Set title and (title) icon for a custom alert dialog

Question

I don't manage to set a neither a title nor a (title) icon to my custom alert dialog. My code:

public class AddingFavoriteDialog extends AlertDialog {
private OnAddingFavoriteListener       onAddingFavoriteListener;
private Context context;
private GeocodingManager geocodingManager;
private FavoritesActivity favoritesActivity;

public AddingFavoriteDialog(Context context, OnAddingFavoriteListener onAddingFavoriteListener) {
 super(context, android.R.style.Theme_Dialog);

this.context = context;
this.onAddingFavoriteListener = onAddingFavoriteListener;
this.geocodingManager = new GeocodingManager(context);
this.favoritesActivity = (FavoritesActivity) context;
}

@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);

 setContentView(R.layout.adding_favorite_dialog2);

 setTitle("MYTITLE");

 setIcon(R.drawable.star_gold);
 }

What am i doing wrong? I also tried to set it by calling super.setTitle("MYTITLE"); in onCreate() as well as in the constructor.

EDIT: Even setButton(BUTTON_POSITIVE, context.getString(R.string.button_value_OK), new OnClickListener() {...} seems not to work.

Answer 1

Use setView instead of setContentView , because setContentView replaces everything in the AlertDialog , including the default title bar and icon (and buttons etc.). Instead, setView only replaces the middle part (the message, if you will).

Use LayoutInflater if you need to.

Answer 2

扩展对话框而不是AlertDialog将解决此问题。
