安卓使用Webview来加载和显示网页内容，首先在layout文件中定义Webview
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" 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" app:layout_behavior="@string/appbar_scrolling_view_behavior" tools:context="cn.com.buynow.jspot.MainActivity" tools:showIn="@layout/app_bar_main"> <WebView android:id="@+id/webView" android:layout_width="match_parent" android:layout_height="match_parent"></WebView> </RelativeLayout>
