Native+WebApp中Phonegap调用Android Activity

          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;
/**

 */
public class AndroidActivityPlugin  extends Plugin{
	 
	private Object synObj = new Object();
	@Override
	public PluginResult execute(String action, JSONArray data, String callbackID) {
		// TODO Auto-generated method stub
		if(action.equals("startActivity")){
			PluginResult result = null;
			
			try {		
				PluginResult.Status status = PluginResult.Status.OK;
				if(action.equals("startActivity")){ 
					Log.e("test", "test plugin js -> java~~~~"+data.getString(0)); 
					Log.e("test", "test plugin js -> java~~~~"); 				
					result = new PluginResult(status, data.getString(0));	
					Message msg=new Message();
					msg.what=1;
					Log.e("参数信息：", data.toString());
					msg.obj=data.getString(0);
					handler.sendMessage(msg);
					sleep();
				}
			} catch (Exception e) {
			}
			return result;
		}else {
            return new PluginResult(PluginResult.Status.INVALID_ACTION);
		}
	
	}
	private Handler handler = new Handler() {
		public void handleMessage(Message msg) {
			if (msg == null) {
				return;
			}
			switch (msg.what) {
			case 1:
				String className=msg.obj.toString();
				try {
					Class activityClass = Class.forName(className);
					Intent intent = new Intent(ctx.getBaseContext(), activityClass);//你想去的activity(exp:Temp)
					ctx.startActivityForResult(AndroidActivityPlugin.this, intent, 1);
				} catch (ClassNotFoundException e) {
					Log.e("Why", "错误原因："+className);
					e.printStackTrace();
				}
				break;
			}
		};
	};
	
	@Override
	public void onActivityResult(int requestCode, int resultCode, Intent intent) {
		// TODO Auto-generated method stub	
		if(requestCode==1){
			if(resultCode == Activity.RESULT_CANCELED){
				//返回时调用
				Log.e("test", "result plugin -> java~~~~"); 
				Log.e("test", "result plugin -> java~~~~"); 
				weakup();
			}
		}else{
			super.onActivityResult(requestCode, resultCode, intent);
		}
	}
	
	
	private void sleep()
    {
        try
        {
            synchronized(synObj)
            {
                synObj.wait();
            }
        }
        catch (InterruptedException e)
        {
            e.printStackTrace();
        }
    }
	
	private void weakup()
    {
        synchronized(synObj)
        {
            synObj.notify();
        }
    }
	
}

 

 

 

phonegap启动类：

package com.easyway.etrip;

import android.os.Bundle;

import com.phonegap.DroidGap;
/**
 * phonegap启动类
 * 
 * @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 PhonegapAndroidActivityActivity extends DroidGap  {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
    	  super.onCreate(savedInstanceState);
          super.loadUrl("file:///android_asset/www/index.html");
    }
}

 

Android的Activity类：

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：

   <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());
});
