AlertDialog SingleChoiceItems not working

Question

I'm trying to make a SingleChoiceItems AlertDialog with an OK and Cancel button which gives the user the option on a onItemLongClick from a ListView to 1.view the user's profile 2.send the user a message and 3.delete the user from the friends list.

I haven't done option 1 and 2 yet but I'm trying to make option 3 right now in which I included the Database delete method and a toast that says "friend removed" but when I select Option 3 and hit ok that row does not get deleted or I see the Toast saying the user was deleted.Here is my code for the Activity I'm using the Dialog.

public class PlayAFriend extends ListActivity {
    DBAdapter DBAdapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.list_items);
        final DBAdapter db = new DBAdapter(this);
        DBAdapter = db.open();
        ListView FriendLV = (ListView) findViewById(android.R.id.list);
        final Cursor friendslist = db.GetAllFriends();
        String[] from = new String[] { "FRIENDS" }; // your column/columns here
        int[] to = new int[] { R.id.textview_friends };

        @SuppressWarnings("deprecation")
        ListAdapter cursorAdapter = new SimpleCursorAdapter(this,
                R.layout.list_items, friendslist, from, to, 0);
        FriendLV.setAdapter(cursorAdapter);
        FriendLV.setLongClickable(true);

        FriendLV.setOnItemLongClickListener(new OnItemLongClickListener() {

            class CustomCursorAdapter extends CursorAdapter {
                public CustomCursorAdapter(Context context, Cursor c, int flags) {
                    super(context, friendslist, flags);
                    // TODO Auto-generated constructor stub
                    inflater = LayoutInflater.from(context);
                }

                LayoutInflater inflater;

                @Override
                public void bindView(View view, Context context,
                        Cursor friendslist) {

                    int row_id = ((com.fullfrontalgames.numberfighter.DBAdapter) friendslist)
                            .get("_id");

                }

                    View v = inflater.inflate(R.layout.list_items, parent,
                            false);
                    bindView(v, context, friendslist);
                    return v;
                }
            }

Answer 1

You have to save the choice when select a radio button, the other int parameter in the button does not represent the choice. Make int mChoice; a class member

public class PlayAFriend extends ListActivity {
DBAdapter DBAdapter;
int mChoice;
......
......

@Override
public Dialog onCreateDialog(final int id) {

    final DBAdapter db = new DBAdapter(this);
    db.open();
    switch (id) {
    case 0:
        return new AlertDialog.Builder(this)
        .setIcon(R.drawable.icon)
        .setTitle("Select an Option")
        .setSingleChoiceItems(items, id,
                new DialogInterface.OnClickListener() {

            @Override
            public void onClick(DialogInterface dialog,
                    int choice) {
                mChoice = choice; // save the choice

            }
        }

                )
                .setPositiveButton("Ok",
                        new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog,
                            int choice) {

                        // TODO Auto-generated method stub

                        if (mChoice == 0) {
                            Toast.makeText(getBaseContext(),
                                    "Test", Toast.LENGTH_SHORT)
                                    .show();
                        } else if (mChoice == 1) {
                            Toast.makeText(getBaseContext(),
                                    "Test2", Toast.LENGTH_SHORT)
                                    .show();

                        } else if (mChoice == 2) {
                            Toast.makeText(getBaseContext(),
                                    "Friend Removed",
                                    Toast.LENGTH_SHORT).show();
                            final TextView friends = (TextView) findViewById(R.id.textview_friends);
                            String deletedfriend = friends
                                    .getText().toString();

                            db.DeleteFriends(deletedfriend);

                        }

                    }

                })
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog,
                            int choice) {

                    }
                })

                .create();

    }
    return null;
}
