Question

I need to detect WHEN the screen is touched. The onTouchEvent method only detects when the finger is moving. I need method which returns boolean value true, when the finger touches screen and returns false, when its not.

Answer 1

Here’s a very basic implementation of the onTouch method that modifies a boolean value to know if a the screen is touched. You may need to tweak it to suit your specific needs (and maybe handle multi touch)

private boolean mIsScreenTouched;

public boolean onTouch(View v, MotionEvent event) {

    switch (event.getAction()){
    case MotionEvent.ACTION_DOWN :
    case MotionEvent.ACTION_MOVE :
        mIsScreenTouched = true; 
        break; 
    case MotionEvent.ACTION_CANCEL :    
    case MotionEvent.ACTION_UP :
        mIsScreenTouched = false; 
        break; 
    }

    return true;
}
