Several methods of delay execution in Android

The methods of delay execution include:

1, open a new thread, 2, the use of timers, 3, Message processing, 4, the use of Alarmmanager

First, open a new thread

New Thread (New Runnable () {

public void Run () {

Thread.Sleep (XXXX);

Handler.sendmessage (); Tell the main thread to perform a task

}

}). Start

Second, the use of timers

TimerTask task = new TimerTask () {

public void Run () {

Execute the Task

}

};

Timer timer = new timer ();

Timer.schedule (task, delay);

Third, message processing

New Handler (). postdelayed (New Runnable () {

public void Run () {

Execute the Task

}

}, delay);

Four, Alarmmanager, simple timing generally do not use this method

Alarmmanager, as the name implies, is a "reminder", a system-level cue service commonly used in Android, that broadcasts a specified intent for us at specific times. The simple thing is that we set a time, and then at that time, Alarmmanager broadcast a intent we set for us, usually we use pendingintent,pendingintent can be understood as intent package, The simple thing is to add a specified action on the intent. When using intent, we also need to perform startactivity, StartService, or sendbroadcast to make intent useful. And Pendingintent's words are to include this action inside.
