OnUp上GestureDetector事件 [英] OnUp event on GestureDetector

问题描述

我的问题很简单，在实施GestureListener的时候是在onUp事件？

My question is simple, where's the onUp event when implementing a GestureListener?

我有很多对gesturedetector事件，而不能只消耗听者的onUp事件，引起的事件之一是需要它的onSingleTapConfirmed

I has a lot of events on the gesturedetector, and cannot just consume the onUp event of the listener, cause one of events are the onSingleTapConfirmed that needs it.

推荐答案

尝试使用onFling（）。似乎是一个奇怪的名字，但对我来说，它的工作原理为onUp（）方法将逻辑地工作。或者试试这个方法...

Try using onFling(). Seems like a weird name but for me, it works as the onUp() method would logically work. Or try this method...

@Override
public boolean onTouchEvent(MotionEvent me) {

    Log.v("ADAM", "ontouch: " + me.getAction());

    if(me.getAction() == 0){
        Log.v("ADAM", "Down");
    }
    else if (me.getAction() == 1) {
        Log.v("ADAM", "Up");
    }
    else if (me.getAction() == 2) {
        Log.v("ADAM", "Scroll");
    }
    boolean detectedUp = event.getAction() == MotionEvent.ACTION_UP;
    if (!mGestureDetector.onTouchEvent(event) && detectedUp)
    {
        return onUp(event);
    }
    return true;
}
