android之phonegap入门

利用phoneGap可以利用HTML开发安卓应用，是web app的一种，可以有效的提高开发效率，降低开发成本。

第一步：

开发环境配置以及基本操作请参考其它文档.

新增一个名为 phoneGap 的android项目,将主activity命名为:PhoneGapActivity.java

从下载好的 phonegap 找到 lib\android,(下载地址记不太清了,google callback-phonegap-0d1f305)

按照以下目录分别复制到android 项目

assets\www\phonegap-1.4.1.js

res\xml\phonegap.xml

res\xml\plugins.xml

libs\phonegap-1.4.1.jar

以上路径除了www外,其它都是必须路径,不能更改名字,没有文件夹就创建一个

第二步：创建完成后复制以下代码到AndroidManifest.xml ,这些代码为程序提供权限,当然我们现在用不了这么多权限,但是加进去总没错.

<supports-screens
 android:largeScreens="true"android:normalScreens="true"android:smallScreens="true"android:resizeable="true"android:anyDensity="true"/><uses-permission android:name="android.permission.CAMERA" /><uses-permission android:name="android.permission.VIBRATE" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_LOCATION_EXTRA_COMMANDS" /><uses-permission android:name="android.permission.READ_PHONE_STATE" /><uses-permission android:name="android.permission.INTERNET" /><uses-permission android:name="android.permission.RECEIVE_SMS" /><uses-permission android:name="android.permission.RECORD_AUDIO" /><uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" /><uses-permission android:name="android.permission.READ_CONTACTS" /><uses-permission android:name="android.permission.WRITE_CONTACTS" /><uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

修改MainActivity

添加完成后,找到我们的主activity PhoneGapActivity.java 找到onCreate方法,

替换setContentView(R.layout.main);super.loadUrl(“http://baidu.com“);或者super.loadUrl(“file:///android_asset/www/index.html”);

第四步：写index.html文件

其中包括要调用的方法，和调用成功之后返回的方法，分为成功方法与失败方法

<!DOCTYPE HTML>
<html><head><meta http-equiv="Content-type" name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no, width=device-width"><title></title><script type="text/javascript" charset="utf-8" src="phonegap-1.4.1.js"> </script><script type="text/javascript" charset="utf-8" src="test.js"> </script><script type="text/javascript">function test1(){alert("HelloWorld");navigator.hmCommen.test(successCallback,errorCallback,{});}function testlogin(name,age){//navigator.hmCommen.testLogin(successCallback,errorCallback,{});navigator.hmCommen.testLogin(successCallback,errorCallback,{"name":name,"age":age});}function successCallback(){alert("Success");}function errorCallback(){alert("failed");}function test2(){alert("hello world");}</script></head><body><h1>Hello World</h1><button type="button" onclick="test2()">Hello Worold</button><button type="button" onclick="test1()">call me</button><button type="button" onclick="testlogin('abc',12)">login test</button></body></html>

第五步：写js文件

/** PhoneGap is available under *either* the terms of the modified BSD license *or* the* MIT License (2008). See http://opensource.org/licenses/alphabetical for full text.** Copyright (c) 2005-2010, Nitobi Software Inc.* Copyright (c) 2010-2011, IBM Corporation*/if (!PhoneGap.hasResource("hmCommen")) {
PhoneGap.addResource("hmCommen");/*** This class contains information about the current network Connection.* @constructor*/
var HmCommen = function() {};/*** Get connection info** @param {Function} successCallback The function to call when the Connection data is available* @param {Function} errorCallback The function to call when there is an error getting the Connection data. (OPTIONAL)*/
HmCommen.prototype.test = function(successCallback, errorCallback,options) {// Get infoPhoneGap.exec(successCallback, errorCallback, "HM_service", "test", [options]);
};HmCommen.prototype.testLogin = function(successCallback, errorCallback,options) {// Get infoPhoneGap.exec(successCallback, errorCallback, "HM_service", "testLogin", [options]);
};PhoneGap.addConstructor(function() {if (typeof navigator.hmCommen === "undefined") {navigator.hmCommen = new HmCommen();}});
}

第六步：配置XML文件

在plungs.xml中添加

 <plugin name="HM_service" value="com.zj.phonegaptest.HMTest"/>

注意，第五步中对象必须与XML中配置的相同，value即为要调用的类，这样才知道要调用哪一个类

第七步：写实现类

package com.zj.phonegaptest;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;import android.widget.Toast;import com.phonegap.api.*;public class HMTest extends Plugin {@Overridepublic PluginResult execute(String arg0, JSONArray arg1, String arg2) {// TODO Auto-generated method stubJSONObject arg=arg1.optJSONObject(0);if(arg0.equalsIgnoreCase("test")){return doTest();}else if(arg0.equalsIgnoreCase("testLogin")){try {return testLogin(arg);} catch (JSONException e) {// TODO Auto-generated catch blocke.printStackTrace();}}return null;}private String name=null;private int age=0;PluginResult pluginResult=null;private PluginResult testLogin(JSONObject arg) throws JSONException{name=(String)arg.get("name");age=arg.getInt("age");if("abc".equals(name)){pluginResult=new PluginResult(PluginResult.Status.OK);}else{pluginResult=new PluginResult(PluginResult.Status.OK);}return pluginResult;}private PluginResult doTest(){pluginResult=new PluginResult(PluginResult.Status.OK);return pluginResult;}}
