How to create an android image viewer - Part 7 creating custom ImageView
This is part 7 of the android tutorial series about creating an android image viewer using the android local storage framework that was introduced in android lollipop.
For part 7 we will be creating our own custom ImageView. Which is basically our own class which extends from the android ImageView class.
And then we will load the bitmap into our new custom ImageView using the glide image loading library.
The reason for creating our own android custom ImageView class is for attaching listeners such as pinch zoom & scroll.

The previous tutorials were aimed at beginners to android but over time have been getting more complex as the original camera_intent app has developed.
This tutorial series is more aimed towards the intermediate developers thought for those who have been following the previous tutorial series, feel free to watch this android performance series.
Android studio (1.5) is the editor of choice (IDE) for this tutorial series.
This tutorial series is the start of what I expect to be many so I encourage comments and feedback to improve the quality and viewing experience.
