Open (overflow) menu programmatically

Question

I need to open the (overflow) menu programmatically on click of the home button.

As in other topics provided I have tried Activity.openOptionsMenu() and ActionBarActivity().getSupportActionBar().openOptionsMenu() but both times nothing happens.

Used Code:

@Override
public boolean onOptionsItemSelected(final MenuItem item) {
  ...
     case android.R.id.home:
        Log.i("HOME", "clicked");

        this.openOptionsMenu();
        break;
  ...
}

If you're using the new Toolbar class of the Support Library, do this:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.showOverflowMenu();

this returns false when I call it – Manny265 Sep 19 '16 at 00:05
check the source: https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/java/android/widget/Toolbar.java#514, are you sure you've properly set a menu to the toolbar? and that you're seeing an overflow button on the toolbar (3 dots)? – marmor Sep 19 '16 at 06:47

it means there's a race condition between inflating the toolbar, and your request to show the menu. try this: toolbar.post(new Runnable() { public void run() { toolbar.showOverflowMenu(); } }); – marmor Sep 19 '16 at 08:47
even better...cheers mate,u should probably make changes to the answer – Manny265 Sep 19 '16 at 21:13

If you don't have an ActionBar, the only way I found is to simulate a KeyEvent. This makes the options menu appears

    BaseInputConnection  mInputConnection = new BaseInputConnection( findViewById(R.id.main_content), true);
KeyEvent kd = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_MENU);
KeyEvent ku = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_MENU);
mInputConnection.sendKeyEvent(kd);
mInputConnection.sendKeyEvent(ku);

If you are using customized toolbar in you app, you can use the following way,

 new Handler().postDelayed(new Runnable() {
                @Override
                public void run() {
                    toolbar.showOverflowMenu();
                }
            }, 500);
