Question

我试图在滑动时实现音量更改，但最重要的是，我双击了实现手势的手势。我正在使用ExoPlayer 2和 com.google.android.exoplayer2.ui.PlayerView ，父级是 com.google.android.exoplayer2.ui.AspectRatioFrameLayout

我有code这样的人：

float y = motionEvent.getY();
int action = motionEvent.getActionMasked();
switch (action) {
    case MotionEvent.ACTION_DOWN:
        iY = y;
        break;
    case MotionEvent.ACTION_MOVE:
        float deltaY = motionEvent.getY() - iY;
        float absDeltaY = Math.abs(deltaY);
        if (isFullscreen) {
            Log.e("Delta", "Y: " + deltaY);
            Log.e("AbsDelta", "Y: " + absDeltaY);
            if (absDeltaY > 50) {
                Log.e("action", "Swipe !!!");
            }
        }
        break;
}

然后在onTouchListener中出现

：

gestureDetector.onTouchEvent(motionEvent);
return true;

gestureDetector是 GestureDetector.SimpleOnGestureListener ，它具有onDoubleTap和其他侦听器...

问题在于deltaY永远不会超过50个阈值，并且会停止并且需要重新触摸视图。另一方面，在与PlayerView及其父视图无关的视图上，它的作用就像是魅力。

P.S 这是多次触摸和滑动的日志记录：

PlayerView onTouch getY（）不会不断提供值
