【问题描述】：
出现在我的SearchView 下方的默认ListView 中的建议包含被截断的文本。我希望文本完整显示（必要时显示多行）。
我想出了两种可能的方法来解决这个问题，但是在网上找不到任何例子，我希望这里的人可以提供帮助......
方法 #1 / Q1：如何直接访问和修改包含 SUGGEST_COLUMN_TEXT_1 和 SUGGEST_COLUMN_TEXT_1 文本的 TextView 的外观？
方法#2 / Q2：另外，SearchView 有一个setSuggestionsAdapter(CursorAdapter adapter) 方法，看起来它可能（更？）比方法#1 更合适。虽然我已经阅读了 CursorAdapters 并且已经在我的应用程序中实现了一个，但我不确定如何为 SearchView 配置一个（尤其是在访问光标方面），所以任何人都可以帮助我提供一些一般指导还是一个骨架示例？
这是我的 SearchViewFragment 类中的现有代码：
public class SearchViewFragment extends Fragment {
public SearchViewFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View fragmentView = inflater.inflate(R.layout.fragment_search_view, container, false);
// Use the Search Manager to find the SearchableInfo related to this Activity
SearchManager searchManager = (SearchManager)getActivity().getSystemService(Context.SEARCH_SERVICE);
SearchableInfo searchableInfo = searchManager.getSearchableInfo(getActivity().getComponentName());
// Bind the Activity's SearchableInfo to the Search View
SearchView searchView = (SearchView)fragmentView.findViewById(R.id.searchView);
searchView.setSearchableInfo(searchableInfo);
searchView.setIconifiedByDefault(false);
searchView.setSubmitButtonEnabled(true);
//searchView.setQueryRefinementEnabled(true);
return fragmentView;
}
}
更新：已解决！
感谢接受的答案，我创建了这段代码，它非常干净并且做得很好......
public class SearchViewFragment extends Fragment {
private static final String LOG_TAG = SearchViewFragment.class.getSimpleName();
public SearchViewFragment() {
}
@Override
public void onCreate(Bundle savedInstanceState) {
setRetainInstance(true); //todo - not working - Remember search term
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View fragmentView = inflater.inflate(R.layout.fragment_search_view, container, false);
// Use the Search Manager to find the SearchableInfo related to this Activity
SearchManager searchManager = (SearchManager)getActivity().getSystemService(Context.SEARCH_SERVICE);
SearchableInfo searchableInfo = searchManager.getSearchableInfo(getActivity().getComponentName());
// Bind the Activity's SearchableInfo to the Search View
final SearchView searchView = (SearchView)fragmentView.findViewById(R.id.searchView);
searchView.setSearchableInfo(searchableInfo);
searchView.setIconifiedByDefault(false);
searchView.setSubmitButtonEnabled(true);
//searchView.setQueryRefinementEnabled(true);
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String s) {
//DO whatever you want here on text submit in the search View
Log.d(LOG_TAG, "onQueryTextSubmit(" + s + ")");
return true;
}
@Override
public boolean onQueryTextChange(String textChange) {
Log.d(LOG_TAG, "onQueryTextChange(" + textChange + ")");
ContentResolver cr = getActivity().getContentResolver();
Uri uri = DbContentProvider.CONTENT_URI_REAL_PRODUCTS;
String[] projection = DbContentProvider.getProjectionIn(DbContentProvider.REAL_PRODUCTS_SUGGEST);
String selection = DbContentProvider.getSelection(false);
String[] selectionArgs = {Utilities.formatQueryString(textChange)};
String sortOrder = null;
Cursor cursor = cr.query(uri, projection, selection, selectionArgs, sortOrder);
Log.d(LOG_TAG, "Setting setSuggestionsAdapter. cursor: " + cursor);
searchView.setSuggestionsAdapter(new SearchSuggestionsAdapter(getActivity(), cursor));
return true;
}
});
return fragmentView;
}
private static class SearchSuggestionsAdapter extends SimpleCursorAdapter {
private static final String[] mVisible = {SearchManager.SUGGEST_COLUMN_TEXT_1, SearchManager.SUGGEST_COLUMN_TEXT_2};
private static final int[] mViewIds = {R.id.product_name, R.id.product_shelf};
public SearchSuggestionsAdapter(Context context, Cursor cursor) {
super(context, R.layout.search_view_suggestions, cursor, mVisible, mViewIds, 0);
}
/*
@Override
public void bindView(View view, Context context, Cursor cursor) {
Log.d(LOG_TAG, "bindView(" + view + ", " + context + ", " + cursor + ")");
super.bindView(view, context, cursor);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
Log.d(LOG_TAG, "newView(" + context + ", " + cursor + ", " + parent + ")");
return super.newView(context, cursor, parent);
}
*/
}
}
这是我的 search_view_suggestions.xml...
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin" >
<TextView
android:id="@+id/product_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Product Name placeholder"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/product_shelf"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Product Shelf placeholder" />
</LinearLayout>
...结果是没有文本截断。 :-)
【问题讨论】：
-
您是说您有一个可行的解决方案，但文本截断仍然是问题？
-
我的代码显示了建议，但它们被截断了。我需要一个解决截断问题的解决方案。
-
建议的数据来自哪里？
SearchableInfo的文档说它应该用于跨不同应用程序进行搜索。如果您已启动并运行光标适配器并显示建议，那么更改getView中使用的布局很简单。也许您当前正在使用默认的android.R.layout...一个
