按下后退按钮时如何停止播放音频? [英] How to stop audio from playing when back button is pressed?

问题描述

您好，这是我的代码:

   final ImageView imageView = (ImageView) findViewById(R.id.Image7);
   imageView.setImageResource(mFullSizeIds[position]);
   imageView.setOnClickListener(new View.OnClickListener() {

@Override
         public void onClick(View v) {
    MediaPlayer mp = MediaPlayer.create(Audio.this,mAudio[position]);  
    mp.start();

}

  });

现在，当用户点击图像时，此代码可以很好地播放音频，但是，当我想退出此活动并转到其他活动时，即使我按了Home键，音频仍在播放音轨还在玩.如何防止这种情况发生?当用户再次轻按图像或按下后退/主页"按钮时，是否可以停止播放曲目?

Now this code works fine to play the audio when the user taps the image, however when I want to exit this activity and go to a different activity, the audio track is still playing, even when I press the home key the audio is still playing. How can I prevent this from happening? Is there a way to stop the track from playing when the user taps the image again or presses the back/home button?

推荐答案

添加

   @Override
    public void onBackPressed ()
    {
      if (mp != null)
        mp.stop();
      super.onBackPressed();
    }

和

@Override
public void onPause ()
{
  if (mp != null)
  {
    mp.pause();
    mp.stop();
  }
  super.onPause();
}
