AlertDialog's setCancelable(false) method not working

Is this your complete code? then please change your code for setting setCancelable(false) like this

void showDialog() {    DialogFragment newFragment = MyAlertDialogFragment.newInstance(            R.string..alert_dialog_two_buttons_title);    newFragment.setCancelable(false);    newFragment.show(getFragmentManager(), "dialog");}

Your dialog is set to no-cancelable, but your host fragment is still cancelable. Set your fragment with setCancelable(false).

Another working example:

Step 1

Create class:

public class DialogActivity extends android.app.DialogFragment {    @Override    public Dialog onCreateDialog(Bundle savedInstanceState) {        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());        builder.setMessage(R.string.myMessage);        setCancelable(false);        return builder.create();   }}

Step 2

Add method to your Activity:

private boolean showDialog() {    FragmentManager manager = getFragmentManager();    DialogActivity dialogActivity;    dialogActivity = new DialogActivity();    dialogActivity.show(manager, "DialogActivity");    return true;}

Step 3

Call showDialog() when you need to show dialog
