FAQ
- We know how to animate widgets now, but what about shapes or images that I create myself?
ImageView
can hold any image you like. Just add the image to thedrawable
folder and then set the appropriatesrc
property on theImageView
. You can then animate whatever image is being shown in theImageView
widget. - What if I want more flexibility than this, more like a drawing app or even a game?
To implement this kind of functionality, you will need to learn another general computing concept (threads) as well as some more Android classes (such as
Paint
,Canvas
, andSurfaceView
). You will learn how to draw anything from a single pixel to shapes, and then how to move them around the screen in Chapter 28, Threads, Touches, Drawing, and a Simple Game.
