在android的本机代码中，是否仍然可以获取手机的数据连接状态？

在Android的本机代码中是否有获取手机数据连接状态的方法？我知道我们可以用Java中的ConnectionManager来实现这一点

Android的本地代码中有类似的东西吗？当他们从姜饼开始支持本地活动时，他们也为connectivity manager提供了支持

如果有人知道，请告诉我。我试过了，但在native中没有类似的东西。到目前为止，我唯一的想法是在JAVA中使用Connectivity Manager实现一个类，并从本机调用这些函数

谢谢和问候，
SSuman185检查以下内容：

设置您的侦听器：

    private static class MyPhoneStateListener extends PhoneStateListener{ 
    @Override 
    public void onSignalStrengthsChanged(SignalStrength signalStrength){ /* Do Stuff */
        }
        catch(Exception ex)
        {
        }
    } 

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
      switch (state) {
      case TelephonyManager.CALL_STATE_IDLE:
        stateString = "Idle";
        break;
      case TelephonyManager.CALL_STATE_OFFHOOK:
        stateString = "Off Hook";
        break;
      case TelephonyManager.CALL_STATE_RINGING:
        stateString = "Ringing " + incomingNumber;
        break;
      }
    }

    @Override 
    public void onCellLocationChanged(CellLocation location) { 
        try
        {
             super.onCellLocationChanged(location); 
        }
        catch(Exception ex)
        { }
    } 

public static void Init_DataRelatedStuff(Context ForeignContext)
{
    foreignContext = ForeignContext;
    m_psl = new MyPhoneStateListener();
    m_telephonyManager = (TelephonyManager)foreignContext.getSystemService(Context.TELEPHONY_SERVICE);
    m_telephonyManager.listen(m_psl, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
    m_telephonyManager.listen(m_psl, PhoneStateListener.LISTEN_CELL_LOCATION);
    m_telephonyManager.listen(m_psl, PhoneStateListener.LISTEN_CALL_STATE);
}

})

然后您必须注册侦听器：

    private static class MyPhoneStateListener extends PhoneStateListener{ 
    @Override 
    public void onSignalStrengthsChanged(SignalStrength signalStrength){ /* Do Stuff */
        }
        catch(Exception ex)
        {
        }
    } 

    @Override
    public void onCallStateChanged(int state, String incomingNumber) {
      switch (state) {
      case TelephonyManager.CALL_STATE_IDLE:
        stateString = "Idle";
        break;
      case TelephonyManager.CALL_STATE_OFFHOOK:
        stateString = "Off Hook";
        break;
      case TelephonyManager.CALL_STATE_RINGING:
        stateString = "Ringing " + incomingNumber;
        break;
      }
    }

    @Override 
    public void onCellLocationChanged(CellLocation location) { 
        try
        {
             super.onCellLocationChanged(location); 
        }
        catch(Exception ex)
        { }
    } 

public static void Init_DataRelatedStuff(Context ForeignContext)
{
    foreignContext = ForeignContext;
    m_psl = new MyPhoneStateListener();
    m_telephonyManager = (TelephonyManager)foreignContext.getSystemService(Context.TELEPHONY_SERVICE);
    m_telephonyManager.listen(m_psl, PhoneStateListener.LISTEN_SIGNAL_STRENGTHS);
    m_telephonyManager.listen(m_psl, PhoneStateListener.LISTEN_CELL_LOCATION);
    m_telephonyManager.listen(m_psl, PhoneStateListener.LISTEN_CALL_STATE);
}

现在您可以获取数据状态：

    public static String getDataState()
{
    int nType = m_telephonyManager.getDataState();
    String value = "UNKNOWN";
    switch(nType)
    {
    case 0://DATA_DISCONNECTED
        value = "DISCONNECTED";
        break;
    case 1://DATA_CONNECTING
        value = "CONNECTING";
        break;
    case 2://DATA_CONNECTED
        value = "CONNECTED";
        break;
    case 3://DATA_SUSPENDED
        value = "SUSPENDED";
        break;
    default:
        value = "UNKNOWN";
        break;
    }
    return value;
}

您还需要清单中的权限：

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
