• 详细描述

电话呼叫信息API提供了检查电话呼叫状态的功能，如呼出，接听，铃声和挂接状态，以及电话呼叫类型，如数据呼叫，语音呼叫以及传真。

使用方法

我们可以找到打入电话的呼叫类型和状态。

示例代码

头文件

#include <ctsydomainpskeys.h> // new header for S60 3rd Edition, FP2
#include<e32property.h>

可以通过传递KPSUidCtsyCallInformation(电话呼叫处理PS UID)和KTelephonyCallState，或者KTelephonyCallType到RProperty的Get()方法来检测呼叫类型和状态，这是一个发布和订阅的用户端接

口，示例代码如下：

RProperty的KCTsyCallState及KCTsyCallType类型为EInt

void CCallStatusAppUi::GetTelephonyStateAndType()
  {
      TBuf<20> printInfo;
      TInt aVal;  
      RProperty iRP;
      iRP.Get(KPSUidCtsyCallInformation ,KCTsyCallState ,aVal);
      switch(aVal)
      {
      	case EPSCTsyCallStateUninitialized:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Status - Uninitialized:"),printInfo);
      	}
      	break;
      	case EPSCTsyCallStateNone:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Status - None:"),printInfo);
      	}  	
      	break;
      	case EPSCTsyCallStateAlerting:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Status - Alert:"),printInfo);
      	}
      	break;
      	case EPSCTsyCallStateRinging:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Status - Ringing:"),printInfo);
      	}
      	break;
      	case EPSCTsyCallStateDialling:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Status - Dialing:"),printInfo);
      	}
        ..............
        ..............
      }
 
      printInfo.Zero();
 
      iRP.Get(KPSUidCtsyCallInformation ,KCTsyCallType ,aVal);
      switch (aVal)
      {
      	case EPSCTsyCallTypeUninitialized:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Type - Uninitialized:"),printInfo);
      	}
      	break;
      	case EPSCTsyCallTypeNone:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Type - None:"),printInfo);
      	}
      	break;
      	case EPSCTsyCallTypeCSVoice:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Type - CSVoice:"),printInfo);
      	}
      	break;
      	case EPSCTsyCallTypeFax:
      	{
      	printInfo.AppendNum(aVal);
      	CEikonEnv::InfoWinL(_L("Call Type - Fax:"),printInfo);
      	}
        ..............
        ..............     	
      }
  }

枚举类型如下：

enum TPSCTsyCallState :

   EPSCTsyCallStateUninitialized,
   EPSCTsyCallStateNone,
   EPSCTsyCallStateAlerting,
   EPSCTsyCallStateRinging,
   EPSCTsyCallStateDialling,
   EPSCTsyCallStateAnswering,
   EPSCTsyCallStateDisconnecting,
   EPSCTsyCallStateConnected,
   EPSCTsyCallStateHold

enum TPSCTsyCallType:

   EPSCTsyCallTypeUninitialized,
   EPSCTsyCallTypeNone,
   EPSCTsyCallTypeCSVoice,
   EPSCTsyCallTypeFax,
   EPSCTsyCallTypeData,
   EPSCTsyCallTypeHSCSD,
   EPSCTsyCallTypeH324Multimedia,
   EPSCTsyCallTypeVoIP
