Android Service 类似于Windows 的 Windows Service，由于Windows 服务的作用大家都很熟悉了，这里就不介绍了。今天写了一个简单的例子，介绍Android Service 的使用方式。Android 界面有两个按钮，一个是启动服务，一个是停止服务。
ServiceActivity
package com.example.androidexample;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class ServiceActivity extends Activity {
private Button btnStartService;
private Button btnStopService;
private Intent intent;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
super.setContentView(R.layout.activity_service);
intent = new Intent();
intent.setAction("My_Action");
btnStartService = (Button)super.findViewById(R.id.btnStartService);
btnStopService = (Button)super.findViewById(R.id.btnStopService);
btnStartService.setOnClickListener(startServiceListener);
btnStopService.setOnClickListener(stopServiceListener);
}
OnClickListener startServiceListener = new OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
startService(intent);
}
};
OnClickListener stopServiceListener = new OnClickListener(){
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
stopService(intent);
}
};
}
FirstService
package com.example.business;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
import com.example.androidexample.*;
public class FirstService extends Service {
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
System.out.println("Service is created.");
//Toast.makeText(new ServiceActivity(), "Service is created", Toast.LENGTH_LONG).show();
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
System.out.println("Service is destoryed.");
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
System.out.println("Service is started.");
// TODO Auto-generated method stub
return super.onStartCommand(intent, flags, startId);
}
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
}
布局文件 activity_service.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<Button
android:id="@+id/btnStartService"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/StartService"/>
<Button
android:id="@+id/btnStopService"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/StopService"/>
</LinearLayout>
运行效果
