android - open navigation drawer by clicking the app icon?

Question

I use a navigation drawer in my app (the type of navigation that you open by sliding from the left side of the screen). Now, usually you can also open it by tapping the app icon

I ran into this issue also, assuming you already have an ActionBarDrawerToggle as @Kernald suggested, you need to add the following also to your Activity:

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Pass the event to ActionBarDrawerToggle, if it returns
    // true, then it has handled the app icon touch event
    if (mDrawerToggle.onOptionsItemSelected(item)) {
      return true;
    }
    // Handle your other action bar items...

    return super.onOptionsItemSelected(item);
}

This let's the toggle handle the icon button press on the ActionBar, causing the Drawer to slide out.
