Finish activity in dialog class

Question

In my MainActivity I call

 myDialog dialog = new myDialog(MainActivity.this);
 dialog.show();

myDialog is my own

Answer 1

Firstly in your dialog class pass the context of the caller activities say MainActivit.class context

Now first close the dialog

//so as to avoid the window leaks as on destroying the activity it's context would also get vanished.
    dialog.dismiss();

and then

((Activity) context).finish();
