请建议我如何在RecyclerView`中添加标题。
我看了所有教程和有关堆栈溢出的建议,但是它们都已经过时了。
我有一个网格视图,我想在其中添加一张图片的标题,请帮助我
我已经为标题创建了名为top_view.xml
的布局,并且也将适配器命名为WordAdapeter
我们不能在WordAdapter中为标头添加一些代码吗?
public class WordAdapter extends RecyclerView.Adapter<WordAdapter.ViewHolder> {
private List<Word> wordList;
private OnNoteListener mOnNoteListener;
public boolean isHeader(int position) {
return position == 0;
}
public WordAdapter(List<Word> wordList, OnNoteListener onNoteListener) {
this.wordList = wordList;
this.mOnNoteListener = onNoteListener;
}
public WordAdapter(OnNoteListener onNoteListener) {
this(new ArrayList<Word>(), onNoteListener);
}
public void addItems(List<Word> items) {
wordList.addAll(items);
notifyDataSetChanged();
}
public void clear() {
wordList.clear();
notifyDataSetChanged();
}
@NonNull
@Override
public ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.home_item_view, viewGroup, false);
return new ViewHolder(view, mOnNoteListener);
}
@Override
public void onBindViewHolder(@NonNull ViewHolder viewholder, int position) {
int resource = wordList.get(position).getImageResource();
String title = wordList.get(position).getTitle();
viewholder.setData(resource, title);
}
@Override
public int getItemCount() {
return wordList.size();
}
static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
private ImageView imageView;
private TextView title;
private OnNoteListener onNoteListener;
public ViewHolder(@NonNull View itemView, OnNoteListener onNoteListener) {
super(itemView);
imageView = itemView.findViewById(R.id.imageView);
title = itemView.findViewById(R.id.word);
this.onNoteListener = onNoteListener;
itemView.setOnClickListener(this);
}
private void setData(int resource, String titleText) {
imageView.setImageResource(resource);
title.setText(titleText);
}
@Override
public void onClick(View view) {
onNoteListener.onNoteClick(getAdapterPosition());
}
}
public interface OnNoteListener {
void onNoteClick(int position);
}
}
