Android :: ListActivity With ArrayList Of Objects As Layout Resource

Nov 24, 2010

I need to display a list of categories from a ListActivity. My data source is a ArrayList of type Category which is implementing the android Parcelable interface. stucture is given at the bottom. it has an id and a title

I need title to be displayed as list text and on clicking the list item, i need to get the id for further processing

It is possible to create a new array of 'title's by iterating the category ArrayList and use


But bu using this method i will get only the title of the category upon click and not the id.

Is it possible to directly use the ArrayList of objects as data source?

Android :: ListActivity In Tab Crashes

Oct 26, 2009

I'm trying to create an application that has 3 tabs. Under the middle tab should be a ListView. It starts up fine (on the left tab) but when I click the middle tab it crashes.

The other two tabs are static data specified in the main.xml file. But the middle tab, I try to create dynamically. Here's the code from the main onCreate function:


Instead I appear to get an exception:


ContactListActivity is defined this way:

public class ContactListActivity extends ListActivity { ...

I get the feeling that I'm supposed to create the Intent with something like Intent.ACTION_VIEW but this is where I get lost. If this is the problem, I could try stuff until it works, but I'd prefer to understand why.

Or is ContactListActivity supposed to override something ?

Android :: Rotation With ListActivity

Feb 8, 2010

I have a problem with rotation, during my ListActivity is loading data from the network. To do it I use a background thread which recovers data and put them inside an ArrayList. While this thread works, there is Progress dialog activated in foreground. For the rotation I use the method with onRetainNonConfigurationInstance() to save my ArrayList's state. After android calls this method, I call dismiss() on the progress dialog on onStop(). Then the activity is created as new with onCreate(), but it use the getLastNonConfigurationInstance() to recover the ArrayList's state. Now, my problem. If I rotate from portrait to lanscape when the download is terminated and I see the data in portrait yet, everything is ok. If I rotate during progress dialog is showing I have two cases: 1- onRetainNonConfigurationInstance() saves the arraylist fully recovered, the thread terminates and everything is ok. 2- onRetainNonConfigurationInstance() saves the arraylist empty, i think the download isn't finished yet. The onCreate is called and my list is empty, the thread terminates, but i don't see anything in my list. If I am in this case and I still rotate from landscape to portrait now I can see my list full with all the data. Why? Where am I wrong?

Android :: ListView And ListActivity

Jun 30, 2009

I create a ListView in my activity and set its ChoiceMode to CHOICE_MODE_SINGLE, I also set its layout to simple_list_item_single_choice. But when i click on it onItemSelected() is never called and getCheckedItemPosition() returns -1. Why? the sample of ApiDemos uses ListActivity works well which just set the same as I done in my app. Any ideas?

Android :: Using ListView Without ListActivity

Jan 13, 2010

I want to create a custom list view in my application. I want it to lay over the top of the application screen, with portions of the screen not filled by the listview showing the underlying application. I've been reading about ListActivity, how it can be started to handle item selected callbacks. I've also read about people simply inserting onClick handlers into the listview as it is drawn. I'm trying to decide the best way to proceed. Is it "dirty" to attach onClick handlers to the rows of a listview? It doesn't seem like the best approach, for instance, it only handles Touch Mode, not the DPAD clicks. This approach doesn't seem like what the architects had in mind. On the other hand, I don't see a good way that I can start a list activity and still have access to all the application variables I need. Do I pass the application in the context and refer back to it from even handlers after casting the context back to it's original class?

Android :: ImageView In ListActivity

Jan 11, 2010

I have an ListActivity that I wan't to add a logo to at the top above the list but I'm unsuccessful. This is what my layout looks like at the moment.

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/logo" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false"> </ListView> <TextView android:id="@+id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/list_empty" /> </LinearLayout>

Then I add an drawable to the ImageView logo in onCreate. I've managed to show either the ListView or the ImageView but never both of them in the same LinearLayout. Is it possible to add other views together with a ListView?

Android :: ListActivity Out Of Memory

Sep 8, 2009

I am using a ListActivity. Each list entry contains an ImageView and a TextView. I have a huge list and has been getting Out of Memory errors once I scroll through a fair amount of them. I figured I need to reduce the size of the images but I am wondering what happens to the objects once the list entry is hidden from view (as i scroll down the list). I have read somewhere that the list entry objects are automatically re-use. But what happens to the drawable images which were loaded into the ImageView? IF the ImageView object is reused, what happens to the binary image? Are they freed automatically? How do I prevent the OutOfMemory exception? I want to do something similar like the Android Market. As one scroll downwards the images are loaded and new entries are loaded. The Markey can have a long list which one can scroll down and all the way back up again without any problem. The only difference being mine throws OutOfMemory Exception. Advice anyone?

Mar 7, 2010

I have the following setup, and the empty view text doesn't show up...


The layout file is:


String is defined as: <string name="contact_empty_help">"You don't have any contacts to display.

Android :: Unable To Open Both Main.xml Files / From Layout & Layout-land At Same Time?

Aug 14, 2010

While developing for Android, I am unable to open more than one main.xml file in an Eclipse editor at a time.Each time I open one, it simply replaces the editor (tab) of the first main.xml with the new one, instead of opening a new tab - even if the contents of the existing tab were unsaved.Even stranger, I can open multiple main.xml files from different projects with no problems.This only happens when they're within the same project.

Android :: ListActivity OnListItemClick Not Being Invoked

Sep 18, 2009

Scoured the docs and forums, couldn't find an answer or reason why this is happening: I have a class that extends ListActivity and a View coming from XML for each row that looks like this:

<LinearLayout ...> <TextView ... /> <TextView ... />
<CheckBox ... /> </LinearLayout>

When I click on one of the items in the list, the onListItemClick() i have in my activity is not invoked. Turns out, if I comment out the CheckBox node in my layout xml, it works. I feel like there is a simple explanation that I don't know about.. maybe because CheckBox is an actual interactive widget it's overriding some click action or something?

Android :: Refreshing A ListActivity Within TabView

Nov 20, 2009

I'm running into some issues here with my app. I have 4 tabs run through a tabActivity. One tab sends an intent and run my ListActivity that populates the screen from a simpleCursorAdapter. My problem is that when I change back to this tab, after the first time its run, the list never refreshes regardless of the changes made to the database via other tabs. Is there something I can call from onTabChanged to refresh my ListActivity?

Android :: ListActivity Mandatory For ListView

Dec 3, 2009

I am starting with ListActivity.

I saw apidemos and saw that it is based on ListActivity. My doubt is, in my first screen I need a few labels and texts under that a list. How to approach this ? I cant do a setContentlayut( if my activity extends ListActivity, no ?

more over I found the tutorial posted in the forums for ListActivity a bit outdated. Where is 1.5 / 1.6 based tutorials ? because I am new, it is taking too much time to correct 1.1 codes.

lastly, if i have a todo type appfor adding deleting and deleting, should i use 3 different layouts or activities ?

Android :: How To Switch From Activity To ListActivity?

Jul 24, 2010

This post probably shows my ignorance of Android coding, but here goes. I have a sample app I am developing which starts by extending Activity. I have a main.XML layout which works great. On a button click from the main layout I'd like to load a ListView. I think I understand how to use ListView and seed data into it. I have created a new layout which contains this ListView. I am confused, however, how I switch from a regular Activity to a ListActivity so I get the convenience methods like setListAdapter()? Should I be starting with a ListView, and then drawing the other view on top once the app starts by inflating the layout and using it? If not, how do I create a ListActivity object inside my app, and where should I create that? If you have a sample application or tutorial that shows how to do this, I would appreciate it.
