J'essaie de faire une liste de films, mais il ne montre qu'un écran blanc avec le nom de l'application. Apparemment, j'ai un programme très similaire à celui-ci et il fonctionne parfaitement bien. Voici ce que j'obtiens lorsque je lance le programme.
W/OpenGLRenderer : Impossible de choisir la configuration avec EGL_SWAP_BEHAVIOR_PRESERVED, réessayer sans...
J'ai trouvé quelqu'un qui dit que cette erreur se produit s'il y a une erreur dans les codes xml, mais je vais quand même mettre mes codes java aussi.
public class MainActivity extends AppCompatActivity {
private ListView mListView;
private Context mContext;
ArrayList<Movie> movieList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = this;
final ArrayList<Movie> movieList = Movie.getMoviesFromFile("movies.json", this);
MovieAdapter adapter = new MovieAdapter(this, movieList);
mListView = findViewById(R.id.movie_list_view);
mListView.setAdapter(adapter);
mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
Movie selectedMovie = movieList.get(i);
Intent detailIntent = new Intent(mContext, MovieDetailActivity.class);
detailIntent.putExtra("title", selectedMovie.title);
detailIntent.putExtra("description", selectedMovie.description);
detailIntent.putExtra("poster", selectedMovie.poster);
startActivity(detailIntent);
}
});
}Voici mon adaptateur.
public class MovieAdapter extends BaseAdapter{
private Context mContext;
private ArrayList<Movie> mMovieList;
private LayoutInflater mInflater;
public MovieAdapter(Context mContext, ArrayList<Movie> mMovieList){
this.mContext = mContext;
this.mMovieList = mMovieList;
mInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount(){return mMovieList.size();}
@Override
public Object getItem(int pos){return mMovieList.get(pos);}
@Override
public long getItemId(int pos){return pos;}
@Override
public View getView(int pos, View convertView, ViewGroup parent){
ViewHolder holder;
if(convertView == null){
convertView = mInflater.inflate(R.layout.list_item_movie, parent, false);
holder = new ViewHolder();
holder.titleTextView = convertView.findViewById(R.id.title);
holder.charactersTextView = convertView.findViewById(R.id.main_characters);
holder.descriptionTextView = convertView.findViewById(R.id.description);
holder.thumbnailImageView = convertView.findViewById(R.id.poster);
convertView.setTag(holder);
} else{
holder = (ViewHolder)convertView.getTag();
}
TextView titleTextView = holder.titleTextView;
TextView descriptionTextView = holder.descriptionTextView;
TextView charactersTextView = holder.charactersTextView;
ImageView thumbnailImageView = holder.thumbnailImageView;
Movie movie = (Movie)getItem(pos);
titleTextView.setText(movie.title);
titleTextView.setTextSize(20);
charactersTextView.setText(movie.main_characters);
charactersTextView.setTextSize(13);
descriptionTextView.setText(movie.description);
descriptionTextView.setTextSize(9);
Picasso.with(mContext).load(movie.poster).into(thumbnailImageView);
return convertView;
}
private static class ViewHolder{
public TextView titleTextView;
public TextView descriptionTextView;
public ImageView thumbnailImageView;
public TextView charactersTextView;
}}
Et les suivants sont les codes xml.
