如何将圆的边缘对齐在一起？

Question

如何将圆的边缘对齐在一起？盒子的边缘是对齐的，但我的圆圈 circumference/edge 没有对齐，而是它们占据了彼此的空间..

    local areaPadding = 5
    local topPadding = 160
    local answerOffset = 6
    local area = answer_rect.width - (areaPadding*-5)
    local answerHeight = (area-topPadding-(answerOffset*#q.answers))/#q.answers
    local textX = numberX + 20
    local textW = _W - textX - 24

    local y = answer_rect.x + areaPadding + topPadding
    local howManyAnswers = #q.answers

-- 确保答案适合屏幕大小，如果需要的话，减少 answerHeight 本地偏移量 = (_W - (howManyAnswers * (answerHeight+answerOffset) - answerOffset)) * 0.5

    for i=1, howManyAnswers do
        local rect = display.newCircle(quizGroup, offset + (answerHeight+answerOffset)*(i-1), y, answerHeight, answerHeight )
        rect.anchorX, rect.anchorY = 0, 0
        rect.id = "answer"
        rect.index = i
        rect:setFillColor(0.1)
        rect:addEventListener("touch", buttonTouched)

        local answer = display.newText({parent=quizGroup, text=q.answers[i], width=textW, height=0, font=native.systemFont, fontSize=150})
        answer.x = rect.x + rect.width * 0.3
        answer.y = rect.y + rect.height * 0.5
        answer.anchorX = 0
        answer:setFillColor(1)
    end
end

Answer 1

尝试

local _W = display.contentWidth
local _H = display.contentHeight

local areaPadding = 12
local topPadding = 16
local answerOffset = 30 -- you put in this space labels
local area = answer_rect.height - (areaPadding*2.5)
local howManyAnswers = #q.answers
local textX = numberX + 20
local textW = _W - textX - 24
local answerHeight = (area-topPadding-(answerOffset*#q.answers))/howManyAnswers 
local y = answer_rect.x + areaPadding + topPadding 
-- make sure answers fit screen size if neccessary decrease answerHeight
local offset = (_W - (howManyAnswers * (answerHeight+answerOffset))) * 0.5

for i=1, howManyAnswers do
  local rect = display.newRect(quizGroup, offset + answerOffset +(answerHeight+answerOffset)*(i-1), y, answerHeight, answerHeight)
  rect.anchorX, rect.anchorY = 0, 0
  rect.id = "answer"
  rect.index = i
  rect:setFillColor(0.1)
  rect:addEventListener("touch", buttonTouched)

  local label = display.newText({parent=quizGroup, text=i..".", font=native.systemFont, fontSize=20})
  label.x = rect.x - answerOffset * 0.5
  label.y = rect.y + 0.5 * rect.height 
  label:setFillColor(0.4)

  local answer = display.newText({parent=quizGroup, text=q.answers[i], width=textW, height=0, font=native.systemFont, fontSize=150})
  answer.x = rect.x + rect.width * 0.5
  answer.y = rect.y + rect.height * 0.5
  answer:setFillColor(1)
end
