Question

In a function handling a registration form I want to set the visibility of button to invisible and the visibility of a progress bar to visible. The problem now is, that the following code which handles some OAuth requests seems to prevent the widgets to show their visibility exactly where I want them to.

Setting the visibility of the progressbar stops (is frozen?) until the oauth requests are finished. How can I fix that?! I think working with sleep()s, wait()s or timers would be a bad solution here…

private void registerOnce(){

    ProgressBar spinner = (ProgressBar) findViewById(R.id.progressBar);
    Button login = (Button) findViewById(R.id.buttonLogin);

    spinner.setVisibility(View.VISIBLE);
    login.setVisibility(View.INVISIBLE);

    // Here goes the code for some oauth requests
    // This code here seems to prevent setting the
    // the visibility where I want it to.

    spinner.setVisibility(View.INVISIBLE);
    login.setVisibility(View.VISIBLE);

}

Better to Use AsyncTask
in onPreExecute()

 spinner.setVisibility(View.VISIBLE);
    login.setVisibility(View.INVISIBLE);

in doInBackground

// Here goes the code for some oauth requests
    // This code here seems to prevent setting the
    // the visibility where I want it to.

And in onPostExecute

spinner.setVisibility(View.INVISIBLE);
    login.setVisibility(View.VISIBLE);
