要使用MergeCursor从SearchRecentSuggestionsProvider显示错误的字符串,您可以按照以下步骤进行操作:
public class CustomSearchSuggestionProvider extends SearchRecentSuggestionsProvider {
public static final String AUTHORITY = "com.example.app.CustomSearchSuggestionProvider";
public static final int MODE = DATABASE_MODE_QUERIES;
public CustomSearchSuggestionProvider() {
setupSuggestions(AUTHORITY, MODE);
}
}
AutoCompleteTextView autoCompleteTextView = findViewById(R.id.autoCompleteTextView);
SearchRecentSuggestions suggestions = new SearchRecentSuggestions(this,
CustomSearchSuggestionProvider.AUTHORITY, CustomSearchSuggestionProvider.MODE);
Cursor recentSuggestions = suggestions.getRecentSuggestions(null, null,
SearchRecentSuggestionsProvider.DATABASE_MODE_QUERIES);
CursorAdapter adapter = new SimpleCursorAdapter(this,
android.R.layout.simple_dropdown_item_1line, recentSuggestions,
new String[] { SearchManager.SUGGEST_COLUMN_TEXT_1 },
new int[] { android.R.id.text1 });
autoCompleteTextView.setAdapter(adapter);
在此示例中,我们使用SimpleCursorAdapter将搜索建议的结果显示在AutoCompleteTextView中。您可以根据需要更改适配器和布局。
请注意,此示例假设您已正确设置SearchRecentSuggestionsProvider和权限。确保您的SearchRecentSuggestionsProvider在查询方法中返回正确的搜索建议数据。
