I wanted to create a Navigation bar like drawer that held some custom resources and custom widgets which would allow me to put them using constraint layout but this is not provided by android.
How do people create their custom libraries to do that? For example consider this navigation bar (check time code 1:15), it consists of a custom transformation for it's layout, manages layout overlaps and stuff like that. He gives a source for that here.
Please give me a pointer how is this acheived or what knowledge is required to be able to do this. I'm willing to do my bit of research but I don't know where to start or what is used in achieving this. Is it done using OpenGL ES? Canvas drawings? ANY HELP AT ALL would be greatly appreciated.
