android:layout_gravity="bottom"
app:menu="@menu/bottom_navigation_menu"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</FrameLayout>
If you want to read more about it's methods and how it works read this.
Surely it will help you.
You should use BottomNavigationView from v25 Android Support Library. It represents a standard bottom navigation bar for application.
Here is a post on Medium that has a step by step guide: https://medium.com/@hitherejoe/exploring-the-android-design-support-library-bottom-navigation-drawer-548de699e8e0#.9vmiekxze
My original answer dealt with the BottomNavigationView, but now there is a BottomAppBar. I added a section at the top for that with an implementation link.
The BottomAppBar supports a Floating Action Button.
Image from here. See the documentation and this tutorial for help setting up the BottomAppBar.
The following full example shows how to make a Bottom Navigation View similar to the image in the question. See also Bottom Navigation in the documentation.
Add this line to your app's build.grade file next to the other support library things.
implementation 'com.android.support:design:28.0.0'
Replace the version number with whatever is current.
The only special thing we have added to the layout is the BottomNavigationView. To change the color of the icon and text when it is clicked, you can use a selector instead of specifying the color directly. This is omitted for simplicity here.
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.BottomNavigationView
android:id="@+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:menu="@menu/bottom_nav_menu"
app:itemBackground="@color/colorPrimary"
app:itemIconTint="@android:color/white"
app:itemTextColor="@android:color/white" />
</RelativeLayout>
Notice that we used layout_alignParentBottom to actually put it at the bottom.
The xml above for Bottom Navigation View referred to bottom_nav_menu. This is what defines each item in our view. We will make it now. All you have to do is add a menu resource just like you would for an Action Bar or Toolbar.
bottom_nav_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_recents"
android:enabled="true"
android:icon="@drawable/ic_action_recents"
android:title="Recents"
app:showAsAction="ifRoom" />
<item
android:id="@+id/action_favorites"
android:enabled="true"
android:icon="@drawable/ic_action_favorites"
android:title="Favorites"
app:showAsAction="ifRoom" />
<item
android:id="@+id/action_nearby"
android:enabled="true"
android:icon="@drawable/ic_action_nearby"
android:title="Nearby"
app:showAsAction="ifRoom" />
</menu>
You will need to add the appropriate icons to your project. This is not very difficult if you go to File > New > Image Asset and choose Action Bar and Tab Icons as the Icon Type.
There is nothing special happening here. We just add a listener to the Bottom Navigation Bar in our Activity's onCreate method.
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView bottomNavigationView = (BottomNavigationView) findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.action_recents:
Toast.makeText(MainActivity.this, "Recents", Toast.LENGTH_SHORT).show();
break;
case R.id.action_favorites:
Toast.makeText(MainActivity.this, "Favorites", Toast.LENGTH_SHORT).show();
break;
case R.id.action_nearby:
Toast.makeText(MainActivity.this, "Nearby", Toast.LENGTH_SHORT).show();
break;
}
return true;
}
});
}
}
I learned how to do this watching the following YouTube video. The computer voice is a little strange, but the demonstration is very clear.
You can also use Tab Layout with custom tab view to achieve this.
custom_tab.xml
<?xml version="1.0" encoding="utf-8"?>

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

MyPagerAdapter pagerAdapter = new MyPagerAdapter(getSupportFragmentManager());
viewPager.setAdapter(pagerAdapter);

mTabLayout.setupWithViewPager(viewPager);
for (int i = 0; i < mTabLayout.getTabCount(); i++) {

tab.setCustomView(pagerAdapter.getTabView(i));
}
mTabLayout.getTabAt(0).getCustomView().setSelected(true);
}

public final int PAGE_COUNT = 3;
private final String[] mTabsTitle = {"Recents", "Favorites", "Nearby"};
public MyPagerAdapter(FragmentManager fm) {
super(fm);
}
public View getTabView(int position) {
// Given you have a custom layout in `res/layout/custom_tab.xml` with a TextView and ImageView
View view = LayoutInflater.from(MainActivity.this).inflate(R.layout.custom_tab, null);
TextView title = (TextView) view.findViewById(R.id.title);
title.setText(mTabsTitle[position]);
ImageView icon = (ImageView) view.findViewById(R.id.icon);
icon.setImageResource(mTabsIcons[position]);
return view;
}
@Override
public Fragment getItem(int pos) {
switch (pos) {
case 0:
return PageFragment.newInstance(1);

return PageFragment.newInstance(2);

return PageFragment.newInstance(3);
}
return null;

@Override

Google has launched the BottomNavigationView after the version 25.0.0 of the design support library. But it came with the following limitations:
So the max you can do with this fist version of BottomNavigationView is: (without any reflection or implementing the lib by yourself).
So, If you want any of these. You can use a third part library like roughike/BottomBar or implement the lib by yourself.
As Sanf0rd mentioned, Google launched the BottomNavigationView as part of the Design Support Library version 25.0.0. The limitations he mentioned are mostly true, except that you CAN change the background color of the view and even the text color and icon tint color. It also has an animation when you add more than 4 items (sadly it cannot be enabled or disabled manually).
I wrote a detailed tutorial about it with examples and an accompanying repository, which you can read here: https://blog.autsoft.hu/now-you-can-use-the-bottom-navigation-view-in-the-design-support-library/
You have to add these in your app level build.gradle:
compile 'com.android.support:appcompat-v7:25.0.0'
compile 'com.android.support:design:25.0.0'
You can include it in your layout like this:
<android.support.design.widget.BottomNavigationView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/bottom_navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:itemBackground="@color/darkGrey"
app:itemIconTint="@color/bottom_navigation_item_background_colors"
app:itemTextColor="@color/bottom_navigation_item_background_colors"
app:menu="@menu/menu_bottom_navigation" />
You can specify the items via a menu resource like this:
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/action_one"
android:icon="@android:drawable/ic_dialog_map"
android:title="One"/>
<item
android:id="@+id/action_two"
android:icon="@android:drawable/ic_dialog_info"
android:title="Two"/>
<item
android:id="@+id/action_three"
android:icon="@android:drawable/ic_dialog_email"
android:title="Three"/>
<item
android:id="@+id/action_four"
android:icon="@android:drawable/ic_popup_reminder"
android:title="Four"/>
</menu>
And you can set the tint and text color as a color list, so the currently selected item is highlighted:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:color="@color/colorAccent"
android:state_checked="false"/>
<item
android:color="@android:color/white"
android:state_checked="true"/>
</selector>
Finally, you can handle the selection of the items with an OnNavigationItemSelectedListener:
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
Fragment fragment = null;
switch (item.getItemId()) {
case R.id.action_one:
// Switch to page one
break;
case R.id.action_two:
// Switch to page two
break;
case R.id.action_three:
// Switch to page three
break;
}
return true;
}
});
Other alternate library you can try :- https://github.com/Ashok-Varma/BottomNavigation
<com.ashokvarma.bottomnavigation.BottomNavigationBar
android:layout_gravity="bottom"
android:id="@+id/bottom_navigation_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
BottomNavigationBar bottomNavigationBar = (BottomNavigationBar) findViewById(R.id.bottom_navigation_bar);
bottomNavigationBar
.addItem(new BottomNavigationItem(R.drawable.ic_home_white_24dp, "Home"))
.addItem(new BottomNavigationItem(R.drawable.ic_book_white_24dp, "Books"))
.addItem(new BottomNavigationItem(R.drawable.ic_music_note_white_24dp, "Music"))
.addItem(new BottomNavigationItem(R.drawable.ic_tv_white_24dp, "Movies & TV"))
.addItem(new BottomNavigationItem(R.drawable.ic_videogame_asset_white_24dp, "Games"))
.initialise();
i've made a private class which uses a gridview and a menu resource:
private class BottomBar {
private GridView mGridView;
private Menu mMenu;
private BottomBarAdapter mBottomBarAdapter;
private View.OnClickListener mOnClickListener;
public BottomBar (@IdRes int gridviewId, @MenuRes int menuRes,View.OnClickListener onClickListener) {
this.mGridView = (GridView) findViewById(gridviewId);
this.mMenu = getMenu(menuRes);
this.mOnClickListener = onClickListener;
this.mBottomBarAdapter = new BottomBarAdapter();
this.mGridView.setAdapter(mBottomBarAdapter);
}
private Menu getMenu(@MenuRes int menuId) {
PopupMenu p = new PopupMenu(MainActivity.this,null);
Menu menu = p.getMenu();
getMenuInflater().inflate(menuId,menu);
return menu;
}
public GridView getGridView(){
return mGridView;
}
public void show() {
mGridView.setVisibility(View.VISIBLE);
mGridView.animate().translationY(0);
}
public void hide() {
mGridView.animate().translationY(mGridView.getHeight());
}
private class BottomBarAdapter extends BaseAdapter {
private LayoutInflater mInflater;
public BottomBarAdapter(){
this.mInflater = LayoutInflater.from(MainActivity.this);
}
@Override
public int getCount() {
return mMenu.size();
}
@Override
public Object getItem(int i) {
return mMenu.getItem(i);
}
@Override
public long getItemId(int i) {
return 0;
}
@Override
public View getView(int i, View view, ViewGroup viewGroup) {
MenuItem item = (MenuItem) getItem(i);
if (view==null){
view = mInflater.inflate(R.layout.your_item_layout,null);
view.setId(item.getItemId());
}
view.setOnClickListener(mOnClickListener);
view.findViewById(R.id.bottomnav_icon).setBackground(item.getIcon());
((TextView) view.findViewById(R.id.bottomnav_label)).setText(item.getTitle());
return view;
}
}
your_menu.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/item1_id"
android:icon="@drawable/ic_item1"
android:title="@string/title_item1"/>
<item android:id="@+id/item2_id"
android:icon="@drawable/ic_item2"
android:title="@string/title_item2"/>
...
</menu>
and a custom layout item your_item_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="16dp">
<ImageButton android:id="@+id/bottomnav_icon"
android:layout_width="24dp"
android:layout_height="24dp"
android:layout_gravity="top|center_horizontal"
android:layout_marginTop="8dp"
android:layout_marginBottom="4dp"/>
<TextView android:id="@+id/bottomnav_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal"
android:layout_marginBottom="8dp"
android:layout_marginTop="4dp"
style="@style/mystyle_label" />
</LinearLayout>
usage inside your mainactivity:
BottomBar bottomBar = new BottomBar(R.id.YourGridView,R.menu.your_menu, mOnClickListener);
and
private View.OnClickListener mOnClickListener = new View.OnClickListener() {
@Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.item1_id:
//todo item1
break;
case R.id.item2_id:
//todo item2
break;
...
}
}
}
and in layout_activity.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
...
<FrameLayout android:id="@+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
<GridView android:id="@+id/bottomNav"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/your_background_color"
android:verticalSpacing="0dp"
android:horizontalSpacing="0dp"
android:numColumns="4"
android:stretchMode="columnWidth"
app:layout_anchor="@id/fragment_container"
app:layout_anchorGravity="bottom"/>
</android.support.design.widget.CoordinatorLayout>
I think this is also be useful.

It's https://github.com/roughike/BottomBar ported to C# for Xamarin developers
There is a new official BottomNavigationView in version 25 of the Design Support Library
https://developer.android.com/reference/android/support/design/widget/BottomNavigationView.html
add in gradle
compile 'com.android.support:design:25.0.0'
XML
<android.support.design.widget.BottomNavigationView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:design="http://schema.android.com/apk/res/android.support.design"
android:id="@+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
design:menu="@menu/my_navigation_items" />
This library, BottomNavigationViewEx, extends Google's BottomNavigationView. You can easily customise Google's library to have bottom navigation bar the way you want it to be. You can disable the shifting mode, change visibility of the icons and texts and so much more. Definitely try it out.
I have referred this github post and I have set the three layouts for three fragment pages in bottom tab bar.
FourButtonsActivity.java:
bottomBar.setFragmentItems(getSupportFragmentManager(), R.id.fragmentContainer,
new BottomBarFragment(LibraryFragment.newInstance(R.layout.library_fragment_layout), R.drawable.ic_update_white_24dp, "Recents"),
new BottomBarFragment(PhotoEffectFragment.newInstance(R.layout.photo_effect_fragment), R.drawable.ic_local_dining_white_24dp, "Food"),
new BottomBarFragment(VideoFragment.newInstance(R.layout.video_layout), R.drawable.ic_favorite_white_24dp, "Favorites")
);
To set the badge count :
BottomBarBadge unreadMessages = bottomBar.makeBadgeForTabAt(1, "#E91E63", 4);
unreadMessages.show();
unreadMessages.setCount(4);
unreadMessages.setAnimationDuration(200);
unreadMessages.setAutoShowAfterUnSelection(true);
LibraryFragment.java:
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class LibraryFragment extends Fragment {
private static final String STARTING_TEXT = "Four Buttons Bottom Navigation";
public LibraryFragment() {
}
public static LibraryFragment newInstance(int resource) {
Bundle args = new Bundle();
args.putInt(STARTING_TEXT, resource);
LibraryFragment sampleFragment = new LibraryFragment();
sampleFragment.setArguments(args);
return sampleFragment;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = LayoutInflater.from(getActivity()).inflate(
getArguments().getInt(STARTING_TEXT), null);
return view;

Inside onCreate() method,
BottomNavigationView navigation = (BottomNavigationView)findViewById(R.id.navigation);
//Dont forgot this line
BottomNavigationViewHelper.disableShiftMode(navigation);
And Create class as below.
public class BottomNavigationViewHelper {
public static void disableShiftMode(BottomNavigationView view) {
BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
try {
Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
shiftingMode.setAccessible(true);
shiftingMode.setBoolean(menuView, false);
shiftingMode.setAccessible(false);
for (int i = 0; i < menuView.getChildCount(); i++) {
BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
//noinspection RestrictedApi
item.setShiftingMode(false);
// set once again checked value, so view will be updated
//noinspection RestrictedApi
item.setChecked(item.getItemData().isChecked());
}
} catch (NoSuchFieldException e) {
Log.e("BNVHelper", "Unable to get shift mode field", e);
} catch (IllegalAccessException e) {
Log.e("BNVHelper", "Unable to change value of shift mode", e);
}
}
}
You can create the layouts according to the above-mentioned answers If anyone wants to use this in kotlin:-
private val mOnNavigationItemSelectedListener = BottomNavigationView.OnNavigationItemSelectedListener { item ->
when (item.itemId) {
R.id.images -> {
// do your work....
return@OnNavigationItemSelectedListener true
}
R.id.videos ->
{
// do your work....
return@OnNavigationItemSelectedListener true
}
}
false
}
then in oncreate you can set the above listener to your view
mDataBinding?.navigation?.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener)
