【android小知识】判断服务开启状态

判断服务开启状态：

public class RunningService extends Activity { 
        /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        //setContentView(R.layout.main); 
        TextView mTextView = new TextView(this); 
        ActivityManager mActivityManager =  
          (ActivityManager)getSystemService(ACTIVITY_SERVICE); 
         
        List<ActivityManager.RunningServiceInfo> mServiceList = 
mActivityManager.getRunningServices(30); 
        // 我要判断的服务名字，我在 launcher2 里加了一个音乐服务    
        final String musicClassName = "com .android.launcher2.MusicService";        
        boolean b = MusicServiceI sStart(mServiceList, musicClassName); 
      
        mTextView.setText("你要判断的服务状态为: " + b + "\n" + getServiceClassName(mServiceList)); 
        setContentView(mTextView); 
    } 
    // 通过Service的类名来判断是否启动某个服务 
    public static boolean MusicServiceIsStart(List<A ctivityManager.RunningServiceInfo> mServiceList,String 
className){ 
      
          for(int i = 0; i < mServiceList.size(); i ++){ 
       if(className.equals(mServiceList.get(i).service.getClassName())){ 
         return true; 
       } 
     } 
     return false; 
    } 
    // 获取所有启动的服务的类名 
    private String getServiceC lassName(List<ActivityManager.Runni ngServiceInfo> mServiceList){ 
     String res = "";

          for(int i = 0; i < mServiceList.size(); i ++){ 
       res+=mServiceList.get(i).service.getClassName()+ " \n"; 
     } 
      
     return res; 
    } 
} 

获取启动服务

public class RunningService extends Activity { 
        /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState); 
        //setContentView(R.layout.main); 
        TextView mTextView = new TextView(this); 
        ActivityManager mActivityManager =  
          (ActivityManager)getSystemService(ACTIVITY_SERVICE); 
         
        List<ActivityManager.RunningServiceInfo> mServiceList = 
mActivityManager.getRunningServices(30); 
        // 我要判断的服务名字，我在 launcher2 里加了一个音乐服务    
        final String musicClassName  = "com.android.launcher2.MusicService"; 
               
        boolean b = MusicServiceI sStart(mServiceList, musicClassName); 
      
        mTextView.setText("你要判断的服务状态为: " +b+"\n" + getServiceClassName(mServiceList)); 
        setContentView(mTextView); 
    } 
    // 通过Service的类名来判断是否启动某个服务 
    private  boolean  MusicServiceIsStart(List<ActivityManager.RunningServiceInfo> mServiceList,String 
className){ 
      
          for(int i = 0; i < mServiceList.size(); i ++){ 
       if(className.equals(mServiceList.get(i).service.getClassName())){ 
         return true; 
       }
