How can I integrate my android voice recorder code to also display the user's current location?

Question

I read through a lot of code in order to make a simple voice recorder application. It works very well and it is pretty straight forward but now and I want to integrate it with some extra feature to display the user's current location using a simple utility, something like a text box. I understand java programming really well but I am still learning Android so I am a bit shaky on how to do things. I have read through many tutorials and examples, I have also tried many different approaches but nothing seems to work. I am developing for version 8 using Eclipse and Android SDK. I also have an android phone to test the app in which has proven to be very helpful.

Here is my code, this works and its an app that works as a voice recorder. Any help would be greatly appreciated:

import android.app.Activity;
import android.widget.LinearLayout;
import android.os.Bundle;
import android.os.Environment;
import android.view.ViewGroup;

You should start out by taking a look at the Android developer docs

http://developer.android.com/guide/topics/location/obtaining-user-location.html

If you want to display the current address, look into Geocoder:
