AIDL是Android接口定義語言，它可以用于讓某個Service與多個應用程序組件之間進行跨進程通信，從而可以實現(xiàn)多個應用程序共享同一個Service的功能。
實現(xiàn)步驟
例：用 A程序去訪問 B程序的MyService.java服務
對應步驟詳細代碼：
MyAidlService.AIDL
interface MyAidlService { int add(int a, int b); }MyService.Java
public class MyService extends Service{ MyAidlService.Stub mBinder = new MyAidlService.Stub() { @Override public int add(int a, int b) throws RemoteException { return a + b; } }; @Override public IBinder onBind(Intent intent) { return mBinder; } @Override public void onCreate() { super.onCreate(); } @Override public void onDestroy() { super.onDestroy(); } @Override public int onStartCommand(Intent intent, int flags, int startId) { return super.onStartCommand(intent, flags, startId); } }3.添加action
<service android:name=".MyService"> <intent-filter> <action android:name="com.xyb.servicetest.MyAidlService"/> </intent-filter> </service>
4.拷貝AIDL文件夾
5.A訪問B的服務
Intent intent = new Intent("com.xyb.servicetest.MyAidlService"); bindService(intent, connection, BIND_AUTO_CREATE);private MyAidlService aidlService;
private ServiceConnection connection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { Log.d("onServiceConnected", "onServiceConnected"); aidlService = (MyAidlService) MyAidlService.Stub.asInterface(service); try { int sum = aidlService.add(10, 50);//對10和50相加 Log.d("onServiceConnected", sum + ""); } catch (RemoteException e) { e.printStackTrace(); } } @Override public void onServiceDisconnected(ComponentName name) { } };以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VEVB武林網(wǎng)。
