package cn.itcast.web;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.View;import android.webkit.WebSettings;import android.webkit.WebView;public class DemoActivity extends Activity {private WebView webView;@Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        webView = (WebView) this.findViewById(R.id.webview);        //相当于创建了一个浏览器                                 WebSettings settings = webView.getSettings(); // 得到浏览器的设置        settings.setJavaScriptEnabled(true);        webView.addJavascriptInterface(new Object(){        public void callPhone(){        System.out.println("callphone");        Intent intent = new Intent();        intent.setAction(Intent.ACTION_CALL);        intent.setData(Uri.parse("tel:1351234567"));        startActivity(intent);        }                }, "demo");        String  url = getResources().getString(R.string.serverurl);        webView.loadUrl(url);    }public void calljavascript(View view){webView.loadUrl("javascript:fillContent()");}}

<?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" ><Button        android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:text="调用javascript"    android:onClick="calljavascript"    >    </Button><WebView     android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:id="@+id/webview"    /></LinearLayout>

服务器端代码:

<html >   <head><meta http-equiv="Content-Type" content="text/html;charset=utf-8" /></head>    <script>          function fillContent(){               document.getElementById("content").innerHTML =                     "java调用javascript哈哈,这些话事javascript搞出来的";           }         </script>     <body>       <p><a onClick="window.demo.callPhone()" href="">打电话</a></p>       <p id="content"></p>       <p>java和javascript相互调用</p>   </body>   </html>
