嗨，我正在尝试使用MVVM制作片段，并尝试从我的API进行调用，以列出故事以及用户帖子/图片，但是目前这些故事运行良好，并且我可以看到它也从API获取了数据将数据保存到userpost / picture中，但是我没有将其插入视图中，希望这里有人可以帮助我：）
片段中的代码：
private ArrayList<StoryList> storyArrayList;
private ArrayList<FeedData> feedArrayList;
private FeedViewModel feedViewModel;
private StoryAdapter storyAdapter;
private FeedAdapter feedAdapter;
private LinearLayoutManager newsFeedLayoutManager;
private void setupView() {
mBinding.storyRecyler.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false));
storyArrayList = new ArrayList<>();
storyAdapter = new StoryAdapter(getActivity(), storyArrayList);
mBinding.storyRecyler.setAdapter(storyAdapter);
newsFeedLayoutManager = new LinearLayoutManager(getContext());
mBinding.recylerFeed.setLayoutManager(newsFeedLayoutManager);
feedArrayList = new ArrayList<>();
feedAdapter = new FeedAdapter(getActivity(), feedArrayList);
mBinding.recylerFeed.setAdapter(feedAdapter);
mBinding.recylerFeed.hasFixedSize();
mBinding.recylerFeed.setItemViewCacheSize(10);
}
@Override
public void storyresponse(Object object) {
if (object instanceof StoryResponse) {
StoryResponse response = (StoryResponse) object;
storyArrayList.addAll(response.getData());
storyAdapter.notifyDataSetChanged();
}
if (object instanceof FeedResponse) {
FeedResponse feedresponse = (FeedResponse) object;
feedArrayList.addAll(feedresponse.getFeeddata());
feedAdapter.notifyDataSetChanged();
}
}
以及适配器代码：
public class FeedAdapter extends RecyclerView.Adapter<FeedAdapter.ViewHolder> {
private final List<FeedData> feedList;
private Activity context;
private View.OnClickListener onClickListener;
public FeedAdapter(Activity context, List<FeedData> feedList) {
this.context = context;
this.feedList = feedList;
this.onClickListener = onClickListener;
}
public List<FeedData> getFeedData(){
return feedList;
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_feed_photo, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, int position) {
holder.mBinding.setFeed(feedList.get(position));
Boolean isLiked = holder.mBinding.getFeed().getIsLiked();
String username = holder.mBinding.getFeed().getUsername();
holder.mBinding.username.setText(username);
}
@Override
public int getItemCount() {
return feedList.size();
}
class ViewHolder extends RecyclerView.ViewHolder {
ListItemFeedPhotoBinding mBinding;
public ViewHolder(View itemView) {
super(itemView);
mBinding = DataBindingUtil.bind(itemView);
}
}
public interface ClickListener {
void onClick(View view, int position);
void onLongClick(View view, int position);
}
public static class RecyclerTouchListener implements RecyclerView.OnItemTouchListener {
private GestureDetector gestureDetector;
private FeedAdapter.ClickListener clickListener;
public RecyclerTouchListener(Context context, final RecyclerView recyclerView, final FeedAdapter.ClickListener clickListener) {
this.clickListener = clickListener;
gestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onSingleTapUp(MotionEvent e) {
return true;
}
@Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null) {
clickListener.onLongClick(child, recyclerView.getChildPosition(child));
}
}
});
}
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
View child = rv.findChildViewUnder(e.getX(), e.getY());
if (child != null && clickListener != null && gestureDetector.onTouchEvent(e)) {
clickListener.onClick(child, rv.getChildPosition(child));
}
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
}
}
