I have an action bar that puts everything in a menu in the top right, which the user clicks and the menu options open up.

I inflate the action bar menu with this on

Answer 1

In my opinion

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    add_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onCreateDialog(getTaskId());
        }
    });
}
