Hi there

This is my silly little project. It’s a View you can place anywhere that will display a Holo-themed animated progress/loading spinning circle thing.

It will look the same and function properly on pretty much all versions of Android. (I actually discovered Android’s ProgressBar after writing this. It has an indeterminate mode for a spinning circle. I think it’s harder to use, and looks ugly by default. I still prefer my library here, but I thought I would mention it here anyway.)

It’s designed to be easy to use. Setup involves 3 easy steps (if you use Eclipse):

1. Download the code from this repo, put it somewhere, and add that as an “Android Project from Existing Code”.
2. In your project properties, add the library project you just added in the “Libraries” section in the “Android” category.
3. There are only 2 steps, sorry.
4. How do I sto

Once you’re set up, just add this anywhere in a layout:

<com.sudomakemeanapp.sudowidget.LoadingImageView
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"/>

You can use it just like any other View. layout_width and layout_height can be anything you want. The image will maintain the proper aspect ratio, and shrink or expand up to the size of the Drawable.

“Advanced” usage

There are few methods to know about in the LoadingImageView class. startLoadingAnimation() and stopLoadingAnimation() are two of them and I named them to be self-documenting. If you can’t figure them out, maybe you shouldn’t use this library!

setImageExpandBeyondDrawableSize(boolean) is another. If you set this to true, then the image will stretch beyond the size of the drawable. It’ll get grainy, but it’ll stretch as big as you want.

setImageSize(int) is the last. It will determine the size of the drawable used for the animation. If you need to fit an animation in a tight space, for example, you’ll probably want to use a smaller drawable. Use the statics in the class to set the size. For example, LoadingImageView.SIZE_LARGE is the default size. It’s simple, you’ll figure it out.

There are also three custom attributes that you can use from XML to customize some of this instead of having to write Java code for it (I don’t know anyone who wants to write more Java code). To set that up, under the xmlns:android in your layout files, add another xml namespace

xmlns:sudo="http://schemas.android.com/apk/res-auto"

Once that is done, you can add the custom attributes like this:

<com.sudomakemeanapp.sudowidget.LoadingImageView
	android:layout_width="fill_parent"
	android:layout_height="fill_parent"
	sudo:liv_startShown="false"
	sudo:liv_expandImageBeyondDrawableSize="true"
	sudo:liv_imageSize="sizeMedium"/>

There are three custom attributes:

• liv_startShown: Determines if the animation is showing upon launch. Defaults to true.
• liv_expandImageBeyondDrawableSize: Determines if the image will expand beyond it’s natural size. Defaults to false.
• liv_imageSize: Determines which size of Drawable is used. Values are sizeLarge, sizeMedium, sizeSmall, and sizeTiny. Defaults to sizeLarge.

I think that’s it. Let me know if I forgot anything. If you have anything to say to me, you can find me on Google+: https://plus.google.com/104570711580136846518
