如上同时可以搭配检测wifi是否通畅代码一块使用
搭配网络实时流量检测使用
Android实时检测网络(流量监控)直接复制可用

检测网络是否正常

利用ping功能来实现,跟电脑上ping效果一样

具体实现

/**
 * @ClassName: CheckNetStatus
 * @Description: 检测网络状态是否通畅
 * @Author: 有时有晌
 * @Date: 2022/1/24 16:47
 */
object CheckNetStatus {
    val TAG="CheckNetStatus"
    fun check(mContext:Activity,netStatusCallBack: NetStatusCallBack){
        var url ="www.baidu.com"
        //TaskManager 这个类是我本地在用的,大家用时候随便开个线程什么的就可以了。
        TaskManager.getInstance().execRunnable {
           LogUtil.e(TAG,"==-->WIFI可用检测")
           val stringBuilder = StringBuilder()
           val netState = toCheck(url, stringBuilder)
           LogUtil.e(TAG, "ping ${url} content \n${stringBuilder.toString()}")
           LogUtil.e(TAG, "ping ${url} state:${netState}")
           mContext.runOnUiThread {
               netStatusCallBack.netStatus(netState)
           }
       }
    }
    fun toCheck(ipAddress: String, stringBuilder: StringBuilder): Boolean {
        var result: String? = null
        try {
            var ip = "www.baidu.com" // ping 的地址,可以换成任何一种可靠的外网
            if (!TextUtils.isEmpty(ipAddress)) {
                ip = ipAddress
            }
            val p = Runtime.getRuntime().exec("ping -c 4 -w 100 $ip") // ping网址4次 响应100ms
            // 读取ping的内容,可以不加
            val input = p.inputStream
            val bufferedReader = BufferedReader(InputStreamReader(input))
            var content: String? = ""
            while (bufferedReader.readLine().also { content = it } != null) {
                stringBuilder.append(content)
                stringBuilder.append("\n")
            }
            // ping的状态
            val status = p.waitFor()
            if (status == 0) {
                result = "success"
                return true
            } else {
                result = "failed" //PING www.a.shifen.com (180.101.49.11) 56(84) bytes of data.   //64 bytes from 180.101.49.11: icmp_seq=2 ttl=49 time=53.3 ms  //64 bytes from 180.101.49.11: icmp_seq=3 ttl=49 time=51.3 ms  //64 bytes from 180.101.49.11: icmp_seq=4 ttl=49 time=50.2 ms
            }
        } catch (e: IOException) {
            result = "IOException"
        } catch (e: InterruptedException) {
            result = "InterruptedException"
        } finally {
            LogUtil.e(TAG, "result = $result")
        }
        return false
    }
    interface NetStatusCallBack{
        fun netStatus(isConnect:Boolean)
    }
}

调用

  • 在需要响应的页面中增加对应的执行方法,依次调用即可,网络检测,信号检测,可根据需求更改为定时轮询请求,以保证实时检测效果

MainActivity中方法

/**
     * wifi信号level
     * @param wifiLevel
     */
    public void setWifiLevel(int wifiLevel){
        switch (wifiLevel) {
            case 0:
                iv_net_status.setBackgroundResource(R.drawable.wifi_success0);
                break;
            case 1:
                iv_net_status.setBackgroundResource(R.drawable.wifi_success1);
                break;
            case 2:
                iv_net_status.setBackgroundResource(R.drawable.wifi_success2);
                break;
            default:
                iv_net_status.setBackgroundResource(R.drawable.wifi_success3);
                break;
        }
    }
    /**
     * 设置网络连接状态
     * 网络变化触发广播,广播变化触发检测网络
     * @param isConnect
     */
    public void setNetIv(boolean isConnect){
        if (isConnect){
            iv_net_status.setBackgroundResource(R.drawable.wifi_success3);
        }else{
            iv_net_status.setBackgroundResource(R.drawable.wifi_error);
        }
        CheckNetStatus.INSTANCE.check(this, new CheckNetStatus.NetStatusCallBack() {
            @Override
            public void netStatus(boolean isConnect) {
                if (isConnect){
                    iv_net_status.setBackgroundResource(R.drawable.wifi_success);
                    setWifiLevel(WifiCheckUtils.INSTANCE.checkWifiLevle(MainActivity.this, true));
                }else{
                    iv_net_status.setBackgroundResource(R.drawable.wifi_error);
                }
            }
        });
    }

可以扩展一下,当网络检测执行时,可将上述的网络信号制作成帧动画,可以实时显示检测效果。
