首先listview是GONE然後它會變得可見，當我點擊一個按鈕，但即時通訊只有在移動設備與Android 3.1列表視圖不顯示。我嘗試使用cachecolorhint＃00000000，但它不起作用。我正在用Xamarin開發。對話框中的黑色屏幕ListView Xamarin Android
誤差圖像： http://i471.photobucket.com/albums/rr77/lithium1818/Android_20140924.png
C＃代碼：
public void VisibilidadBloqueResultado(bool visible)
{
resultado.Visibility = visible == true ? ViewStates.Visible : ViewStates.Gone;
}
後我設置listVisible我設置德適配器
adapter = new ListVisitaEmpresasAdapter(atx1, lista);
empresas.Adapter = adapter;
empresas.ItemClick += empresas_ItemClick;

很難幫助沒有代碼和XML你知道嗎？ – 2014-09-24 16:52:57
我剛剛發佈了XML代碼 – CheckM 2014-09-24 17:08:56
您能告訴我們如何將listview可見性設置爲可見？ – 2014-09-24 17:18:53
