Android loopj asynchttpclient return response

Question

In one of my project, I am using loopj asynchttpclient for communicating with my website. The communication part working well and getting response as well

My activity looks like

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);

        WebRequest test=new WebRequest();
        test.callService();
}

WebRequest Class as

public class WebRequest extends Activity {


    public void callService(){


        AsyncHttpClient client = new AsyncHttpClient();
        client.post("http://domain.com/dp/index.php", new AsyncHttpResponseHandler() {


            @Override
            public void onSuccess(String response) {
                Log.v("P",response);
            }

            @Override
            public void onFailure(Throwable e, String response) {
                 Log.v("PS",e.toString());
            }

    });
    }




}

I am confused how to return the response to the main activity, So that I can create the listview from that response.

I am new to this Please help me Thanks in advance

In your WebRequest class:

I don't think you want this class to extend Activity. You should only extend Activity when you're making a page to display in your app. You just want to execute some code, so extending Activity isn't needed.
Change your call service method to be static and take an AsyncHttpClient as a parameter.

Your WebRequest class should now look like this:

final class WebRequest {
    private AsyncHttpClient mClient = new AsyncHttpClient();
    public static void callService(AsyncHttpResponseHandler handler) {
        mClient.post("http://domain.com/dp/index.php", handler);
    }
}

In your main Activity:

Now all you have to do in your main activity is call the static method like this:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        WebRequest.callService(new AsyncHttpResponseHandler() {
            @Override
            public void onStart() {
                // Initiated the request
            }

            @Override
            public void onSuccess(String response) {
                // Successfully got a response
            }

            @Override
            public void onFailure(Throwable e, String response) {
                // Response failed :(
            }

            @Override
            public void onFinish() {
                // Completed the request (either success or failure)
            }
        });
}

Do whatever you need to do with the Views in your activity in the above callbacks. Hope this Helps!
