Android获取网速的方法

private long lastTotalRxBytes = 0; private long lastTimeStamp = 0; /** * 得到网络速度 * @param context * @return */ public String getNetSpeed(Context context) { String netSpeed = "0 kb/s"; long nowTotalRxBytes = TrafficStats.getUidRxBytes(context.getApplicationInfo().uid)== TrafficStats.UNSUPPORTED ? 0 :(TrafficStats.getTotalRxBytes()/1024);//转为KB; long nowTimeStamp = System.currentTimeMillis(); long speed = ((nowTotalRxBytes - lastTotalRxBytes) * 1000 / (nowTimeStamp - lastTimeStamp));//毫秒转换 lastTimeStamp = nowTimeStamp; lastTotalRxBytes = nowTotalRxBytes; netSpeed = String.valueOf(speed) + " kb/s"; return netSpeed; }
