Android Studio - SoundPool - 从 ImageView 中取出手指后停止声音

Question

我有一个 ImageView。当我触摸它时，颜色会发生变化并且审查器声音开始播放。当我从 ImageView 上移开手指时，颜色再次改变并且声音应该停止播放。

一切正常，但声音不会停止。我尝试将 stop() 方法放入 OnClickListener 中，但它没有用。

当我从ImageView上松开手指时，如何停止声音？

btn_censor.setOnTouchListener(new OnTouchListener {
@override
public boolean onTouch(View v, MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
        btn_censor.setImageResource(R.drawable.btn_censor_focus);//Change color of the ImageView

        //Parameters for sound
        float vol = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        float maxVol = audioManager.getStreamVolume(AudioManager.STREAM_MUSIC);
        float leftVolume = vol / maxVol;
        float rightVolume = vol / maxVol;
        int priority = 1;
        int loop = -1; //infinite loop
        float normal_plaback_rate = 1f;

        soundPool.play(censor_ID, leftVolume, rightVolume, priority, loop, normal_playback_rate);//Play the sound
    } else if (event.getAction() == MotionEvent.ACTION_UP) {
        btn_censor.setImageResource(R.drawable.btn_censor);//Change colour of the ImageView
        soundPool.stop(censor_ID);//This should stop the sound
    }
    return false;
    };
};

您不应该为 stop() 传递 censor_ID。以下代码对我有用：

int streamID;

  @Override
  public boolean onTouch(View v, MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN) {
      streamID = soundPool.play(myLoadedSoundID, 1, 1, 0, 0, 1);
    } else if (event.getAction() == MotionEvent.ACTION_UP) {
      soundPool.stop(streamID);
    }
    return true;
  }
