All I want to do is a horizontal carousel in Android.
If I have 3 screens A B and C then I want my ViewPager to allow me to move like A <-> B, B <-> C, C <->
ViewPager settings:
mViewPager = (ViewPager) findViewById(R.id.view_pager);
mViewPager.setAdapter(new YourPagerAdapter(getSupportFragmentManager()));
//Set the number of pages that should be retained to either side of the current page.
mViewPager.setOffscreenPageLimit(1);
mViewPager.setCurrentItem(50);
FragmentPagerAdapter:
public class YourPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 100;
final int REAL_PAGE_COUNT = 3;
public YourPagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
while (position > REAL_PAGE_COUNT - 1) {
position = position - REAL_PAGE_COUNT ;
}
switch (position) {
case 0:
return FirstFragment.newInstance(position);
case 1:
return SecondFragment.newInstance(position);
case 2:
return ThirdFragment.newInstance(position);
}
return null;
}
@Override
public int getCount() {
return PAGE_COUNT;
}
}
