Another answer

public float getItemHeight() {
    TypedValue value = new TypedValue();
    DisplayMetrics metrics = new DisplayMetrics();

    context.getTheme().resolveAttribute(
            android.R.attr.listPreferredItemHeight, value, true);
    ((WindowManager) (context.getSystemService(Context.WINDOW_SERVICE)))
            .getDefaultDisplay().getMetrics(metrics);

    return TypedValue.complexToDimension(value.data, metrics);
}

it maybe more useful.
