for other questions I've pulled the most effective ways to do this are:

finish();startActivity(getIntent());

OR

// Refresh main activity upon close of dialog box
Intent refresh =new Intent(this, ActivityWeAreIn.class);
startActivity(refresh);

Note: this also works with Activity objects or from Fragments using getActivity()

You can do this by yourself through a Handler on which you call postDelayed(..)

http://developer.android.com/reference/android/os/Handler.html#postDelayed(java.lang.Runnable, long)

Put this in your class:

private final Handler handler = new Handler();

make a function called: doTheAutoRefresh() that does:

private void doTheAutoRefresh() {
    handler.postDelayed(new Runnable() {
             @Override
             public void run() {
                 doRefreshingStuff(); // this is where you put your refresh code
                 doTheAutoRefresh();                
             }
         }, 1000);
}

Call this function in your onCreate.

NOTE: this is the basic approach. consider stopping this after onPause has been called and to resume it after onResume. Look at the handler class to see how to remove.
