想了解android音乐播放器监听电话状态实现代码的相关内容吗,在本文为您仔细讲解android 播放器的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:android,播放器,下面大家一起来学习吧。

如下代码是监听电话的状态,代码简单不做介绍直接看代码:

复制代码 代码如下:

 private boolean mResumeAfterCall = false;
 private PhoneStateListener mPhoneStateListener = new PhoneStateListener() {
  @Override
  public void onCallStateChanged(int state, String incomingNumber) {
   if (state == TelephonyManager.CALL_STATE_RINGING) {
    AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
    int ringvolume = audioManager
      .getStreamVolume(AudioManager.STREAM_RING);
    if (ringvolume > 0) {
     mResumeAfterCall = (player.isPlaying() || mResumeAfterCall);
     try {
      stub.pause();
     } catch (RemoteException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
    }
   } else if (state == TelephonyManager.CALL_STATE_OFFHOOK) {
    // pause the music while a conversation is in progress
    mResumeAfterCall = (player.isPlaying() || mResumeAfterCall);
    try {
     stub.pause();
    } catch (RemoteException e) {
     // TODO Auto-generated catch block
     e.printStackTrace();
    }
   } else if (state == TelephonyManager.CALL_STATE_IDLE) {
    // start playing again
    if (mResumeAfterCall) {
     // resume playback only if music was playing
     // when the call was answered
     try {
      stub.resume();
     } catch (RemoteException e) {
      // TODO Auto-generated catch block
      e.printStackTrace();
     }
     mResumeAfterCall = false;
    }
   }
  }
 };

使用的时候呢,就在service 的oncreate 里面添加,如下:
复制代码 代码如下:

 public void onCreate() {
  player = new MediaPlayer();
  super.onCreate();
  TelephonyManager tmgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
  tmgr.listen(mPhoneStateListener, PhoneStateListener.LISTEN_CALL_STATE);
  IntentFilter filter = new IntentFilter();

  filter.addAction(SERVICECMD);
  filter.addAction(PAUSE_ACTION);
  receiver = new MusicServiceReceiver();
  registerReceiver(receiver, filter);
 }

在ondestroy 里面删除就可以了
复制代码 代码如下:

 public void onDestroy() {
  // Log.e(TAG, "onDestroy" +player.isPlaying() );
  // System.out.println("onDestroy");
  unregisterReceiver(receiver);
  player.release();
  player = null;

  TelephonyManager tmgr = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
  tmgr.listen(mPhoneStateListener, 0);
  super.onDestroy();
 }
