Android News Banner Scrolling effect _android

The project needs to use a similar bulletin board control, can use the basic does not support multi-line display, so had to do their own, suffering from a decent control has not been customized, for reference to the Android bulletin Board demo, to achieve a multiline scroll up control. Add the following functionality on top of the original control:
• Incoming data pagination display
• Add left Drawable
• Finger Touch Event Handling
• Add 3D animation Rollover effect
