如何在mediaplayer播放时显示AlertDialog并使用它停止流式传输

Question

我首先提到我有一个带有几个项目的ListView。

我选择一个项目，我开始MediaPlayer的流媒体使用URL音频..

String url = "https://url/"+ MyFile + ".mp3"; 
    mPlayer = new MediaPlayer(); 
    mPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC); 
    try { 
     mPlayer.setDataSource(url); 
    } catch (IllegalArgumentException e) { 
     Toast.makeText(this, "You might not set the URI correctly!", Toast.LENGTH_LONG).show(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    try { 
     mPlayer.prepare(); 
    } catch (IllegalStateException e) { 
     Toast.makeText(this, "You might not set the URI correctly!", Toast.LENGTH_LONG).show(); 
    } catch (IOException e) { 
     Toast.makeText(this, "You might not set the URI correctly!", Toast.LENGTH_LONG).show(); 
    } 
    mPlayer.start(); 
    mPlayer.setOnCompletionListener(new OnCompletionListener() { 
     public void onCompletion(MediaPlayer mPlayer) { 
      mPlayer.release(); 



     } 
    }); 

我想，虽然同时MediaPlayer正在播放到显示AlertDialog关闭流这可能吗？

谢谢。

创建alertDialog和回调里面写来执行：

AlertDialog.Builder builder1 = new AlertDialog.Builder(context); 
builder1.setMessage("Stop the player?"); 
builder1.setCancelable(true); 

builder1.setPositiveButton(
    "Yes", 
    new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      mPlayer.release(); 
      dialog.cancel(); 
     } 
    }); 

builder1.setNegativeButton(
    "No", 
    new DialogInterface.OnClickListener() { 
     public void onClick(DialogInterface dialog, int id) { 
      dialog.cancel(); 
     } 
    }).show(); 

或者，如果你愿意，你可以创建自己的对话框布局（见https://stackoverflow.com/a/30388711/6726261）
