To assign an observation well to an observation group, you must use the assignment method for observation group assignment. Use the Assign Observation Group (AOG) method for observation group assignment.
Overview
The Assign Observation Group (AOG) method is used to assign observation wells to observation groups. When you assign observation wells to observation groups, you can then link each observation well to a field observation point or field.
Procedure
In the MODFLOW Model Data Manager, right-click any observation well and select Assign Observation Group.
In the Data Management tab, select an observation group.
Select an observation well and click OK.
Additional Information
The Assign Observation Group (AOG) method is available for setting up observations for wells, for example, monitoring wells. You must specify the well to be monitored, and define the observation group for that well. For more information, see Assign Well (AW) Method in Visual MODFLOW.Q:
Delete Fragment in ViewPager
I have a ViewPager in my activity which is a FragmentStatePagerAdapter.
I have a list of elements that is generated dynamically from the database. Every time an element is added to the list, I want to delete the element from the adapter.
I understand that I need to call remove() on the adapter in onDestroyView() and then call destroyItem() on the page.
Is there a simple way to do this in one shot? I don't want to call remove() and then destroyItem() every time a new element is added.
A:
You should use ViewPager.setOffscreenPageLimit() to set the number of fragments that can be saved in the OffscreenPageLimit. The number of saved fragments in the OffscreenPageLimit is the maximum number of fragments that can be retained in the view pager's adapter. When the user reaches the end of the pager view, the pager will jump to the first element of the adapter and the saved fragment(s) will be released.
Here is the explanation about OffscreenPageLimit from the ViewPager:
The default limit is 1, meaning that the pager will retain at most one
"offscreen" fragment at a time. A value greater than 1 means the pager
will retain more than one fragment at a time. A value of 1
