howdy, Kevin!

Hi there

how can I help you today?

I'm trying to understand the Honeycomb Fragments

yeah, I haven't dived into them too much yet

been waiting on the backwards-compatibility library Ms. Hackborn and others are working on

I figure I better learn it

I'm trying to build an app piece by piece to make sure I understand it

what specific questions do you have about them?

A couple of items:

I'm using Intellij and it doesn't recognize "fragment" in the xml file. Why is it lower case?

(it compiles ok)

I think they use lowercase for things that aren't Views (e.g., <merge>)

as to why IntelliJ IDEA does not recognize it, they're probably not up to speed on Android 3.0 yet

I've got a list fragment and an edittext in another xml file. The edit text doesn't show up

have you used hierarchyviewer to track down the EditText?

No. How do I start that?

if you're using IDEA, I think you'll have to use the command-line -- there is hierarchyviewer in your SDK's tools/ directory

it's also possible that you will need to close down IDEA when you are doing this check -- not sure of IDEA and hierarchyviewer will fight over access to the debugging port

It came up with a text view of the emulator

I don't understand -- what is "it" and what is "a text view of the emulator"/

Never mind. It just hand a list of programs

Got it now

I cover hierarchyviewer in _The Busy Coder's Guide to Android Development_, in the tools chapter towards the back

Yes, it should list "windows", which roughly equates to "processes with an activity in RAM"

Ok. The editText is there. Probably just doesn't have anything to show.

I noticed a new version of your book

yeah, hierarchyviewer will show you width, height, X/Y position, and stuff

yes, 3.5 was released on Saturday

starts in on Honeycomb coverage, mostly action bar

Cool. Just what I need

howdy, Julius!

hi

Julius: do you have a question?

yeah

Uh currently I have no xml resource defined for my menu items

if I wanted to Honeycombise my menus (into the Action bar) do I need to create these? (I'm guesisng I do looking at your documentation)

no, MenuItem has relevant methods

setShowAsAction() equates to android:showAsAction

but they might not be available for older versions of the AIP?

AIP

setActionView() equates to android:actionView

API

no, they definitely are not

using XML resources means you don't have to worry about it too much

it seems like the xml is backwards compatible

though

right

cool

if you want to stick to Java, you will need to do tricks like I document to isolate the API Level 11 code

yeah that seems to be the next thing for using push

er c2dm

(for me)

thanks

Calvin: do you have a question?

yes a UI one

(thanks for the update - really great!)

I have a spinner and ListView on an activity

and I am able to populate both

but then the spinner.setAdapter(aa) code

would empty the ListView

sorry for being sparse but do you need more info?

you cannot simultaneously use the same adapter for a ListView and a Spinner

and, you cannot simultaneously use the same Cursor for two different CursorAdapters

they are different adapters

are they CursorAdapters on the same Cursor?

custom adapters

sub class ArrayAdapter

with ArrayList of Custom objects as data source

are both adapters using the same ArrayList? I would not expect that to be a problem, but perhaps it is

also the spinner and listviews are on TabHost

lemme check that

so the adapters are using different ArrayLists

sorry No the adapters are using dirrent ArrayLists

I have no idea why calling setAdapter() on a Spinner for one ArrayAdapter on one ArrayList would affect a ListView set up for a completely different ArrayAdapter on a completely different ArrayList

k

sorry

np

Kevin: do you have another question?

got to be in it to win it

thanks for the time

have a good night
