<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:orientation="vertical" >
<include layout="@layout/activity_school_title" />
<WebView
android:id="@+id/id_webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="none" />
</LinearLayout> |
效果图：PS：可以缩放，并且支持双击Max，支持脚本。
