Waiting till the async task finish its work

Question

I\'m very new to programming and I have some doubts.

I have a AsyncTask which is I call as RunInBackGround.

and I start this proc

Answer 1

I think the easiest way is to create an interface to get the data from onpostexecute and run the Ui from interface :

Create an Interface :

public interface AsyncResponse {
    void processFinish(String output);
}

Then in asynctask

@Override
protected void onPostExecute(String data) {
    delegate.processFinish(data);
}

Then in yout main activity

@Override
public void processFinish(String data) {
     // do things

}
