The below code gives Resources$NotFoundException

TypedValue value = new TypedValue();
((Activity)context).getResources().getValue(android.R.attr.listPreferredItemHeight, value, true);

EDIT: More code added in response to answer.

When I run the below code, all members of displayMetrics are 0. As is ret.

TypedValue value = new TypedValue();
DisplayMetrics displayMetrics = new DisplayMetrics();
((Activity)context).getTheme().resolveAttribute(android.R.attr.listPreferredItemHeight, value, true);
float ret = value.getDimension(displayMetrics);

    This works:

    TypedValue value = new TypedValue();
((Activity)context).getTheme().resolveAttribute(android.R.attr.listPreferredItemHeight, value, true);

    EDIT: You get zero because haven’t initialized the DisplayMetrics instance properly. It needs a frame of reference (a display) to do any meaningful conversion.

    android.util.TypedValue value = new android.util.TypedValue();
boolean b = getTheme().resolveAttribute(android.R.attr.listPreferredItemHeight, value, true);
String s = TypedValue.coerceToString(value.type, value.data);
android.util.DisplayMetrics metrics = new android.util.DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
float ret = value.getDimension(metrics);

    On my Nexus 1 s is 64.0dip and ret is 96.
