android - setSuggestionAdapter() 不适用于 android.support.v7.widget.SearchView

Question

我正在尝试通过以下方式在我的可搜索 Activity 中设置自定义搜索建议适配器 ( as explained in the documentation)

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.search_result_menu, menu);

    SearchManager searchManager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
    SearchView searchView = (SearchView) menu.findItem(R.id.search_result_search_widget).getActionView();
    searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));

    SuggestionCursorAdapter suggestionCursorAdapter = new SuggestionCursorAdapter(this, null);
    searchView.setSuggestionsAdapter(suggestionCursorAdapter);

    return true;
}

我的 SuggestionCursorAdapter.class 看起来像这样:

public class SuggestionCursorAdapter extends CursorAdapter {

public SuggestionCursorAdapter(Context context, Cursor c) {
    super(context, c, 0);
   }

@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
    return LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
   }

@Override
public void bindView(View view, Context context, Cursor cursor) {
    TextView text1 = (TextView) view.findViewById(R.id.list_item_text1);
    TextView text2 = (TextView) view.findViewById(R.id.list_item_text2);

    String text1String = cursor.getString(cursor.getColumnIndexOrThrow(SearchManager.SUGGEST_COLUMN_TEXT_1));
    String text2String = cursor.getString(cursor.getColumnIndexOrThrow(SearchManager.SUGGEST_COLUMN_TEXT_2));

    text1.setText(text1String);
    text2.setText(text2String);
   }
}

这会产生以下编译时不兼容类型错误:

Error: incompatible types: SuggestionCursorAdapter cannot be converted to CursorAdapter

我猜错误是由于我使用了 .setSuggestionAdapter() 不支持的 android.support.v7.widget.SearchView。所以我不得不改为使用我不想使用的 android.widget.SearchView。

有人知道我该如何克服这个问题吗？是否有替代 .setSuggestionAdapter() 的方法？

感谢您的任何想法和提示!

支持 SearchView 类使用支持 CursorAdapter 类，而不是框架 CursorAdapter。只需确保您在 SuggestionCursorAdapter 类中导入了正确的那个。

import android.support.v4.widget.CursorAdapter;
