random GridView with Images
<p>I want to create a DayDream for my App and i want a Wall of images but i dont know how to randomize the images.</p>

<p>I want that some images are (2 times) bigger than other images and the other images are around them, all random. Is there a simple way to do this?
The Images are saved dynamically in a ArrayList of ImageViews before they will be loaded into the GridView.</p>

<p>Currently i have a simple Horizontal Layout which gets filled with ImageViews, but this is way too simple and won't fill the complete screen...</p>

<p>I have no point where i could start, any help would be fine!</p>
