Android实时检测网络（流量监控）直接复制可用

Android实时检测网络（流量监控）直接复制可用

效果如下

可搭配Android检测wifi信号强度，检测网络是否通畅 使用

创建工具类

import android.content.Context;
import android.net.TrafficStats;
import android.os.Handler;
import android.os.Message;

import java.util.Timer;
import java.util.TimerTask;

/**
 * @ClassName: NetWorkListenerUtils
 * @Description: 实时网络流量检测
 * @Author: 有时有晌
 * @Date: 2022/3/14 10:13
 */
public class NetWorkListenerUtils {
    private Context context;
    private Handler mHandler;

    private long lastTotalRxBytes = 0;
    private long lastTimeStamp = 0;
    private Timer timer;

    public NetWorkListenerUtils(Context context, Handler mHandler) {
        this.context = context;
        this.mHandler = mHandler;
    }

    public void startShowNetSpeed() {
        lastTotalRxBytes = getTotalRxBytes();
        lastTimeStamp = System.currentTimeMillis();
        // 1s后启动任务，每2s执行一次、
        if (timer == null) {
            timer=new Timer();
        }
        timer.schedule(task, 1000, 1000);

    }

    public void unbindShowNetSpeed() {
        if (timer != null) {
            timer.cancel();
        }
    }

    private long getTotalRxBytes() {
        return TrafficStats.getUidRxBytes(context.getApplicationInfo().uid) == TrafficStats.UNSUPPORTED ? 0 : (TrafficStats.getTotalRxBytes() / 1024);//转为KB
    }

    private void showNetSpeed() {
        long nowTotalRxBytes = getTotalRxBytes();
        long nowTimeStamp = System.currentTimeMillis();
        long speed = ((nowTotalRxBytes - lastTotalRxBytes) * 1000 / (nowTimeStamp - lastTimeStamp));//毫秒转换
        long speed2 = ((nowTotalRxBytes - lastTotalRxBytes) * 1000 % (nowTimeStamp - lastTimeStamp));//毫秒转换

        lastTimeStamp = nowTimeStamp;
        lastTotalRxBytes = nowTotalRxBytes;
        if (mHandler != null) {
            Message msg = mHandler.obtainMessage();
            msg.what = 100;
            msg.obj = String.valueOf(speed) + "." + String.valueOf(speed2) + " kb/s";
            mHandler.sendMessage(msg);//更新界面
        }
    }

    TimerTask task = new TimerTask() {
        @Override
        public void run() {
            showNetSpeed();
        }
    };
}

显示页面代码逻辑

创建对应的handler用于更新ui所展示的网速

    private Handler mHnadler = new Handler(){
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
                case 100:
                    tv_speed.setText("当前网速： " + msg.obj.toString());
                    break;
            }
            super.handleMessage(msg);
        }
    };

工具类调用

new NetWorkListenerUtils(this,mHnadler).startShowNetSpeed();

布局

如上布局中主要用到的就是tv_speed这个TextView

注意：如使用请关注性能问题
