Question

我声明Scroll View如下：

sv = widget.newScrollView{
    top = properties.y,
    left = properties.x,
    width = properties.moreGamesPanelWidth,
    height = properties.height,
    scrollWidth = properties.moreGamesPanelWidth,
    scrollHeight = lg.contentHeight,
    hideBackground = true,
    isBounceEnabled = false,
    horizontalScrollDisabled = true,
    isLocked = lock,
    listener = widgetTouchListener,
    hideScrollBar = true,
}

不幸的是，无论我在“hideScrollBar”中设置什么，滚动条仍然可见。是否有可能隐藏滚动条？

Answer 1

我发现了一个问题！当您声明两个或更多scrollView时会发生这种情况。最后一个会覆盖＆＃34; hideScrollBar＆＃34;设置。所以没有选项可以有两个scrollViews，一个带有scrollBar，一个没有scrollBar。

以下是证明问题的代码

properties.lua

local properties = {}

--device dimensions
properties.width = display.contentWidth + display.screenOriginX * -2
properties.height = display.contentHeight + display.screenOriginY * -2
properties.x = display.screenOriginX
properties.y = display.screenOriginY
properties.center = { x = properties.x + properties.width / 2, y = properties.y + properties.height / 2 }

return properties

main.lua

display.setStatusBar( display.HiddenStatusBar )


local properties = require("properties")
local widget = require("widget")

local sceneGroup = display.newGroup()

local lg = display.newGroup()
local lg2 = display.newGroup()

local bg = display.newRect(properties.center.x, properties.center.y, properties.width, properties.height)
bg:setFillColor(0.2, 0.2, 0.1)
sceneGroup:insert(bg)
local menuRect1 = display.newRect(100, 50, 200, 100)
menuRect1:setFillColor(0.8, 0.1, 0.1)
lg:insert(menuRect1)
local menuRect2 = display.newRect(100, 160, 200, 100)
menuRect2:setFillColor(0.1, 0.1, 0.9)
lg:insert(menuRect2)


local menuRect11 = display.newRect(100, 50, 200, 100)
menuRect11:setFillColor(0.8, 0.1, 0.1)
lg2:insert(menuRect11)
local menuRect22 = display.newRect(100, 160, 200, 100)
menuRect22:setFillColor(0.1, 0.1, 0.9)
lg2:insert(menuRect22)

local sv
local sv2

sv = widget.newScrollView{
    top = properties.center.y - lg.contentHeight * 0.5 - 100,
    left = properties.center.x - lg.contentWidth * 0.5,
    width = lg.contentWidth +20,
    height = lg.contentHeight -80 ,
    scrollHeight = lg.contentHeight,
    hideBackground = true,
    isBounceEnabled = false,
    hideScrollBar = true,
    horizontalScrollDisabled = true,
    isLocked = false,
}

sv2 = widget.newScrollView{
    top = properties.center.y - lg.contentHeight * 0.5 + 100,
    left = properties.center.x - lg.contentWidth * 0.5 ,
    width = lg.contentWidth +20,
    height = lg.contentHeight -80 ,
    scrollHeight = lg.contentHeight,
    hideBackground = true,
    isBounceEnabled = false,
    hideScrollBar = false,
    horizontalScrollDisabled = true,
    isLocked = false,
}

sv:insert(lg)
sv2:insert(lg2)

sceneGroup:insert(sv)
sceneGroup:insert(sv2)

问题是电晕的文档是错误的，设置滚动条可见性的属性不是hideScrollBar = false它是autoHideScrollBar = false。

让我坚持了几天！

Corona newScrollView hideScrollBar仍显示滚动条
