+
+> Android 全局网络变化监听
+
+##  How to
+To get a Git project into your build:
+
+Step 1. Add the JitPack repository to your build file
+
+Add it in your root build.gradle at the end of repositories:
+
+``` glide
+allprojects {
+    repositories {
+        ...
+        maven { url 'https://jitpack.io' }
+    }
+}
+```
+
+Step 2. Add the dependency
+
+``` glide
+dependencies {
+        implementation 'com.github.kongqw:NetworkMonitor:1.0.0'
+}
+```
+
+## 使用
+### 初始化
+
+在`Application`中初始化
+
+``` kotlin
+NetworkMonitorManager.getInstance().init(this)
+```
+
+### 注册
+
+在需要监听网络状态的页面进行注册
+
+``` kotlin
+NetworkMonitorManager.getInstance().register(this)
+```
+
+### 反注册
+
+``` kotlin
+NetworkMonitorManager.getInstance().unregister(this)
+```
+
+### 监听网络状态变化
+
+``` kotlin
+@NetworkMonitor
+fun onNetWorkStateChange(networkState: NetworkState) {
+    when (networkState) {
+        NetworkState.NONE -> {
+            // TODO 暂无网络 
+        }
+        NetworkState.WIFI -> {
+            // TODO WIFI网络 
+        }
+        NetworkState.CELLULAR -> {
+            // TODO 蜂窝网络 
+        }
+    }
+}
+```
+
+也可以监听指定网络状态，例如
+
+``` kotlin
+@NetworkMonitor(monitorFilter = [NetworkState.NONE])
+fun onNetWorkStateChangeNONE(networkState: NetworkState) {
+    // TODO 网络断开时回调
+}
+```
+
+``` kotlin
+@NetworkMonitor(monitorFilter = [NetworkState.WIFI])
+fun onNetWorkStateChange1(networkState: NetworkState) {
+    // TODO WIFI连接上的时候回调
+}
+```
+
+``` kotlin
+@NetworkMonitor(monitorFilter = [NetworkState.WIFI, NetworkState.CELLULAR])
+fun onNetWorkStateChange2(networkState: NetworkState) {
+    // TODO 连接上WIFI或蜂窝网络的时候回调
+}
+```
