Android本地媒體播放器未開啓完成方法

Question

本機Android媒體播放器在視頻運行持續時間後不會調用onCompletion方法。

我有一個活動播放單個視頻或視頻列表（m3u8文件）。視頻播放文件，因爲它應該，我也可以使用媒體控制器，但是，當視頻耗盡時，幾秒鐘後，他開始一個循環。除非用戶單擊（或雙擊）媒體控制器上的快進選項，否則onCompletion方法不會激活。

有沒有辦法讓onComplete方法在視頻用完時自動激活？ （我試過使用監聽器，不起作用）。指出我做錯了什麼也行得通。

這裏是處理視頻播放的活動：

public class VideoActivity extends ActionBarActivity implements MediaPlayer.OnCompletionListener { 
    private static final String TAG = VideoActivity.class.getSimpleName(); 

    private VideoView mVideoViewStream1; 
    ProgressDialog mDialog; 
    private String mURL; 
    private ChannelPlaylist mChannelPlaylist; 
    private int mIndex; 



    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_video); 

     // Validate internet connection 
     if (!Util.isDeviceConnected(this)) { 
      FragmentManager fm = getSupportFragmentManager(); 
      PopUpErrorFragment popupError = PopUpErrorFragment.newInstance(getString(R.string.errorInternetConnection)); 
      popupError.show(fm, PopUpErrorFragment.TAG); 
      finish(); 
     } 

     // Assign controls to their variable representations 
     mVideoViewStream1 = (VideoView) findViewById(R.id.vvVideo); 

     // Retrieve bundle data 
     Intent i = getIntent(); 
     Bundle bundle = i.getExtras(); 
     ChannelPlaylist channelPlaylist = bundle.getParcelable(KeyHelper.BUNDLE_CHANNEL_PLAYLIST); 

     if (channelPlaylist != null) { 
      this.mChannelPlaylist = channelPlaylist; 
      if (bundle.containsKey("index") && mIndex == 0) { 
       this.mIndex = bundle.getInt("index"); 
      } else { 
       if (this.mIndex == 0) { 
        this.mIndex = this.mChannelPlaylist.getIndex(); 
       } 
      } 

      this.mURL = this.mChannelPlaylist.getSchedule().get(mIndex).getStream_url(); 
     } else { 
      this.mURL = bundle.getString("url"); 
     } 

     progressDialog(); 
     standardAndroidPlayer(); 
    } 



    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.video, menu); 
     return true; 
    } 



    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 



    /***************************** CLASS METHODS **************************************************/ 



    /** 
    * Dismissess the dialog 
    */ 
    private void dismissDialog() { 
     if (this.mDialog != null) { 
      mDialog.dismiss(); 
     } 
    } 



    /** 
    * Standard android player 
    */ 
    private void standardAndroidPlayer() { 
     try { 
      // Start the MediaController 
      MediaController mediacontroller = new MediaController(this); 
      mediacontroller.setAnchorView(mVideoViewStream1); 

      // Get the URL from String VideoURL 
      mVideoViewStream1.setMediaController(mediacontroller); 
      // Set media player completion listener 
      mVideoViewStream1.setOnCompletionListener(this); 

      mVideoViewStream1.setVideoURI(Uri.parse(this.mURL)); 
      mVideoViewStream1.setOnPreparedListener(new MediaPlayer.OnPreparedListener() { 
       @Override 
       public void onPrepared(MediaPlayer mp) { 
        //Log.i(TAG, "Duration = " + mVideoViewStream1.getDuration()); 
        if (mp.isLooping()) mp.setLooping(false); 

       } 
      }); 
      mVideoViewStream1.requestFocus(); 
      mVideoViewStream1.start(); 
     } catch (Exception e) { 
      dismissDialog(); 
      Log.e(TAG, "Error" + e.getMessage()); 
      e.printStackTrace(); 

     } 

     dismissDialog(); 
    } 



    @Override 
    public void onCompletion(MediaPlayer mp) { 
     this.mIndex++; 
     if (this.mIndex < mChannelPlaylist.getSchedule().size()) { 
      this.mURL = this.mChannelPlaylist.getSchedule().get(this.mIndex).getStream_url(); 
      standardAndroidPlayer(); 
     } else { 
      finish(); 
     } 
    } 



    /** 
    * Creates a progress dialog 
    */ 
    private void progressDialog() { 
     // Create a progressbar 
     mDialog = new ProgressDialog(VideoActivity.this); 
     // Set progressbar title 
     mDialog.setTitle("Android Video Streaming Tutorial"); 
     // Set progressbar message 
     mDialog.setMessage("Buffering..."); 
     mDialog.setIndeterminate(false); 
     mDialog.setCancelable(false); 
     // Show progressbar 
     mDialog.show(); 
    } 
} 

編輯： 好，一些奇怪的原因，手機的方法不能在平板電腦使用時斷火，但是，它的作用。我無法在平板電腦上重現這種效果，也沒有在手機上獲得任何成功。它與Android的版本有什麼關係？由於在編寫監聽器時我沒有收到有關兼容性的任何警告，所以我沒有多少考慮。

試試這個。

mVideoViewStream1.setOnCompletionListener(new MediaPlayer.OnCompletionListener() { 
      public void onCompletion(MediaPlayer mp) { 

       finish(); 
      } 
     });
