Android handler (2)

Note: We create a handler object to call the POST method, and then pass it into a runnable object. This method does not create a new thread.

Handlerthread and logoff:Handlerthread is a subclass of thread.

The following is the application framework:

1. First create the handlerthread object

2. enable the new thread by using the start method of the handlerthread object

3. Create a class to inherit handler and call the constructor containing logoff.

Public class myhandler extends handler {

 Public myhandler (low.logoff ){
Super (logoff );
}

Public void handlermessage (Message MSG ){}

}

4. Create a myhandler instance and pass in the getlooper of the handlerthread instance as the parameter.

Myhandler handler = new myhandler (New handlerthread. getlooper ());

Message message = handler. obtainmessage ();

// The target is the handler object that obtains the message object.

Message. sendtotarget ();
