In Erel’s example on PreferenceDialog the Options feature displays items in the list (cities list), but the screen shows a small number of items. I tried a few ways to increase the height and width, to no avail
I tried these 2 lines of code with no effect:
B4X: 
prefdialog.mBase.Height =500dip  'no effect and no error
prefdialog.CustomListView1.AsView.Height=500dip  'no effect and no error

Thank you

This is how it looks here:



I wouldn't make it taller however you can do it based on: https://www.b4x.com/android/forum/t...ax-number-of-items-to-show.112181/post-699761

B4X: 
Dim st As B4XSearchTemplate = prefdialog.SearchTemplate
st.MaxNumberOfItemsToShow=15
Dim pane As Panel = st.GetPanel(prefdialog.Dialog)                        'Get the main panel
pane.Height=600dip                                                                          'Set Desired Height
Dim lv As B4XView = st.CustomListView1.AsView             'Get the List View
lv.Height=pane.Height                                                                       'Set Same as Parent
Dim sv As B4XView=lv.GetView(0)                                                      'Get the Scroll View
sv.Height=pane.Height

pane.Height=600dip                                                                          'Set Desired Height
Dim lv As B4XView = st.CustomListView1.AsView             'Get the List View
lv.Height=pane.Height                                                                       'Set Same as Parent
Dim sv As B4XView=lv.GetView(0)                                                      'Get the Scroll View
sv.Height=pane.Height
Why do I need all the above code when I can accomplish the same using one line shown below since we are dealing with a B4XSearchTemplate which is re-sizable.:
B4X: 
st.Resize(400dip,600dip)
