如何在Android中使用AlarmManager创建自定义日历并更新日期/时间

Question

Like Digital clock or Analog Clock, Do we have anything to display the date inside of our application. This should change the date on every day which is similar to digital clock changes time for every second.

If there is no controller is available then how can we display the date inside of our app. And this should change whenever the mobile date changes.

Please help me on this.

Answer 1

You may need timer for this as follows ,

1. Initialize Timer,TimerTask and handler

    Timer timer; TimerTask timerTask; final Handler handler = new Handler(); 

2. Start timer within OnResume() and will repeat once a minute

    @Override protected void onResume() { super.onResume(); timer = new Timer(); timer.schedule(timerTask, 0, 60000); } 

3. Display the time

    public void setUpTimer() { timerTask = new TimerTask() { public void run() { handler.post(new Runnable() { public void run() { SimpleDateFormat sdf = new SimpleDateFormat(""EEE, d MMM yyyy HH:mm:ss Z""); String date = sdf.format(new Date()); textView.setText(date); } }); } }; }
