Question

I want to use multi choice spinner in mono for android.
I want to bind the countries to the spinner
Now in the normal spinner there is label with radio button.
But I want the label with the Checkbox.

can any one please help me.

AlertDialog.Builder alt_bld = new AlertDialog.Builder(
        CareCardActivity.this);
alt_bld.setTitle("Select Recepients");
alt_bld.setMultiChoiceItems(tempname, new boolean[tempname.length] , new DialogInterface.OnMultiChoiceClickListener() {

    public void onClick(DialogInterface dialog, int which,
            boolean isChecked) {
        // TODO Auto-generated method stub

    }
});
alt_bld.setPositiveButton("Ok", new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which) {

        // TODO Auto-generated method stub
        ListView list = ((AlertDialog) dialog).getListView();

        Log.v("LIST COUNT:: ", ""+list.getCount());
        for (int i = 0; i < list.getCount(); i++) {
            boolean checked = list.isItemChecked(i);

            if (checked) {
                sb.append(contactNumber[i]).append(";");
            }
        }
        sb = sb.replace(
                sb.length() - 1,
                sb.length(), "");
        txtPhoneNo.setText(sb.toString());
    }
});

alt_bld.setNegativeButton("Cancel",
        new DialogInterface.OnClickListener() {

            public void onClick(DialogInterface dialog, int which) {
                // TODO Auto-generated method stub

            }
        });

AlertDialog alert = alt_bld.create();
alert.show();

I have tried this code in the eclipse it is working fine in it, but I want to do it for Mono develop in C#.

Answer 1

call this function on click of button

ShowDialog(DIALOG_MULTIPLE_CHOICE); 

Add Following Code

protected override Dialog OnCreateDialog(int id)
    {
        switch (id) {
        case DATE_DIALOG_ID:
            return new DatePickerDialog(this, OnDateSet, date.Year, date.Month - 1, date.Day);



        case DIALOG_MULTIPLE_CHOICE: {
            var builder = new AlertDialog.Builder (this);
            //          builder.SetIcon (Resource.Drawable.ic_popup_reminder);
            builder.SetTitle ("Select Country");
            builder.SetMultiChoiceItems (countryName, new bool[countryName.Length], MultiListClicked);

            builder.SetPositiveButton ("ok", OkClicked);
            builder.SetNegativeButton ("Cancel", CancelClicked);

            return builder.Create ();
        }
        }
        return null;
    }
    private void MultiListClicked (object sender, DialogMultiChoiceClickEventArgs e)
    {
        Console.WriteLine ("countryMultiListClicked");
        if (e.IsChecked) {
            mSelectedItems.Add (countryName [(int)e.Which]);
            mSelectedItemsID.Add (countryID [(int)e.Which]);
        }
        else if (mSelectedItems.Contains(countryName [(int)e.Which]))
        {
            mSelectedItems.Remove(countryName [(int)e.Which]);
            mSelectedItemsID.Remove(countryID [(int)e.Which]);
        }
    }
    private void OkClicked (object sender, DialogClickEventArgs e)
    {
        Console.WriteLine ("countryOkClicked");

        String listString = "";
        for (int i =0; i<mSelectedItems.Count; i++) {
            listString += mSelectedItems [i] + ",";
        }
        if (listString.Length > 0) {
            listString = listString.Remove (listString.Length - 1);
        }
        et_country.Text = listString;

        listStringId = "";
        for (int i =0; i<mSelectedItemsID.Count; i++) {
            listStringId += mSelectedItemsID [i] + ",";
        }
        if (listStringId.Length > 0) {
            listStringId = listStringId.Remove (listStringId.Length - 1);
        }
        Console.WriteLine (listStringId);
    }
    private void CancelClicked (object sender, DialogClickEventArgs e)
    {
        Console.WriteLine("countryCancelClicked");
    }

This works fine ……..!
