howdy, Paul!

how can I help you?

Hi Mark.... Im a first time chatter

I have a problem in trying to refresh a ListView after changes Preferences in a Menu

what sort of adapter are you using? and where is the data for that adapter coming from?

The challenge is getting the system to return back to the calling function so that I can get issue the adapter invalidate commands

(I suppose this is going to become a cut and paste situation)

Adapter is a database cursor and the data comes from sqlite3

The function basically allows the user to change a view filter

"view filter"?

so that they can see all items or only a subset

are you changing the database query in response to the preference change?

Yes, see all records, see all completed records

Yes, thats it

easiest thing to do is to associate a new adapter with the ListView, then

you'll see where I do that in Android Programming Tutorials, Tutorial #12

OK... I will have a look at chapter 12

there, I have a PreferenceActivity that lets the user choose a sort order

I use a preference-change listener to find out when they modify the setting

I really like your books... they really helped and I dont think there is any other resource like them available..

Thank you so much for your help.

there are lots of other books, though the whole set you get for the Warescription is tough to beat

happy to help!

hi mark

hello..no one's here yet

actually, Paul just left

how can I help you?

ah..ok..just one question, very basic..i use it most of the time but i dont really understand it

basically the difference between android:gravity and android:layout_gravity

ah

android:gravity controls the placement of things inside a widget

for example, where text goes in a multi-line EditText

android:layout_gravity is an instruction to the widget's container saying where the widget would like to be placed within that container

layout_gravity is mostly used with LinearLayout -- you have better placement options with RelativeLayout, for example

ah, hmm, so lets say i have a linear layout with gravity=center and inside i have a textview with layout_gravity=top

which one takes effect?

beats me

Personally, I'd try to avoid situations like that

normally, where would you suggest to put the layout, on the container or on the widget itself?

"to put the layout"?

i mean, would you put gravity on linear layout, or put layout_gravity on the widget inside the linear layout

I tend to use RelativeLayout

of your two, though, I would probably go with layout_gravity on the widget

alright..

btw, i missed your visit here in singapore..did you do any android-related session?

CodeAndroid hosted a "chillout session" sort of meetup on Monday

oh..right..tsk tsk..missed that one

I'll be in the KL area in a couple of weeks, but I don't know if there is an Android group there

i think there's a CodeAndroid malaysia

you can contact zi yong as well

any plans going to the philippines? the GTUG there is quite active and can help organize

I go where the training takes me, and I have had no training requests from the Philippines

ah..i see

I have sent an email to codeandroid.my to see if there is anything I can do to help them while I am in Petaling Jaya

cool..

the chat period is coming to a close -- any questions?

no more questions..just waiting for others to come in

thanks mark

yeah, well, these chats sometimes draw a crowd, and sometimes they do not

have a pleasant day (or night, in your case)!

yeah..till the next campfire..thanks again
