私はサードパーティのライブラリを使用して検索可能なスピナーを作成しています。私は私のアプリでライブラリクラス（SearchableListDialog、SearchableSpinner）を追加しました。すべてがうまくいっていますが、私が直面している問題の1つでもあります。検索ビューウィジェットでAbcを検索した場合、結果はAbcとしてフィルタリングされませんが、リストビューアイテムをクリックすると、 Abc。アイテムの位置が変更されているようですが、リストに検索可能な結果が表示されていません。私はどこが間違っているのか分からない。コードを何度も変更しましたが、望ましい結果を得られませんでした。検索可能なスピナーでSearchView.OnQueryTextListener（）を使用するには？
検索可能スピナーXMLコード：
<com.example.my.currencyconverterapp.activity.SearchableSpinner
android:id="@+id/spinner"
android:layout_below="@+id/rl_currency_converterted_data"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
これは、私が検索可能スピナーにアダプタを設定しています私の断片コードです。
countriesCustomAdapterInr = new CountriesCustomAdapterInr(getActivity(), R.layout.custom_spinner_items, arrayList,res);
spinner.setAdapter(countriesCustomAdapterInr);
assert spinner != null;
spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
@Override
public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
Toast.makeText(getActivity(), ""+arrayList.get(i).getFull_name()+i, Toast.LENGTH_LONG).show();
}
@Override
public void onNothingSelected(AdapterView<?> adapterView) {}
});
これは、サードパーティのSearchableSpinnerクラス：
public class SearchableSpinner extends android.support.v7.widget.AppCompatSpinner implements View.OnTouchListener,
SearchableListDialog.SearchableItem {
public static final int NO_ITEM_SELECTED = -1;
private Context _context;
private List _items;

private boolean _isDirty;
private ArrayAdapter _arrayAdapter;
private String _strHintText;

public SearchableSpinner(Context context) {
super(context);
this._context = context;
init();
}
public SearchableSpinner(Context context, AttributeSet attrs) {
super(context, attrs);
this._context = context;
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.SearchableSpinner);
final int N = a.getIndexCount();
for (int i = 0; i < N; ++i) {
int attr = a.getIndex(i);
if (attr == R.styleable.SearchableSpinner_hintText) {
_strHintText = a.getString(attr);
}
}
a.recycle();
init();
}
public SearchableSpinner(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
this._context = context;
init();
}
private void init() {
_items = new ArrayList();
_searchableListDialog = SearchableListDialog.newInstance
(_items);
_searchableListDialog.setOnSearchableItemClickListener(this);
setOnTouchListener(this);
_arrayAdapter = (ArrayAdapter) getAdapter();
if (!TextUtils.isEmpty(_strHintText)) {
ArrayAdapter arrayAdapter = new ArrayAdapter(_context, android.R.layout
.simple_list_item_1, new String[]{_strHintText});
_isFromInit = true;
setAdapter(arrayAdapter);
}
}
@Override
public boolean onTouch(View v, MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_UP) {
if (null != _arrayAdapter) {
// Refresh content #6
// Change Start
// Description: The items were only set initially, not reloading the data in the
// spinner every time it is loaded with items in the adapter.
_items.clear();
for (int i = 0; i < _arrayAdapter.getCount(); i++) {
_items.add(_arrayAdapter.getItem(i));
}
// Change end.
_searchableListDialog.show(scanForActivity(_context).getFragmentManager(), "TAG");
}
}
return true;
}
@Override
public void setAdapter(SpinnerAdapter adapter) {
if (!_isFromInit) {
_arrayAdapter = (ArrayAdapter) adapter;
if (!TextUtils.isEmpty(_strHintText) && !_isDirty) {
ArrayAdapter arrayAdapter = new ArrayAdapter(_context, android.R.layout
.simple_list_item_1, new String[]{_strHintText});
super.setAdapter(arrayAdapter);
} else {
super.setAdapter(adapter);
}
} else {
_isFromInit = false;
super.setAdapter(adapter);
}
}
@Override
public void onSearchableItemClicked(Object item, int position) {
setSelection(_items.indexOf(item));
if (!_isDirty) {
_isDirty = true;
setAdapter(_arrayAdapter);
setSelection(_items.indexOf(item));
}
}
public void setTitle(String strTitle) {
_searchableListDialog.setTitle(strTitle);
}
public void setPositiveButton(String strPositiveButtonText) {
_searchableListDialog.setPositiveButton(strPositiveButtonText);
}
public void setPositiveButton(String strPositiveButtonText, DialogInterface.OnClickListener onClickListener) {
_searchableListDialog.setPositiveButton(strPositiveButtonText, onClickListener);
}
public void setOnSearchTextChangedListener(SearchableListDialog.OnSearchTextChanged onSearchTextChanged) {
_searchableListDialog.setOnSearchTextChangedListener(onSearchTextChanged);
}
private Activity scanForActivity(Context cont) {
if (cont == null)
return null;
else if (cont instanceof Activity)
return (Activity) cont;
else if (cont instanceof ContextWrapper)
return scanForActivity(((ContextWrapper) cont).getBaseContext());
return null;
}
@Override
public int getSelectedItemPosition() {
if (!TextUtils.isEmpty(_strHintText) && !_isDirty) {
return NO_ITEM_SELECTED;
} else {
return super.getSelectedItemPosition();
}
}
@Override
public Object getSelectedItem() {
if (!TextUtils.isEmpty(_strHintText) && !_isDirty) {
return null;
} else {
return super.getSelectedItem();
}
}
}
これで、第三者SearchableListDialogクラス：ここOnQueryTextListener（）に動作していない細かい

。私を助けてください。私は試しましたが、解決策はありませんでした。誰でも助けてくれますか？上記、私は私のクエリを述べている。おかげ
ます。また、リストビューの代わりにスピナーを使用することができます@Kenjin、私はそれをテストし、それが動作します。あなたの質問があれば教えてください。 –
