如何与ListView并排创建动态ImageView

Question

This is the effect I am trying to achieve

The number of circles depends on the number of children in the ListView and I cant seem to achieve the same effect by using the background as a line and a circle ImageView for each child.

Answer 1

So I believe in your Adapter, there is a getCounts() functions that is publicly exposed. You can use the getCounts() function to get the number of children in your ListView.

I think its better if you actually just place the imageView as a part of the item that will be a part of your list view. This way you don't have to worry about the number of items and then making that many circles. That's highly inefficient too.
