我怎樣才能整合我的android錄音機代碼，以顯示用戶的當前位置？

Question

爲了製作簡單的錄音機應用程序，我通讀了大量的代碼。它工作得很好，而且非常簡單，但現在我想將它與一些額外的功能集成在一起，使用簡單的實用程序顯示用戶的當前位置，如文本框。我非常瞭解Java編程，但我仍然在學習Android，所以我在如何做事方面有些不穩定。我已閱讀了許多教程和示例，我也嘗試了許多不同的方法，但似乎沒有任何工作。我正在開發使用Eclipse和Android SDK的版本8。我也有一個Android手機來測試已證明是非常有用的應用程序。

這是我的代碼，這個工程和它的一個應用程序，作爲一個錄音機。任何幫助將不勝感激：

您應通過在Android開發者文檔
