我并不完全了解Corona中点击和触摸之间的区别。我使用它们,当一个触摸一个对象时都听了事件,直到我写了这段代码,当触摸nextButton时它会改变图像。这就像当我触摸nextButton时,它会调用该函数两次。但是,当我将其更改为点击时,它工作顺利。那么你能告诉我触摸和点击之间有什么区别吗?当我在这段代码中使用touch时会出现什么问题?
function nextButton:touch(event)
if i==7 then
else
i=i+1
imageObject:removeSelf()
imageObject =display.newImage(imageTable[i]..".jpg")
imageObject.x=_W/2
imageObject.y=_H/2
end
end
nextButton:addEventListener("touch", nextButton)

在电晕触控听众中你有3个状态:
function listener(event)
if event.phase == "began" then
-- in the 1st tap the phase will be "began"
elseif event.phase == "moved" then
-- after began phase when the listener will be called with moved phase,like touched coordinates
elseif event.phase == "ended" then
--when the touch will end
end
end
nextButton:addEventListener("touch", listener)
- 〔〔 这是一个简单的触摸监听器,用于图像,自制按钮等,顺便说一下,当你需要按钮时,使用ui库完全为这个http://developer.coronalabs.com/code/enhanced-ui-library-uilua制作的] {/ p>
-- example for usage
local ui = require "ui" -- copy the ui.lua to your apps root directory
yourButton = ui.newButton{
defaultSrc = "menu/icon-back.png",--unpressed state image
x=85,
y=display.contentHeight-50,
defaultX = 110,
defaultY =80,
offset=-5,
overSrc = "menu/icon-back-2.png",--pressed state image
overX = 110,
overY = 80,
onEvent = buttonhandler,
id = "yourBtnId" -- what you want
}
local function buttonhandler(event)
if event.phase == "release" then
--if you have more buttons handle it whit they id-s
if event.id == "yourBtnId" then
-- when your button was finally released (like in 1st example ended, but this will be called only if the release target is your button)
end
end
end

“点击”是一种简短的触摸和释放动作。触摸可以是触摸,移动然后释放,或触摸和保持等。点击事件简化了您的代码,因为您只获得一个事件:点击发生。您不必为所有触摸状态编码。
典型的点击处理程序如下所示:
local function tapHandler(event)
-- do stuff
return true
end
哪里有一个触摸处理程序,它完全相同:
本地函数touchHandler(事件) 如果event.phase ==“结束”那么 - 做东西 结束 返回true 端
