Android :: Inflating 2 Different Layouts At A ListAdapter On Android

Sep 21, 2010

I have a listview and i inflate the first position with a layout and every other position i do
another inflation with another layout.
I can do that by checking every time in getView, but as you can imagine this is not very efficient.

Can you share me your thoughts to get that result by having this pattern? (This don't get me the correct result(cause after 4-5 positions, depending of the number of positions inflated the first time, i get the layout.inside_list_2 on other positions too.)

Android :: Rules For Inflating Layouts

Sep 28, 2009

i'm running into some issues inflating layouts and i wonder whether i have something basic wrong.i have a ListView with a custom adapter etc, and of course the item View is custom too. i've been creating the item View in code, and everything works fine, including recycling them and all that. great.but i want to move the View into a resource, where all good Android views live, and weirdness is the ListView's getView(), i get my inflater and inflate the view by ID. the view itself has its own XML file. i can inflate the top view, but i can't find anything by ID, and when asked for its children, nothing comes back.are there funky rules for inflating views this way? is there a convention for how this should be done inside a ListView?

Android :: Multiple Activites That Share 75% Of Layout - Layouts Within Layouts?

Sep 6, 2010

I'm creating a game where there's a screen that, for the most part, is shared by four different activites - but a key portion of the screen will be completely different, depending upon which activity is active. Basically, on the left will be an image of the player and along the bottom there will be a row of buttons (let's say for Armour, Weapons, Magic, Skills). This leaves the top-right portion, which will need to dynamically change to represent the button pressed. (So, one moment the top-right portion is the armour selection activity, and the next it's the weapon selection activity, and so on.)

Is this possible? Can I have a layout within a layout and dynamically point the nested layout at a (nested) layout.xml of my choosing? Or, am I looking at just duplicating most of the layout four times (for the four different activities?) Or, am I going to be looking at linking the four activities to a (the top-right) view component, and then having to dynamically construct all of *that* view's child views based on the currently active activity? Well, that's about as much sense as I can make this question make.

Android :: Error Inflating Class

Sep 17, 2010

I'm new to Android development and I've been having an issue that I haven't been able to fix. I'm mostly using code from examples provided in the SDK so I'm not sure what's happening here. I'm simply trying to create a custom view GhostSurfaceCameraView that extends SurfaceView. Here's my class definition file


And this is in my ghostviewscreen.xml:


Now in the activity I made:


When setContentView gets called, an exception is thrown:

Android :: Inflating A View Into Button?

Jun 30, 2010

Let's say for instance a button is needed with a picture and a text. It would seem natural to create an xml view and then inflate it into the Button. Is this possible?

At the moment I don't need the button to look clickable or change it's color at click, but it could also be interesting to consider how this will be affected by making the inflate.

Btw, I found this one tutorial describing a solution to the same problem, but they were writing a class extending View to obtain the goal. That seems a bit overklill to me.

Android : Error Inflating Class - Bitmap Size Exceeds VM Budget

Nov 3, 2010

Posted my problem here too HERE: A beginner..Im doing a school map app.

First of all I have background with 4 buttons ( level3, level4, level5, level6) I try and click all the buttons, normally after clicking 3 of it, the next one will crash.(each level button goes into a level map, whereby clicking the room image buttons, I will enter into the gallery-imageswitcher)

I have at least 5 imageswitchers in each level maps,so that about over 20 imageswitcher galleries overall.

I did all my stuffs using DRAWABLES instead of BITMAPS.. I have tons and tons of images (because its a school map, show all the photos in my school, and all those backgrounds and imagebuttons)

I did some research, and those who have problems are those using bitmap. Some of the ways that can be solved is system.gc();, and bitmap.recycle...(not so sure how to use it though)

In my main background - Code...

PS: I have tons of images in the app; I have at least 5 imageswitcher gallerys in each level, so that kinda adds up to over 20 imageswitchers in my app.

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?

Android :: Populating A Listadapter?

Feb 18, 2009

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.

I'm experimenting with the Android platform, and I'm beginning to love it, but right now I'm stuck, at this cursor/list adapter problem-thing.

The thing is, that I request a function, returning a data object, with several properties I'd like to map to different TextView's.

So what I would like to do is: Map a property of an array of objects to several fields in the file.

Android :: Bind Data To ListView Without Preparing ArrayLists For ListAdapter?

Sep 14, 2010

I get my Models in a nice object-oriented form. In order to bind them to my List, I have to use the listAdapter. Can I only fill this listAdapter with stupid ArrayLists? Because that means, I have to iterate over my ModelCollection and pull all the data out of my Models again. So, I detach my data from the models and I cant easily refresh the data in my listView, if something chances in the modelCollection (like becoming bigger through new Items / pagination). Does a more intelligent way exist, than I use right now? Can I bind my ModelCollection more driectly to the listView?

ModelCollection modelCollection = ModelCategory.findAll();

* Prepare Data for Adapter
ArrayList<String> itemTitles = new ArrayList<String>();

// Iterate over my ModelCollection and pull all the Data from each Model
for (int i = 0; i < modelCollection.items.size(); i++) {....................
