Android 连接wifi和创建WIFI热点 demo

android wifi

在Android平台上，连接WiFi和创建WiFi热点是两个重要的网络功能，尤其对于移动设备而言，它们在日常生活和工作中扮演着至关重要的角色。这个“Android 连接WiFi和创建WIFI热点 demo”应该是一个示例项目，它展示了如何通过编程方式来实现这些功能。下面将详细介绍这两个功能的实现原理和步骤。 **一、连接WiFi** 1. **权限获取**：在AndroidManifest.xml文件中添加必要的权限，如`ACCESS_FINE_LOCATION`和`CHANGE_WIFI_STATE`，确保应用能够读取和更改WiFi状态。 ```xml

``` 2. **WiFiManager接口**：Android系统提供`WifiManager`类，它是管理WiFi连接的主要接口。通过`Context.getSystemService(Context.WIFI_SERVICE)`获取`WifiManager`实例。 3. **扫描可用网络**：调用`WifiManager.scanResults`方法，可以获取当前区域内所有可用的WiFi网络信息。 4. **选择并连接网络**：使用`WifiManager.addNetwork(WifiConfiguration)`方法创建一个新的WiFi配置，其中`WifiConfiguration`包含了SSID（网络名）和密码等信息。然后，调用`WifiManager.enableNetwork(int networkId, boolean disableOthers)`连接到指定的网络。 5. **状态监听**：为了实时获取WiFi连接的状态变化，可以注册一个`BroadcastReceiver`，监听`CONNECTIVITY_ACTION`广播，以便在连接成功或失败时进行相应处理。 **二、创建WiFi热点** 1. **配置热点**：确保应用具有`ACCESS_NETWORK_STATE`和`CHANGE_WIFI_MULTICAST_STATE`权限。接着，通过`WifiManager`实例，调用`createWifiAccessPoint Configuration, WifiManager.WifiConfiguration)`方法创建WiFi热点。`Configuration`对象包含热点的SSID和密码。 2. **启动和关闭热点**：使用`WifiManager.setWifiEnabled(false)`关闭WiFi连接，再调用`WifiManager.startLocalOnlyHotspot(WifiConfiguration, LocalOnlyHotspotCallback)`启动本地热点。当不再需要热点时，通过`WifiManager.stopLocalOnlyHotspot()`关闭它。 3. **热点状态监控**：与连接WiFi类似，可以创建一个`BroadcastReceiver`监听`WIFI_AP_STATE_CHANGED_ACTION`广播，以获取热点的开启和关闭状态。在实际应用中，需要注意的是，从Android 6.0（API级别23）开始，系统引入了运行时权限，需要在应用运行时请求用户授予相关权限。此外，不同的Android版本可能对创建和连接WiFi热点的API有所调整，因此开发时应考虑兼容性问题。 `AndroidSpotDemo`这个项目很可能是包含了以上功能的示例代码，包括界面交互、事件处理和逻辑控制。开发者可以通过阅读和学习这个项目，了解如何在Android应用中实现连接WiFi和创建WiFi热点的功能，这对于开发涉及网络共享或者需要自定义网络连接的应用非常有帮助。
