android进程间传递大量数据,Android AIDL进程间双向传递数据

AIDL 全称 Android Interface Definition Language(AndRoid 接口定义语 言)，参数可以传递基本数据类型、String和Bundle

AIDL:双向传递

Service：

1.interface FirstAIDL{

String getName();

void setUser(String name, int age, char sex);

}

==>Rebuild

2.public class AIDLService extends Service {

private FirstAIDL.Stub stub = new FirstAIDL.Stub() {

...    //    get、set

};

public IBinder onBind(Intent intent) {    return stub;    }

}

注册Service：

Client:

1.project拷贝Service aidl包    ==>Rebuild

2.MainActivity——>onCreate(){

//通过服务的隐式意图跳转方式开启服务

Intent intent = new Intent("service的action名");

intent.setPackage("service应用的包名");

bindService(intent, new MyConnection(),BIND_AUTO_CREATE);

}

class MyConnection implements ServiceConnection {

public void onServiceConnected(ComponentName name, IBinder service) {

FirstAIDL firstAidl = FirstAIDL.Stub.asInterface(service);

try {

String username = firstAidl.getName();

firstAidl.setUser("小米"， 18， 'm');

} catch(...) {}

}

}
