How to change the height of the item of roller?

Hi,
I find the height of item of roller is not changed,How can i change it?

Do you mean the height of the roller itself or the selected item?
For the roller itself use: lv_roller_set_visible_row_count
For the height of the selected element set the font.line_space in LV_ROLLER_STYLE_BG
