插入小部件按钮后滚动视图不滚动

Question

我正在制作我们的顶点项目，它是为了备灾，但我的问题是这个滚动视图在放置小部件选项卡后不会滚动。 它在放置按钮之前滚动。 我使用小部件按钮，使其看起来像这样。

代码：

local storyboard = require( "storyboard" )
local scene = storyboard.newScene()

local widget = require "widget"

function scene:createScene( event )
    local group = self.view 

    background = display.newImage("ehead.png", true)
    background.x = 360
    background.y = 150
    group:insert(background)

    local function onBackbuttonRelease()    
            storyboard.gotoScene( "mainmenu", "slideRight", 200)
            return true
    end


    local Backbutton = widget.newButton
    {
        defaultFile = "back.png",
        overFile = "back2.png",
        onRelease = onBackbuttonRelease
    }
    Backbutton.x = 45 ; Backbutton.y = 105
    group:insert( Backbutton )

local scrollView = widget.newScrollView
{
    top = 180,
    left = 6,
    width = display.contentWidth,
    height = display.contentHeight,
    scrollWidth = display.contentWidth,
    scrollHeight = 8000
}
group:insert(scrollView)
local options = {
    text = "",
    width = 700,
    font = "HelveticaNeue",
    fontSize = 50,
    align = "center"
}

    local altavas= widget.newButton
    {
        defaultFile = "al.png",
        overFile = "al2.png",
        onRelease = onaltavasRelease
    }
    altavas.x = 354; altavas.y = 70
    scrollView:insert( altavas )

    local balete= widget.newButton
    {
        defaultFile = "ba.png",
        overFile = "ba2.png",

    }
    buruanga.x = 354; buruanga.y = 430
    scrollView:insert( buruanga )

    local ibajay = widget.newButton
    {
        defaultFile = "ib.png",

    scrollView:insert( nw )

    local numancia = widget.newButton

scene:addEventListener( "createScene", scene )

return scene

这很简单，只需使用： https : //docs.coronalabs.com/api/type/ScrollViewWidget/takeFocus.html

但我鼓励您制作自定义按钮，而不是使用 widget.newButton。

但是，如果您仍然喜欢使用 widget.newButton，请看这里： https ://forums.coronalabs.com/topic/42033-widget-button-inside-a-scrollview-doesnt-work-when-i-use-the -takefocus方法/
