seems to work fine Override get_context_data function in the IndexView. And there you can send objects more than one.
class IndexView(generic.ListView):
  template_name = 'expcore/index.html'
  model = Activity
  context_object_name = 'activities_list'
  queryset = Activity.objects.all()

  def get_context_data(self, **kwargs):
    context = super(IndexView, self).get_context_data(**kwargs)
    context['interviews_list'] = Interview.objects.all()
    return context
{% for activity in activities_list %}
{% endfor %}
{% for interview in interviews_list %}
{% endfor %}

How do I set an empty view for ListViews in an activity with multiple ListViews?


Tag : android , By : quicky
Date : March 29 2020, 07:55 AM
To fix the issue you can do My bad, this was pretty silly on my part :P I was under the rather ludicrous impression that if I put a TextView somewhere randomly in the xml layout and then set it as the empty view for a list, it would magically disappear and then reappear in the list when the list was empty. I guess I thought that the list would add it as a row in the list when it's adapter was empty. In the unlikely even that someone else decides to try something similarly ludicrous and wonders what's going on, I will post the full version of my original layout as well as the solution.
The code I used to set the empty view was the standard:
mListView.setEmptyView(findViewById(R.id.empty));
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<LinearLayout android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="200sp"
    >
    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#FFFFFF"
        android:text="@string/drafts"
        />
    <ListView android:id="@+id/drafts"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:minHeight="60sp"
        />
    <TextView android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:background="#FFFFFF"
        android:text="@string/finished"
        />
    <ListView android:id="@+id/finished"
        android:layout_width="fill_parent"
        android:layout_height="60px"
        android:minHeight="60px"
        />
    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#FFFFFF"
        android:text="@string/uploaded"
        />
    <ListView android:id="@+id/uploaded"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:minHeight="60sp"
        />
    <TextView
        android:id="@+id/empty"
        android:text="DUDE WHERE'S MY CAR?"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
/>
</LinearLayout>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"

        android:layout_height="wrap_content"
        android:background="#FFFFFF"
        android:text="@string/drafts"
        />
    <ListView android:id="@+id/drafts"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        />
    <TextView android:layout_width="wrap_content"
        android:layout_height="fill_parent"
        android:background="#FFFFFF"
        android:text="@string/finished"
        />
    <ListView android:id="@+id/finished"
        android:layout_width="fill_parent"
        android:layout_height="60px"
        android:minHeight="60px"
        />
    <TextView
        android:id="@+id/empty"
        android:text="DUDE WHERE'S MY CAR?"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center"
    />
    <TextView android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="#FFFFFF"
        android:text="@string/uploaded"
        />
    <ListView android:id="@+id/uploaded"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        />

</LinearLayout>

Changing one ListViews style affects other ListViews also

I hope this helps . Since your Style doesn't have an x:Key attribute, it is applied to all ListBox elements that are in scope. This is called implicit data templating.
If you only want to apply the Style to a single ListView, you should give the Style an x:Key:
<Style x:Key="myStyle" TargetType="{x:Type ListView}" BasedOn="{StaticResource ListViewStyle}">
<ListView x:Name="original" Style="{StaticResource myStyle}" ... />

ItemsControl of ListViews, bind SelectedItem from each ListView where the amount of ListViews are dynamic, MVVM

seems to work fine I would solve it in your Model. Your datacontext seems to be a class with a property Items of type ObservableCollection and your class MyItem then as a property ItemsSubList of type ObservableCollection. Is that right?
The datacontext of your ListView is the instance of type MyItem. You can add a Property SelectedSubItem to your class MyItem and bind it with Two-way-binding to your listbox.SelectedItem.
