bubblebutton.Clicked += Bubblebutton_Clicked;
}

Welcome to SO !
If using Button inside Item of ListView , should use the MVVM architecture to do . That means we should use Binding model to get the click event .
Such as modified code as follow :
```
<AbsoluteLayout >
<ImageButton x:Name="bubblebutton"
BackgroundColor="Transparent"
Source="st_fab_button.png"
AbsoluteLayout.LayoutBounds="3,500,700,80"
Command="{Binding MyCommand}"
IsEnabled="True"
/>
</AbsoluteLayout>
```
Then in your ViewModle should declare the MyCommand :
public ICommand MyCommand { private set; get; }
public ViewModel()
{
MyCommand = new Command(
execute: () =>
{
// do some thing
RefreshCanExecutes();
},
canExecute: () =>
{
// return !IsEditing;
});
···
}
In addition , you also can pass Parameters , more info can have a look at this document .
