私は、volleyを使用してURLから画像を取得しようとしていますが、機能していません データアプリの読み込み時にクラッシュします...しかし、imageloaderを削除すると evertythingが正しく読み込まれます。ここ Recyclerviewは画像をロードしていません
..
は私のアダプタクラスpublic class RecyclerViewDataAdapter extends RecyclerView.Adapter<RecyclerViewDataAdapter.ViewHolder> {
private Pants context;
public ImageLoader mImageLoader;
//List of superHeroes
List<ListOfData> superHeroes;
public RecyclerViewDataAdapter(List<ListOfData> superHeroes, Pants context){
super();
//Getting all the superheroes
this.superHeroes = superHeroes;
this.context = context;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recyclerview_row, parent, false);
ViewHolder viewHolder = new ViewHolder(v);
return viewHolder;
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
ListOfData superHero = superHeroes.get(position);
mImageLoader = MyApplication.getInstance(context).getImageLoader();
mImageLoader.get(superHero.getImageUrl(), ImageLoader.getImageListener(holder.imageView1, R.mipmap.ic_launcher, android.R.drawable.ic_dialog_alert));
holder.imageView1.setImageUrl(superHero.getImageUrl(), mImageLoader);
holder.textViewName1.setText(superHero.getName());
//holder.textViewRank.setText(String.valueOf(superHero.getRank()));
//holder.textViewRealName.setText(superHero.getRealName());
//holder.textViewCreatedBy.setText(superHero.getCreatedBy());
//holder.textViewFirstAppearance.setText(superHero.getFirstAppearance());
String powers = "";
/* for(int i = 0; i<superHero.getPowers().size(); i++){
powers+= superHero.getPowers().get(i);
}*/
//holder.textViewPowers.setText(powers);
}
@Override
public int getItemCount() {
return superHeroes.size();
}
class ViewHolder extends RecyclerView.ViewHolder{
public NetworkImageView imageView1;
public NetworkImageView imageView2;
public TextView textViewName1;
public TextView textViewName2;
public TextView textViewRank;
public TextView textViewRealName;
public TextView textViewCreatedBy;
public TextView textViewFirstAppearance;
public TextView textViewPowers;
public ViewHolder(View itemView) {
super(itemView);
imageView1 = (NetworkImageView) itemView.findViewById(R.id.thumbnail);
imageView2 = (NetworkImageView) itemView.findViewById(R.id.thumbnail2);
textViewName1 = (TextView) itemView.findViewById(R.id.category_title_one);
textViewName2 = (TextView) itemView.findViewById(R.id.category_title_two);
/* textViewRank= (TextView) itemView.findViewById(R.id.textViewRank);
