How to programmatically trigger the touch event in android?

// Obtain MotionEvent objectlong downTime = SystemClock.uptimeMillis();long eventTime = SystemClock.uptimeMillis() + 100;float x = 0.0f;float y = 0.0f;// List of meta states found here:     developer.android.com/reference/android/view/KeyEvent.html#getMetaState()int metaState = 0;MotionEvent motionEvent = MotionEvent.obtain(    downTime,     eventTime,     MotionEvent.ACTION_UP,     x,     y,     metaState);// Dispatch touch event to viewview.dispatchTouchEvent(motionEvent);

And here is the clean version:

public void TouchView(View view){    view.DispatchTouchEvent(MotionEvent.Obtain(SystemClock.UptimeMillis(), SystemClock.UptimeMillis(), (int)MotionEventActions.Down, 0, 0, 0));    view.DispatchTouchEvent(MotionEvent.Obtain(SystemClock.UptimeMillis(), SystemClock.UptimeMillis(), (int)MotionEventActions.Up, 0, 0, 0));}

PS: This is a xamarin android solution but you can easily modify it for java

To add to the excellent answer by @bstar55 above - if what you want is to create a 'tap' event, e.g, a user tapping on a view, then you need to simulate the user touching the screen and then removing their finger in a short time frame.

To do this you 'dispatch' an ACTION_DOWN MotionEvent followed after a short time by an ACTION_UP MotionEvent.

The following example, in Kotlin, is tested and worked reliably:

   //Create amd send a tap event at the current target loctaion to the PhotoView   //From testing (on an original Google Pixel) a tap event needs an ACTION_DOWN followed shortly afterwards by   //an ACTION_UP, so send both events   //First, create amd send the ACTION_DOWN MotionEvent   var originalDownTime: Long = SystemClock.uptimeMillis()   var eventTime: Long = SystemClock.uptimeMillis() + 100   var x = your_X_Value   var y = your_Y_Value    var metaState = 0   var motionEvent = MotionEvent.obtain(           originalDownTime,           eventTime,           MotionEvent.ACTION_DOWN,           x,           y,           metaState    )    var returnVal = yourView.dispatchTouchEvent(motionEvent)    Log.d(TAG,"rteurnVal: " + returnVal)    //Create amd send the ACTION_UP MotionEvent    eventTime= SystemClock.uptimeMillis() + 100    motionEvent = MotionEvent.obtain(           originalDownTime,           eventTime,           MotionEvent.ACTION_UP,           x,           y,           metaState     )     returnVal = yourView.dispatchTouchEvent(motionEvent)     Log.d(TAG,"rteurnVal: " + returnVal)
