Android编程实现震动与振铃的方法详解

boolean hasVibrator ()//检查硬件是否有振动器
void vibrate (long milliseconds)//控制手机制动milliseconds毫秒
void vibrate (long[] pattern, int repeat)//让手机以指定pattern模式震动。
void cancel ()//关闭震动

//震动milliseconds毫秒
public static void vibrate(final Activity activity, long milliseconds) {
    Vibrator vib = (Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
    vib.vibrate(milliseconds);
}
//以pattern[]方式震动
public static void vibrate(final Activity activity, long[] pattern,int repeat){
    Vibrator vib = (Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
    vib.vibrate(pattern,repeat);
}
//取消震动
public static void virateCancle(final Activity activity){
    Vibrator vib = (Vibrator) activity.getSystemService(Service.VIBRATOR_SERVICE);
    vib.cancel();
}

//开启震动
isVirating = true;
VirateUtil.virate(XXXActivity.this, new long[]{1000, 1000, 1000, 1000}, 0)
//关闭震动
if (isVirating) {
   isVirating = false;
   VirateUtil.virateCancle(XXXActivity.this);
}

void setDataSource (Context context , Uri uri)//根据Uri设置音频，当然还有其他几个重载的方法来指定特定的音频。
void setLooping (boolean looping)//设置是否循环播放
void prepare ()//让MediaPlayer真正去装载音频文件
void start ()//开始或恢复播放
void pause ()//暂停播放，调用start()可以恢复播放
void stop ()//停止播放
boolean isPlaying ()//是否正在播放
void release ()//释放与此MediaPlayer关联的资源

//开始播放
public static void playRing(final Activity activity){
    try {
      Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);//用于获取手机默认铃声的Uri
      mMediaPlayer = new MediaPlayer();
      mMediaPlayer.setDataSource(activity, alert);
      mMediaPlayer.setAudioStreamType(AudioManager.STREAM_RING);//告诉mediaPlayer播放的是铃声流
      mMediaPlayer.setLooping(true);
      mMediaPlayer.prepare();
      mMediaPlayer.start();
    } catch (Exception e) {
      e.printStackTrace();
    }
}
//停止播放
public static void stopRing(){
    if (mMediaPlayer!=null){
      if (mMediaPlayer.isPlaying()){
        mMediaPlayer.stop();
        mMediaPlayer.release();
      }
    }
}
