由于种种原因，这是行不通的：

For some reasons, this ain't working:

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

    if(wifi.isWifiEnabled())
    {
        tvStatus.setText("You WiFi is enabled");
    }
    else
    {
        tvStatus.setText("You WiFi is disabled");
    }

为什么是不是这方面的工作，我失去的东西吗？它编译和一切，但是当我要我的手机上运行它，它给了我辞去力误差

Why aint this working, am i missing something? And it compiles and everything but when i want to run it on my phone it gives me a force quit error

推荐答案

请确保您有使用你的清单中声明的​​WiFi正确的权限。我想你会需要 ACCESS_WIFI_STATE 在的最小值，或者如果你想启用的WiFi过，那么的 CHANGE_WIFI_STATE 会派上用场。

Make sure you have the right permissions for using WiFi declared in your Manifest. I think you will be needing ACCESS_WIFI_STATE at a mininum, or if you wish to enable WiFi too, then CHANGE_WIFI_STATE will come in handy.
