我的Android心得（5）--响铃、震动、状态栏提示

目标：希望在特定情况下，通过响铃、震动、状态栏提示提醒用户

一、响铃

AudioManager能够调整响铃模式，音量等与音频相关的。

响铃实际靠MediaPlayer播放特定Uri下的音乐

// 使用来电铃声的铃声路径
Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE); 
// 如果为空，才构造，不为空，说明之前有构造过
if(mMediaPlayer == null)
	mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(context, uri);
mMediaPlayer.setLooping(true); //循环播放
mMediaPlayer.prepare();
mMediaPlayer.start();

二、震动

vibrator

vibrator = (Vibrator)mContext.getSystemService(mContext.VIBRATOR_SERVICE);
// 等待3秒，震动3秒，从第0个索引开始，一直循环
vibrator.vibrate(new long[]{3000, 3000}, 0);

三、状态栏提示

		m_Manager = (NotificationManager)mContext.getSystemService(Context.NOTIFICATION_SERVICE);
		//m_Manager.cancel(1023); //取消
		m_PendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0);
		m_Notification = new Notification();
		m_Notification.icon = R.drawable.flyheart; //设置图标
		m_Notification.tickerText = "未下拉提示栏时的浮动内容";
		m_Notification.setLatestEventInfo(mContext, "提示标题", "提示正文", m_PendingIntent);
		m_Manager.notify(1023, m_Notification); // 这个notification 的 id 设为1023

四、代码

public class RemindService extends Service{

	private MediaPlayer mMediaPlayer = null;
	private Vibrator vibrator;
	private Target target; // 关注对象的信息

	// 状态栏提示要用的
	private NotificationManager m_Manager;
	private PendingIntent m_PendingIntent;
	private Notification m_Notification;
	
	@Override
	public IBinder onBind(Intent intent) {
		// TODO Auto-generated method stub
		return null;
	}
	@Override
	public void onCreate() {
		// TODO Auto-generated method stub
		super.onCreate();
	}

	@Override
	public void onDestroy() {
		// TODO Auto-generated method stub
		
		if(mMediaPlayer != null){
			mMediaPlayer.stop();
			// 要释放资源，不然会打开很多个MediaPlayer
			mMediaPlayer.release();
		}
		if(vibrator != null){
			vibrator.cancel();
		}
		
		super.onDestroy();

	}

	/**
	 * 一启动就响铃，震动提醒
	 */
	@SuppressLint("NewApi")
	@SuppressWarnings("deprecation")
	@Override
	public int onStartCommand(Intent intent, int flags, int startId) {
		// TODO Auto-generated method stub
		
		Context mContext = getApplicationContext();
		if(target == null)
			target = new Target(mContext);
		
		if(target.getInfo(Target.setRemindRing).equals("false") == false){

			AudioManager audioManager = (AudioManager)mContext.getSystemService(Context.AUDIO_SERVICE);
			audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
			PlaySound(mContext);
		}
		
		if(target.getInfo(Target.setRemindVibrate).equals("false") == false){

			vibrator = (Vibrator)mContext.getSystemService(mContext.VIBRATOR_SERVICE);
			// 等待3秒，震动3秒，从第0个索引开始，一直循环
			vibrator.vibrate(new long[]{3000, 3000}, 0);
		}
		
		// 无论是否震动、响铃，都有状态栏提示
		m_Manager = (NotificationManager)mContext.getSystemService(Context.NOTIFICATION_SERVICE);
		m_Manager.cancel(1023);
		m_PendingIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0);
		m_Notification = new Notification();
		m_Notification.icon = R.drawable.flyheart;
		m_Notification.tickerText = "随时情感助手在呼唤你……";
		m_Notification.setLatestEventInfo(mContext, "随时情感助手", intent.getExtras().getString("remind_kind", ""), m_PendingIntent);
		m_Manager.notify(1023, m_Notification); // 这个notification 的 id 设为1023
		
		return super.onStartCommand(intent, flags, startId);
	}


		public  void PlaySound(final Context context) {
		
			Log.e("ee", "正在响铃");
			// 使用来电铃声的铃声路径
			Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE); 
			// 如果为空，才构造，不为空，说明之前有构造过
			if(mMediaPlayer == null)
				mMediaPlayer = new MediaPlayer();
			try {
				mMediaPlayer.setDataSource(context, uri);
				mMediaPlayer.setLooping(true); //循环播放
				mMediaPlayer.prepare();
				mMediaPlayer.start();
			} catch (IllegalArgumentException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (SecurityException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IllegalStateException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			} catch (IOException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
			
		}
