Replacing A Fragment In A View Pager

I am trying find a solution simular this https://stackoverflow.com/a/13925130/1634451 but the poster didn't explain what R.id.products_list_linear is. I tried to set R.id.products_

Solution 1:

Replace Fragments Within a View Pager

Try this customized ViewPager Adapter,..

import java.util.List;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentStatePagerAdapter;
import android.view.ViewGroup;

publicclassViewPagerAdapterextendsFragmentStatePagerAdapter {
    privateList<Fragment> fragments=null;
privateFragmentManager fragmentManager=null;

publicViewPagerAdapter(FragmentManager fragmentManager,List<Fragment> fragments) {
    super(fragmentManager);
    this.fragments=fragments;
    this.fragmentManager=fragmentManager;
}
@OverridepublicFragmentgetItem(int position) {
    return fragments.get(position);
}
@Overridepublic int getCount() {
    return fragments.size();
}
@OverridepublicvoidsetPrimaryItem(ViewGroup container, int position, Objectobject)
{
    super.setPrimaryItem(container,0,object);
}
@OverridepublicvoidnotifyDataSetChanged()
{
    super.notifyDataSetChanged();
}
@OverridepublicvoiddestroyItem(ViewGroup collection, int position, Object view) {
    fragmentManager.executePendingTransactions();
    fragmentManager.saveFragmentInstanceState(fragments.get(position));
}
publicvoidreplaceItem(int position,Fragment fragment)
{
    fragments.set(position, fragment);
    this.notifyDataSetChanged();
}
}

call it from activity with fragment as arguments,

List<Fragment> fragments = new Vector<Fragment>();
fragments.add(Fragment.instantiate(this, Fragment1.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment2.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment3.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment4.class.getName()));
fragments.add(Fragment.instantiate(this, Fragment5.class.getName()));
mPagerAdapter=new ViewPagerAdapter(getFragmentManager(), fragments);

When you replace view/fragment inside of viewPager then use,

mPagerAdapter.replaceItem(2,Fragment.instantiate(this, Fragment5.class.getName()));

Solution 2:

I ended up going with a different approach that worked out nicely for me. I used a ViewSwitcher for the fragment in the viewpager.
