Android :: ListView To Grow To Size Of Content

Mar 15, 2010

I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use?

Android :: Android - ListView Items Not Grow To Wrap Their Content

Nov 2, 2009

I have a rather complex ListView, with variable list item heights. Under certain conditions, I need to display an additional view in a list item, which is hidden by default (View.GONE). By enabling it (View.VISIBLE), the list item grows in height (or at least it's supposed to).

The problem:
Even though I declare the item's root layout to wrap_content, and each component in the item to fill_parent, the view I hide/show which is supposed to change the item's height is simply cut off at the bottom instead of its parent (the item layout) growing in height to fully display it.

Are there any gotchas related to ListViews and item layouts and item height which I may have missed?

Some more observations:

For testing purposes I have now reduced the list item layout to just contain the root LinearLayout and an ImageView. When I set the LinearLayout height to e.g. 200dip and the ImageView to fill_parent, I would have expected the ImageView to grow until it hits the 200dip limit set by its parent.

However, the image will instead be only ever as tall as its bitmap resource (as if I had set it to wrap_content) and the whole list item will be of the same height (i.e. as if I had set it to wrap_content, too).

If however I set the image height to e.g. 200dip, then the list item will grow in height, and so will the item layout.

In other words, the layout_height of the list item layout is completely ignored, and so is any height value on ImageView other than a hard-coded pixel value.

Android :: Dynamically Grow Listview

Nov 2, 2009

I am trying to make ListView which should display data from db. But the db is filled slowly so want the entries in the ListView to grow dynamically according to the elements in db. For example on a desktop music player when you import a folder to the music library the list with songs is filling in real time with the newly added songs. So how can i get this working on android.

Android :: How To Keep ListView Header From Scrolling With ListView Content?

Jun 24, 2009

There must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.

Android :: Changing The Content Of A ListView

Jun 10, 2010

I have added a menu to ListView Activity and wanted to allow the user to select the information that would be displayed in the ListView. So for example:

The ListView is populated in the onCreate method.
The user selects an option in the menu.
Upon the user making this selection the ListView would be populated with a different array.

Is onResume() executed after the menu is closed? I would test this but I am not currently home.

What is an efficient to refresh my listView? I don't want the listView to re-trigger a query since there is no data change.

Android :: Custom Separator In ListView Depening On Content Of Item

Oct 22, 2009

I've a ListView with items containing information about places with a rating and the distance to the current location.

The items are sorted into groups:

Group 1: within 500m
Group 2: 500m - 1km
Group 3: 1km - 1.5km

Withing these groups the items are sorted by their rating.Now I put out these items via my custom adapter (extension of BaseAdapter) into the ListView, which works perfectly.

However, what I'd like to do is to put a separator before the each first item of each group. This separator can be a TextView saying e.g. 500m - 1km followed by all the ListView items in that group. Any idea on how to realize this?

Android :: Adding Animation To A ListView In Order To Expand/collapse Content

Oct 3, 2010

I have a list view which uses a custom adapter in order to show my custom content. Its layout is the following.

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

I would like that the listview only showed the view with the ids itemimage and item description, keeping the itemtext hidden.

The idea is to have an onclicklistener on each item of the list, in order to expand that item so it shows the itemtext content. I know I should use Tweening animation in order to expand/collapse each item, but I can't figure out how to do that.

Android :: Change Size Of ListView Rows

Sep 22, 2010

I have 2 ways of displaying ListView data. I have a class for each type of row. I do not create the rows in an xml layout. (Each row is derived from View and does custom drawing). When I switch from 1 type of row to another how do I get the ListView to layout properly with the correct row heights, and refresh? Is View.forceLayout() on the right track?

Android : ImageAdapter And ListView (java.lang.OutOfMemoryError: Bitmap Size Exceeds VM Budget)

Jun 15, 2010

I'm using ListView to display images which I provide through an ImageAdapter class. it works great on my device (and on many other devices which I tested it on), but somehow when I'm using the emulator and I'm long-pressing the up/down button - I'm getting an outOfMemory error after 10-15 seconds.

I tried clearing cache, canceling cache, etc. - nothing helped.

I know this crash is pretty rare (i couldn't reproduced it on any "real" device), but I can see on DDMS that "GC freed" are getting bigger during that long press and I can't find a way to clear them.

Motorola Droid :: How Much Market Is Going To Grow With Quality Apps?

Jan 5, 2010

Just gotta say that they are in for a hell of a ride. The N1 looks to be an awesome device and they are going to get to have the kind of fun we've all been having with a spanking fast shiny new Android phone.More than that I'm really excited to see this tsunami of sweet Android devices to hit the market.It doesn't take much imagination to realize how much the Market is going to grow with quality apps.

That said, I'm still very happy with my Droid AND a little bit jealous of the N1 already, all at the same time. I may even buy it at some point in the coming months, but most of all, this is exciting news for the platform we all know rocks

Android :: Switching Content Providers For Same Content URI

Aug 12, 2009

This may seem like a stupid question but I need to be sure. I was wondering if it was possible to pro-grammatically change the Content Provider used when making a query given a Content URI. The reason being I need to know if it's possible to force the Calendar/Contacts applications to read from a different database via a different Content Provider temporarily while my application is running, so that I can reuse those applications to display my own data. Since the Content URI s are hard coded in each of these applications the only way it might be possible is if we could somehow temporarily change the Content Provider used for a given URI. I know this probably isn't possible, I just need to show it isn't. Could someone confirm this can't be done?

Android :: Android Grow Box Animation

Jul 2, 2010

Inside of a ListView row, I have a box (right now its an imageview, but i will probably be converting it to a linear or relative layout object at some point). when you click on the box, i have it start a scale animation that makes it appear to grow. however, once the animation is over, the box goes immediately back to its original state. I'd like to have the box stay at the transformed size (at least until they click it again).

Here's the xml:
