ListItemButton - How to increase the height of button size?Hi

[Vijaykumar Walikar]

Hi All,

I am using ListItemButton in my code. But I am not able to change the size of list item button.

Please someone guide how to change the button size of ListItemButton.

Thank you!!!

Have you tried setting the 'size_hint_y' property to None, and the 'height' to '40', or whatever you want it to be? Setting the 'size_hint_y' to None is important when using many many of the layouts.

Thank you for your reply Zencode.

Yes I did try using 'size_hint_y' and 'height', but unfortunately it is not changing button size of ListItemButton.

However I can change the color of button using 'selected_color' and 'deselected_color' but I don't find any property to change button size.

Okay, listviews can be created many ways (simple lists, adaptors, etc), so it's hard to say. Have you tried setting the listview's row_height property?

Otherwise, please post a minimal example of the code so we can see exactly how you are creating you listview?

Peace out

I am using adapters.
As per your suggestion, I tried setting row_height property of listview but still unsuccessful :(

Please find the example code as requested.

Hello,

See the the arg_converter system in the ListAdpter. See extract of my code :

        ## Init data adapter
        list_item_args_converter = lambda row_index, obj: {'text': obj.text,
                                                           'is_selected': obj.is_selected,
                                                           'index' : obj.index,
                                                           'type_transaction' : obj.type_transaction,
                                                           'size_hint_y': None,
                                                           'height': '150sp'}
       
        p__list_adapter = ListAdapter(data=[],
                                      args_converter=list_item_args_converter,
                                      selection_mode='single',
                                      allow_empty_selection=True,
                                      template='TableurItem')

with it I can change the height to  '150sp'

With the arg_converter

Maybe someone else can shed light on why adding

<ListItemButton>:
size: (100, 50)

to Vijaykumar’s example kv will affect the ListItemButton’s height but

<ListItemButton>:
height: 50

won’t.

I tried to find a clue in the code but was unsuccessful.

I could finally achieve this using args_converter as below.

args_converter = lambda row_index, row_data: {'text':row_data, 'size_hint_y': None, 'height': '48dp'}

Thank you all for your help!!!
