android - Corona newScrollView hideScrollBar 仍然显示滚动条
<p><p>我这样声明 ScrollView :</p>
<pre><code>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,
}
</code></pre>
<p>不幸的是,无论我在“hideScrollBar”中设置什么,滚动条仍然可见。
有没有可能隐藏滚动条?</p></p>

<p><p>我发现了一个问题!
当您声明两个或多个 ScrollView 时会发生这种情况。它们中的最后一个覆盖了“hideScrollBar”设置。所以没有选择有两个 ScrollView ,一个有滚动条,一个没有滚动条。</p>
<p>这是证明问题的代码</p>
<p>properties.lua</p>
<pre><code>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
</code></pre>
<p>main.lua</p>
<pre><code>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,
