Native+WebApp中Phonegap调用Android 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：

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的插件配置类phonegap.xml：

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

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

 

androidActivity.js

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());
