[RecycleView] Print data from selected item

[Ricardo Couto]

Hello all,

Probably a very noob question: How can I print the name of the selected item in this RecycleView?

The code works (just removed all unnecessary parts) :)

python:

        self.my_list.data = [{

            'name': p.name,

            'age': p.age,}

            for p in people_list]

kv:

        RecycleView:

            id: my_list

            scroll_type: ['bars', 'content']

            scroll_wheel_distance: dp(114)

            bar_width: dp(8)

            viewclass: 'Tits'

            RecycleBoxLayout:

                default_size: None, dp(36)

                default_size_hint: 1, None

                size_hint_y: None

                height: self.minimum_height

                orientation: 'vertical'

                spacing: dp(2)

Thanks!

Hello,

This was the solution I implemented in a program I wrote earlier in the year. I believe this was straight from the documentation too.

You also need to add/replace this to your KV : 

<SelectableLabel>:
    # Draw a background to indicate selection
    canvas.before:
        Color:
            rgba: (0.5, 0.2, 0.1, 1) if self.selected else (0.5, 0.5, 0.5, 1)
        Rectangle:
            pos: self.pos
            size: self.size

# This is within whatever the main class is not within the above class, basically just

# adjust some of these properties in your current declaration you have below.

      RecycleView:

            id: rv

            scroll_type: ['bars', 'content']

            scroll_wheel_distance: dp(114)

            bar_width: dp(10)

            viewclass: 'SelectableLabel'

            SelectableRecycleBoxLayout:

                default_size: None, dp(56)

                default_size_hint: 1, None

                size_hint_y: None

                height: self.minimum_height

                orientation: 'vertical'

                multiselect: False

                touch_multiselect: False

class SelectableRecycleBoxLayout(FocusBehavior, LayoutSelectionBehavior,
                                 RecycleBoxLayout):
    """ Adds selection and focus behaviour to the view. """




class SelectableLabel(RecycleDataViewBehavior, Label):
    """ Add selection support to the Label """
    index = None
    selected = BooleanProperty(False)
    selectable = BooleanProperty(True)


    def refresh_view_attrs(self, rv, index, data):
        """ Catch and handle the view changes """
        self.index = index


        return super(SelectableLabel, self).refresh_view_attrs(
            rv, index, data)


    def on_touch_down(self, touch):
        """ Add selection on touch down """
        if super(SelectableLabel, self).on_touch_down(touch):
            return True
        if self.collide_point(*touch.pos) and self.selectable:
            return self.parent.select_with_touch(self.index, touch)


    def apply_selection(self, rv, index, is_selected):
        """ Respond to the selection of items in the view. """
        self.selected = is_selected
        if is_selected:
            print("selection changed to {0}".format(rv.data[index]))
