I'm not sure, that i understand right.

To update Layout information you can use findViewById(int). This is Method return View object. Then cast it to those real class. for examle:

TextView tv = (TextView) findViewById(R.id.TextView1);

To update this fields, use: tv.setText("Hello!");

There is no need, to "refresh page". You can use sockets and update fields when server replies (Using socket Events).
