android 震动和提示音的实现代码

android的消息提示（震动和提示音），实现代码如下所示：

public class VibratorUtil {
  protected AudioManager audioManager;
  protected Vibrator vibrator;
  private Ringtone ringtone;
  private static final int MIN_TIME_OUT = 4000; //时间间隔
  long lastNotificationTime;
  public VibratorUtil() {
    audioManager = (AudioManager) MyApp.getContext().getSystemService(Context.AUDIO_SERVICE); //此方法是由Context调用的
    vibrator = (Vibrator) MyApp.getContext().getSystemService(Context.VIBRATOR_SERVICE); //同上
  }
  
  public void vibrateAndPlayTone() {
    if (System.currentTimeMillis() - lastNotificationTime < MIN_TIME_OUT) {
      return;
    }
    try {
      lastNotificationTime = System.currentTimeMillis();
      if (audioManager.getRingerMode() == AudioManager.RINGER_MODE_SILENT) {
 return;
      }
      long[] pattern = new long[]{0, 180, 80, 120};
      vibrator.vibrate(pattern, -1); //震动
      if (ringtone == null) {
 Uri notificationUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
 ringtone = RingtoneManager.getRingtone(MyApp.getContext(), notificationUri);
 if (ringtone == null) {
   return;
 }
      }
      if (!ringtone.isPlaying()) {
 ringtone.play();
 //判断手机品牌
 String vendor = Build.MANUFACTURER;
 if (vendor != null && vendor.toLowerCase().contains("samsung")) {
   Thread ctlThread = new Thread() {
     public void run() {
try {
  Thread.sleep(3000);
  if (ringtone.isPlaying()) {
    ringtone.stop();
  }
} catch (Exception e) {
}
     }
   };
   ctlThread.run();
 }
      }
    } catch (Exception e) {
      e.printStackTrace();
    }
  }
}
