WebView Study Notes

Can be easily understood as a component, as with Button edittext.

As an example:

Main function:

Package Com.example.webviewdemo;import Android.app.activity;import Android.os.bundle;import Android.view.View; Import Android.view.view.onclicklistener;import Android.webkit.webview;import Android.webkit.webviewclient;import Android.widget.button;import Android.widget.edittext;public class Mainactivity extends Activity {private Button start; Private EditText address;p rivate WebView web = null; @Overrideprotected void OnCreate (Bundle savedinstancestate) {SUPER.O Ncreate (savedinstancestate); Setcontentview (r.layout.activity_main); this.web = (WebView) Findviewbyid (R.id.webview ); this.address = (EditText) Findviewbyid (r.id.address); This.start = (Button) Findviewbyid (R.id.start); This.start.setOnClickListener (New Onclicklistener () {@Overridepublic void OnClick (View v) {//TODO auto-generated Method stubstring str = Address.gettext (). toString (); Web.setwebviewclient (new Webviewclient ()); Web.getsettings ().  Setjavascriptenabled (TRUE); Allow JavaScript script to run Web.loadurl ("http://" +STR);}});}}

Layout:

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android"    xmlns:tools= "http// Schemas.android.com/tools "    android:layout_width=" match_parent "    android:orientation=" vertical    " android:layout_height= "Match_parent"    tools:context= "com.example.webviewdemo.MainActivity" >    < EditText         android:id= "@+id/address"        android:layout_width= "fill_parent"        android:hint= "Enter URL here"        android:layout_height= "Wrap_content"/>        <button         android:id= "@+id/start"        android:layout_ Width= "Wrap_content"        android:layout_height= "wrap_content"        android:text= "open page"/>        <webview         android:id= "@+id/webview"        android:layout_width= "fill_parent"        android:layout_height= "Wrap_ Content "        android:layout_margintop=" 10DP "        android:layout_weight=" 1 "/>        </LinearLayout>
