Open the options menu programatically

Question

I like to call a menu already created an activity without using the button on the smartphone. How can I do it?

Answer 1

Two ways to do it:

Activity.getWindow().openPanel(Window.FEATURE_OPTIONS_PANEL, event);

The event argument is a KeyEvent describing the key used to open the menu, which can modify how the menu is displayed based on the type of keyboard it came from.

Or... by simulating that the user has pressed the button:

IWindowManager wManager = IWindowManager.Stub.asInterface(ServiceManager.getService("window"));
KeyEvent kd = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_SOFT_LEFT);
KeyEvent ku = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_SOFT_LEFT);
wManager.injectKeyEvent(kd.isDown(), kd.getKeyCode(), kd.getRepeatCount(), kd.getDownTime(), kd.getEventTime(), true);

Answer 2

Or just call Activity.openOptionsMenu()?
