点击后效果：
代码：主方法：
package com.text.ac;import java.util.Calendar;import android.app.Activity;import android.app.AlarmManager;import android.app.Notification;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Context;import android.content.Intent;import android.os.Bundle;import android.os.SystemClock;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;/*** * @author Hardi**/public class TextActivity extends Activity {Button button;Button buttonstop;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);button = (Button)findViewById(R.id.button);buttonstop=(Button)findViewById(R.id.titlebutton);button.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Intent intent = new Intent();// 设置Action属性intent.setAction("com.text.ac.action.MY_SERVICE");// 启动该ServicestartService(intent);// startService(new Intent(ExTextActivity.this, MessageService.class));}});buttonstop.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {Intent intent = new Intent();// 设置Action属性intent.setAction("com.text.ac.action.MY_SERVICE");// 关闭该ServicestopService(intent);}});}}
写了一个服务：
