【问题描述】：

我想显示服务状态，如果它正在运行或停止。我正在使用下面的代码，但它在开始服务之前显示“已停止”。当服务启动时，它显示“正在运行”。当它再次停止时，它只显示“正在运行”。我在设置 sharedPreference 状态时是否犯了任何错误。 在mainActivity中

  onCreate()
  
   checkServiceStatus() ;
  

  private void checkServiceStatus() 

    Toast.makeText(getApplicationContext(),"in enableControls", Toast.LENGTH_LONG).show();
    boolean isServiceRunning = AppSettings.getServiceRunning(this);     
    if (isServiceRunning)
    
        Toast.makeText(getApplicationContext(),"service running", Toast.LENGTH_LONG).show();    
     
    else 
       
        Toast.makeText(getApplicationContext(),"service stopped", Toast.LENGTH_LONG).show();        
    



  public class AppSettings 
  
 public static final String SERVICE_STATE = "isServiceRunning";
 public static boolean getServiceRunning(Context context)
         SharedPreferences pref = context.getSharedPreferences(GPSLOGGER_PREF_NAME, 0);

         return pref.getBoolean(SERVICE_STATE, false);
 

 public static void setServiceRunning(Context context, boolean isRunning)
         SharedPreferences pref = context.getSharedPreferences(GPSLOGGER_PREF_NAME, 0);
         SharedPreferences.Editor editor = pref.edit();

         editor.putBoolean(SERVICE_STATE, isRunning);
         editor.commit();

【参考方案1】：

public class Receiver extends BroadcastReceiver        
    @Override
    public void onReceive(Context context, Intent intent)     
        ActivityManager manager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
        for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) 
            if (YourService.class.getName().equals(service.service.getClassName())) 
                //your service is running
            
        
        //your service is not running
    

【参考方案2】：

 ActivityManager manager = (ActivityManager)context.   getSystemService(Context.ACTIVITY_SERVICE);//use context received in broadcastreceiver

for (RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE))
 

     if (MyService.class.getName().equals(service.service.getClassName())) 
                         //running 
        
    else
          //not running 
        

 

【参考方案3】：

 public static boolean CheckServiceConnectivity(Context mContext) 
     
        ConnectivityManager connec = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);

        if (connec.getNetworkInfo(0).getState() == NetworkInfo.State.CONNECTED
                || connec.getNetworkInfo(1).getState() == NetworkInfo.State.CONNECTED)
            return true;

        return false;

我猜这是为了检查互联网连接
