绑定本地服务

布局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <TextView        android:id="@+id/textView1"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_marginTop="22dp"        android:text="绑定服务" />    <ToggleButton        android:id="@+id/toggleButton"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@+id/textView1"        android:layout_centerHorizontal="true"        android:layout_marginTop="22dp"        android:textOff="开启服务"        android:textOn="关闭服务" />    <Button        android:id="@+id/button"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@+id/toggleButton"        android:layout_centerHorizontal="true"        android:layout_marginTop="22dp"        android:text="开启服务中的方法" /></RelativeLayout>

服务

package com.example.localbinde;import android.app.Service;import android.content.Context;import android.content.Intent;import android.os.Binder;import android.os.IBinder;import android.widget.Toast;public class MyLocalService extends Service {Context context;@Overridepublic void onCreate() {context = this;super.onCreate();}@Overridepublic void onDestroy() {super.onDestroy();}@Overridepublic IBinder onBind(Intent intent) {return new MyBinder();}class MyBinder extends Binder implements MyInterface {public void method() {System.out.println("");Toast.makeText(context, "服务里的方法", 0).show();}}}

服务提供的方法接口

package com.example.localbinde;public interface MyInterface {void method();}

绑定远程服务AIDL

参考绑定本地服务的流程
远程服务应用利用隐式意图激活配置action。
远程服务的接口文件 .java ---> .aidl文件删除public 访问修饰符
MyBinder extends IAliPay.Stub
复制aidl文件到调用远程服务的项目中，注意包名跟远程服务中的保持一致
本地服务获取到接口对象后，IAliPay.Stub.asInterface(service);得到远程服务的代理对象

远程服务

package com.example.remoteService;import android.app.Service;import android.content.Intent;import android.os.IBinder;public class MyRemoteService extends Service {@Overridepublic IBinder onBind(Intent intent) {return new MyBinder();}class MyBinder extends MyInterface.Stub {public boolean method(int num) {System.out.println("服务里的方法");if (num == 0) {return true;} else {return false;}}}}

aidl文件

package com.example.remoteService; interface MyInterface {boolean method(int num);}
