  • @Ahmed-Elshorbagy Are you saying you don’t know why the height is not correct? It looks like everything is rendering other than height, which you have the calculated height function, so I assume you have tried modifying that.

  • The height is not right ,yes. I have not tried to modify the height, do I have to modify the the height?

  • @Ahmed-Elshorbagy Yes, you have it saying if Android be 48 pixels high else 44. Try changing that to maybe 54 : 50. You can increment the numbers (the same amount for each) until you get what you want.

  • I will try it, thank you.

  • Try without calculateItemHeight.

    From the docs:
    Should return the height of an item. The index is provided as an argument. This is important when rendering lists where the items have different height. The function is optional and if it isn’t present the height of the first item will be automatically calculated and used for all other items.

  • @Piotr-Mitoraj Thank you

  • Onsen UI

    That works if all your items have the same height. Otherwise, you need to provide a function calculating it. We just merged a new version of LazyRepeat where this should not be necessary anymore, it will be released soon :)
