Answer 1

试试这个：

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

                 final android.net.NetworkInfo mobile1 = 
                                            connMgr.getActiveNetworkInfo();


                   if (mobile1 != null  && mobile1.isConnected() && mobile1.isAvailable() && (mobile1.getType() == ConnectivityManager.TYPE_MOBILE)) {
                Toast.makeText(CheckBoxTest.this," other Connection Found ",Toast.LENGTH_LONG).show();

                }

您可以尝试这样的事情： -

在您的Android清单中获得以下权限 -

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

在意图过滤器中使用具有以下操作的广播接收器 -

            <action android:name="android.net.conn.CONNECTIVITY_CHANGE" />

在接收器的onReceive方法中使用以下代码： -

@Override
public void onReceive(Context context, Intent intent) {
    super.onReceive(context, intent);
if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
            final ConnectivityManager connMgr = (ConnectivityManager) context
                    .getSystemService(Context.CONNECTIVITY_SERVICE);

            final android.net.NetworkInfo wifi = connMgr
                    .getNetworkInfo(ConnectivityManager.TYPE_WIFI);
            final android.net.NetworkInfo mobile = connMgr
                    .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
            if (wifi.isConnected() || mobile.isConnected()) {
                      Toast.makeText(LoginScreen.this," other Connection Found  
",Toast.LENGTH_LONG).show();

            }
else
{
Toast.makeText(LoginScreen.this,"No other Connection Found ",Toast.LENGTH_LONG).show();

}
        }

}

如果netwok被禁用，则mobiletype始终显示网络
