我有一个 RecyclerView 和 EditText。我可以从 RecyclerView 中选择项目并获得正确的项目，除非它没有被过滤。在 EditText 中输入时，RecyclerView 列表会被过滤，当我从列表中选择任何项目时，它会显示实际的列表项目而不是选定的项目。
片段类：
public class RegionListFragment extends DialogFragment implements View.OnClickListener,
OnRecylerViewClickable {
private RecyclerView regionRecyclerView;
private ArrayList<RegionDetail> regionDetailArrayList = new ArrayList<>();
private GenericRegionListAdapter genericRegionListAdapter;
private Context context = this.getActivity();
private RecyclerView.LayoutManager mLayoutManager;
private View view;
private EditText editTextSearchView;
private DatabaseHandler spcl_databaseHandler;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
view = inflater.inflate(R.layout.spinner_fragment_list_screen, container, false);
databaseHandler = new DatabaseHandler(getActivity());
regionDetailArrayList = (ArrayList<RegionDetail>) spcl_databaseHandler.getAllRegionDetails();
editTextSearchView = (EditText) view.findViewById( R.id.search);
editTextSearchView.setHint(getString(R.string.region_search_hint));
mLayoutManager = new LinearLayoutManager(context);
regionRecyclerView = (RecyclerView) view.findViewById(R.id.recyclerView_Locations);
regionRecyclerView.setLayoutManager(mLayoutManager);
relativeLayoutBottom = (RelativeLayout) view.findViewById(R.id.rlBottom);
genericRegionListAdapter = new GenericRegionListAdapter(context, regionDetailArrayList, this, false);
regionRecyclerView.setAdapter(genericRegionListAdapter);
addTextListener();
return view;
}
public void addTextListener(){
editTextSearchView.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence query, int start, int before, int count) {
genericRegionListAdapter.getFilter().filter(query.toString());
}
});
}
@Override
public void onClick(View view) {
}
@Override
public void onRecyclerItemClicked(int position, String itemName, String itemID) {
Log.v("Region Name", " : " + regionDetailArrayList.get(position).getRegionName());
}
}
适配器类：
public class GenericRegionListAdapter extends RecyclerView.Adapter<GenericRegionListAdapter.DataObjectHolder>
implements Filterable {
private ArrayList<RegionDetail> originalArrayList;
private ArrayList<RegionDetail> filterArrayList;
private GenericRegionListAdapter.ValueFilter valueFilter;
private OnRecylerViewClickable onRecylerViewClickable;
private Context mContext = null;
@Override
public GenericRegionListAdapter.DataObjectHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.sd_custom_cardview_for_walk_list_item, parent, false);
GenericRegionListAdapter.DataObjectHolder dataObjectHolder = new GenericRegionListAdapter.DataObjectHolder(view);
return dataObjectHolder;
}
@Override
public Filter getFilter() {
if (valueFilter == null) {
valueFilter = new GenericRegionListAdapter.ValueFilter();
}
return valueFilter;
}
public class DataObjectHolder extends RecyclerView.ViewHolder{
TextView textViewWalkName;
public DataObjectHolder(View itemView) {
super(itemView);
mContext = itemView.getContext();
textViewWalkName = (TextView) itemView.findViewById(R.id.textView_Walk_Name);
}
}
public GenericRegionListAdapter(Context context, ArrayList<RegionDetail> detailsArrayList,
OnRecylerViewClickable onRecylerViewClickable, boolean doShowCheckbox) {
mContext = context;
this.originalArrayList = detailsArrayList;
this.filterArrayList = detailsArrayList;
this.onRecylerViewClickable = onRecylerViewClickable;
}
@Override
public void onBindViewHolder(final GenericRegionListAdapter.DataObjectHolder holder, final int position) {
holder.textViewWalkName.setText(originalArrayList.get(position).getRegionName());
holder.textViewWalkName.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
onRecylerViewClickable.onRecyclerItemClicked(position, originalArrayList.get(position).getRegionName(), originalArrayList.get(position).getRegionID());
}
});
}
// method to access in activity after updating selection
public ArrayList<RegionDetail> getRegionList() {
return originalArrayList;
}
@Override
public int getItemCount() {
return originalArrayList.size();
}
private class ValueFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
if (constraint != null && constraint.length() > 0) {
ArrayList<RegionDetail> filterList = new ArrayList<RegionDetail>();
for (int i = 0; i < filterArrayList.size(); i++) {
if ((filterArrayList.get(i).getRegionName().toUpperCase())
.contains(constraint.toString().toUpperCase())) {
RegionDetail listItem = new RegionDetail();
listItem.setRegionID(filterArrayList.get(i).getRegionID());
listItem.setRegionName(filterArrayList.get(i).getRegionName());
filterList.add(listItem);
}
}
results.count = filterList.size();
results.values = filterList;
} else {
results.count = filterArrayList.size();
results.values = filterArrayList;
}
return results;
}
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
originalArrayList = (ArrayList<RegionDetail>) results.values;
notifyDataSetChanged();
Log.v("Size", " : " + originalArrayList.size());
if (originalArrayList.size() == 0) {
new GlobalToast().showToastMessage(mContext, mContext.getResources().getString(R.string.no_records_found));
}
}
}
}
请帮我。
