刚开始接触AIDL，想学着使用它，但是网上搜了一圈发现全都是Eclipise教程，很少有Android studio 的教程，这篇博客将为大家介绍如何使用Android studio来使用aidl,.
一、AIDL创建的步骤
１、创建.aidl文件，可以在里面写自己的方法；
2、编译生成java interface 文件；
3、创建aidl service的服务类，重写前面提到的方法；
4、在Activity中启动Service 调用AIDL；
二、详细步骤
1、创建.adil文件
如图所示，android studio提供了简便的创建方法：
我们创建一个名为MyService的aidl文件：源代码如下：
interface MyService {
/**
* Demonstrates some basic types that you can use as parameters
* and return values in AIDL.
*/
void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat,
double aDouble, String aString);
void Download();
}
2、编译生成java interface
但是此时并没有AIDL的java文件产生，其实android studio也是带有自动生成的，只不过需要确认一些信息后才能生成。此时，我们可以在目录 build-->generated-->source-->aidl-->test-->debug下面发现还没有任何文件
如果一致，则编译
编译后我们再看，debug，就会发现多了一个java文件。
3、创建MyService的服务类
package com.example.terry.studyaidl;
import android.app.Notification;
import android.app.Notification.Builder;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
/**
* Created by Terry on 2016/4/18.
*/
public class MainService extends Service {
boolean flag;
private final static String TAG = "MainService";
int i=1;
@Override
public void onDestroy() {
super.onDestroy();
Log.e(TAG, "+++++=MainSeverice destory++++");
flag = false;
}
@Override
public IBinder onBind(Intent intent) {
Bundle bundle = intent.getExtras();
flag = bundle.getBoolean("flag");
System.out.println(flag);
return ms;
}
@Override
public int onStartCommand(Intent intent,int flags, int startId) {
return super.onStartCommand(intent,flags,startId);
}
@Override
public void onCreate() {
flag = true;
NotificationManager notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
Builder builder = new Notification.Builder(MainService.this);
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pi = PendingIntent.getActivity(this, 0, intent, 0);
Log.e(TAG, "++++++MainService Create++++++");
builder.setContentIntent(pi)
.setContentText("您有一条新消息！")
.setContentTitle("有通知到来")
.setSmallIcon(R.mipmap.ic_launcher)
.setWhen(System.currentTimeMillis())
.setAutoCancel(true);
Notification notification = builder.getNotification();
notificationManager.notify(i++,notification);
}
MyService.Stub ms = new MyService.Stub() {
@Override
public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException {
}
@Override
public void Download() throws RemoteException {
Log.d(TAG,"***++++start download+++***");
new Thread(new Runnable() {
int i = 0;
@Override
public void run() {
//未达到线程条件，会一直在后台运行，就算服务已经关闭
while (flag) {
try {
i++;
Log.e("i的值是：", String.valueOf(i));
System.out.println("i的值是" + i);
Thread.sleep(1000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
Log.e("推出服务i的值是：", String.valueOf(i));
}
}).start();
}
};
}
4、在Activity中调用Service
package com.example.terry.studyaidl;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.IBinder;
import android.os.RemoteException;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
private MyService myService;
private Intent binderIntent;
private final static boolean create_flag =true;
private final static boolean destory_flag = false;
private String TAG = "MainActivity";
private Button button;
private ServiceConnection sc = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder service) {
myService =MyService.Stub.asInterface(service);
try{
//通过AIDL调用Service
Log.d(TAG,"++++start download+++");
myService.Download();
Log.d(TAG, "++++start%%% download+++");
}catch (RemoteException e)
{
e.printStackTrace();
}
}
@Override
public void onServiceDisconnected(ComponentName name) {
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
Log.d(TAG, "+++++++MainActivity start++++");
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//开启服务
Log.e(TAG, "%%%%%%%%%%%");
button = (Button) findViewById(R.id.start);
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//Intent i = new Intent(MainActivity.this, MainService.class);
//startService(i);
Log.e(TAG, "%%%%#####%%%%%%%");
//链接远程Service和Activity
binderIntent = new Intent(MainActivity.this, MainService.class);
Bundle bundle = new Bundle();
bundle.putBoolean("flag", create_flag);
binderIntent.putExtras(bundle);
bindService(binderIntent, sc, BIND_AUTO_CREATE);
Log.e(TAG, "%%%%#####%%%%%@@@@@%%");
}
});
}
@Override
protected void onDestroy(){
super.onDestroy();
Log.d(TAG,"+++Activity onDestory()+++++");
boolean flag = false;
//暂停服务
//Intent intent = new Intent(this,MainService.class);
///stopService(intent);
//断开连接
unbindService(sc);
}
}
对了不要忘记在AndroidMainifest.xml文件中注册Service
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.terry.studyaidl">
<permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>
<uses-permission android:name="android.permission.GET_TASKS" />
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service android:name=".MainService" android:process=":remote">
</service>
</application>
</manifest>
