Corona SDK-在线上的触摸事件不起作用

Question

I am trying to call touch Listener on line, but it is not working. If I try it on any other display object, it does work.

Simple Example:

local function touchListener(e)
    print("removeLine")
    print("Name: " .. e.target.name)
end

Above is touch listener function.

local line = display.newLine(sceneGroup, 0, 0, 100, 100)         
line:setStrokeColor(1, 0, 0, 1)
line.strokeWidth = 10
line.name = 'line'          
line:addEventListener( "touch", touchListener )

Added listener on line , but never works.

local circle = display.newCircle(sceneGroup, 150, 150, 50)            
circle:setFillColor(0, 1, 0, 1)
circle.name = "circle"
circle:addEventListener( "touch", touchListener )

Added listener on circle , and works perfectly.

Can anyone please suggest, what I am doing wrong with line ?

Answer 1

A single line is a small target to try and touch. Apple suggests that 44 points is the smallest touch target.
