android中启动服务

在Activity中

 

package cn.edu.servicetest;

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 ServiceTestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        Button btn=(Button)this.findViewById(R.id.btn);
        btn.setOnClickListener(new OnClickListener(){

			@Override
			public void onClick(View arg0) {
				// TODO Auto-generated method stub
				Intent intent=new Intent();
				intent.setClass(ServiceTestActivity.this, MyService.class);
				ServiceTestActivity.this.startService(intent);
			}
        	
        });
    }
}

 二、继承Service

 

package cn.edu.servicetest;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;

public class MyService extends Service{

	@Override
	public int onStartCommand(Intent intent, int flags, int startId) {
		// TODO Auto-generated method stub
		System.out.println("service Begin");
		return super.onStartCommand(intent, flags, startId);
	}

	@Override
	public IBinder onBind(Intent arg0) {
		// TODO Auto-generated method stub
		return null;
	}

}

 

在AndroidManifest.xml中增加如下配置信息

 

<service android:name="cn.edu.servicetest.MyService">
	</service>
