I am having a problem with ListViews. After adding a few items to the list and it becomes larger than the layout, my cancel button disappears. Scrolling and everything else on the ListView still work fine, but it replaces the views I have below it. Anyone else run into this issue? Am I missing something?
Here is an example layout:

I have a ListView that could have 4 different views for a row depending on the data for the row. I have the ListView working correctly overriding getViewTypeCount and getItemViewTYpe. I originally was trying to dynamiclly update the view type count as new views were inflated by forcing calls to getViewTypeCount because it was possible that maybe one or two views may be all that would be needed. The app never functioned correctly crashing after there was more than one view added. The problem was fixed by setting getViewTypeCount to always return 4. I noticed getViewTypeCount is automatically called on app start-up and never called again unless a force call is made. So I'm just curious if this can be changed dynamically or do you need to know the number of max views you can possibly have and override getViewTypeCount to return that max value.

View 3 Replies View RelatedI'm trying to make a ListView when every item in that list can be a different type of View. for example the list could be: 1. TextView 2. ImageView 3. MyCustomView
I understands that in order to make a list I need to use an Adapter. the problem is that the Adapter uses a single layout for all of the list items, which will not support the different views.
my goal is to make an abstract View list when I can dynamically add and removes items in that list (each item is a View or subclass of it).
I want to create a listview with rows that have an image and two textviews. This must be a very common activity but I can't find a class/or source code that does this.
View 9 Replies View RelatedIm using ListView to to show some custom data, once data is updated in the adapter i call notifyDatasetChanged(), so the view will get updated, all of this works well, my issue though is i would like to run an animation once only on items that got changed when the adapter was updated. currently i keep a copy of all the changed objects and i tried to animate the correct items through the getView() call.
However if i do it only once for every getView call then i see no animation most of the time on items that changed. if i continue to do so in successive getView calls i see animation on items that don not change as well and also the ones that changed get animated again and again.
Im guessing sometimes android calls the getView() for other reasons than showing the generated view immediately, and thats the reason it doesnt work if i do it once.
When i click home button and then come back to to my application it doesn't show the last values on the listview or any other view it just look same with when i started the application.I believe it is can be done with onResume and onPause but i couldn't find how.
View 3 Replies View RelatedI have TabActivity that uses 2 other ListActivities for the tabs. Both underlying ListViews are set to CHOICE_MODE_MULTIPLE. When I run the following sequence of events, I get a strange result: 1) Setup one activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 2) Reorient the screen (open the keyboard) 3) Setup the second activity (tab) and its ListView using a CursorAdapter, including checking some items on the list 4) Switch back to the first tab
At this point, I can see in Eclipse that although (of course) each ListView is a distinct object, the internal variable used to store the checked state of items, called mCheckStates, is the SAME OBJECT REFERENCE in each of the ListViews.
Clearly this is an issue, since the two views should not share the checked state of items between them.
If I skip step #2, this does not occur
Here is a bit more detail:
After Step 1: ListView1 is object reference @1, ListView1.mCheckStates is object reference @2
After Step 2: ListView1 is object reference @3, ListView1.mCheckStates is object reference @4 (the reorientation recreates the views)
After Step 3: ListView2 is object reference @5, ListView1.mCheckStates is object reference @2 <-- note the reuse of this reference from step #1, not sure how/why
After Step 4: ListView1 is object reference @3 (unchanged), ListView1.mCheckStates is object reference @2 (changed) <-- same as ListView2.mCheckStates
I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?
I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table
CODE:.................
I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.
How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.
View 2 Replies View RelatedIs there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

View 1 Replies View RelatedThere 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.

Tried to debug this in Eclipse but didn't find the cause.
I have installed the Android SDK and plugin for Eclipse and written my first test app. I am trying to view the device in the DDMS section of Eclipse, but my Android Virtual Machine is usually not listed in the Devices section when it is running. Occasionally it will appear for a minute only to disappear again. I found an article recommending that I run adb kill-server to get it to restart and appear. This works about 50% of the time, but the device just disappears again in 10-60 seconds. My main desire with this is to push some files to the sd card on my Android Virtual Machine, but the device doesn't stay visible long enough to push any data to it.
View 4 Replies View RelatedI've just move from the Iphone 4 to the S4 and am trying to set it up. I'm failing miserably with email.
I use Virgin.net email but have it downloaded to Outlook and it is deleted from the server when I do this.
I want to access the same emails on my phone - well, those emails that have not yet been downloaded from the server. So for example, if I'm not at home and laptop is switched off (not accessing Outlook) then I can get the emails to my phone until I get home and download them to laptop. When I download them to my phone I want to leave a copy on the server for Outlook to get.
So............... I've manually set up email using pop3 settings on S4.
An email will download to my inbox on the phone...... but then when I next go in to check emails on phone those that have been downloaded just disappear?
Delete email from server is set as never in the settings. And outlook on my laptop is turned off so emails are not being downloaded there.
Why are my emails auto deleting and where re they going. How do I stop this?
I've heard this happening with Gmail to other people, but I didn't believe it, now it's happening to me. I had a very very very vitally important email sent to me yesterday, and after viewing it, it just vanished. Gone for good. I can't find it. I've checked every folder, I've checked All Mail, I've checked trash, I've checked spam, drafts, everywhere. This is the 3rd or 4th time I've had an email vanish in the past 3 months. Completely gone, as if it never existed, without me deleting it.Has anyone else experienced this with Gmail? I know a few people who don't use Gmail for this very reason, but I thought they were crazy, now it's happening to me. HELP! I need that email back

View 3 Replies View Relatedevery time I have looked at the market comments for my app over the last few days some more comments have disappeared. This is whether I look on the phone or on the developer console.Unfortunately the comments that Google has chosen to 'lose' are my most favourable comments leaving several "This app suxss" type comments by the usual Neanderthals who like to be abusive. I have checked with a helpful user who left a positive comment and they have not removed them themselves or de-installed so what is going on? It is seriously hurting my downloads/sales and the impression that potential users of my app see when they look on the market. I have emailed Google but no reply yet.
View 6 Replies View RelatedOver the past few days I have been trying to implement custom widget functionality. In this case I have instantiated a RemoteView containing some TextViews and an ImageView in one application's BroadcastReceiver. The BroadcastReceiver receives the intent signaling it to send the RemoteView to the calling application. When the calling application receives this RemoteView it uses apply to inflate the view properly and display it on the screen.
The problem occurs when the activity changes, the inflated RemoteView occasionally has information disappear. One time the image even changed into another image from a drawable located in the BroadcastReceiver's application. Has anyone else experienced a similar problem and/or have a solution?
I have looked at posts concerning ImageViews in widget use and orientation changes. Is this problem related? I am not entirely sure. I am currently running Android 1.5 SDK and am not able to upgrade for this side project of mine.
