我有回收站视图，其中我获取了Web服务器上可用的文件广告文件夹列表。在Recycler视图中，我根据标志区分文件和文件夹。 问题出在搜索上。当我搜索文件夹时，它完美无缺。但是当我搜索文件资源时，图像集是文件夹，并且说明是空白的。 这就是发生的事情。
我的适配器代码
public class PersonalFolderAdapter extends RecyclerView.Adapter<PersonalFolderAdapter.LRViewHolder> {
Context context;
ArrayList<PersonalFolderModel> fileList , filterList;
private OnItemClickListener mOnItemClickListener;
private String DrivePath = Environment.getExternalStorageDirectory().toString() + File.separator + "Mobi" + File.separator + "Drive"+ File.separator + "Downloads";
public PersonalFolderAdapter(Context context, ArrayList<PersonalFolderModel> fileList, OnItemClickListener onItemClickListener) {
this.context = context;
this.fileList = fileList;
mOnItemClickListener = onItemClickListener;
this.filterList = new ArrayList<>();
this.filterList.addAll(fileList);
}
@Override
public LRViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
Context context = parent.getContext();
LayoutInflater inflater = LayoutInflater.from(context);
// Inflate the custom layout
View contactView = inflater.inflate(R.layout.raw_individual, parent, false);
// Return a new holder instance
return new LRViewHolder(contactView);
}
@SuppressLint("SetTextI18n")
@Override
public void onBindViewHolder(final LRViewHolder holder, @SuppressLint("RecyclerView") final int position) {
// Get the data model based on position
if (filterList.get(position) != null) {
boolean isFile=fileList.get(position).getType_flag().equalsIgnoreCase("0");
//if (fileList.get(position).getType_flag().equalsIgnoreCase("0")) {
holder.bt_folder.setImageResource(isFile?R.drawable.icons_file:R.drawable.folder);

insted of
<强>的fileList 获得（位置）.getType_flag（）equalsIgnoreCase。（＆＃34; 0＆＃34）;
应该是
onBindViewHolder中的<强> filterList 获得（位置）.getType_flag（）equalsIgnoreCase。（＆＃34; 0＆＃34）;
