2,实现
- 1,Xml布局
- 2,Activity文件

- 3,第一个列表的Adapter文件
public class TouTiaoTwoMyAdapter extends MyItemTouchHandler.ItemTouchAdapterImpl {
private final LayoutInflater mLayoutInflater;
private Context mContext;
private ListmData;
AdapterCallBack mAdapterCallBack;
public TouTiaoTwoMyAdapter(Context context, List data,AdapterCallBack adapterCallBack) {
mContext = context;
mData = data;
this.mAdapterCallBack=adapterCallBack;
mLayoutInflater = LayoutInflater.from(context);
}
@Override
public void onItemMove(int fromPosition, int toPosition) {
}
/**禁止自动拖拽
* @return
*/
// @Override
// protected boolean autoOpenDrag() {
// return false;
// }
/**禁止滑动删除
* @return
*/
@Override
protected boolean autoOpenSwipe() {
return false;
}
@Override
public void onItemRemove(int position) {
}
@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = mLayoutInflater.inflate(R.layout.item_toutiao_one, parent, false);
return new ViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder,
@SuppressLint("RecyclerView") int position) {
if (holder instanceof ViewHolder) {
((ViewHolder) holder).tvTitle.setText(mData.get(position));
if (isDelete){
if (position > 1) {
((ViewHolder) holder).ivDelete.setVisibility(View.VISIBLE);
}
}else {
((ViewHolder) holder).ivDelete.setVisibility(View.GONE);
}
holder.itemView.setOnClickListener(view -> {
//点击监听
mAdapterCallBack.onItemClickListener((ViewHolder) holder,position);
});
// //长按点击监听
holder.itemView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View view) {
mAdapterCallBack.onItemLongClickListener((ViewHolder) holder,position);
return false;
}
});
}
}
private boolean isDelete;
public void showDeleteIcon(boolean isDelete){
this.isDelete = isDelete;
notifyDataSetChanged();
}
public interface AdapterCallBack{
void onItemClickListener(ViewHolder viewHolder,int pos);
boolean onItemLongClickListener(ViewHolder viewHolder,int pos);
}
@Override
public int getItemCount() {
return mData.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView tvTitle;
ImageView ivDelete;
public ViewHolder(View itemView) {
super(itemView);
tvTitle = itemView.findViewById(R.id.tv_item_toutiao_one_title);
ivDelete = itemView.findViewById(R.id.iv_item_toutiao_one_delete);
}
}
}
- 5,第二个列表的Adapter,普通的Adapter,随意写,赋值就可以
public class TouTiaoTwoAdapter extends BaseQuickAdapter {
public TouTiaoTwoAdapter(int layoutResId, @Nullable List data) {
super(layoutResId, data);
}
@Override
protected void convert(BaseViewHolder helper, String item) {
helper.setText(R.id.tv_item_toutiao_two_title,item);
}
}
- 6,两个列表用的Item布局基本一样
- 第一个item_toutiao_one:
- 第二个item_toutiao_two:
