傳遞數(shù)據(jù)

自定義類型 要實現(xiàn)parceable 接口
并定義同名的aidl文件 文件內(nèi)容parcealbe 類名

實現(xiàn)接口回調(diào)：

要實現(xiàn)接口 接口用aidl定義這樣才能執(zhí)行，在不同進程間的對象的hashcode是不樣的，因此正常是無法回調(diào)的
接口也用aidl MyLatLngListenerAidl.aidl

package com.p2.pa.amap.location;  
interface MyLatLngListenerAidl  
{  
    void receiverLatLng(double lat,double lon);  
}  

實現(xiàn)類

public class MyLatLngListener extends MyLatLngListenerAidl.Stub {  
    ActivityMain context;  
    private AMap map;  
  
    public MyLatLngListener(AMap map, ActivityMain activityMain) {  
        super();  
        this.map = map;  
        this.context = activityMain;  
    }  
    @Override  
    public void receiverLatLng(double lat, double lon) throws RemoteException {  
        System.out.println("MyLatLngListener receiverLatLng lat:" + lat  
                + ",lon:" + lon);  
        locationOk(new LatLng(lat, lon));  
    }  

服務(wù)調(diào)用，綁定連接成功后添加偵聽

class MyLocatonConnection implements ServiceConnection {  
  
  
    @Override  
    public void onServiceConnected(ComponentName arg0, IBinder arg1) {  
        printLog("onServiceConnected");  
        aidl=LocationServiceAidl.Stub.asInterface(arg1);  
        isBind = true;  
        try {  
            MyLatLngListener listener = new MyLatLngListener(aMap, ActivityMain.this);  
            printLog("MyLatLngListener:"+listener.hashCode());  
            aidl.addListener(listener);  
        } catch (RemoteException e) {  
            // TODO Auto-generated catch block  
            e.printStackTrace();  
        }  
  
    }

//android service一直再運行，通過bindService拿到service的代理，并將自己到回調(diào)對象注冊過去，就能實現(xiàn)調(diào)用service中的方法，和在service中調(diào)用本地activity到方//法。做到了進程間通信。
