Custom Carousel component

[curiousgally]

I'm planning to create my first custom component and that would be carousel component to achieve a functionality of this:

Some pointers would be helpful regarding the existing components which could be used and tweaked etc.

thanks.

hi ,

A sample algorithm may help u.

1. Create image objects and add to an arraylist
2. draw a hlayout
2.1. add prev button
2.2. hlayout where the images to be placed ,set the hlayout setanimate members() - for animation
2.3. add next button
2.4 set curved border for this layout
2.5 set background image for this

3. set the no:of images to be shown in each page..(in the example its 3)=pagecount
then you find out the no:of pages by arraylist.size()/no:of images per page=noofPages

4. make the activeLinkIdvariable to 1 --its a pointer variable
5. in prevbutton click,

if(activeLinkId>1){
  clearImageLayout(pageCount * (activeLinkId-1),pageCount * (activeLinkId));
  activeLinkId --;
  setImageLayout(pageCount * (activeLinkId-1), pageCount * activeLinkId);
}

6. on next button click

if(activeLinkId<nofPages){
            clearImageLayout(pageCount * (activeLinkId-1),pageCount * (activeLinkId));
            activeLinkId ++;
            setImageLayout(pageCount * (activeLinkId-1), pageCount * (activeLinkId));
}

the functions
clearImageLayout(int start,int end){
//iterate the arraylist of images ,clear the existing images,
//i mean remove the images from the imagelayout
}

setImageLayout(int start,int end){
//iterate the arraylist of images ,add images to the imagelayout in this range
}

I have implemented this well...
u also try it..
