[android-beginners] Re: Key Value pair in a spinner
Hi Alex,
It sounds like you might be making a simple thing complicated. You
want to use two parallel arrays, one array for the keys that display
in the spinner and the second array for the numerical values when one
of the keys is selected. Put the keys and values in the correct order
so the index will match up. Maybe I misunderstand but it seems like a
straightforward case where you can access the correct value by reading
the position from the spinner key when there is a click event on the
spinner.
With regards to your request for information on layouts... I found
this web page with a bunch of the layouts from Android 1.5 to be very
helpful:
http://svn.jetbrains.org/idea/BRANCHES/MaiaM1/bundled/android/testData/sdk1.5/platforms/android-1.5/data/res/layout/
Regards,
Beth

I haven't tried using the spinner adapter yet, so I'm not sure, but it might
be possible to do the following:
- Create a new object that holds both the city string and the number
- Override the toString() method to return the city string
- Pass the array of your new object type to the spinner
- Then the spinner would return your object and you can get the number value
from that
Again, I don't know how the spinner adapter is set up exactly, but you might
be able to get something like this to work.
Hope that helps,

Hey, I was wondering how to put a string array in a spinner (I can,

But it seems that there's no constructors for that (I may be
mistaken).
I have 2 arrays: {5123, 7434, 7333, 7345 } and {City 1,
City 2, City 3, City 4 }. Obviously, the spinner UI should show
the name array of the cities, but in the backend (what's returned from
the submission of the form is the value.
Anyone knows how?
// Put the array in the spinner
ArrayAdapterString adapter = new ArrayAdapterString(this,
android.R.layout.simple_spinner_item, cityNames);
spinCities.setAdapter(adapter);
While, I'm the subject of spinners: is there any resource on the
internet describing every type of spinner layouts? I'm using
simple_spinner_item but I find it too small. Any suggestions?
Thanks.

[android-beginners] Re: How to redraw the list in ExpandableListViewActivity
Hello again! Please allow me to rephrase the question.
I have an expandable list view with a static array for the group data
and an SQLite database for the child data. It is implemented with the
BaseExpandableListAdapter and works great, except, when I edit the
database to delete or add children to the list I do not see the
changes onscreen. It looks like I can use the registerDataSetObserver
method to notifiy the adapter and expandable list of a data change.
What I might do in the callback to redraw the list when the data
changes is an unknown.
Can anyone offer advice on how to use a DataSetObserver?
Documentation on this part of the SDK is a bit sparse and expandable
list view example code is not a good match. It feels like I have to
switch over to a Cursor type adapter. Any insight is most welcome.
Pardon the double post to Android Dev.
Best regards,
Beth

The constructor for the list adapter is where I execute the code to populate
the groups and children. Do I want to drop and create a new list adapter?
That seems like a waste of perfectly good rows. Is it something I should do
in the ExpandableListViewActivity, rather than the TabHost? The fact that
this is an expandable list is probably irrelevant; I am stuck where an
object on the screen that has changed is not redrawn automatically.
Your help is deeply appreciated.

[android-beginners] Re: SQL Lite question, can you insert negative numbers (ExpandableListView help needed)
Thanks Mark, content values work great. I am hoping for a few more examples or some direction from the experts today. I want to get sqlite data into an expandable list view (activity). After combing through the user groups and looking at docs and sample code, I find nothing that shows a SimpleCursorTreeAdapter for ELV holding data from sqlite. It looks like this adapter is intended for use with the OTHER cursor, the one holding data returned from a content provider query. Should I be using a different adapter for sqlite data?

Re: Fwd: [android-beginners] Alarm Manager
I hit this issue hard and found the answers sorting through threads on the non-beginner developer group. Here is what I learned... When setting more than one timer/alarm, the second parameter in the Pending Intent call to getBroadcast is important. Your code looks like this: PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, i, 0); The first zero can be changed up. At this point, the docs define the second parameter this way: requestCode Private request code for the sender (currently not used). However, this request code can be used. If you want to setup a bunch of timers/alarm calls, try using unique request codes for each individual alarm. Track these request codes and set them to be the same when you want to update or cancel an existing alarm. Although the docs say that system is supposed to recognize the intent parameter and take action based on matching the intent and the flags in the last parameter, I found that the request code was used in the match-up. Setting unique request codes for each unique intent solved all my problems. World peace will ensue.

method is executing the code inside my if. Here's some code I tried:
if (prefs.getBoolean(ctxt.getString(R.string.led), false)) {
//notification.defaults |= Notification.DEFAULT_LIGHTS;
// when default did not work I tried these settings
notification.ledARGB = 0xff00ff00;
notification.ledOnMS = 3000;
notification.ledOffMS = 1000;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
}
If you have it going can you send me a snippet with your working settings?
Thanks and regards,
Beth

[android-beginners] Layout component width measure returns zero from onCreate
Hi there, Can a layout expert offer insight here? I have an animation in a lovely LinearLayout ViewGroup object that I get into Java from the XML using findViewById. It's working great most of the time. However, my first call to the animate function at the end of onCreate measures the width of this ViewGroup to be zero. What am I missing? The same object will return correct width measurements later in the thread of execution. How can I get the correct measure from onCreate? Because of this behavior I have hard-coded values into my application for the Center X which might work nicely on the current HTC devices and then blow up later, or it might look bad in Europe on devices with different screen sizes. I tried a number of things to solve this (force layout, varied animation cache persistence, getMeasuredWidth instead of getWidth, invalidate on the ViewGroup and parent). The layout and the component's measurements should be the same for onCreate as it is in another method in the Activity that responds to touch input from the user. Also note that if I navigate in the app to another activity, change orientation, and then return to the first activity, this scenario also causes the ViewGroup's getWidth command to be zero. That is why I assume the issue is related to onCreate. How do I get the correct measure of a (linearlayout) component when executing from onCreate? Is there something in the window's drawing sequence that I need to workaround? Any tips or suggestions are most welcome.

[android-beginners] Re: PreferenceActivity, using the built-ins with style
OK, so I found one answer... In the docs, there is a Note: to refer to a value in the currently applied theme, use ? instead of @ However, I still need helping getting Android to find my style in the layout tag. Anybody?

[android-beginners] PreferenceActivity, can a checkbox and a checkbox preference share?
In a tabbed view, I have two activities where I want to display the
same preference. One tab is a preference activity and the other is an
ordinary activity. Although this seems straightforward, the screens
are not staying in sync.
When I modify the checkbox in the ordinary activity tab, I fetch the
shared preference with the Checkbox Preference key and edit the value
as needed, committing the change to Shared Preferences (code pasted
below). The PreferencesActivity should display the shared preference
value and does not seem to get the update.
The reverse is also true. If I set the preference in the preferences
activity, my regular activity should read the update and display the
checkbox to match the preference screen. Maybe a view of the activity
is cached. Does that explain both cases? How do I ask the system to
redraw the tab rather than use a cached view?
Here are snippets, for clarity in my description:
From the ordinary activity -
if(mPreferences.getBoolean(getString(R.string.sch_enabled), false)) {
enabled.setChecked(true);
other stuff to do
} //no else clause included
public void onCheckedChanged(CompoundButton buttonView, boolean
isChecked) {
if (isChecked) {
//code to handle enabling through the scheduler
checkbox
mEditor.putBoolean(getString(R.string.sch_enabled), true);
mEditor.commit();
} else {
mEditor.putBoolean(getString(R.string.sch_enabled), false);
mEditor.commit();
}
} //other code not included
From preferences.xml:
CheckBoxPreference android:key=@string/sch_enabled
android:title=@string/enable_cb
android:summary=@string/sched_desc
android:defaultValue=false
android:layout_width=wrap_content
android:layout_height=wrap_content /
If anybody has dealt with this, I sure would appreciate a tip.
Best regards,
Beth

[android-beginners] MODIFY_AUDIO_SETTINGS permission
Hello there, I first wrote to the android developer group about this and I got no responses. Has anybody successfully set the MODIFY_AUDIO_SETTINGS use permission? I try to set it and get a permission exception with every run of my application. Thanks for any insight you might have.
