Android:how to instantiate my custom view with attributeset constructor?

Maybe I don't get what you are doing or why you're doing it, but I find your attempt with the AttributeSet quite complicated I'd suggest you create another constructor like this public CalendarView(Context context, int backgroundRessourceID) { super(context); setBackgroundResource(backgroundRessourceID); } And then instantiate your CalendarView like this CalendarView cv = new CalendarView(this, R.drawable.0_bg); cv. SetLayoutParams(new LayoutParams(LayoutParams. MATCH_PARENT, 30)) Hopefully this solved your issue.

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.
