У меня есть Recyclerview. в адаптере это то, что у меня есть:
@Override
public void onBindViewHolder(@NonNull ViewHolder holder, final int position) {
//gradient is my arraylist that contains resource IDs. these are set in my fragment class
int res = gradient.get(position);
holder.parent.setBackground(ContextCompat.getDrawable(Application.getAppContext(), res));
}
и в своем фрагменте я передаю эти идентификаторы ресурсов адаптеру:
final ArrayList<Integer> gradients = new ArrayList<>();
gradients.clear();
gradients.add(R.drawable.gradient);
gradients.add(R.drawable.gradientgray);
gradients.add(R.drawable.gradient2);
RecyclerViewAdapter adapter = new RecyclerViewAdapter(gradients) //it has a constructor that gets the arraylist and sets it to the arraylist in adapter class.
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerView.setAdapter(adapter);
он работает на android> 4.4, но это вылетает при android 4.4 с исключением ResourceNotFound.

Один из рисоваемых объектов: (Все они одинаковые, но их цвета отличаются )
<?xml version="1.0" encoding="UTF-8"?>
<gradient
android:endColor="@android:color/holo_green_dark"
android:startColor="@android:color/holo_green_light"
android:type="linear" />
<corners
android:radius="0dp"/>
Drawables такие же, но только их цвета разные.
Также я попытался установить Drawable без Arraylist в Адаптер recyclerView (например, R.drawable.gradient вместо arraylist.get (position)) работает нормально. но используя arraylist, он отлично работает на более высоких android версиях. Я знаю, что аннулирование кэшей не связано, но это тоже не помогло.
