        mp.start（）;
        btnChapter.setEnabled（假）;
      }
  }    mp.setOnCompletionListener（新MediaPlayer.OnCompletionListener（）{      @覆盖
      公共无效onCompletion（MediaPlayer的MP）{
        mp.stop（）;

        btnChapter.setEnabled（真）;
        的System.out.println（音乐是在和按钮使!!!!!!）;
      }
    }）;
  }
}
 

解决方案

要prevent这个你应该使用服务用于播放声音的同时，你的活动被切换到后台。请参考Android的有关活动的生命周期文档，看看到底发生了什么： https://developer.android.com/training/basics/activity-lifecycle/index.html

I have created a media player . I run the application properly. But I want to resume my song when I restart my activity. Why does my audio restart when I restart my activity?

How can I do this? I don't understand. Can any one help me??

Here is my code.

public class Audio_Activity extends Activity {
  public void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);

    setContentView(R.layout.audio);
    init();

    mp=MediaPlayer.create(Audio_Activity.this,R.raw.ennamo_yadho);
    Log.e("Song is playing","in  Mediya Player ");

    if(mp!=null) {
      length=mp.getCurrentPosition();
      Log.e("Current ","Position -> " + length);

      if(length > 0){
        mp.seekTo(length);
        mp.start();
        btnChapter.setEnabled(false);
      }
  }

    mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

      @Override
      public void onCompletion(MediaPlayer mp) {
        mp.stop();
        mp.release();
        btnChapter.setEnabled(true);
        System.out.println("Music is over and Button is enable !!!!!!");
      }
    });
  }
}

解决方案

To prevent this you should use a service for playing sounds while your activity goes to background. Refer to the android's documentation about the life-cycle of an activity to see what actually happens: https://developer.android.com/training/basics/activity-lifecycle/index.html
