如何使用TrafficStats分别计算2G和3G中的数据使用情况？

当手机处于2G或3G模式时，如何混合/连接以下两个代码以分别计算TX和RX字节？
我有以下代码来识别手机何时连接到EDGE或似乎正常工作的UMTS网络，并在屏幕上显示Toast信息。

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        TelephonyManager telephonyManager = (TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
        PhoneStateListener ConnectionStateListener = new PhoneStateListener() {

            @Override
            public void onDataConnectionStateChanged(int state, int networkType) {
                super.onDataConnectionStateChanged(state, networkType);
                String sState = "";

                switch (networkType) {
                    case TelephonyManager.NETWORK_TYPE_EDGE:   sState = "EDGE (2G)";   break;
                    case TelephonyManager.NETWORK_TYPE_UMTS:   sState = "UMTS (3G)";   break;                    
                }
                Toast.makeText(getApplicationContext(), sState, Toast.LENGTH_SHORT).show();
            }
        };
        telephonyManager.listen(ConnectionStateListener,PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);
    }
}

从Tech Republic中的这个例子中，我得到这个代码来计算tx和rx字节。

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mStartRX = TrafficStats.getTotalRxBytes();
        mStartTX = TrafficStats.getTotalTxBytes();

        mHandler.postDelayed(mRunnable, 1000);
    }

    //This would be to update the bytes usage every second
    private final Runnable mRunnable = new Runnable() {
        public void run() {
        TextView RX = (TextView)findViewById(R.id.RX);
        TextView TX = (TextView)findViewById(R.id.TX);
        long rxBytes = TrafficStats.getTotalRxBytes()- mStartRX;
        RX.setText(Long.toString(rxBytes));

        long txBytes = TrafficStats.getTotalTxBytes()- mStartTX;
        TX.setText(Long.toString(txBytes));

        mHandler.postDelayed(mRunnable, 1000);
        }
        };
}

也许有人能帮我。提前感谢您的建议/帮助。

最佳答案：

如果我看错了你的问题，请纠正我。
您想分别计算2g和3g数据的tx和rx。
将必要的代码复制到单个活动。
取一个布尔值is3G并将其更改为onDataConnectionStateChanged
然后触发mRunnable

telephonyManager.listen(ConnectionStateListener,PhoneStateListener.LISTEN_DATA_CONNECTION_STATE);

mHandler.postDelayed(mRunnable, 1000);

分别测量内部2G和3G的rx/tx字节

 if(is3G) {
      rxBytes3G = TrafficStats.getTotalRxBytes() - mStartRX - rxBytes2G;
      txBytes3G = TrafficStats.getTotalTxBytes() - mStartTX - txBytes2G;
  } else {
      rxBytes2G = TrafficStats.getTotalRxBytes() - mStartRX - rxBytes3G;
      txBytes2G  = TrafficStats.getTotalTxBytes() - mStartTX - txBytes3G;
  }
