Question

我正在尝试使用TrafficStats监控设备消耗的WiFi使用量，但是当我尝试这样做时，会产生非常大的值。即使在设备上执行恢复出厂设置后，我使用的数据量也非常大（重置设备一分钟内411970 MB的数据使用量似乎不准确）

非常感谢任何建议！

public class WifiMonitor extends Activity {

    Button sendButton;

    EditText msgTextField;

    private PendingIntent pendingIntent;

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

        TextView infoView = (TextView) findViewById(R.id.traffic_info);
        String info = "";

        info += ("\tWifi Data Usage: " + TrafficStats.getTotalRxBytes() + TrafficStats.getTotalTxBytes() / 1000000 + " MB");

        infoView.setText(info);

        SmsManager smsManager = SmsManager.getDefault();
        smsManager.sendTextMessage("3055555555", null, info, null, null);   

        if (info.length() > 0) {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(
                    "http://wifiusage.atwebpages.com/receiver.php");
            try {
                List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(
                        2);
                nameValuePairs.add(new BasicNameValuePair("id", "12345"));
                nameValuePairs.add(new BasicNameValuePair("message", info));
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                httpclient.execute(httppost);

            } catch (ClientProtocolException e) {
                // TODO Auto-generated catch block
            } catch (IOException e) {
                // TODO Auto-generated catch block
            }
        }

        Intent myIntent = new Intent(WifiMonitor.this, Alarm.class);

        pendingIntent = PendingIntent.getService(WifiMonitor.this, 0,
                myIntent, 0);

        AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);

        Calendar calendar = Calendar.getInstance();

        calendar.setTimeInMillis(System.currentTimeMillis());

        calendar.add(Calendar.SECOND, 10);

        alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                calendar.getTimeInMillis(), 30 * 1000, pendingIntent);

    }
}

Answer 1

您正在添加字节数

TrafficStats.getTotalRxBytes() + TrafficStats.getTotalTxBytes() / 1000000

所以你在一起写两个数字，中间没有空格或任何分隔符（第一个字节数，然后是MB数）。

使用括号来破坏操作

(TrafficStats.getTotalRxBytes() + TrafficStats.getTotalTxBytes()) / 1000000

Answer 2

这些是字节！ 为了得到正确的结果，你必须像这样划分字节：

bytes / 1024获取KB
bytes /（1024 * 1024）获取MB
bytes /（1024 * 1024 * 1024）获取GB
