如何检测android双击？

Question

如何检测android中的双击？我实现了OnDoubleTapListener并写了这个:

public boolean onDoubleTapEvent(MotionEvent e) {
        // TODO Auto-generated method stub
        if(e.getAction() == 1){
            Toast.makeText(getApplicationContext(),"Double Tap", Toast.LENGTH_SHORT).show();
        }
        return true;
    }

但它没有用.这有什么不对？

Answer 1

public class GestureDoubleTap extends GestureDetector.SimpleOnGestureListener {

    @Override
    public boolean onDoubleTap(MotionEvent e) {
        //some logic
        return true;
    }

}

GestureDoubleTap gestureDoubleTap = new GestureDoubleTap();
gestureDetector = new GestureDetector(this/* context */, gestureDoubleTap);

view.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View view, MotionEvent motionEvent) {
        return gestureDetector.onTouchEvent(motionEvent);
    }

});
