android，使用httpget返回xml數據

我是android新手，對代碼的理解非常有限。我正試圖從互聯網上的api返回xml數據。我已經閱讀了幾篇關於此的文章，但沒有一篇似乎能夠工作，並且它們對代碼的解釋很少，所以我無法對它進行太多的修改。android，使用httpget返回xml數據

任何人都可以請解釋我哪裏錯了，並給我一點指導什麼需要改變？

乾杯傢伙

你得到的總響應確保您的應用程序請求互聯網權限

3）要做到這一點，最簡單的方法是什麼？ log.v（「testest」，總計）;檢查它是否得到api響應或不響應？ –

兩件事情：

1）請使用一個單獨的線程做你的HTTP的獲取。請參閱： http://developer.android.com/reference/android/os/AsyncTask.html

2）請使用一個URLConnection

URLConnection conn = new URL("http://api.inapub.co.uk/venues/postcode [etc...]").OpenConnection();
