如何从微调器中选择 wifi 。我会感谢你的

Answer 1

将这段代码添加到您的监听器

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(true);

或用于切换行为

wifi.setWifiEnabled(!wifi.isWifiEnabled());

您可能需要为清单添加一些权限

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

有关更多选项，请参阅WifiManager ...

据我所知，热点功能没有API。您必须使用反射来调用这些方法......

Answer 2

要执行此操作，您需要获取微调器的文本（或选择），然后您需要切换WiFi设置。

在微调器上获取所选项目

Get spinner selected items text?

String Text = mySpinner.getSelectedItem().toString();
if (Text.equals("on"){
    //put below code here
} else {
    //put more code here
}
