问题 How can I search in recycleview with updated review .I can also search now. But when I type 3 alphabets in txt_input it search for the same result. and gives the list which contains those 3 alphabets. But i want to make as a search engine. so if I type "TAT" it will show me TATA MOTORS PVT LTD,Tata Elxsi Limited,Tata Steel Limited,etc. But when I type "TATA MO" it doesnot update the recycleview with new search suggestions.

问题 i was just playing with Python and kivy , I've loaded my String data into a RecyclerView as per the kivy official documentation. but I've faced trouble on loading an object to multiple columns inside the list like a form data. for example i wanted to have name,family name and age to three columns with title headers row by row , I've also tried RecyclerGridLayout with 3 columns , but it can load just name into grids regardless of row by row requirement <RV>: viewclass: 'Label' RecycleBoxLayout
