Native+WebApp中Phonegap调用Android Activity

转自：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;

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());
});
