首先,列表视图消失了,然后当我单击按钮时它变为可见,但我仅在具有 Android 3.1 的移动设备中出现此错误,列表视图未显示。我尝试使用 cachecolorhint #00000000 但它不起作用。我目前正在使用 Xamarin 进行开发。

C#代码:
public void VisibilidadBloqueResultado(bool visible)
{
resultado.Visibility = visible == true ? ViewStates.Visible : ViewStates.Gone;
}
设置 listVisible 后,我设置了 de Adapter
adapter = new ListVisitaEmpresasAdapter(atx1, lista);
empresas.Adapter = adapter;
empresas.ItemClick += empresas_ItemClick;
