信号强弱检测

/*** @ClassName: WifiCheckUtils* @Description: 页面切换检测wifi信号强弱* @Author: 有时有晌* @Date: /1/26 16:00*/object WifiCheckUtils {fun checkWifiLevle(context:Context,isConnect:Boolean):Int{var wifiType = 3try {var wifiManager = context!!.getSystemService(Context.WIFI_SERVICE) as WifiManagervar wifiInfo = wifiManager.connectionInfo as WifiInfovar wifiLever = wifiInfo.rssiif (isConnect){when (wifiLever) {in -50..0 -> {//信号最强wifiType = 0}in -70..-50 -> {//较强wifiType = 1}in -80..-70 -> {//较弱wifiType = 2}in -100..-80 -> {//微弱wifiType = 3}else->{wifiType = 3}}LogUtil.e("TAG","==-->WiFi信号强度$wifiType")setWifiLevel(wifiType)}} catch (e: Exception) {}return wifiType}/*** 设置wifi信号等级,这里是设置MainActivity页面的wifiLevel，用来设置wifi强度*/private fun setWifiLevel(wifiLevel:Int){try {MainActivity.act.wifiLevel = wifiLevel} catch (e: Exception) {}}}

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: /1/24 16:47*/object CheckNetStatus {val TAG="CheckNetStatus"fun check(mContext:Activity,netStatusCallBack: NetStatusCallBack){var url =""//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 {Status(netState)}}}fun toCheck(ipAddress: String, stringBuilder: StringBuilder): Boolean {var result: String? = nulltry {var ip = "" // 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.inputStreamval 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. (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 StatusCallBack() {@Overridepublic 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);}}});}
