反正有没有在Android的本机代码中获取移动设备的数据连接状态?

无论如何在Android的本机代码中获取移动设备的数据连接状态?我知道我们可以用Java中的ConnectivityManager来完成它。

Android的原生代码中有类似的东西吗?当他们从Gingerbread开始支持本地活动时,他们也会为连接管理员提供支持。

如果有人知道,请告诉我。我尝试了但是我没有在本地有类似的东西。我现在唯一的想法是在JAVA中使用连接管理器实现一个类,并从本机调用这些函数。

谢谢&问候,

检查一下:

设置你的听众:

    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)
        { }
    } 

};

然后你必须注册听众:

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);
}

然后现在你可以获得数据状态:

    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;
}

你还需要在清单中获得许可:

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