在发表任何评论之前，我已经阅读了几个有关此问题的问题：
问题是我目前的活动是扩展YoutubeActivity。到目前为止，这是当前活动的样子：
public class MovieDetailsActivity extends YouTubeBaseActivity
implements YouTubePlayer.OnInitializedListener, OnEditorActionListener
{
*** SOME INITIALIZATION GOES HERE ***
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.movie_details);
movieDetails = (Movie) getIntent().getSerializableExtra("details");
youtubeVideo = movieDetails.trailer;
castList = movieDetails.castList;
findAllViewsById();
detailsTitleMovie.setText(movieDetails.originalName);
detailsRatingMovie.setText(movieDetails.rating);
detailsReleaseMovie.setText(movieDetails.released);
detailsRuntimeMovie.setText(movieDetails.runtime);
detailsSynopsisMovie.setText(movieDetails.overview);
*** OBVIOUSLY I NEED TO USE SOME SORT OF ITERATOR HERE ***
*** CASTLIST IS AN ARRAYLIST OF AN OBJECT ***
person = castList.get(0);
detailsFullnameCast.setText(person.castFullName);
*** END OF PROBLEM ***
String posterUrl = movieDetails.retrieveThumbnail();
if(posterUrl != null)
{
Bitmap bitmap = fetchBitmapFromCache(posterUrl);
if(bitmap == null)
{
new BitmapDownloaderTask(moviePoster).execute(posterUrl);
}else{
moviePoster.setImageBitmap(bitmap);
}
}else{
moviePoster.setImageBitmap(null);
}
if(youtubeVideo != null)
{
youtubePlayerView.initialize(YOUTUBE_API_KEY, this);
}else{
longToast("Aw... snapp....!");
}
/* BUTTON LISTENER */
cineplexButton.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
visitCinemaPage(CINEMA_TYPE_CINE);
}
});
blitzButton.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
visitCinemaPage(CINEMA_TYPE_BLI);
}
});
imdbButton.setOnClickListener(new OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
visitImdbMoviePage(movieDetails.imdbId);
}
});
//et = (EditText) findViewById(R.id.eturl);
//et.setOnEditorActionListener(this);
}
*** REST OF THE CODE OMITTED ***
但我想这样做：
public class MovieDetailsAdapter extends ArrayAdapter<Movie>{
private ArrayList<Movie> movieDataItems;
private Activity context;
public MovieDetailsAdapter(Activity context, int textViewResourceId, ArrayList<Movie> movieDataItems) {
super(context, textViewResourceId, movieDataItems);
// TODO Auto-generated constructor stub
this.context = context;
this.movieDataItems = movieDataItems;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View view = convertView;
if(view == null)
{
LayoutInflater vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
view = vi.inflate(layout.movie_details, null);
}
Movie movie = movieDataItems.get(position);
if(movie != null)
{
TextView titleTextView = (TextView) view.findViewById(R.id.detail_title_text_view);
titleTextView.setText(movie.originalName);
*** AND SO ON ***
}
return view;
}
}
以后上课将在我的活动课程中调用。
这是我的活动布局：
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
</LinearLayout>
</ScrollView>
所以基本上，我要问的是如何在同时扩展YoutubeActivity的同时将包含对象列表的数组列表填充到活动中。
感谢您的帮助......
