布局文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical" >    <WebView        android:id="@+id/wv"        android:layout_width="fill_parent"        android:layout_height="fill_parent"/></LinearLayout>

主activity

package t4.mft;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.webkit.WebView;import android.webkit.WebViewClient;import android.widget.Button;public class T4Activity extends Activity {    /** Called when the activity is first created. */WebView wv;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                wv = (WebView)findViewById(R.id.wv);        wv.getSettings().setJavaScriptEnabled(true);        wv.setScrollBarStyle(0);        wv.loadUrl("file:///android_asset/sample.html");                //在webView 加载完后 执行js        wv.setWebViewClient(new WebViewClient()        {           @Override        public void onPageFinished(WebView view, String url){        super.onPageFinished(view, url);        wv.loadUrl("javascript:wave()");        }        });                    }}

判断一个 webview 是否加载完成的方法

mWebView.setWebViewClient(new WebViewClient(){                           @Override                        public void onPageFinished(WebView view, String url)                         {                                //开始                                super.onPageFinished(view, url);                        }                        @Override                        public void onPageStarted(WebView view, String url, Bitmap favicon)                         {                                //结束                                super.onPageStarted(view, url, favicon);                        }});

在webview 加载中设置背景颜色

webView.setBackgroundColor(Color.parseColor("#000000"));

设置滚动条不显示

    wv_yali.setHorizontalScrollBarEnabled(false);//水平不显示    wv_yali.setVerticalScrollBarEnabled(false); //垂直不显示

wb.setInitialScale(95);//缩放比例/// 得到焦点后不放大wb.getSettings().setSupportZoom( true ); //Modify thiswb.getSettings().setDefaultZoom(WebSettings.ZoomDensity.FAR);//Add this//\\\

让输入的键盘类型为数字或其他

<inputtype="number"/><inputtype="tel"/>

<input type="search" />

**不弹出默认浏览器在 WebView 中加载

WebView wv;@Overridepublic void onCreate(Bundle icicle) {    super.onCreate(icicle);    setContentView(R.layout.main);    wv = (WebView) findViewById(R.id.wv1);    wv.loadUrl("http://wangjun.easymorse.com/");    wv.setWebViewClient(new WebViewClientDemo());}private class WebViewClientDemo extends WebViewClient {    @Override    // 在WebView中而不是默认浏览器中显示页面    public boolean shouldOverrideUrlLoading(WebView view, String url) {        view.loadUrl(url);        return true;    }}
