Loading Image using picasso inside AsyncTask

Question

I\'m using picasso to load an image as a background for my activity, I want to use an AsyncTask, while the image is loading, when done the progress bar dismisses to give bet

Answer 1

You get error because picasso's load function is already async. So you can do this in UI thread like:

public void functionCalledFromUIThread(){

mProgressDialog = new ProgressDialog(MainActivity.this);
mProgressDialog.setMessage("Chargement...");
mProgressDialog.setIndeterminate(false);
mProgressDialog.show();
Picasso.with(MainActivity.this).load("http://tv2.orangeadd.com/mediacenter-data/ofc__bg_home.jpg").into(background,new com.squareup.picasso.Callback() {
             @Override
             public void onSuccess() {
                mProgressDialog.dismiss();
             }

             @Override
             public void onError() {
                mProgressDialog.dismiss();
             }
         }); 
}
