android中在webView中显示网页，在网页中通过Js调用通讯录中的联系人信息，显示到webView中。
部分开发代码如下：
首先的Html的代码如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Frameset//EN">
<HTML>
<META http-equiv=Content-Type content="text/html; charset=utf-8"><LINK
href="css/style_cn.css" type=text/css rel=stylesheet>
<SCRIPT language=JavaScript>
function contactlist(jsons){
var table=document.getElementById("contactTable");//获得html中Table
var arr = eval(jsons);//将jsons字符串转换为json对象数组
for(var i=0;i < arr.length;i++){
var jsonObj = arr[i];
var tr = table.insertRow(table.rows.length);//添加tr
var td1 = tr.insertCell(0);//td
var td2 = tr.insertCell(1);
td2.align = "center";
var td3 = tr.insertCell(2);
td1.innerHTML = jsonObj.id;//设置每列对应的值
td2.innerHTML = jsonObj.name;
td3.innerHTML = "<a href=\"javascript:myjavascript.call(‘"+jsonObj.phone + "‘)\">" + jsonObj.phone + "</a>";
}
}
function getAllLinkMan(){
javascript:myjavascript.getAllLinkMan();
}
function getSimLinkMan(){
javascript:myjavascript.getSimLinkMan();
}
function getLinkMan(){
javascript:myjavascript.getPhoneLinkMan();
}
function getNext(){
javascript:myjavascript.getNext();
}
</SCRIPT>
<BODY onload="javascript:myjavascript.show()">
<table width="100%" border="0" cellspacing="0" id="contactTable">
<tr>
<td width="20%">编号</td>
<td width="center">name</td>
<td width="30%">phone</td>
</tr>
</table>
<input type="button" value="获取所有的联系人" onclick="getAllLinkMan();"/>
<input type="button" value="获取多个的联系人" onclick="getLinkMan();"/>
<input type="button" value="获取sim的联系人" onclick="getSimLinkMan();"/>
<input type="button" value="获取单个的联系人" />
<input type="button" value="下一个页面" onclick="getNext();"/>
</BODY>

MainActivity中的部分代码如下：
public class MainActivity extends Activity {
private String contactId, contactName;
private WebView webView;
private Handler handler = new Handler();
//自定义的弹出框类
SelectPicPopupWindow menuWindow;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_main);
init();
}
@SuppressLint("JavascriptInterface")
private void init() {
webView = (WebView)findViewById(R.id.myweb);
//重要：让webview支持javascript
webView.getSettings().setJavaScriptEnabled(true);
//重要：添加可以供html中可供javascript调用的接口类
webView.addJavascriptInterface(new MyJavaScript(this, handler), "myjavascript");
//加载index.html
webView.loadUrl("file:///android_asset/index.html");
}
public void btnClick(View v){
//实例化SelectPicPopupWindow
menuWindow = new SelectPicPopupWindow(MainActivity.this, itemsOnClick);
//显示窗口
menuWindow.showAtLocation(MainActivity.this.findViewById(R.id.main), Gravity.BOTTOM|Gravity.CENTER_HORIZONTAL, 0, 0); //设置layout在PopupWindow中显示的位置
}
//为弹出窗口实现监听类
private OnClickListener itemsOnClick = new OnClickListener(){
public void onClick(View v) {
menuWindow.dismiss();
switch (v.getId()) {
default:
break;
}
}
};
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
Log.d("TAG", "requestCode"+requestCode+"\t resultCode"+resultCode+"\t"+data);
Uri result = data.getData();
contactId = result.getLastPathSegment();
contactName = getPhoneContacts(contactId);
Toast.makeText(this, "contactName"+contactName, Toast.LENGTH_LONG).show();
}代码大概就是这样！本人页是初学者，不是很完善。要源码的联系我！
