Re: [android-developers] Re: Question on showing contacts with all numbers
So i checked out the code, which I think you meant, but it seems to be using spinners. My goal is to reach the following in a listActivity, i.e present all the data as a 'flat' sctructure. Is there anyone that can help me out on this one? ContactName number number number ContactName number number ContactName number etc.. etc..

[android-developers] Question on showing contacts with all numbers
Hello, I am struggling on how to display all the contacts and all their phonenumbers in one ListView. Because the persons and their phonenumbers are in two seperate dbase tables I need to do two queries. First one, is to get the user _ID the second one is lookup the phones tabel and based on that _ID get the numbers. Using a Cursor and a ListActivity with a single query is not that difficult, but what to do in this case where I need to do sub queries. I tried building my own datasctructure, but that is to slow and to expensive to do every time. How do I go about this. The end result would look like this, where each number is separately click-able. ContactName number number number ContactName number number ContactName number etc.. etc.. Thank you.

[android-developers] Help with contacts/numbers data to listView.
Does someone know how to get a 'flat' map / list of the contacts and
there phone numbers. I am currently using this to build a datastructure,
so I can display it in a lIstView, which is not really fast. The code
shows that I do two queries. Would it be possible to do this with one
query so that I end up with a just one cursor. The structure ideally
would be:
contact name
number
number
contact name
number
This would then allow me with a custom listView Adapter to display the
data and make the names non clickable.
code
public ListContactInfo getContacts(Context ctx) {
// TODO Auto-generated method stub
String[] projection = new String[] { Contacts.People._ID,
Contacts.People.NAME, Contacts.People.NUMBER };
ContentResolver resolver = ctx.getContentResolver();
Cursor cur = resolver.query(Contacts.People.CONTENT_URI, null,
null, null, Contacts.People.DEFAULT_SORT_ORDER);
String name = start_name_identitiy;
ArrayListContactInfo contacts = new ArrayListContactInfo();
if (cur.getCount() 0) {
while (cur.moveToNext()) {
ContactInfo info = new ContactInfo();
String id = cur.getString(cur.getColumnIndex(People._ID));
String dname =
cur.getString(cur.getColumnIndex(People.DISPLAY_NAME));
info.name = dname;
Cursor pCur =
resolver.query(Contacts.Phones.CONTENT_URI, null,
Contacts.Phones.PERSON_ID + = ?, new String[] { id }, null);
int i = 0;
int pCount = pCur.getCount();
String[] phoneNum = new String[pCount];
String[] phoneType = new String[pCount];
while (pCur.moveToNext()) {
phoneNum[i] =
pCur.getString(pCur.getColumnIndex(Contacts.Phones.NUMBER));
//phoneType[i] =
pCur.getString(pCur.getColumnIndex(Contacts.Phones.TYPE));
if(phoneNum[i] != null) {
// info.numbers.add( dname );
info.numbers.add( phoneNum[i] );
}
i++;
}
if( info.numbers.size() 0 ) contacts.add(info);
}
}
return contacts;
}

Hello, i want to build a list view that shows all the contacts and their phone numbers. I have this working but I don't like the following. If a user has one contact that holds multiple phone number ( home, work etc) the cursor I receive will list every phone number with each duplicate name.

What is the easiest/best/most efficient way to achieve this. I geuss I would have to make custom row layout for a the listview, and then keep in mind that there can be more labels. The big thing I am really not sure on how to do is, how to create the underlayin data structure. Does android already provide a way of getting the data layed-out for me as described?

[android-developers] Question on NotificationManager, setLatestEventInfo() and custom view.
Hello,
I am creating a notification that displayes the progress of downloading
files. Because I use a custom layout to be displyed in the expanded
view. This custom view has a progressbar. I first make a call to the
notification manager that will show the progress bar as being
indeterminate and display a text 2 / 10 for instance.
Then when the downloading starts i only want to update the prgress bar.
code
private void showNotification(String tickertxt, String displayTxt ,
int total , int progress , Boolean indeterminate) {
NotificationManager notifMgr = (NotificationManager)
this.getSystemService(Service.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
new Intent(this, MainMenu.class), 0);
// construct the Notification object.
Notification notif = new Notification();
notif.flags = Notification.FLAG_ONGOING_EVENT |
Notification.FLAG_ONLY_ALERT_ONCE;
notif.tickerText = tickertxt;
notif.icon = R.drawable.icon;
RemoteViews nmView = new RemoteViews( getPackageName(),
R.layout.custom_notification_layout);
nmView.setProgressBar(R.id.progressbar, total, progress,
indeterminate);
nmView.setTextViewText(R.id.TextView01, displayTxt);
notif.contentView = nmView;
notif.contentIntent = contentIntent;
notifMgr.notify(R.layout.custom_notification_layout, notif);
}
/code
So the first call i make when downloads are being prepared is:
showNotification(download... , n / n files , 1 , 1 , false)
then when downloading starts:
showNotification(download... , n / n files , class.getCurrent() ,
class.getTotal() , true)
What is bothering me is that I call the second call quit a lot and thus
in the showNotification() a lot of objects are instantiated. In the docs
it talks about setLatestEventInfo() but this (afaik) cannot be applied
when using a custom view.
Is this the way it is or is there a better technique.

android:layout_height=fill_parent
android:paddingLeft=10dip

ListView android:id=@id/android:list
android:layout_width=fill_parent
android:layout_height=fill_parent
android:background=#22
android:layout_weight=1
android:drawSelectorOnTop=false/

in the onCreate you will have to set:
this.setContentView(R.layout.listview_layout);
This is how I would do it, but i am really a newby, so if anyone has a
better suggestion, lets hope they speak up :)

Can you give an example of when they would not be?
I would, however, like to request that the ListView be enhanced with
two new methods:
voidaddHeaderView(View v, Object data, boolean isSelectable, boolean
scrollsWithContent)
void addFooterView(View v, Object data, boolean isSelectable, boolean
scrollsWithContent)
This would allow a dev to leave management of the headers and footers
entirely with the ListView and provide the ability to have sticky
headers and footers that are owned by the ListView.
What's the advantage of this over putting your headerview above the
ListView
in a LinearLayout?

COuld you maybe use intent.getComponent() and then use the packageManager its getReceiverInfo(componentName); http://developer.android.com/reference/android/content/pm/PackageManager.html#getReceiverInfo(android.content.ComponentName,%20int) Not sure if this is what you need, or if it is the best solution.

For it to be secure, I cannot trust any application to be truthful about the identifying data it is passing into my service. Therefore, I need some system way of identifying who sent the intent in a way that the calling application cannot change that information.

[android-developers] Re: Good practise
Thnx Kaj,
well it is not really an app. I am exploring Android and Java, coming
from an AS3 backgound. I havent even begun to look inot threads.
But to answer your question. The app is just drawing dots to the canvas
and one button is moving them all x+=1. I wanted to find out how to deal
with this in Android.
1. use an intent that all the newly created dots are listenening to.
2. use a model and register this to listen to an intent. When it
responds, it goes through the dots and updates them.

Kaj Bjurman wrote:
You haven't told us how many dots that you have, but I do think it
sounds like an odd design. What kind of application is it? How often
are they moved? How many dots do you have? What do they represent?
I might of course be wrong here, but this sounds a bit like a common
problem that I often see in people who are starting with game
programming and is using e.g. one thread per bullet or what ever
they have that is moving.

The main point is, that being so new, i have to post these kind of

understand your point correctly, it is not bad practice what i did. I
just need to optimize...
Using a dotmanager, isnt it more expensive to go through all the dots an
update them. I can imagine by using the architecture as is and not
implement another structure, this would be faster.
Any ideas on that?

Code first for simplicity then optimize if/as needed. That being said
(well, more like pontificated, sorry), a simpler design would be to
aggregate all your dots into a DotManager. This would listen and draw
all the dots as needed. Aggregation works if all the dots are similar
enough that their code can be centralized, and if I understand your
problem correctly (all dots listen for the same event and then they
all move), my brilliant and royalty-free design would be appropriate.

If it compiles, you do not have a scope problem.
More likely, pView is null. You can determine this by checking the Java

[android-developers] Re: receiver enabled=false , problems after instantiation to set to listen
One more question. In my Activity.onDraw method I have this: Dots dotModel = new Dots(); IntentFilter iFilter = new IntentFilter(); iFilter.addAction(org.dadata.demo.ON_UPDATE); this.registerReceiver(dotModel, iFilter); Then later in a click handler I wrote this: Intent intent = new Intent(); intent.setAction(org.dadata.demo.ON_UPDATE); getApplicationContext().sendBroadcast(intent); Is there some way to externalise the now hardcoded string: org.dadata.demo.ON_UPDATE so i can access it from anywhere and reducing the risk of typed errors?

[android-developers] Re: Good practise
Thanx Yusuf,
your advice is right, i should optimise later. I have to admit i am just
started exploring Java and the android API, so hence the sloppyness.
The main point is, that being so new, i have to post these kind of
questions to take away some insecurity on choices i make. If I
understand your point correctly, it is not bad practice what i did. I
just need to optimize...
Using a dotmanager, isnt it more expensive to go through all the dots an
update them. I can imagine by using the architecture as is and not
implement another structure, this would be faster.
Any ideas on that?
Jiri
Yusuf T. Mobile wrote:
Code first for simplicity then optimize if/as needed. That being said
(well, more like pontificated, sorry), a simpler design would be to
aggregate all your dots into a DotManager. This would listen and draw
all the dots as needed. Aggregation works if all the dots are similar
enough that their code can be centralized, and if I understand your
problem correctly (all dots listen for the same event and then they
all move), my brilliant and royalty-free design would be appropriate.

I was wondering if the following is considered good practice.
I am creating mulitple Dot instance. A Dot instance is a value object
containing x,y, color, diameter fields.
I draw each created Dot to a view:
code
canvas.drawCircle( dot.getX(),dot.getY(),dot.getDiameter
(),paint);
/code
Now i want all the Dots to listen to a certain event, lets say that i
want to click a button and move all the Dots.
What i do is in the Dot constructor i add this code:
code
IntentFilter intentFilter = new IntentFilter
(org.dadata.demo.SEND_TO_REACTOR);
Appcontext.registerReceiver(this, intentFilter);
...
@Override
public void onReceive(Context context, Intent intent) {
this.x += 5;
}
/code
Then from my button i send the intent :
code
intent.setAction(org.dadata.demo.SEND_TO_REACTOR);
getApplicationContext().sendBroadcast(intent);
View.invalidate();
/code
I am wondering if someone could give me some feedback on this. Is it
expensive for instance, and are there better ways to achive the same.
Thank you,
Jiri

[android-developers] Re: Widget design in Gimp
I have been facing the same problem. First I wanted to create my own widget background but then I have downloaded one of the examples of the background from this site (http://developer.android.com/guide/ practices/ui_guidelines/widget_design.html). Then I have used the draw9patch utility (part of the Android SDK - http://developer.android.com/guide/developing/tools/draw9patch.html) to allow stretch the picture in any different size with correct proportion. Using this utility you don't have to have precise size of the background image because it will be resized as required. This way, I have got the same look and feel of the widget background what original Google widgets have.

[android-developers] How to refresh ListView?
Hello,
I'm facing to one problem with ListView. I would like to refresh the
ListView every time I change the base data. Please see the following
example:
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapterObject(this,
android.R.layout.simple_list_item_1, mStrings));
new Timer().scheduleAtFixedRate(new TimerTask() {
public void run() {
Log.d(TAG, running timer: num= + num);
mStrings[0] = Unpdate + num;
num++;
/** refresh the ListView - HOW??? **/
//TestList.this.getListView().invalidateViews();
//TestList.this.getListView().refreshDrawableState();
// what else???
}
}, 5000, 2000);
}
Can somebody give me a hint how to implement this feature?
Best regards,
Jiri

[android-developers] Shipping a European dev phone to the US?
I'm interested in buying the Android Dev Phone 1, which I'd mainly use in Finland and elsewhere in Europe. This means that I'd need to get the version that uses the Finnish GSM and UMTS band, and of course comes with a 230V charger. I'll be visiting the US over the holidays, so it'd be very convenient (read: probably faster and cheaper) for me to get the phone shipped to a friend's place and pick it up from there. So my question is, is it possible to get the European version of the phone shipped to an US address?
