前提：使用可以联网的模拟器或者手机调试

一，更改xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, MainActivity"
/>
<WebView
android:id="@+id/myWebView1"
android:layout_height="330px"
android:layout_width="300px"
android:layout_x="7px"
android:layout_y="90px"
android:focusable="false"
/>

</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="tianshuai.webView"
android:versionCode="1"
android:versionName="1.0">
<application android:label="@string/app_name" >
<activity android:name="MainActivity"
android:label="@string/app_name">

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.INTERNET"/>  --允许程序联网
</manifest>
