当我使用Android Studio模拟器（Nexus 4 API 23）来模拟我制作的应用程序时，它完美地工作。但是，当我用我的手机（三星SM-G3502T采用Android 4.3 API 18）来模拟相同的应用程序时，它会停留在该代码波纹管：代码适用于Android Studio模拟器，但不适用于我的Android手机
if(activity instanceof CategoriaListaActivity) {
boolean isSelected = (categoriaSelectedId == item.getCodigo());
((CategoriaViewHolder)holder).getNomeTextView().setTextColor(isSelected ? activity.getColor(R.color.colorPrimaryDark) : activity.getColor(R.color.colorAccent));
}
logcat的说：
