Although Android system has a very good built-in drag & drop mechanism, I seeing lots of libraries that just duplicate this behaviour, or users that hack they way for building drag & drop on their apps. In this blog post I will explain how to implement a simple drag & drop functionality between different views with a very small amount of code.

In part 1 we learned how to build a simple custom view that’s integrate nicely with our pager view and show some indication about the current page, in this post we’ll take the view to the next level and add some subviews for page headers

Until couple of months ago I’ve been a bit afraid writing custom views. I thought it’s too complicated and had a lot of overhead with handling all layouting and interactions, I felt there is not enough documentation out there, not mention the edge cases and performance. I had my default Android view component in my toolbox and thought that everything I needed can be composed from those.

I started developing for Android 3 years ago. I was never really formally taught - no ‘real’ classes, no online courses. I did what I usually doing when I’m trying to learn a new thing - figure things out through trial and error. I downloaded the SDK and started tweaking and playing with things around while reading the Android developer guide.

A few days ago I’ve struggling with some bug someone reported about one my apps- ripples.
