Android Dialog, keep dialog open when button is pr

Question

I would like to keep my dialog open when I press a button. At the moment it's closing.

AlertDialog.Builder builder = new AlertDialog.Builder(this);

builder.setMessage("Are you sure you want to exit?")

   .setCancelable(false)
   .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            MyActivity.this.finish();
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            dialog.cancel();
       }
   });
AlertDialog alert = builder.create();

Answer 1

This is how I manage to create a persistent popup when changing password.

// Login Activity
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.SetIcon(Resource.Drawable.padlock);
alert.SetCancelable(false);

var changepass = LayoutInflater.From(this);
var changePassLayout = changepass.Inflate(Resource.Layout.ChangePasswordLayout, null);

alert.SetView(changePassLayout);

txtChangePassword = (EditText)changePassLayout.FindViewById(Resource.Id.txtChangePassword);
txtChangeRetypePassword = (EditText)changePassLayout.FindViewById(Resource.Id.txtChangeRetypePassword);

alert.SetPositiveButton("Change", delegate {
    // You can leave this blank because you override the OnClick event using your custom listener
});

alert.SetNegativeButton("Cancel", delegate {
    Toast.MakeText(this, "Change password aborted!", ToastLength.Short).Show();
});

AlertDialog changePassDialog = alert.Create();
changePassDialog.Show();

// Override OnClick of Positive Button
Button btnPositive = changePassDialog.GetButton((int)Android.Content.DialogButtonType.Positive);
btnPositive.SetOnClickListener(new CustomListener(changePassDialog, empDetailsToValidate.EmployeeID));

// My Custom Class
class CustomListener : Java.Lang.Object, View.IOnClickListener, IDialogInterfaceOnDismissListener
{
    AlertDialog _dialog;
    EditText txtChangePassword;
    EditText txtChangeRetypePassword;

    EmployeeDetails _empDetails;
    string _workingEmployeeID;

    public CustomListener(AlertDialog dialog, string employeeID)
    {
        this._dialog = dialog;
        this._workingEmployeeID = employeeID;
    }
    public void OnClick (View v)
    {
        _empDetails = new EmployeeDetails(v.Context);

        txtChangePassword = (EditText)_dialog.FindViewById (Resource.Id.txtChangePassword);
        txtChangeRetypePassword = (EditText)_dialog.FindViewById (Resource.Id.txtChangeRetypePassword);

        if (!(txtChangePassword.Text.Equals(txtChangeRetypePassword.Text))) {
            Show ();
            Toast.MakeText(v.Context, "Password not match.", ToastLength.Short).Show();
        } else if (txtChangePassword.Text.Trim().Length < 6) {
            Show ();
            Toast.MakeText(v.Context, "Minimum password length is 6 characters.", ToastLength.Short).Show();
        } else if ((txtChangePassword.Text.Equals(LoginActivity.defaultPassword)) || (txtChangePassword.Text == "" || txtChangeRetypePassword.Text == "")) {
            Show ();
            Toast.MakeText(v.Context, "Invalid password. Please use other password.", ToastLength.Short).Show();
        } else {
            int rowAffected = _empDetails.UpdatePassword(_workingEmployeeID, SensoryDB.PassCrypto(txtChangePassword.Text, true));
            if (rowAffected > 0) {
                Toast.MakeText(v.Context, "Password successfully changed!", ToastLength.Short).Show();
                _dialog.Dismiss();
            } else {
                Toast.MakeText(v.Context, "Cant update password!", ToastLength.Short).Show();
                Show();
            }
        }
    }
    public void OnDismiss (IDialogInterface dialog)
    {
        if (!(txtChangePassword.Text.Equals (txtChangePassword.Text))) {
            Show ();
        } else {
            _dialog.Dismiss();
        }
    }
    public void Show ()
    {
        _dialog.Show ();
    }
}

BTW, i use Mono for Android not Eclipse.
