Android: how to get value of “listPreferredItemHeight” attribute in code?

Question

The below code gives Resources$NotFoundException

Answer 1

The shortest answer (without DisplayMetrics):

TypedValue typedValue = new TypedValue();
context.getTheme().resolveAttribute(android.R.attr.listPreferredItemHeight, typedValue, true);
int height = TypedValue.complexToDimensionPixelSize(typedValue.data, context.getResources().getDisplayMetrics());
