I'm trying to copy the content of a certain row in a listview, so I can change it and later reload that row content.I've tried defining a new LinearLayout and then getChildAt(), but it's working. Is there some sort of clone or copy that I'm missing?

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.

View 5 Replies View RelatedI 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.
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?

View 2 Replies View RelatedI have a ListView in my android activity. And I populate the ListView by sub-class the BaseAdaptor (which returns a View in getView() method).
What if in my click listener of a button in a list item view, I change the text of the TextView in the List item view or change the dimension of the list item view by adding/removing children of the list item view
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.
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?
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.
I have a ListView displaying images on every element of the ListView, It works fine... but when I start to scrolling I have realized my image is downloaded again if it is displayed in the screen of my phone device!
How could I stop reloading the images or all the content of the in ListView again?
Or how could I avoid reading the getView() function again If I have already downloaded all its content?
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.
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?
View 2 Replies View RelatedI am having a hard time understanding content providers. In the notepad example and others, the content provider never even declares its CONTENT_URI anywhere inside itself, yet the docs say to publicly declare this. It's declared in a different class. So when an activity queries a content provider with a CONTENT_URI, how does Android know which one I want. I see no link between a content provider and its CONTENT_URI declared in another class.
I also don't how to think about intents and content providers. I know that you don't call an intent on a content provider. But an activity queries a content provider without an intent, and an activity has a mimetype attribute in the manifest that would seem to tie it to a content provider.
how can i create a custom content provider like contact content provider? i know how to create custom content providers but i want to integarte to device such a way that it canbe accessed by all application installed in that device.

View 2 Replies View RelatedMy goal is to be able to copy everything in contacts (Phone contacts, Google accounts, Yahoo accounts, all contact photos, e-mails, home addresses, notes etc. everything...) to my SD card or SIM card. My first question is why does the SGS have a 'copy contacts to/from SIM' feature? Is this for when you are taking your SIM from the SGS and putting it into another phone (or vice versa)?You lose so much of your info (everything but name/number/e-mail) when you copy your contacts to your SIM. Wouldn't it be better to copy everything to your SD card and put your SD into your other phone, then copy the data to your other phone's contact list?
