I have implemented the Navigation Drawer into my new app. But I cannot get the App name from ActionBar to toggle the Navigation Drawer. However, when I drag the navigation drawer, the ActionBar respond to this action by changing to an arrow.
Here is my code:
services_activity_main.xml
<LinearLayout
android:orientation="vertical"
android:id="@+id/container_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/title_bar_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
<LinearLayout
android:id="@+id/contents_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="32dp"
android:layout_marginStart="10dp"
android:layout_marginEnd="10dp">
</LinearLayout>
<LinearLayout
android:id="@+id/navigation_bar_layout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
</LinearLayout>
<FrameLayout
android:id="@+id/services_navigation_drawer_layout"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start">
</FrameLayout>
</android.support.v4.widget.DrawerLayout>
services_fragment_navigation_drawer.xml
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/services_navigation_drawer_gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:numColumns="auto_fit"
android:horizontalSpacing="10dp"
android:verticalSpacing="10dp"
android:stretchMode="columnWidth"
android:gravity="center"
android:choiceMode="multipleChoice"
android:focusable="true"
android:focusableInTouchMode="true"
android:background="#EEE" />
