Android:仅通过 WIFI 发送数据 [英] Android: Send data only by WIFI

问题描述

我有一个在后台运行并向服务器发送数据的服务，我只想通过 wifi 而不是其他方式(gprs 或其他方式)发送这些数据，这可能吗?如果是，我怎样才能做到这一点?如果您有示例代码或链接，那就太好了.谢谢.

推荐答案

final ConnectivityManager connMgr = (ConnectivityManager)
 this.getSystemService(Context.CONNECTIVITY_SERVICE);

final android.net.NetworkInfo wifi =
 connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);

NetworkInfo 结构应该具有 Wifi 子系统的连接状态.查看文档:

The NetworkInfo structure should have the connectivity state of the Wifi Subsystem. Look at the documentation:

使用isConnected方法查看wifi是否连接.轻松点！

Use the isConnected method to see if wifi is connected. Easy Peasy!
