客户端:

---

findViewById(R.id.in).setOnClickListener(v -> {

try {

Person in = new Person(“In”, “1”);

Log.d(TAG, "in1: " + in);

mService.setPersonIn(in);

Log.d(TAG, "in2: " + in);

} catch (RemoteException e) {

e.printStackTrace();

}

});

findViewById(R.id.out).setOnClickListener(v -> {

try {

Person out = new Person(“Out”, “1”);

Log.d(TAG, "out1: " + out);

mService.setPersonOut(out);

Log.d(TAG, "out2: " +

out);

} catch (RemoteException e) {

e.printStackTrace();

}

});

findViewById(R.id.inout).setOnClickListener(v -> {

try {

Person inOut = new Person(“InOut”, “1”);

Log.d(TAG, "inOut1: " + inOut);

mService.setPersonInOut(inOut);

Log.d(TAG, "inOut2: " + inOut);

} catch (RemoteException e) {

e.printStackTrace();

}

});

从代码可以知道，我们分别定义了使用 in ，out，inout 修饰的三个方法，然后在客户端分别调用了这三个方法，服务端则在收到对象后马上修改对象的属性。我们看一下运行起来的 Log，观察下数据流向。
