Answer 1

您已忘記清單文件中的Internet權限。

<uses-permission android:name="android.permission.INTERNET" />

之后，您將獲得networkonmainthreadexception，因為您正在主線程中執行Web請求。
為此使用另一個AsyncTask或另一個線程。

Answer 2

您必須將Internet權限添加到您的manifiedt文件中：

<uses-permission android:name="android.permission.INTERNET" />

Android也不允許您在主線程中進行HTTP連接，有關更多信息，請查詢：

http://developer.android.com/reference/android/os/AsyncTask.html

Answer 3

你忘了也加

<uses-permission android:name="android.permission.INTERNET" />

在manifest.xml中。

但是之后，您將收到networkmainthreadexception，為避免這種情況，您需要使用AsyncTask或額外的線程 。 如果您在使用這些東西時遇到問題，請閱讀這篇文章 ，這可能會對您有所幫助。
