In my App (Material Design) I would like to show (say) 10 tabs. Of those tabs, the tab strip should hold e.g. 4. Now the tabstrip shows all tab-titles with 2 letters per tab. How can I create a sliding tabstrip? So I can scroll through the tab strip to the right tab? I know there is a custom made tabstrip, I would like to use as much as possible standard facilities.
1 - Setting up the tab pager:
private void setupTabPager() {
viewPager = (ViewPager) findViewById(R.id.pager);
final PagerAdapter adapter = new PagerAdapter(getSupportFragmentManager(), tabLayout.getTabCount());
viewPager.setAdapter(adapter);
viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
@Override
public void onTabSelected(TabLayout.Tab tab) {
// UserFeedback.show( "Tab selected: " + tab.getText());
viewPager.setCurrentItem(tab.getPosition());
}
@Override
public void onTabUnselected(TabLayout.Tab tab) {
}
@Override
public void onTabReselected(TabLayout.Tab tab) {
}
});
}
2 - Setting up the tab layout:
private void setupTablayout() {
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
if (tabLayout == null) {
return;
}
// tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
tabLayout.setTabGravity(TabLayout.MODE_SCROLLABLE);
tabLayout.addTab(tabLayout.newTab().setText("Folders"));
tabLayout.addTab(tabLayout.newTab().setText("Items"));
3 - The PageAdapter extending FragmentStatePagerAdapter:
public class PagerAdapter extends FragmentStatePagerAdapter {
int mNumOfTabs;
public PagerAdapter(FragmentManager fm, int NumOfTabs) {
super(fm);
this.mNumOfTabs = NumOfTabs;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case MainActivity.FRAGMENT_GROUPS_AND_ITEMS:
return new FragmentGroupsAndItems();
case MainActivity.FRAGMENT_FOLDERS:
return new FragmentFolders();
.... }
