案例：HttpUrlConnection 加载百度页面

主要布局文件 activity_http_network_main.xml：

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".HttpNewworkMainActivity" >        <WebView        android:id="@+id/webview1"        android:layout_width="match_parent"        android:layout_height="match_parent" /></RelativeLayout>
