私はオートコンプリートテキストビューを持っています。私はAPIから結果を得て、textchangedでアダプタに送信しています。Autocompletetextviewがカスタムアダプタでドロップダウンを表示しない
ここにアダプターがあります。
public class ProductSearchAdapter extends BaseAdapter implements Filterable {
private Context context;
private ArrayList<ProductListModel> originalList;
private ArrayList<ProductListModel> suggestions = new ArrayList<>();
private Filter filter = new CustomFilter();
public ProductSearchAdapter(Context context, ArrayList<ProductListModel> originalList) {
this.context = context;
this.originalList = originalList;
}
@Override
public int getCount() {
return suggestions.size(); // Return the size of the suggestions list.
}
@Override
public Object getItem(int position) {
return originalList.get(position).getName();
}
@Override
public long getItemId(int position) {
return 0;
}
/**
* This is where you inflate the layout and also where you set what you want to display.
* Here we also implement a View Holder in order to recycle the views.
*/
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = LayoutInflater.from(context);
ViewHolder holder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.product_search_row, parent, false);
holder = new ViewHolder();
holder.textViewProductName = (TextView) convertView.findViewById(R.id.textViewProductName);
holder.imageViewProductImage = (ImageView) convertView.findViewById(R.id.imageViewProductImage);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.textViewProductName.setText(originalList.get(position).getName());
Picasso.with(context)
.load(originalList.get(position).getImagesSmall().get(0).getSrc())
.into(holder.imageViewProductImage);
return convertView;
}
@Override
public Filter getFilter() {
return filter;
}
private static class ViewHolder {
ImageView imageViewProductImage;
TextView textViewProductName;
}
/**
* Our Custom Filter Class.
*/
private class CustomFilter extends Filter {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
suggestions.clear();
if (originalList != null && constraint != null) { // Check if the Original List and Constraint aren't null.
for (int i = 0; i < originalList.size(); i++) {
if (originalList.get(i).getName().toLowerCase().contains(constraint)) { // Compare item in original list if it contains constraints.
suggestions.add(originalList.get(i)); // If TRUE add item in Suggestions.
}
}
}
FilterResults results = new FilterResults(); // Create new Filter Results and return this to publishResults;
results.values = suggestions;
results.count = suggestions.size();
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
if (results.count > 0) {
notifyDataSetChanged();
} else {
notifyDataSetInvalidated();
}
}
}
}
ここで問題は、ドロップダウンが表示されないことです。一方、私はアレイアダプターと同じautocompletetextviewを試して、それが表示されます。 APIレスポンスで
autoCompleteTextViewSearch.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
if (charSequence.toString().length() > 0) {
hitSearchAPI(charSequence.toString());
}
}
@Override
public void afterTextChanged(Editable editable) {
}
});
：
final GsonBuilder gsonBuilder = new GsonBuilder();
final Gson gson = gsonBuilder.create();
productList = gson.fromJson(responseString, ProductListModel[].class);
arrayListProducts = new ArrayList<ProductListModel>(Arrays.asList(productList));
productsSearchAdapter = new ProductSearchAdapter(MainActivity.this, arrayListProducts);
autoCompleteTextViewSearch.setThreshold(1);
autoCompleteTextViewSearch.setAdapter(productsSearchAdapter);
同じのTextViewをカスタムアダプタで配列アダプタでの作業ではなく、ここで
は私がからAPIを呼び出しています活動の一環です。

試して、この 'autocompleteTextview.showDropDown（）と;' –
