Simple usage of Android Asynctask

public class Weatherasynctask extends Asynctask<string, Integer, string> {public TextView t1=null;public Weatherasynctask (TextView t) {t1=t;} @Overrideprotected string Doinbackground (String ... params) {//TODO auto-generated method Stubreturn params[0];} @Overrideprotected void OnPostExecute (String result) {//TODO auto-generated method Stubsuper.onpostexecute (Result); T1.settext (result);}}

At the beginning there are three parameters, the first parameter is passed in parameters, such as URLs, etc., the second is generally progress can be saved, the third is the return value.

The simplest is to override these two methods, the first parameter of the first method is the passed in value, the first method returns the value is the second method to substitute the result.
