Czytam przykładowego kodu z Google, kod jest tak:powinien powinien zawierać odwołanie do adaptera?
public class AttractionListFragment extends Fragment {
...
private class AttractionAdapter extends RecyclerView.Adapter<ViewHolder>
implements ItemClickListener {
public List<Attraction> mAttractionList;
private Context mContext;
public AttractionAdapter(Context context, List<Attraction> attractions) {
super();
mContext = context;
mAttractionList = attractions;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Log.d("TEST", "onCreateViewHolder");
LayoutInflater inflater = LayoutInflater.from(mContext);
View view = inflater.inflate(R.layout.list_row, parent, false);
return new ViewHolder(view, this);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
Attraction attraction = mAttractionList.get(position);
holder.mTitleTextView.setText(attraction.name);
holder.mDescriptionTextView.setText(attraction.description);
Glide.with(mContext)
.load(attraction.imageUrl)
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.placeholder(R.drawable.empty_photo)
.override(mImageSize, mImageSize)
.into(holder.mImageView);
String distance =
Utils.formatDistanceBetween(mLatestLocation, attraction.location);
if (TextUtils.isEmpty(distance)) {
holder.mOverlayTextView.setVisibility(View.GONE);
} else {
holder.mOverlayTextView.setVisibility(View.VISIBLE);
holder.mOverlayTextView.setText(distance);
}
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public int getItemCount() {
return mAttractionList == null ? 0 : mAttractionList.size();
}
@Override
public void onItemClick(View view, int position) {
View heroView = view.findViewById(android.R.id.icon);
DetailActivity.launch(
getActivity(), mAdapter.mAttractionList.get(position).name, heroView);
}
}
private static class ViewHolder extends RecyclerView.ViewHolder
implements View.OnClickListener {
TextView mTitleTextView;
TextView mDescriptionTextView;
TextView mOverlayTextView;
ImageView mImageView;
ItemClickListener mItemClickListener;
public ViewHolder(View view, ItemClickListener itemClickListener) {
super(view);
mTitleTextView = (TextView) view.findViewById(android.R.id.text1);
mDescriptionTextView = (TextView) view.findViewById(android.R.id.text2);
mOverlayTextView = (TextView) view.findViewById(R.id.overlaytext);
mImageView = (ImageView) view.findViewById(android.R.id.icon);
mItemClickListener = itemClickListener;
view.setOnClickListener(this);
}
@Override
public void onClick(View v) {
mItemClickListener.onItemClick(v, getAdapterPosition());
}
}
interface ItemClickListener {
void onItemClick(View view, int position);
}
}
Można zobaczyć każdy ViewHolder posiada odniesienie (ItemClickListener) do adaptera, ponieważ adapter utrzymuje odniesienie do ViewHolder już, czy ktoś wie, czy tego rodzaju wdrożenie spowoduje wyciek pamięci? Proszę mnie poprawić, jeśli moje zrozumienie jest złe.
