How to swipe xml layouts using ViewPager

Question

I am building an app in which I want to enable swipe. I want to swipe xml layouts but in a single activity. Earlier I tried to put images, it worked. I created an ImageAdapter class that extends PagerAdapter. In instantiateItem, I created a imageView object and set its image resource using setImageResource method. I'm new to android and I got this code from somewhere (i don't remember now). Now, I'm trying to do the same, just instead of images, I want to put layouts. I searched in net, I even got the code which uses Fragment..... But, when I write the code, eclipse says, minimum required sdk is 11. But I want my app to run in GingeBread also. I tried to get a reference to the layout using findViewById. But since I've not kept the required layout in setContentView in main activity, find view by id is returning null. I want a way to get a reference the layout or set the layout in View Pager. Any code to do this or which helps to enable swiping layouts would be useful. But I want it to work on Gingerbread also. Pls tell me, if I need to change my question format. Thanks in advance

Here's what I found for your first question. Its the infinite scrolling. Its a good post here:

Answer 2

For your first question, the Infinite Scrolling, I figured out one solution to it.

Here's how I am doing it:

No looping is required in this case. No matter what your getCount() is.

After setting the adapter, I am setting a setOnPageChangeListener to the view pager like this:

myPager.setOnPageChangeListener(new OnPageChangeListener() {

                @Override
                public void onPageSelected(int position) {
//Define the focused page before your onCreate()..private int focusedPage = 0;
                    focusedPage = position;
                }
                //We don't have to do anything here.
                @Override
                public void onPageScrolled(int arg0, float arg1, int arg2) {
                    // TODO Auto-generated method stub

                }
                //Here's where the magic is. After you reach the end of the page, you can scroll again and it will move your view to page 1 again.
                @Override
                public void onPageScrollStateChanged(int arg0) {

                    myPager.setCurrentItem(0,false);

                }
            });

See if this solution works.. It's working perfect for me. .:D
