施用android中的AIDL让Service与Activity通信[转]

使用android中的AIDL让Service与Activity通信[转]

首先建立一个ICallback.aidl文件,作为Activity中的回调方法

view plaincopy to clipboardprint?

然后再建立一个IService.aidl用来在Activity中接收Service回调,以及在Service中onBind时返回的Binder
注意:aidl中import不能写com.xxx.*,要写全类的路径

view plaincopy to clipboardprint?

接下来是service:
MainService.java

view plaincopy to clipboardprint?

package com.zhang.test.service;
import android.app.Service;
import android.content.Intent;
import android.os.Handler;
import android.os.IBinder;
import android.os.Message;
import android.os.RemoteCallbackList;
import android.os.RemoteException;
import android.util.Log;
public class MainService extends Service {
private static final String TAG = "MainService";
private RemoteCallbackList<icallback> mCallbacks = new RemoteCallbackList<icallback>();
private IService.Stub mBinder = new IService.Stub() {
@Override
public void unregisterCallback(ICallback cb){
if(cb != null) {
mCallbacks.unregister(cb);
}
}
@Override
public void registerCallback(ICallback cb){
if(cb != null) {
mCallbacks.register(cb);
}
}
};
@Override
public IBinder onBind(Intent intent) {
Log.d(TAG, "onBind");
return mBinder;
}
@Override
public void onCreate() {
Log.d(TAG, "onCreate");
//这里不知道为什么,直接使用callback方法回调showResult
//mCallbacks.beginBroadcast()是0,需要用handler延迟1000毫秒
//也许是在activity中binService太耗时的原因?
mHandler.sendEmptyMessageDelayed(0, 1000);
super.onCreate();
}
@Override
public void onDestroy() {
mHandler.removeMessages(0);
mCallbacks.kill();
super.onDestroy();
}
private void callBack() {
int
