AsyncTask:异步线程可以去取消

@Override
protected void onCancelled() {
super.onCancelled();
cancel(true);
if (1 == searchIndex) {
ll_error.setVisibility(View.VISIBLE);
tv_nodata.setVisibility(View.GONE);
ll_friend.setVisibility(View.GONE);
}
}

> AsynckTask 异步线程加入Handler，传递消息

public abstract class MyAsynckTask {
private Handler handler=new Handler(){
public void handleMessage(android.os.Message msg) {
postTask();
};
};

public abstract void preTask();

public  abstract void doInBack();

public abstract void postTask();

public void execute(){
preTask();
new Thread(){
public void run() {
doInBack();
handler.sendEmptyMessage(0);
};
}.start();

}
}
