Drawing a graph, can not see the resulting image?

I had a similar problem once, and I was told that what erarchy viewer does is a requestLayout() So, I was told, I probably forgot to call it somewhere, but I don't think I did. Later I've found that a similar situation was reported as a bug, being a workaround finding the way to call requestLayout() somewhere It was strange because actually at some conditions the thing worked (adding some random view here and there, or updating the drawing). Anyway, at the end I preferred creating a custom view that simply directly drew what I needed (and as drawing happens after onMeasure, there's no problem in making an adaptive drawing) (funny it's again about graphs!) references (1) and (2).

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
