可以通过CTelephony类中的GetIndicator()来获得相关信息。

• 异步调用，我们可以通过调用CTelephony::EGetIndicatorCancel来取消它

所需链接库:

LIBRARY Etel3rdParty.lib and euser.lib

class CClientApp : public CActive
    {
 
private:
    CTelephony* iTelephony;
    CTelephony::TIndicatorV1 iIndicatorV1;
    CTelephony::TIndicatorV1Pckg iIndicatorV1Pckg;
public:
    CClientApp(CTelephony* aTelephony);
    void DetectCharger();
 
private:
    void RunL();
    void DoCancel();
   };
 
CClientApp::CClientApp(CTelephony* aTelephony)
    : CActive(EPriorityStandard),
      iTelephony(aTelephony),
      iIndicatorV1Pckg(iIndicatorV1)
    {
    //Constructor
 CActiveScheduler::Add(this);
    }
 
void CClientApp::DetectCharger()
    {
    iTelephony->GetIndicator(iStatus, iIndicatorV1Pckg);
    SetActive();
    }
 
void CClientApp::RunL()
    {
    if(iStatus==KErrNone)
       {
       if(iIndicatorV1.iCapabilities & CTelephony::KIndChargerConnected)
          {
          //We can detect when a charger is connected
          if(iIndicatorV1.iIndicator & CTelephony::KIndChargerConnected)
             {
               //Now, charger is connected
             }
          else
             {
               //Here, charger is not connected
             }
          }
       else
          {
             //Here, we do not know whether or not a charger is connected
          }
       }
    }
 
//To cancel this asynchronous call
void CClientApp::DoCancel()
    {
    iTelephony->CancelAsync(CTelephony::EGetIndicatorCancel);
    }
