How to create listbox in kivy python?

I'm writing a file manager in kivy. How can I add listbox into kivy app?
And How can I bind functions to double-click.

IMO, you could make your 'listbox' using a RecycleView with Labels or BoxLayouts.

Something like:

RecycleView:
    id: rv
    viewclass: 'Label'
    RecycleBoxLayout:
        default_size: None, dp(56)
        default_size_hint: 1, None
        size_hint_y: None
        height: self.minimum_height
        orientation: 'vertical'

Then somewhere in your .py file:

...
dat = []
for l in ["label1", "label2"," label3"]:
    dat.insert(0,{'text':l,'color': (1,1,0,1)}

self.ids.rv.data = dat
    

Note that, the viewclass defines what will be the contents of your RecycleView , as such, this should be a valid Kivy class which in this case is just a list of Labels. For something more complicated, you can create your own widgets
