Android loopj asynchttpclient return response

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!
