检查Android中的网络

Question

如何在Android中检查任何类型的网络状态？

Answer 1

if (Context.getSystemService(Context.CONNECTIVITY_SERVICE).getNetworkInfo(
        ConnectivityManager.TYPE_MOBILE)
    || Context.getSystemService(Context.CONNECTIVITY_SERVICE).getNetworkInfo(
        ConnectivityManager.TYPE_WIFI) {

    // do something
}

为了检查网络，此功能可以帮助您。

`public boolean InternetConnection() 

{
        ConnectivityManager connectivity = (ConnectivityManager) this.getSystemService(Context.CONNECTIVITY_SERVICE);
        if (connectivity != null) {
            NetworkInfo[] info = connectivity.getAllNetworkInfo();
            if (info != null) {
                for (int i = 0; i < info.length; i++) {
                    if (info[i].getState() == NetworkInfo.State.CONNECTED) {
                        return true;
                    }
                }
            }
        }
        return false;
    }`

如果网络在那里，它将返回true，否则它将返回false。

可以检查网络可用性

ConnectivityManager connectivityManager 
    = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
