Android list component

I need an Android SW developer who can help to solve the following tasks: 1)Create a component which shows data as in pinterest android app list(without fixed row height) [login to view URL] This component should be able to get data from Adapter. Maybe it'll needed to create a special adapter for it. The component should work with custom view for items that show image: width fix column width, height: according image scale height and text data height. The component must be able to process with large amounts of data(unlimited amount of elements should be possible, images should be recycle when scroll out of screen) 2) A TestSample application should be created for the component usage. The example should dynamically download a content from the network source during component scrolling. You can use any net source, just to provide me possibility to check it.
