There are a lot of discussions going on about the same subject, but after spending 4 hours here, I could not find a valid description or a link to make a Contact Picker with Checkbox.
I have an activity with DONE button and listview
with checkbox
. I have managed to show the contacts correctly. Now I want to return the selected contact phone numbers in a bundle
(I think the best way) so that I can get the list of numbers in onActivityResult()
. I am not sure of the way I am following is right or not.
Here is my code:
public class ContactPickerMulti extends ListActivity implements OnClickListener {
// List variables
public String[] Contacts = {};
public int[] to = {};
public ListView myListView;
Button save_button;
private TextView phone;
private String phoneNumber;
private Cursor cursor;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.contacts_multi);
// Initializing the buttons according to their ID
save_button = (Button) findViewById(R.id.contact_done);
// Defines listeners for the buttons
save_button.setOnClickListener(this);
Cursor mCursor = getContacts();
startManagingCursor(mCursor);
ListAdapter adapter = new SimpleCursorAdapter(
this,
android.R.layout.simple_list_item_multiple_choice,
mCursor,
Contacts = new String[] { ContactsContract.Contacts.DISPLAY_NAME },
to = new int[] { android.R.id.text1 });
setListAdapter(adapter);
myListView = getListView();
myListView.setItemsCanFocus(false);
myListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
}
private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME };
String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '"
+ ("1") + "'";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs,
sortOrder);
}
public void onClick(View src) {
Intent i;
switch (src.getId()) {
case R.id.contact_done:
SparseBooleanArray selectedPositions = myListView
.getCheckedItemPositions();
SparseBooleanArray checkedPositions = myListView
.getCheckedItemPositions();
if (checkedPositions != null) {
for (int k = 0; k < checkedPositions.size(); k++) {
if (checkedPositions.valueAt(k)) {
String name =
((Cursor)myListView.getAdapter().getItem(k)).getString(1);
Log.i("XXXX",name + " was selected");
}
}
}
break;
}
}
}
I want to send the numbers as array or list. What is the best way to do this? Any help or leading to right path is highly appreciated.
