Android :: Loading A Large List Of Contacts Into A ListAdapter - Making It Responsive

Jan 23, 2009

I need to load Contacts.Phones.CONTENT_URI and Contacts.ContactMethods.CONTENT_EMAIL_URI into a ListActivity.

Since these are separate Content URIs, I have two separate cursors and can't construct a SimpleCursorAdapter for use in the ListActivity.

The problem is that I have more than a thousand records for CONTENT_EMAIL_URI, which were automatically loaded by GMail. The app becomes unresponsive and Android prompts to kill the app or wait.

Is there a way to make the ListActivity content load in the background, like, by writing a custom implementation of android.widget.Adapter?

Or is it more feasible to use a single cursor, by manually running the SQL query on the contacts tables?

Android :: Binding List Views To Large Data Sets

Feb 1, 2010

I need to be able to scroll through a list with (up to) 20K rows, backed by a cursor on a read-only db. Testing 20K rows on a G1, the query takes approx .02s regardless of table size, while binding the adapter to the list takes 4.5s. Note that this is before the view calls used in rendering. What makes the binding delay more troublesome is that it blocks the UI thread, and is incurred on every rotate. Combine these, and doing a rotate just after starting the bind results in a delay up to 9s.

I tried lazy loading with a base adapter, but that hits the same delay in the underlying cursor.getCount(), and the overall user experience isn't ideal. I also considered using an ArrayAdapter, adding synthesized objects from the cursor rows, but then I'd incur the overhead of creating up to 20K objects (not to mention the additional memory requirements).

Android :: Loading - Row At The End Of The List - During Data Download

Aug 1, 2010

I have got list that is filled with data from internet.

Datas are downloaded in chunks. At the end of the list next portion of data is downloaded and added to the list.

I'm detecting list end with help of onScrollListner:

CODE:........

I would like to addLoading... row when datas are being downloaded. Something similar to Gmail loading row at the end of the list.

I know that I can hack adapter.getCount() to return size + 1 and force adapter.getView to display loading... at the end of the list.

How can I do that in more elegant way?

Android :: Making List Items Of Book Previews Custom Implementation

Aug 19, 2010

I have used RelativeLayout for a custom implementation of a ListAdapter and I am not sure if I can continue using this or if I need to use TableLayout. In the first example I have the text positioned as I would like by using one image view and one text view containing the book name and the author name. However, I want to style the author text differently so I think I will need two text views. In the second example I have added another text view but it floats to the right. Second eg is Clipboard02.png. How can I make the second text view go under the first text (as in eg 1). I have done this in code rather than using XML layout.
http://carriehall.co.uk/Clipboard01.png

LinearLayout.LayoutParams skyParams = new LinearLayout.LayoutParams( 70, LayoutParams.WRAP_CONTENT );
ImageView skyControl = new ImageView( context );
skyControl.setImageResource( R.drawable.the_eyre_affair );
addView( skyControl, skyParams );
LinearLayout.LayoutParams bookParams = new LinearLayout.LayoutParams( LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
bookParams.setMargins( 5, 10, 5, 10 );
TextView bookControl = new TextView( context );
bookControl.setTextAppearance( context, R.style.SpecialText );
bookControl.setText( book.getTitle( ) + "
" + book.getAuthor( )); addView( bookControl, bookParams );

Android :: Loading String Values From File Instead Of List In Class

Nov 1, 2010

I think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);

The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};

What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:

private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.

I'm a bit new to Java, Android, and development in general.

Android :: Loading Dictionary For Input Method Suggestion List

For various reasons, i'm trying to write my own input keyboard. So far all is going well except that of creating the suggestions.

I've found the latinIME algorithm, which is all good.

However i'm having major difficulty working out how to load the dictionary in the first place.

I've had a good look round the net, and found various suggestions, but no definitive answers, and i cant seem to get any of them to work.

If anyone has any suggestions on how best to do it, or even better some sample code, that would be brilliant.

Android :: Custom Contacts Field With A Set List Of Values And Contacts Lookup Performance

May 28, 2010

I'm pretty sure it's not viable to do what I'd like to based on some initial research, but I figured it couldn't hurt to ask the community of experts here in case someone knows a way.

I'd like to create a custom field for contacts that the user is able to edit from the main Contacts app; however, the user should only be allowed to select from a list of four specific values. A short list of string values would be ideal, but an int with a min/max range would suffice.

I'm interested in knowing if it's possible either way, but also wondering if it make sense to go this route performance wise. More specifically, would it be better to look up a contact (based on a phone number) each time a call or SMS message is received or better to store my own set of data (consisting of name, numbers, and the custom field) and just syncing contact info in a thread every so often? Or syncing contacts the first time the app is run and then registering for changes using ContentObserver?

Android :: Filter Out Contacts From Contacts Pick List / Create New Contact

Aug 19, 2009

My application wants a functionality of picking a contact from the phone contact, I have achieved this using the following intent Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); startActivity ForResult(intent, 001); I wanted few more functionalities
- An option to create a new contact from the pick list, similar to the one which is available in inbuilt Launcher appliation
- Set of contacts should be filtered from display i.e already selected contacts should not be displayed
- Filtering of contacts should be based on the phone number i.e a contact might have two phone numbers associated with and wants to filter out the phone number which is selected I guess above can be achieved by implementing my own pick list using contacts provider, is there any other way without implementing the new pick list

Motorola Droid :: Making Quick Calls To Certain Contacts When On Road

Nov 16, 2009

I know, I know, don't use your phone and drive, but you know, sometimes you have to. I find the droid kinda tricky to power on, unlock, then call a certain contact. There are way too many screens to go through, even with contact shortcuts right on my home desktop. What are your tips and tricks for making this process easier? I like the "voice dial" app and I wish I could tie that to one of the hard buttons on the side of the device. is this possible?

Sprint HTC Hero :: All Contacts Not Loading / Anyway To Force This?

Sep 2, 2010

I changed roms after backing up the one I was using and the new rom didn't load all my contacts. So I wiped it again and tried to reload the same new rom. Got even less contacts. So I wiped that and tried to load the nandroid b/up and for some reason, I got the old rom I was using but it was like it was a fresh install of that rom. So I have to set everything up again *sigh*, but it still didn't load all my contacts. Oddly enough, the ones missing are the ones I use most frequently. A quick check on google mail shows they are still there. Any advice?

HTC EVO 4G :: Facebook Contacts - Unsync Them In My All Contacts List Etc

Jun 4, 2010

Ok, so this is my first time with Android. When I first set the phone up with Facebook, it pulled EVERY friend I have and puts them in my phones contacts. After searching, I found that I can unsync them in my 'all' contacts list etc, but they are still showing up when I push 'PHONE' at the bottom of the home screen. They are behind the dialer. Is there anyway to set that screen to show recently dialed numbers or favorites or something?

Anyone else having problems with their contacts loading slowly? I am running fresh 2.3.3. If I understand it correctly, each time you select a contact, it actually 'downloads' the data from the 'google cloud'? Is there anyway to speed this up or just load the contacts on the SD card and it can more quickly pull it from the phone?

Android :: ListAdapter Repaint ?

Mar 22, 2010

i have the following problem. I fill a ListView with a custom ArrayAdapter with data from a BD. However, in background, i'm updating those datas from the info provided by an API, so the idea is when the update finish, the adapter shows the updated data instead its "old version".

The problem is that when i do that, i notice a lag while the adapter is updating itself. Is the any efficient solution to avoid this?

I've built an application that loads XML from a server, then creates a list of items and with that I create and adapter that I set with setListAdapter(my adapter);

The problem I'm having now is that creating the list and adapter takes time, so I was thinking on creating just like 20 entries and populate the list, then create the rest on runs background or maybe when the person gets to the bottom (like gmail application).

Android :: ListView And ListAdapter

May 25, 2010

I am trying to use ListView and ListAdapter. If I create a simple Android project and add a ListView as the content view, and set it's adapter to my adapter based on ListAdapter, everything seems to work. My ListAdapter's 'getCount' is called, and I return 3, my 'getViewTypeCount' is called and I return 1, my 'getItemType' is called and I return 0, and for each item, my 'getView' is called and I return a TextView. Everything works, and the list is displayed with 3 items.

Now if I try and do the same thing in a more complicated environment, it does not work. My 'getCount', 'getViewTypeCount' and 'getItemType' methods are called, but the 'getView' method is never called and the ListView appears empty.

Now I know that I must be doing something wrong in the more complicated case, but I cannot see what it is. The code is really too involved to post here, but I was hoping that someone could give me some ideas as to why my 'getView' is never called even though I return 3 from my 'getCount' method.
