I've been playing with this more today and have got it working but it seems
like a bit of a bodge job. So if anyway has a better more efficient way of
doing this I'd appreciate it.
-------Working code for newFrags()----
private void newFrags()
{
int i = 0;
foreach (String s in countries)
{
FragmentTransaction ft =
this.FragmentManager.BeginTransaction();
MyFragment fragment = new MyFragment(s);
ft.Add(Resource.Id.frag_container, fragment, s);
if (i < (countries.Length - 1))
{ ft.Hide(fragment); }
ft.Commit();
i++;
currFrag = s;
} }
-------------ORIGNAL POST CODE----------
----Partial code of Activity1.cs ------------
Private String currFrag = "";
private FragmentManager fm; //fm = this.FragmentManager; in OnCreate
static readonly string[] countries = new String[] {
"Afghanistan","Albania","Algeria","American Samoa","Andorra",
"Angola","Anguilla","Antarctica","Antigua and
Barbuda","Argentina",
"Armenia","Aruba","Australia","Austria","Azerbaijan" }
//Make new fragments with replace
//This works visually but I cannot access the fragments by their tags
//unless they are the current fragment being shown in frag_container
private void newFrags()
{
foreach (String s in countries)
{
FragmentTransaction ft = this.FragmentManager.BeginTransaction();
MyFragment fragment = new MyFragment(s);
//Replace fragment in container with new fragment MyFragment and
give it tag s
ft.Replace(Resource.Id.frag_container, fragment,s);
ft.Commit();
//Set String currFrag to the tag of the newly set Fragment
currFrag = s;
}
}
//Make new frags using add and hiding the last made one (if available)
//This is how I would like to do it so it loads all needed fragments
//then hides them as the next one is made
private void newFrags()
{
FragmentTransaction ft = this.FragmentManager.BeginTransaction();
foreach (String s in countries)
{
//Check if there was a Fragment already created and hide, if not no
need to hide anything
if (currFrag != "")
{
Fragment f = (Fragment)fm.FindFragmentByTag(currFrag);
ft.Hide(f);
}
MyFragment fragment = new MyFragment(s);
ft.Add(Resource.Id.frag_container, fragment, s);
ft.Commit();
currFrag = tag; // If I leave this in App crashes when I run this
function.
}
}
//How I want to switch fragments. This works and keeps all the previous
contents of the fragments
//and allows me to still change things on the fragments in the background
wtihout them
//needing to be visible by finding them using their tags.
private void switchFrag(string tag)
{
FragmentTransaction ft = this.FragmentManager.BeginTransaction();
ft.Hide(fm.FindFragmentByTag(currFrag));
ft.Show(fm.FindFragmentByTag(tag));
ft.Commit();
}
