Android Question How to get the Panels from a StdViewPager ?

[klaus]

I would like to get the Panels from a StdViewPager in the code.
How can I do it ?

The StdViewPager is added in the code and GetType returns:
anywheresoftware.b4a.objects.StdActionBar$StdViewPager

Using v = Activity.GetView(0) and GetType(v) returns:
android.support.v4.view.ViewPager

Is there a possibility to get the anywheresoftware.b4a.objects.StdActionBar$StdViewPager object from android.support.v4.view.ViewPager ?

Your question is different and does not belong to this thread. You are asking abot AHViewPager and @klaus is asking about StdViewPager.

You should have created a own new thread for your question.

StdViewPager.Panels returns the array of panels.

StdViewPager.Panels returns the array of panels.

Yes, I know.
But the problem is when you try to get the view with Activity.GetView(x) it returns
this as the type: android.support.v4.view.ViewPager
and not
anywheresoftware.b4a.objects.StdActionBar$StdViewPager

Attached a small project showing the problem.

It is difficult to get StdViewPager from the view directly.

As there is only one StdViewPager then you can always get it from the global variable.

My intention was to add the StdViewPager to the AutoScale Code module.
As I retrieve the different views on the Activity and Panels the global variable is not known there.

I see. You can do something like:
1. When you add the view pager to the activity then set the object to the tag property:

ViewPager.AsView.Tag = ViewPager

2. In the code module you should check the tag value and if it is set you can get the view pager from the tag.

Thank you, but unfortunately it's only a workaround.
A 'lamda' user needs to know this to be able to use it.

This seems to be what I've been trying to do.
Activity.NumberOfViews, svpTest.Panels.Length, vpg.Panels.Length and pnlTest1.Length seem to return the view/panel number.

I'm going to try it with an EditText on 2 layout files (after i take a time out).
btw: the .zip file i downloaded didn't have a Code module.
edit: am trying to use stdViewPager (StdActionBar without the Tabs).

am getting the currentPage number using 'svpTest.CurrentPage' into the log window.

Is this the same as getting the Panels?
