howdy, Suzanne!

hallo (again) got your chapter on fragments

have a question about your comment on same fragments for different orientations

OK

is there any workaround?

hmmm...thought I covered that somewhat

the best workaround is a FragmentTransaction

but that's a bit beyond what I want to cover in that chapter

I'll be covering it in the Advanced Android book shortly

ok, i've only read through page 389 .. sorry

is it possible to tap a fragment, or ui control in a fragment, and show or hide it?

lacking that, the next-best workaround is to make the unnecessary fragment's view gone, which is what I'm doing in EU4You_6

you can't hide a fragment, but you can hide its View

which amounts to the same thing from a UI standpoint, AFAICT

yes

again, FragmentTranscation is the right way to accomplish it

and EU4You_6 does that already? please excuse that I didn't finish the chapter yet

EU4You_6 takes the hide-the-unnecessary-fragment's-view approach

(btw, howdy NetApex and fitz!)

Hey there Mark

ok. I'll go back and look more

hello

I am sure that there are gaps that I need to close in that chapter, so I am certainly up for suggestions

okay. will finish it on the plane tomorrow, and lyk

NetApex: do you have a question?

Working with an array... kicking my butt trying to get the view correctly

I have a runnable and when the array gets the data from the Internet and tries to update the view it can't because it is not the main ui

I am trying to figure out how to set the adapter correctly basically

personally, I'd use an AsyncTask, with the background work in doInBackground() and the adapter-update in onPostExecute()

if you want to stick with your existing code, just wrap your adapter-update logic in a Runnable and call post() on some View

or runOnUiThread() on your activity

does AsyncTask give you the option of showing a progress indicator of some sort?

sure

doInBackground() can call publishProgress()

Ok then that is the direction I shall head

that routes to your onProgressUpdate() method on the AsyncTask

which is called on the main application thread

Ahh ok cool

I have examples of it in the threading and rotation chapters of The BCG to Android Development.

fitz: do you have a question?

na just getting more coffee so I can concentrate on topics :)

OK

been a LOOOOONNNNGGGGG day

Suzanne: got another question?

OK, if anyone has a question, chime in

I have another related question then

go right ahead

ArrayList.. where do I make a change in the spacing of the lines?

ArrayList doesn't have lines

do you mean the rows created by your ArrayAdapter?

Err, yeah sorry about that

I think there's an attribute on TextView, hold on...

android:lineSpacingExtra

or android:lineSpacingMultiplier

Is there by chance a "word wrap" type function too?

that's built in

it automatically wraps

Hmm, okay cool

you may need to adjust android:minLines, android:maxLines, or android:lines to suit

Ok

That gives me plenty to start from

welcome back, Suzanne!

thanks

I just came back to say .. it does, I found it

sorry I didn't see it sooner :-)

what does what?

EU4You detects orientation and hides a view

ah, yes

I'm just moving too fast these days

nah, that's just the jet lag talking

okay. we'll tweet you from berlin and london

thanks!

danke, and see you soon :-)

So, Google I/O, are you going?

scheduled to, yes

Cool, I want to get the chance to shake your hand for the helo!

err.. help

that could be challenging, with ~8,000 attendees

I|O isn't CES, but it's still a pretty big crowd

Hehe, yeah... just look for the Android fan lol

again, if anyone comes up with a question, just ask

Alright, so I have adapter that I want to post end layout...

"post end layout"?

Where do I place that part of the code?

on the main application thread

(man, I am typing bad tonight)

so, if you're using an AsyncTask, that feels like onPostExecute()

so I have to pass the items to the onPostExecute() call then?

well, onPostExecute() needs them somehow

option #1: return the items from doInBackground(), and get them as a parameter to onPostExecute()

option #2: put the items in a data member of the AsyncTask in doInBackground(), then access the data member in onPostExecute()

option #3: just generate random garbage for the data in onPostExecute() and hope the user doesn't notice

:-)

lol

seems option #2 might be the one I will shoot for

Essentially, I will be gathering post from a site and enabling a mobile view, so having something local and possibly in a sql stae may be good

"a sql stae"?

dear lord!! sql state

you really need to cut back on the bourbon when you're on these chats... :-)

I have been limiting myself to two bottles lol

if your data is in a SQLite database, rather than converting the data into objects in an ArrayList, you might consider just using a CursorAdapter or SimpleCursorAdapter

well currently it isn't, but I had thought of placing it into one just in case the user doesn't always have a network connection

depending on the data format, it may be simpler just to cache the downloaded file, rather than fuss with pouring it into a database

it all really depends on what you're trying to do

Hmmm, interesting idea

It's only post from a website, to title, an occasional image, and some text

you're downloading this as... HMTL?

er, HTML?

no, json

oh, yeah, I'd seriously consider just hanging onto the file

ok I will take that advice

assuming the objective isn't for the user to modify the data offline, for something that small, parsing the JSON probably won't be any slower than querying a database, and it can simplify your code by not bothering with SQLite

I am all for simple code

ok thanks, I will get started, thanks!

cya

any last questions?

ok, that's a wrap then

two more chats next week

have a pleasant day!
