Prevent the dialog from opening several times when activity resumes

Question

In my Android application, to ask the user if he wants to resume the current game, I show the dialog “Do you want to resume the current game? Yes - No” in the main game.

The fact is that if I resume various actions without responding to the dialogue, I get several dialogues on top of each other, which is clearly not my goal.

I could easily avoid this behavior with Boolean var, but I was wondering if the Dialog class had some kind of option that prevents duplication or something like that.

Answer 1

, :

Dialog myDialog = null;


public void showDialog() {
    if(myDialog == null) {
        /* show your dialog here... */
        myDialog = ...
    }
}


public void hideDialog() {
    if(myDialog != null) {
        /* hide your dialog here... */
        myDialog = null;
    }
}

Answer 6

AlertDialog DialogFragment, google. [ ] [1]

Dialog , . :

AlertDialog
, , , .

DatePickerDialog TimePickerDialog , .

These classes define the style and structure of your dialog, but you should use DialogFragment as a container for your dialog. The DialogFragment class provides all the controls necessary to create your dialog and control its appearance , instead of calling methods in the Dialog object.
