DialogFragment setCancelable property not working

Question

I am working in an android application and am using a DialogFragment to show a dialog and I want to make that DialogFragment not cancelable. I have made the dialog cancelabl

Answer 1

In case you use alert builder (and probably in every case you wrap dialog inside a DialogFragment) to help build your dialog, please don't use getDialog().setCancelable(false) or Dialog.setCancelable(false) because it's not going to work. Use setCancelable(false) as shown in code below as it's mentioned in oficial android documentation:

public void setCancelable (boolean cancelable)

Added in API level 11 Control whether the shown Dialog is cancelable. Use this instead of directly calling Dialog.setCancelable(boolean), because DialogFragment needs to change its behavior based on this."

ref:http://developer.android.com/reference/android/app/DialogFragment.html#setCancelable(boolean)

public class MyDialogFragment extends DialogFragment {

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        LayoutInflater inflater = getActivity().getLayoutInflater();
        View view = inflater.inflate(R.layout.dialog_layout, null, false);
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity())
                .setTitle("in case you want use a title").setView(view);

        AlertDialog alert = builder.create();
        // alert.setCancelable(false); <-- dont' use that instead use bellow approach
        setCancelable(false); <-  press back button not cancel dialog, this one works fine
        alert.setCanceledOnTouchOutside(false); <- to cancel outside touch

        return alert;
}
