Native+WebApp中Phonegap调用Android(安卓)Activity

摘自：http://topmanopensource.iteye.com/blog/1577717

在项目采用Native+Web方式开发，Android团队开发一个模块的代码，WebApp phonegap开发几个模块，需要将Android中的模块潜入到Phonegap开发的几个模块中。需要通过Phonegap调用Android 的Activity。

demo如下：

Phonegap插件类：

Java代码

package com.easyway.etrip.plugins;
import org.json.JSONArray;
import android.app.Activity;
import android.content.Intent;
import android.os.Handler;
import android.os.Message;
import android.util.Log;
import com.phonegap.api.Plugin;
import com.phonegap.api.PluginResult;

phonegap启动类：

Java代码

package com.easyway.etrip;
import android.os.Bundle;
import com.phonegap.DroidGap;
/**
* phonegap启动类

* @Title:

*/
publicclass PhonegapAndroidActivityActivity extends DroidGap {
/** Called when the activity is first created. */
@Override
publicvoid onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/index.html");
}
}

Android的Activity类：

Java代码

package com.easyway.etrip;
import android.app.Activity;
import android.os.Bundle;
/**
*
*
* @Title:
* @Description: 实现TODO
* @Copyright:Copyright (c) 2011

* @version 1.0
*/
publicclass ThirdAndroidActivity extends Activity {
/** Called when the activity is first created. */
@Override
publicvoid onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.main);
}
}

package com.easyway.etrip;import android.app.Activity;import android.os.Bundle;/** *  *  * @Title:  * @Description: 实现TODO * @Copyright:Copyright (c) 2011 * @Company:易程科技股份有限公司 * @Date:2012-7-5 * @author  longgangbai * @version 1.0 */public class ThirdAndroidActivity extends Activity {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        super.setContentView(R.layout.main);    }}

phonegap的插件配置类phonegap.xml：

Xml代码

<pluginname="AndroidActivity"value="com.easyway.etrip.plugins.AndroidActivityPlugin"/>

   <plugin name="AndroidActivity" value="com.easyway.etrip.plugins.AndroidActivityPlugin"/>

androidActivity.js

Js代码

var AndroidActivity=function(){};
AndroidActivity.prototype.startActivity = function(success, fail,parmas)
{
return PhoneGap.exec(
function(args){ success(args); },
function(args){ fail(args); },
'AndroidActivity', //java类
'startActivity', //action
[parmas] //params
);
};
PhoneGap.addConstructor(function() {
PhoneGap.addPlugin('androidActivity', new AndroidActivity());
});

var AndroidActivity=function(){}; AndroidActivity.prototype.startActivity = function(success, fail,parmas){     return PhoneGap.exec(             function(args){ success(args); },             function(args){ fail(args); },             'AndroidActivity', //java类             'startActivity', //action             [parmas] //params              ); };PhoneGap.addConstructor(function() {    PhoneGap.addPlugin('androidActivity', new AndroidActivity());});
