I have a viewpager that contains of pages. Both are basically exactly the same, only one is with different drawables. So all I need to do is change the drawables when page two is selected, and change it back when page one is selected. I got this all to work with ONE layout, but I couldn't find out where to change the drawables. This is my code so fare:
private void initViewPager()
{
ViewPager _viewpager = FindViewById<ViewPager>(Resource.Id.viewpager);
_viewpager.Adapter = new FragmentAdapter(SupportFragmentManager);
}
public class FragmentAdapter : FragmentPagerAdapter
{
public FragmentAdapter(Android.Support.V4.App.FragmentManager fm) : base(fm)
{
}
public override int Count
{
get { return 2; }
}
public override Android.Support.V4.App.Fragment GetItem(int position)
{
return new LayoutFragment();
}
}
public class LayoutFragment : Android.Support.V4.App.Fragment
{
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var view = inflater.Inflate(Resource.Layout.Viewpage1, container, false);
return view;
}
}
I'm inflating "Viewpage1". This layout contains my xml that, when page two is selected needs to have changed drawables ( just the image of 6 buttons).
How would I implement that into my code? Thanks.
Follow below steps
1.Create one more fragment like you have done for LayoutFragment. Say NewLayoutFragment
2.Pass your new layout to the newly created fragment.
public class NewLayoutFragment : Android.Support.V4.App.Fragment
{
public override View OnCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
var view = inflater.Inflate(Resource.Layout.Viewpage2, container, false); // Viewpage2 is your new layout file with 6 buttons.
return view;
}
}
3.Put a switch statement in your getItem() method of your Adapter and call the new Fragment instance in the second case. Like this:
public override Android.Support.V4.App.Fragment GetItem(int position)
{
switch(position){
case 0:
return new LayoutFragment();
case 1:
return new NewLayoutFragment(); // this is your new Fragment with new layout.
}
}
I hope this should work. :) Happy coding.
