How to open the options menu programmatically?

Question

I would like to open the optionsMenu programmatically without a click on the menu key from the user. How would I do that?

Answer 1

toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    toolbar.setTitleTextColor(0xFFFFFFFF);

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            toolbar.showOverflowMenu();
        }
    }, 100);

Answer 2

Put this line of code in your onResume(), this should help!

new Handler().postDelayed(new Runnable() { 
   public void run() { 
     openOptionsMenu(); 
   } 
}, 1000); 

Answer 3

For developers using the new Toolbar class of the Support Library, this is how it's done:

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

Answer 4

if using AppCompatActivity

getSupportActionBar().openOptionsMenu();

Answer 5

Or just call Activity.openOptionsMenu()?
