What do I have to do - override a LayoutContainer开发者_运维技巧 and implement my own onDraw method?

I'm not very good when it comes to graphics/drawing (in code) so can someone give me some starting ideas on how to implement this?

In general it would be much easier. define a 9-patch that can expand that is the background "bubble" and will serve as the background tot he listviewitem. you could dynamically add views (images, textviews, etc) depending on content, or if your needs are simpler, you could just have a single listviewItem.
