android - 用于启动器的 android IPTV 盒编程

Question

我正在android中编写一个iptv设置框启动器，我正在尝试找出以太网连接信息（用户是否使用以太网电缆连接），请帮助...如果问题不清楚，我深表歉意。请帮助我非常需要它，从过去三天开始就卡住了。

Answer 1

您可以通过以下方式检查您是否连接在以太网或 Wifi 中ConnectivityManager：

ConnectivityManager connManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo wifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
NetworkInfo ethernet = connManager.getNetworkInfo(ConnectivityManager.TYPE_ETHERNET);

// get the ethernet state with : ethernet.getState()
// get the Wifi state with : wifi.getState()

您需要在清单中添加：

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

您可以通过 a 注册连接事件BroadcastReceiver，查看此示例

或者您可以使用为您制作的这个库

Answer 2

private Boolean isNetworkAvailable() {
        ConnectivityManager connectivityManager
                = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
        NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
        return activeNetworkInfo != null && activeNetworkInfo.isConnectedOrConnecting();
}

public Boolean isWifiConnected(){
        if(isNetworkAvailable()){
            ConnectivityManager cm
                    = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
            return (cm.getActiveNetworkInfo().getType() == ConnectivityManager.TYPE_WIFI);
        }
        return false;
}

public Boolean isEthernetConnected(){
        if(isNetworkAvailable()){
            ConnectivityManager cm
                    = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
            return (cm.getActiveNetworkInfo().getType() == ConnectivityManager.TYPE_ETHERNET);
        }
        return false;
}

然后 ：

if(isEthernetConnected()){
    // connected
}
else {
    //not connected
}
