Level List

A resource that manages a number of alternate Drawables.

It’s inflated into the LevelListDrawable java object.

You can set the level value of the object with setLevel(int) or an equivalent method.

This will load the image/drawable whose maximum level attribute you have passed in the parameter.

This is my first technical blog post and somebody may wonder why I have chosen such an advanced topic… well I like to write about things as I encounter them, and what I am working on currently is themes and styles. I will be slotting in posts to cover the basics as time allows.

Please note that in this post I use eclipse indigo 3.7 for J2EE, if your environment for android development is not yet set in anyway, you may want to deal with that first and then return.

This is a blog administrated by Bengi Egima. The  aim of the blog is to be an ever available content guide for any one learner and a quick reference source  for the busy developer.
