Android - Wie man bestimmte Daten aus URL/JSON?

Also ich habe diesen code, der eine Seite mit einem ListView Suchfeld und ein button zum bestätigen der Suche, wenn Sie die Taste gedrückt, wird die ListView ist gefüllt mit Film-Namen aus der Rotten Tomatoes-API, Das problem ist, dass jemand half mir mit diesem code, und ich würde lieben, einige helfen, es brechen und verstehen es, Satz nach Satz, Mein Ziel ist ist es, den "Titel", "synopsis" und "Bild-url" ein Film, auf den geklickt wurde, in der Liste aus, und geben es mit der Absicht, meine andere Tätigkeit, sondern das ganze JSON und spezifische Daten Zeug, hat mich sehr verwirrt.

Link zu Rotten Tomatoes API-Dokumentation, das ist mein code:

public class MovieAddFromWeb extends Activity implements View.OnClickListener,
        OnItemClickListener {

    private TextView searchBox;
    private Button bGo, bCancelAddFromWeb;
    private ListView moviesList;
    public List<String> movieTitles;
    static final int ACTIVITY_WEB_ADD = 3;

    //the Rotten Tomatoes API key
    private static final String API_KEY = "8q6wh77s65aw435cab9rbzsq";

    //the number of movies to show in the list
    private static final int MOVIE_PAGE_LIMIT = 8;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.movie_add_from_web);

        InitializeVariables();

    }

    /*
     * Initializing the variables and creating the bridge between the views from
     * the xml file and this class
     */

    private void InitializeVariables() {

        searchBox = (EditText) findViewById(R.id.etSearchBox);

        moviesList = (ListView) findViewById(R.id.list_movies);

        bGo.setOnClickListener(this);
        bCancelAddFromWeb.setOnClickListener(this);
        moviesList.setOnItemClickListener(this);
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {

                            + searchBox.getText()
