I have implemented action bar SearchView , it's working fine but at the bottom of the screen a floating text popup is shown. See screenshot:
ListView Java class:
@Override
public boolean onQueryTextChange(String newText) {
if (TextUtils.isEmpty(newText)) {
mListView.clearTextFilter();
} else {
// EventAdapterView ca = (EventAdapterView)mListView.getAdapter();
// ca.getFilter().filter(newText.toString());
// Filter lFilter = mDataAdapter.getFilter();
// lFilter.filter("");
// following line was causing the ugly popup window.
mListView.setFilterText(newText.toString());
// EventAdapterView ca = (EventAdapterView)mListView.getAdapter();
// ca.getFilter().filter(newText.toString());
}
return true;
}
@Override
public boolean onQueryTextSubmit(String query) {
return true;
}
Adapter class
@Override
public Filter getFilter() {
/**
* A filter object which will filter message key
* */
Filter filter = new Filter() {
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
mEventUtil = (List<EventUtil>) results.values; // has the
// filtered
// values
notifyDataSetChanged(); // notifies the data with new filtered
// values. Only filtered values will be
// shown on the list
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults(); // Holds the
// results of a
// filtering
// operation for
// publishing
List<EventUtil> FilteredArrList = new ArrayList<EventUtil>();
if (mOriginalValues == null) {
mOriginalValues = new ArrayList<EventUtil>(mEventUtil); // mOriginalValues
}
if (mListItem == null) {
mListItem = new ArrayList<String>();
for (EventUtil message : mOriginalValues) {
mListItem.add(message.getEvent_Title());
}
}
/**
*
* If constraint(CharSequence that is received) is null returns
* the mOriginalValues(Original) values else does the Filtering
* and returns FilteredArrList(Filtered)
*
**/
if (constraint == null || constraint.length() == 0) {
/*
* CONTRACT FOR IMPLEMENTING FILTER : set the Original
* values to result which will be returned for publishing
*/
results.count = mOriginalValues.size();
results.values = mOriginalValues;
} else {
/* Do the filtering */
constraint = constraint.toString().toLowerCase();
for (int i = 0; i < mListItem.size(); i++) {
String data = mListItem.get(i);
if (data.toLowerCase().contains(constraint.toString())) {
FilteredArrList.add(mOriginalValues.get(i));
}
}
// set the Filtered result to return
results.count = FilteredArrList.size();
results.values = FilteredArrList;
}
return results;
}
};
return filter;
}
How can I remove this floating TextView ?
Try this
first disable TextFilterEnabled
on your ListView
yourListView.setTextFilterEnabled(false);
and filter your data like this:
android.widget.Filter filter = yourListAdapter.getFilter();
@Override
public boolean onQueryTextChange(String newText) {
// TODO Auto-generated method stub
filter.filter(newText);
return true;
}
that's it, and the search popup gone like a charm
If you are using a CursorLoader
then you should store the search query in a member variable for later use, instead of using the adapter's filter:
say,
private String mSearchQuery;
and then change the loader creation to work with the search query
@Override
public Loader<Cursor> onCreateLoader(final int id, final Bundle args) {
showProgress(true);
if (TextUtils.isEmpty(mSearchQuery)) {
return new CursorLoader(
mActivity,
CONTENT_URI,
PROJECTION,
DEFAULT_SELECTION,
null,
SORT_ORDER
);
}
mSearchQuery = "%" + mSearchQuery + "%";
return new CursorLoader(
mActivity,
CONTENT_URI,
PROJECTION,
// add the filtering criteria to the default.
DEFAULT_SELECTION + " AND " + COLUMN_A + " LIKE ?",
new String[]{mSearchQuery},
SORT_ORDER
);
}
and finally, make sure that you reload the loader
@Override
public boolean onQueryTextChange(String newText) {
mSearchQuery = newText;
// calls the above method
mActivity.getSupportLoaderManager().
restartLoader(0, null, this);
return true;
}
