Jul 30, 2009

I'd like to use CursorAdapter but Cursor its based on cannot be returned by simple sql query, since in db i have two fields and based on some criteria they build the String that would be displayed in the ListView.

what is the best solution: forget CursorAdapter and use ArrayAdapter or MatrixAdapter iterating over my db Cursor and adding rows, or maybe use CursorWrapper or some ither solution?

Android :: Listview - Conditionally Replace A Value With A String?

May 24, 2010

My ANDROID app presents a listview, from a database cursor and XML, that needs to replace the values in a column with various words based on the integer value contained in the cursor. For example, if the value is -1, replace it with the word "Invalid", but if the value is >= 0 then just display the value.

I was under the impression this could magically be done via XML.

Android :: Display This Listview On Scrolling?

Mar 18, 2010

I'm completely stumped on this one. I have three different lists that need to be displayed on the screen.
I've tried using a ScrollView with a LinearLayout child, and putting my ListViews in the LinearView, but all of the ListViews lock to a fixed height with scroll bars. Using other kinds of Layouts means no scrolling.

Android :: Display Twitter Timeline In ListView

I'm pretty new to Android development and would appreciate some help. All I want is to display a ListView showing a Twitter timeline. I do this in an iPhone app using MGTwitter but I've been trying and am not sure how to get the same effect on Android. I can use a list view, but I'm not sure how to get the updates.

In a nutshell all it has to do is display the updates at www.twitter.com/user (User will be hardcoded).

Android :: Display All Contacts With Numbers In One ListView

Apr 8, 2010

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.

Android :: Dynamic Display Of ListView Elements Partially Working

Jul 26, 2010

I am making a time sheet program where a user inputs his in- and out-punches. I have a ListView that I am populating from an array of calendar objects. I would like each row to show the day and date then on a new line the time, but I only want to display the day and date if it is different from the previous element.Currently, I am setting visibility in the Base Adapter based on comparisons using position vs position-1 (which are used as indices to the array). This only works if the whole list fits on the screen. If it extends beyond the screen and the user scrolls around the results are unpredictable.To further confuse things, I am setting the color of the times, based on the position, to alternate between green and red (in/out) and it works as expected, scrolling or not.How does Android handle the ListView position when scrolling or what could I do differently to show/hide the day and date? Code...

Android :: Listview Display All Available Items Without Scroll With Static Header

Nov 22, 2009

I'm having a little difficulties while trying to get a certain layout to work: I want to have list. List does not have to be scrollable, but should be shown completely. But the page itself should be able to scroll (with the lists in it), if the total content ist higher than the screen.

CODE:.................

It only uses a small part of the screen (about 2 lines per list), instead of filling the available height, and the lists themselves can be scrolled. How can I change the layout to always show the whole lists but have the screen be scrollalbe?

Android :: How To Display A Loading - Text While Retrieving Items For A ListView

Jul 26, 2010

There are some others applications doing this, like Twitter, Facebook, or even native applications such as Android Market. When you want to display a list of items retrieved from the internet, this looks like a standard way for displaying the user some notification about action in progress. This is a white background screen with an animated spinning wheel and a "Loading..." text. Does somebody know how to do this?. I've been able to do something similar with this code, but i don't like it too much yet.

Android :: How To Add A Button In Top Before The Listview

Sep 1, 2010

I have written a ListView with a text and image clubbed together in a row. I wanted to add a button on top of listview, then the entire content of listview should be seen. Button is named as "More", when someone clicks it i will be updating the listcontent. That is the main theme.

My java file.

CODE:.....

* Demonstrates how to write an efficient list adapter. The adapter used in this example binds
* to an ImageView and to a TextView for each row in the list.
*
* To work efficiently the adapter implemented here uses two techniques:
* - It reuses the convertView passed to getView() to avoid inflating View when it is not necessary
* - It uses the ViewHolder pattern to avoid calling findViewById() when it is not necessary
*
* The ViewHolder pattern consists in storing a data structure in the tag of the view returned by
* getView(). This data structures contains references to the views we want to bind data to, thus
* avoiding calls to findViewById() every time getView() is invoked.


CODE:.....

My xml file. /res/layout

Android :: Button In ListView

Mar 15, 2010

I have a problem that some other people on this list (and other android sites) also have/had, but was unable to find a solution. I have a ListView with a custom view for the row which looks like this: <RelativeLayout><ToggleButton/><TextView/></RelativeLayout>

Its basically a list of songs that i show. What i want to achieve:

If the user clicks on the ToggleButton the song should be played. If the user clicks somewhere else on the row, the details intent of the song should be launched.

So I want to have two events on every row, event1: the button click, event2: click somewhere except on the button.

Right now i have a custom adapter where i call .setOnClickListener() on the button. Now the button works (event1 works), the song is played, but the rest of the row is not clickable (event2 does not work). If i remove the call to setOnClickListener() the row is clickable (event1 works) and the details are displayed as suppossed, but the button is not working. (event1 does not work)

There are apps out there, that have buttons in lists so this must be possible. Could someone please tell me how to have more than one click event on a lists row?

Android :: Cannot Display Image Correctly Using Custom Item Layout In ListView

Apr 22, 2010

I am using a ListView to display my custom item layout, which may contain some TextViews and an ImageView.

This is the item layout I made (post_item.xml):

CODE:........................

I don't put the ImageView initially in the xml layout, but I will insert it when I need to the FrameLayout programmatically (I also put another views in it when needed). So, there will be some items which has ImageView in it and which don't.

I get the image to fill the ImageView from the Internet (through URL), decode it as Bitmap, and keep it as a Bitmap variable in a class represents the custom item layout (class PostItem).

When the activity shows for the first time it looks fine, but as I scrolled through the items then a problem showed up, the items which shouldn't show any image show the image from the other item which should, although they don't have any ImageView (because I didn't insert it).

I am using SDK 1.6 and the emulator. Haven't tried it in real device because I don't have it.

Here is my code for the Adapter:

CODE:..............

And this is the code to prepare the items:

CODE:.........................

Is this the bug in the emulator or there is some mistake in my code (probably memory problem for the Bitmap)?
