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：

Java代码

  10.  
  11. import com.phonegap.api.Plugin; 
  12. import com.phonegap.api.PluginResult;

phonegap的插件配置类phonegap.xml：

Xml代码 
  1. <pluginname="AndroidActivity"value="com.easyway.etrip.plugins.AndroidActivityPlugin"/>  
   <plugin name="AndroidActivity" value="com.easyway.etrip.plugins.AndroidActivityPlugin"/>

 

androidActivity.js

Js代码 
  1. var AndroidActivity=function(){};  
  2. AndroidActivity.prototype.startActivity = function(success, fail,parmas) 
  3. {  
  4.     return PhoneGap.exec(  
  5.             function(args){ success(args); },  
  6.             function(args){ fail(args); },  
  7.             'AndroidActivity', //java类  
  8.             'startActivity', //action  
  9.             [parmas] //params  
  10.              );  
  11. }; 
  12. PhoneGap.addConstructor(function() { 
  13.     PhoneGap.addPlugin('androidActivity', new AndroidActivity()); 
  14. });  
var AndroidActivity=function(){}; 
AndroidActivity.prototype.startActivity = function(success, fail,parmas)
{ 
    return PhoneGap.exec(
