我有一个左滑动菜单的应用程序，就像任何典型的谷歌应用程序中的应用程序。当用户向左滑动菜单时，我有一个触摸处理程序来关闭菜单，但菜单也使用一个表来显示菜单的元素，并且此表有一个onRowTouch句柄来处理单击行按钮时的处理。电晕处理非常特定的触摸事件
我现在的问题是，当用户想要滑动左侧菜单关闭它时，如果用户的手指与任何按钮接触，它会抛出onRowTouch而不是关闭菜单。如果用户试图通过向左滑动按钮来关闭菜单，它将再次抛出onRowTouch而不是关闭菜单。
有没有办法让应用程序知道打算关闭菜单的触摸和打算点击的打算之间的区别？
我的代码：
local sideMargin= 16
local function panelTransDone(target)
--native.showAlert("Panel", "Complete", { "Okay" })
if (target.completeState) then
print("PANEL STATE IS: "..target.completeState)
end
end
--Panel being the menu
panel = widget.newPanel{
location = "left",
onComplete = panelTransDone,
width = display.contentWidth * 0.8,
height = display.contentHeight,
speed = 150,
}
panel.background = display.newRect(0, 0, panel.width, panel.height)
panel.background:setFillColor(1)
panel:insert(panel.background)
--Decorator elements omitted for readability
local menuRows= {
{title = "Calendar", page = "calendar", image = "images/event/Icon.png"},
{title = "Volunteer", page = "volunteer", image = "images/volunteer/Icon.png"},
{title = "Contact Us", page = "contact", image = "images/chat/Icon.png"},
{title = "About Us", page = "about", image = "images/info/Icon.png"},
{title = "Sign Out", page = "signOut", image = "images/account/Icon.png"}
}
local function onRowRender(event)
-- Get reference to the row group
local row = event.row
local params=event.row.params
-- Cache the row "contentWidth" and "contentHeight" because the row bounds can change as children objects are added
local rowHeight = row.contentHeight
local rowWidth = row.contentWidth
local textMargin= 72
row.Image = display.newImageRect(row, params.image, 25, 25)
row.Image.anchorX = 0
row.Image.x = sideMargin
row.Image.y = rowHeight/2
row.rowTitle = display.newText(row, params.title, 0, 0, nil, 14, "left")
row.rowTitle:setFillColor(0)
row.rowTitle.anchorX = 0
row.rowTitle.x = textMargin
row.rowTitle.y = rowHeight/2
row:insert(row.Image)
row:insert(row.rowTitle)
end
local function onRowTouch(event)
local row = event.target
local params=event.target.params
--when a row is clicked, it goes to the appropriate page
panel:hide()
composer.removeScene(composer.getSceneName("current"))
composer.gotoScene(params.page)
end
local scrollBarOptions = {
sheet = scrollBarSheet, -- Reference to the image sheet
topFrame = 1, -- Number of the "top" frame

}
-- Table
local tableView = widget.newTableView(
{
left = -((panel.width)/2),
top = -(((panel.height)/2) - menuIdBg.height - 8),
height = panel.height-menuIdBg.height,
width = panel.width,
onRowRender = onRowRender,
onRowTouch = onRowTouch,
listener = scrollListener
}
)
-- Insert rows
for i = 1, #menuRows do
-- Insert a row into the tableView
tableView:insertRow{
rowHeight = 48,
rowColor = { 1, 1, 1},
lineColor = { 1, 1, 1},
params=menuRows[i]
}
end
panel:insert(tableView)

panel:hide()

我会很感激的帮助下，也就是有办法让跟随用户手指的方向菜单吗？谢谢！
