无法控制exoplayer的音量和亮度

Question

在一些问题的帮助下，我设法使用 onTouchEvent 方法为我的视频播放器添加了音量和亮度控制。但是当我向上或向下滑动我的应用程序时关闭（它重新启动）。关于我的代码的任何帮助，为什么我无法使用 onTouchEvent 控制音量和亮度。

这是我的代码：

@Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()){
            case MotionEvent.ACTION_DOWN:
                tested_ok=false;
                if (event.getX() < (sWidth / 2)) {
                    intLeft = true;
                    intRight = false;
                } else if (event.getX() > (sWidth / 2)) {
                    intLeft = false;
                    intRight = true;
                }
                int upperLimit = (sHeight / 4) + 100;
                int lowerLimit = ((sHeight / 4) * 3) - 150;
                if (event.getY() < upperLimit) {
                    intBottom = false;
                    intTop = true;
                } else if (event.getY() > lowerLimit) {
                    intBottom = true;
                    intTop = false;
                } else {
                    intBottom = false;
                    intTop = false;
                }
                seekSpeed = (TimeUnit.MILLISECONDS.toSeconds(exoPlayer.getDuration()) * 0.1);
                diffX = 0;

                break;

        }
        return super.onTouchEvent(event);
    }

仅供参考：我无法创建日志，因为我没有模拟器。提前谢谢你的帮助。

编辑：当我向下滑动音量时，它会移动到零，它不会慢慢减小，只有降低音量才有效。

为了通过触摸控制亮度和音量，我设法找到了 https://github.com/moneytoo/Player，它让我可以使用更多功能来完成该功能，并使用了 exoplayer 库

和 exoplayer 一样易于构建。

无法控制exoplayer的音量和亮度
