Android创建UI的新思路：用javascript与Activity进行交互.zip

package com.example; import java.util.Vector; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.os.Handler; import android.util.Log; import android.webkit.WebView; public class RIAExample extends Activity{ private WebView web; private Handler mHandler = new Handler(); //模拟号码簿 private Vector<Person> phonebook = new Vector<Person>(); /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); this.initContacts(); web = (WebView)this.findViewById(R.id.web); web.getSettings().setJavaScriptEnabled(true);//开启javascript设置，否则WebView不执行js脚本 web.addJavascriptInterface(this,"phonebook"); web.loadUrl("file:///android_asset/phonebook.html"); } /** * 该方法将在js脚本中，通过window.phonebook.getContacts()进行调用 * 返回的JavaArrayJSWrapper对象可以使得在js中访问Java数组 * @return */ public JavaArrayJSWrapper getContacts(){ System.out.println("fetching contacts data"); Person[] a = new Person[this.phonebook.size()]; a = this.phonebook.toArray(a); return new JavaArrayJSWrapper(a); } /** * 初始化电话号码簿 */ public void initContacts(){ Person p = new Person(); p.name = "Perter123"; p.phone_number = "123456789"; phonebook.add(p); p = new Person(); p.name = "English"; p.phone_number = "123456789"; phonebook.add(p); } /** * 通过window.phonebook.debugout来输出js调试信息。 * @param info */ public void debugout(String info){ Log.i("ss",info); System.out.println(info); } public void startActivity(){ Intent intent = new Intent(RIAExample.this,JsActivity.class); startActivity(intent); } }
