to reload the activity, complete or finish the activity first and then call the intent.

finish();
startActivity(getIntent());

or follow this post, https://stackoverflow.com/a/6283098/6780216

On the Button click execute following code:

Intent intent = new Intent(context,MainActivity.class);
context.startActivity(intent);

Maybe you can post some code. According to my current understanding I have edited the answer. – Naddy Dec 18 '13 at 12:17
getAplicactionContext(), finish() and startActivity() are undefined... this is ok in main class but not in alert dialog class. **public class changeColors extends Dialog implements android.view.View.OnClickListener{** – user3092292 Dec 18 '13 at 12:38
getActivity() is undefined – user3092292 Dec 18 '13 at 12:41
Why don't you post your class in your question?? Instead of letting me guess what you have done. – Naddy Dec 18 '13 at 12:42
@user3092292 Thanks for posting your code. On your button click execute the updated code. It should work now. – Naddy Dec 18 '13 at 18:09
