Prevent dialog dismissal on screen rotation in Android

The best way to avoid this problem nowadays is by using a DialogFragment.

Create a new class which extends DialogFragment. Override onCreateDialog and return your old Dialog or an AlertDialog.

Then you can show it with DialogFragment.show(fragmentManager, tag).

Here’s an example with a Listener:

public class MyDialogFragment extends DialogFragment {

    public interface YesNoListener {
        void onYes();

        void onNo();
    }

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        if (!(activity instanceof YesNoListener)) {
            throw new ClassCastException(activity.toString() + " must implement YesNoListener");
        }
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        return new AlertDialog.Builder(getActivity())
                .setTitle(R.string.dialog_my_title)
                .setMessage(R.string.dialog_my_message)
                .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        ((YesNoListener) getActivity()).onYes();
                    }
                })
                .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {

                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        ((YesNoListener) getActivity()).onNo();
                    }
                })
                .create();
    }
}

And in the Activity you call:

new MyDialogFragment().show(getSupportFragmentManager(), "tag"); // or getFragmentManager() in API 11+
