android连接指定的wifi

❶ Android如何添加隐藏的无线wifi配置文件

1、打开 设定 页面，点击 Wi-Fi

2、点击 添加WLAN网络

3、手动输入路由器的SSID、无线密码等参数，点击 储存，保存无线配置文件

4、无线配置文件添加完成，无线信号显示已连接

注意：添加了无线配置文件，手机重启后（或手机从外面拿回家）会自动连接路由器的无线信号，不需要重新添加无线配置文件。

❷ android怎么自动连接以zd开头的wifi，知道密码，想用代码直接连接

public class WifiAutoConnectManager {

return true; }}

❸ Android手机如何设置wifi设备名

1、首先打开手机设置，点击选择“其他无线连接”按钮。

❹ android wifi 开发中 如何判断成功连接上了指定的wifi热点

首先通过WifiManager对象获取系统服务的WIFI_SERVICE，然后调用getConnectionInfo（）获得WifiInfo对象，再通过WifiInfo对象获取已连上wifi的SSID(实际上是housyunhin说的WifiInfo.getSSID（）和其他wifi信息)，之后判断是否匹配即可

❺ android 命令怎么连接wifi点
