2. 客户端实现:
(1)目录结构,如下图:
(2)将服务器端的IAIDLService.aidl,Person.aidl和Person.java文件拷贝到本工程中,如上图所示:
(3)res/layout/main.xml实现:
Java代码:
- <?xml version="1.0" encoding="utf-8"?>
- <LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
- android:orientation = "vertical"
- android:layout_width = "fill_parent"
- android:layout_height = "fill_parent"
- >
- <TextView
- android:id = "@+id/name"
- android:layout_width = "wrap_content"
- android:layout_height = "wrap_content"
- />
- <Button
- android:id = "@+id/connection"
- android:layout_width = "wrap_content"
- android:layout_height = "wrap_content"
- android:text = "连接"
- />
- <Button
- android:id = "@+id/message"
- android:layout_width = "wrap_content"
- android:layout_height = "wrap_content"
- android:enabled = "false"
- android:text = "信息"
- />
- <Button
- android:id = "@+id/person"
- android:layout_width = "wrap_content"
- android:layout_height = "wrap_content"
- android:enabled = "false"
- android:text = "人"
- />
- </LinearLayout>
(4)主Activity实现,从服务器端获取数据在客户端显示:
Java代码:
- package eoe.demo;
- import android.app.Activity;
- import android.content.ComponentName;
- import android.content.Intent;
- import android.content.ServiceConnection;
- import android.os.Bundle;
- import android.os.IBinder;
- import android.os.RemoteException;
- import android.view.View;
- import android.view.View.OnClickListener;
- import android.widget.Button;
- import android.widget.TextView;
- import com.focus.aidl.IAIDLService;
- import com.focus.aidl.Person;
- public class AIDLClientAcitivty extends Activity {
- private IAIDLService mAIDLService;
- private TextView mName;
- private Button mMessage;
- private Button mPerson;
- /**
- * 第一步,创建ServiceConnection对象,在onServiceConnected()方法中获取IAIDLService实现。
- */
- private ServiceConnection mServiceConnection = new ServiceConnection() {
- public void onServiceConnected(ComponentName name, IBinder service) {
- mAIDLService = IAIDLService.Stub.asInterface(service);
- mMessage.setEnabled(true);
- mPerson.setEnabled(true);
- }
- public void onServiceDisconnected(ComponentName name) {
- mAIDLService = null;
- mMessage.setEnabled(false);
- mPerson.setEnabled(false);
- }
- };
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- mName = (TextView) findViewById(R.id.name);
- findViewById(R.id.connection).setOnClickListener(new OnClickListener() {
- public void onClick(View view) {
- /**
- * 第二步,单击"连接"按钮后用mServiceConnection去bind服务器端创建的Service。
- */
- Intent service = new Intent("com.focus.aidl.IAIDLService");
- bindService(service, mServiceConnection, BIND_AUTO_CREATE);
- }
- });
- mMessage = (Button) findViewById(R.id.message);
- mMessage.setOnClickListener(new OnClickListener() {
- public void onClick(View view) {
-
- /**
- * 第三步,从服务器端获取字符串。
- */
- try {
- mName.setText(mAIDLService.getName());
- } catch (RemoteException e) {
- e.printStackTrace();
- }
- }
- });
- mPerson = (Button) findViewById(R.id.person);
- mPerson.setOnClickListener(new OnClickListener() {
- public void onClick(View view) {
- /**
- * 第四步,从服务器端获取Person对象。
- */
- try {
- Person mPerson = mAIDLService.getPerson();
- mName.setText("姓名:" + mPerson.getName() + ", 年龄:" + mPerson.getAge());
- } catch (RemoteException e) {
- e.printStackTrace();
- }
- }
- });
- }
- }
