Hello guys,
I want to create a custom widget.
Basically it is something like a toolBar,
I want to draw a background first, and draw my tool buttons on top of
the background.
However, it doesn't work.
What I did is I overrided the onDraw Function
@Override
protected void onDraw(Canvas canvas)
{
custom draw...
}
But it seems that this function never gets called. I can only see my
tool buttons, but not the background. What should I do?
I have another question about calling the parent function from the
overrided function in java.
suppose I have a function named kkk which overrides the function aaa,
if I want to call aaa from kkk, I wrote:
@Override
protected void kkk()
{
super();
}
The problem is, I want to do something before calling aaa
@Override
protected void kkk()
{
//do something here....
super();
}
But java doesn't allow me to do this, it says that super must be the
first thing inside the function.
So how can I call super() after some other code?
thanks.
