AlarmManager Timer 定时

AlarmManager 

 手动设定手机的显示时间，只要大于或者等于AlarmManager 定的下次扫描时间就会触发闹钟

 

重复启动activity;

 

Intent intent = new Intent(context, TestActivity.class);
intent.putExtra("type", type);
PendingIntent pi = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 500, pi);

 

定时启动 ：

 

long time = "--------";

Intent intent = new Intent(TestReceiver.ACTION_ACTION);
PendingIntent pendingIntent = PendingIntent.getBroadcast(context,
				0,  intent , PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarm = (AlarmManager) context
				.getSystemService(Context.ALARM_SERVICE);
alarm.set(AlarmManager.RTC, time, pendingIntent);

 

取消定时：

 

Intent intent = new Intent(context, TestActivity.class);
intent.putExtra("type", type);
PendingIntent pi = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
AlarmManager alarmManager = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);
alarmManager.cancel(pi);

 

time 重复启动：没隔1秒启动。

    public void time (){
    	startTimeMilin = Calendar.getInstance().getTimeInMillis()+30*60*1000;
    	Timer timer = new Timer ();
    	timer.schedule(new TestTimerTask(), 0, 1000);
    }
    
    class TestTimerTask extends TimerTask{

		@Override
		public void run() {
			
			runOnUiThread(new Runnable() {
				
				public void run() {
					long leftTimesMilin = startTimeMilin-Calendar.getInstance().getTimeInMillis();
					long minitue = leftTimesMilin/1000/60;
					long seconds = leftTimesMilin/1000%60;
					String minStr = "";
					String secdStr = "";
					if (minitue<10) {
						minStr = "0"+minitue;
					}
					else {
						minStr = ""+minitue;
					}
					if (seconds<10) {
						secdStr = "0"+seconds;
					}
					else {
						secdStr = ""+seconds;
					}
					btn.setText(minStr+":"+secdStr);
					if(minitue<=0&&seconds<=0){
						btn.setText("btn");
						isBtnEnable = true;
						if(mTimer!=null){
							mTimer.cancel();
							mTimer = null;
						}
					}
				}
			});
		}
    	
    }

 

定时启动：1秒中后启动，

 

Timer timer2 = new Timer();
    	timer2.schedule(new TimerTask() {
			
			@Override
			public void run() {
				// TODO Auto-generated method stub
				
			}
		},1000);

 

 

 在service中重复启动：

 

Button bt1 = (Button) findViewById(R.id.bt1);
        bt1.setOnClickListener(new View.OnClickListener() {
			
			@Override
			public void onClick(View v) {
				Log.d("test", "___" + isTopActivy());
				ComponentName comp = new ComponentName("com.android.phone",
                "com.android.phone.EmergencyDialer");
					Intent intentM = new Intent();
					intentM.setComponent(comp);
					startActivity(intentM);

				Intent intent = new Intent();
				intent.setClass(PhoneDemoActivity.this, PhoneService.class);
//				intent.setAction(PhoneService.LOCK);
				intent.setAction(PhoneService.LOCK_TIME);
				startService(intent);
			}
		});
