获取和判断正在运行的服务

/* 以循环及baseActivity方式取得任务名称与ID */

//获取服务

--------------String serviceinfo;
String serviceClassName;//需要判断服务的名称

ActivityManager am=(ActivityManager)this.getSystemService(ACTIVITY_SERVICE);


//获取后台运行的服务，参数50代表获取的最大数，可以自定义

List<RunningServiceInfo> runninglist = am.getRunningServices(50);



//将获取到的服务名称赋值给字符串serviceinfo

for(RunningServiceInfo info :runninglist){

serviceinfo+=info.service.getClassName()+"...\n";

}

//for (int i = 0; i < runninglist.size(); i++) {
// serviceinfo+=list.get(i).service.getClassName()+"...\n";
// }

//判断服务是否运行
for(int i=0;i<runninglist.size();i++){

if(serviceClassName.equals(runninglist.get(i).service.getClassName())){

//serviceClassName服务正在运行
