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, and when I looked it up, I found a whole bunch of code to add to your activity. And just for a simple button. I suppose thats not exactly what I am looking for? And if it really needs to be so much code for a single button, what is the best way to make the code more clear? Thank you, and sorry for being such an android newb.

Answer 1

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.
