DrawLines on Custom View Canvas by keeping It is invisible

These are following steps , I wanted to perform :
First : On the Activity load, make Custom View Invisible.
Second: Draw Lines on Custom View by keeping it Invisible.
Third : On the checkbox check make that Custom View Visible with Already
drew lines.
The only thing I wanted to know that is this possible in Android that we
can draw on custom view by keeping it invisible? If yes then what If I
will make it Visible , will it retain the previous plot what I have drawn
when it was invisible?
Please suggest me with any example, I am new in Android.
Note: I can't redraw it, after making it visible.
I know the code for making it visible and visible and other basic codes.
please provide me code under the onDraw() function.
