I'm displaying the contacts in a Multi-select "Ok, Cancel" dialog box. I've
implemented Filterable for the adapter that displays the contacts in the
dialog. The problem is, once i try and select(check) a contact while i'm
using a type ahead, the check box in that particular position is checked and
not the contact.
The initial screen goes like
After type-ahead,
When I hit backspace, the screen appears as,
This is my activity.
Cursor c =
getContentResolver().query(People.CONTENT_URI, PROJECTION,
null, null,
Contacts.People.DEFAULT_SORT_ORDER);
startManagingCursor(c);
ListAdapter adapter1 = new
ContactListAdapter(this, c);
LayoutInflater inflater = (LayoutInflater)
this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = (View)
inflater.inflate(R.layout.list_view, null);
listView = (ListView)
view.findViewById(R.id.contactlist);
listView.setTextFilterEnabled(true);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setAdapter(adapter1);
listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
listView.setOnItemSelectedListener(this);
alertDialog.setView(view);
The adapter goes like,
public class ContactListAdapter extends CursorAdapter implements Filterable
{
public static final String[] PEOPLE_PROJECTION = new String[] { People._ID,
People.NAME, People.NUMBER };
public ContactListAdapter(Context context, Cursor c) {
super(context, c);
mContent = context.getContentResolver();
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
final LayoutInflater inflater = LayoutInflater.from(context);
final TextView view = (TextView) inflater.inflate(
android.R.layout.simple_list_item_multiple_choice, parent, false);
view.setText(cursor.getString(1));
return view;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
((TextView) view).setTag(cursor.getLong(0));
((TextView) view).setText(cursor.getString(1));
}
@Override
public String convertToString(Cursor cursor) {
return cursor.getString(1);
}
@Override
public Cursor runQueryOnBackgroundThread(CharSequence constraint) {
if (getFilterQueryProvider() != null) {
return getFilterQueryProvider().runQuery(constraint);
}
StringBuilder buffer = null;
String[] args = null;
if (constraint != null) {
buffer = new StringBuilder();
buffer.append("UPPER(");
buffer.append(Contacts.ContactMethods.NAME);
buffer.append(") GLOB ?");
args = new String[] { constraint.toString().toUpperCase() + "*" };
}
return mContent.query(Contacts.People.CONTENT_URI, PEOPLE_PROJECTION,
buffer == null ? null : buffer.toString(), args,
Contacts.People.DEFAULT_SORT_ORDER);
}
private ContentResolver mContent;
}
Any help in this is welcome.
