You can "fake" a touch event like this:

MotionEvent event = MotionEvent.obtain(downTime, eventTime, action, x, y, metaState);
view.onTouchEvent(event);

API Docs:

Create a new MotionEvent, filling in a subset of the basic motion values. Those not specified here are: device id (always 0), pressure and size (always 1), x and y precision (always 1), and edgeFlags (always 0).

Parameters:

• downTime The time (in ms) when the user originally pressed down to start a stream of position events. This must be obtained from SystemClock.uptimeMillis().
• eventTime The the time (in ms) when this specific event was generated. This must be obtained from SystemClock.uptimeMillis().
• action The kind of action being performed -- one of either ACTION_DOWN, ACTION_MOVE, ACTION_UP, or ACTION_CANCEL.
• x The X coordinate of this event.
• y The Y coordinate of this event.
• metaState The state of any meta / modifier keys that were in effect when the event was generated.
