Android Weather App: Hooking Up the Model to the View section, Using a ProgressBar Challenge

Challenge Task 1 of 3

We've added a ProgressBar (spinner) to the Activity for when movie data is being loaded. Inject it using Butter Knife, just like the other member variables. Name it mProgressBar and use progressBar as the ID.

This is the line that's needed (which you could sort of figure out if you read threw the question a few dozen times):

@InjectView(R.id.progressBar) ProgressBar mProgressBar;

..which goes right after the other two @InjectView lines.

On to the next challenge..

Challenge Task 2 of 3

We want to display the progress bar while the network call is executing. Add the line of code to show it in the getMovieInfo() method.

Here's the getMovieInfo() code (with the needed line added):

    public void getMovieInfo() {
        if (isNetworkAvailable()) {
            // Some code omitted. Show the progress bar!
          mProgressBar.setVisibility(View.VISIBLE);
        }
    }

Proceeding onward to the final challenge..

Challenge Task 3 of 3

When the movie is retrieved we end up calling the updateDisplay() method. Hide the progress bar in there.

    public void updateDisplay(Movie movie) {
        // Some code omitted. Hide the progress bar.
        mProgressBar.setVisibility(View.INVISIBLE);
    }

By the way I found that line to set mProgressBar invisible code line in
