android中AIDL创建例子.docxVIP

一、创建AIDL文件ackage .android123;引入声明import .android123.IAtmService;// 声明一个接口，这里演示的是银行ATM程序interface IBankAccountService {int getAccountBalance(); //返回整数，无参数void setOwnerNames(in ListString names); //不返回，包含一个传入List参数BankAccount createAccount(in String name, int startingDeposit, in IAtmService atmService); //返回一个自定义类型int getCustomerList(in String branch, out String[] customerList); //返回整形，输入一个分支，输出一个客户列表}二、实现一个接口//显示的提供一个导出接口，为客户端提供绑定。public class RemoteService extends Service { @Override public IBinder onBind(Intent intent) { if (IRemoteService.class.getName().equals(intent.getAction())) { return mBinder; } if (ISecondary.class.getName().equals(intent.getAction())) { return mSecondaryBinder; } return null; } //第一个接口 private final IRemoteService.Stub mBinder = new IRemoteService.Stub() { public void registerCallback(IRemoteServiceCallback cb) { if (cb != null) mCallbacks.register(cb); } public void unregisterCallback(IRemoteServiceCallback cb) { if (cb != null) mCallbacks.unregister(cb); } };//第二个接口 private final ISecondary.Stub mSecondaryBinder = new ISecondary.Stub() { public int getPid() { return Process.myPid(); } public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) { } };}三、客户端交互/**通过Android.os提供的Parcelable类型来传递数据，通常我们使用Eclipse+ADT插件来完成，在Eclipse中在Package Explorer view视图上单击鼠标右键，选择Create Aidl preprocess file for Parcelable classes(创建aidl预编译文件)，最终我们创建一个名为android123.aidl文件*/import android.os.Parcel;import android.os.Parcelable;public final class Rect implements Parcelable {public int left;public int top;public int right;public int bottom;public static final Parcelable.CreatorRect CREATOR = new Parcelable.CreatorRect() {public Rect createFromParcel(Parcel in) {return new Rect(in);}public Rect[] newArray(int size) {return new Rect[size];
