WebView的使用

webvIEw很簡單，和普通widget沒什麼區別，就是要在androidManifest.XML中加一句<uses-permission android:name="android.permission.INTERNET"></uses-permission>來獲取對互聯網訪問的權限。

本例結合上節的SlidingDrawer，打開後顯示百度首頁。默認下Javascript是關的，要用語句打開。

<?XML version="1.0" encoding="utf-8"?>
<FrameLayout android:id="@+id/FrameLayout01"
 android:layout_width="fill_parent" android:layout_height="fill_parent"
 XMLns:android="">

  android:handle="@+id/handle" android:content="@+id/content"
  android:layout_height="wrap_content" android:layout_width="wrap_content"

  <WebVIEw android:id="@+id/content" android:layout_width="fill_parent"
