The suggestions that appear in the default ListView beneath my SearchView contain text that is truncated. I would like the text to be displayed in its entirety (on multiple lines if necessary).
I have come up with two possible ways to solve this but, with no examples to be found on the net, I was hoping someone on here may be able to help...
Approach #1 / Q1: How can I directly access and modify the appearance of the TextViews that hold the SUGGEST_COLUMN_TEXT_1 and SUGGEST_COLUMN_TEXT_1 text?
Approach #2 / Q2: Alternatively, SearchView has a setSuggestionsAdapter(CursorAdapter adapter) method which looks like it may be (more?) suitable than approach #1. Although I have read up on CursorAdapters and have one already implemented in my app, I'm not sure how I would configure one for the SearchView (esp. in terms of accessing the cursor), so could anyone help me out with some general guidance or a skeleton example?
Here is the existing code from my SearchViewFragment class:
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;
}
}
Update: SOLVED!
Thanks to the accepted answer, I have created this code which is pretty clean and does the job well...
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);
}
*/
}
}
And here is my 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>
...the result is no text truncation. :-)
SearchableInfosays that it should be used for searching across different apps. If you have the cursor adapter up and running and displaying suggestions then it's simple to change the layout used ingetView. Perhaps you're currently using a defaultandroid.R.layout...one – Distraught
