Navigation Drawer Icon (ic_drawer) not showing

Question

I am implementing a navigation drawer for my app. Now it works perfectly except for one small glitch. When I set the Navigation Drawer Icon (ic_drawer) to replace the regular "HomeAsUp" caret icon, I still get the arrow. The Nav Drawer icon does not show. I have implemented every method that was on the android developers website. But it doesn't seem to work.

Below is my code:

DrawerLayout mDrawerLayout; FrameLayout leftDrawer, rightDrawer, contentFrame; ActionBarDrawerToggle mDrawerToggle;  @Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_home);     initializeViews(); }  private void initializeViews() {     // TODO Auto-generated method stub     mDrawerLayout = (DrawerLayout) findViewById(R.id.mDrawerLayout);     mDrawerToggle = new ActionBarDrawerToggle(this,             mDrawerLayout, R.drawable.ic_drawer,             R.string.drawer_open_content_desc,             R.string.drawer_close_content_desc);      getActionBar().setHomeButtonEnabled(true);     getActionBar().setDisplayHomeAsUpEnabled(true);      mDrawerLayout.setDrawerListener(mDrawerToggle);      leftDrawer = (FrameLayout) findViewById(R.id.drawerLeft_frame);     rightDrawer = (FrameLayout) findViewById(R.id.drawerRight_frame);     contentFrame = (FrameLayout) findViewById(R.id.content_frame); }   @Override protected void onPostCreate(Bundle savedInstanceState) {     // TODO Auto-generated method stub     super.onPostCreate(savedInstanceState);     mDrawerToggle.syncState(); }  @Override public void onConfigurationChanged(Configuration newConfig) {     // TODO Auto-generated method stub     super.onConfigurationChanged(newConfig);     mDrawerToggle.onConfigurationChanged(newConfig); }  @Override public boolean onCreateOptionsMenu(Menu menu) {     // Inflate the menu; this adds items to the action bar if it is present.     getMenuInflater().inflate(R.menu.home, menu);     return true; }  @Override public boolean onOptionsItemSelected(MenuItem item) {     // TODO Auto-generated method stub     if (mDrawerToggle.onOptionsItemSelected(item)) {         return true;     }     return super.onOptionsItemSelected(item); } 

Answer 1

I know it is quite late to answer this but this would help someone atleast.

You should probably add these lines of code to show that navigation icon.

@Override protected void onPostCreate(Bundle savedInstanceState) {     super.onPostCreate(savedInstanceState);     // Sync the toggle state after onRestoreInstanceState has occurred.     mDrawerToggle.syncState(); }  @Override public void onConfigurationChanged(Configuration newConfig) {     super.onConfigurationChanged(newConfig);     mDrawerToggle.onConfigurationChanged(newConfig); } 

Answer 2

Simply put this code in your styles.xml file:

<item name="homeAsUpIndicator">@drawable/ic_drawer</item> <item name="android:homeAsUpIndicator">@drawable/ic_drawer</item> 

I had this same problem and this worked for me.

EDIT

Programmatically you can set: getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_drawer);
