@mikael Thanks for the pull to refresh example. I really appreciate the help. I had a couple issues. The biggest issue was only being able to refresh once after the view is loaded. The second Issue was when pulled too far down, the refresh function was called multiple times. I think I solved these issues. I attached the solution I came up with below.
import ui, sound
class scrollViewDelegate:
maxPull = -100
def __init__(self):
self.refresh = False
def scrollview_did_scroll(self, scrollview):
x, y = scrollview.content_offset
if y <= 0:
delta = max(y, self.maxPull) / self.maxPull
if (y <= self.maxPull and not scrollview.tracking and
scrollview.decelerating and not self.refresh):
scrollview['refresh_bg'][
'refresh_label'].text_color = 0.50, 0.50, 0.50, delta
self.contentRefresh()
elif (y <= self.maxPull - 10 and scrollview.tracking and
not scrollview.decelerating and not self.refresh):
scrollview['refresh_bg']['refresh_label'].text = 'Release to refresh'
scrollview['refresh_bg'][
'refresh_label'].text_color = 0.50, 0.50, 0.50, delta
elif (y >= self.maxPull - 10 and scrollview.tracking and
not scrollview.decelerating and not self.refresh):
scrollview['refresh_bg']['refresh_label'].text = 'Pull to refresh'
scrollview['refresh_bg'][
'refresh_label'].text_color = 0.60, 0.60, 0.60, delta
def contentRefresh(self):
self.refresh = True
sound.play_effect('ui:click3')
#print('refreshing')
ui.delay(self.contentDidRefresh, 0)
def contentDidRefresh(self):
self.__init__()
w, h = ui.get_screen_size()
sv = ui.ScrollView()
sv.name = 'Scrollview'
sv.always_bounce_horizontal = False
sv.always_bounce_vertical = True
sv.directional_lock_enabled = True
sv.scroll_indicator_insets = (10, 0, 10, 0)
sv.bounces = True
sv.paging_enabled = False
sv.indicator_style = 'black'
sv.scroll_enabled = True
sv.background_color = 1.0, 1.0, 1.0
sv.content_inset = (0, 0, 0, 0)
sv.content_size = (w - 10, h*2)
sv.delegate = scrollViewDelegate()
rb = ui.View()
rb.name = 'refresh_bg'
rb.alpha = 1.0
rb.background_color = 0.90, 0.90, 0.90
rl = ui.Label()
rl.name = 'refresh_label'
rl.alpha = 1.0
rl.alignment = ui.ALIGN_CENTER
#rl.background_color = 'white'
rl.text = 'Pull to Refresh'
rl.text_color = None
rl.font = ('<system>', 14)
rb.add_subview(rl)
sv.frame = (0, 0, w, 0.5)
rb.frame = (0, -600, sv.width, 600)
rl.frame = (0, rb.height - 32, sv.width, 32)
sv.add_subview(rb)
sv.present('fullscreen')
