如何创建布局我可以放置任何我想要的地方吗？

I'm designing an app with many images, buttons and textViews strewn across the screen. At the moment I am using the relative layout as it seemed the most flexible of the lot. However were I place my elements and their size is still restricted to being aligned with other elements. Even worse if an element changes size any elements aligned to it will also change size.I'm designing an app with many images, buttons
