View 24 Replies View RelatedI am using a ListView in which only one item can be checked at a time.
This is my custom list_row.xml :
CODE:..........
I populate the list in onCreate() using a normal array adapter :

When the list is displayed, I want to have, say the 5th item, in the list as Checked. How can I go about doing this? I know CheckedTextView has a function called setChecked(), but how can I get my 5th item from the list to apply this function on it?
I'm facing problem in scrolling. I've 20-25 items in my List, if i checked first check box, scroll down, then come up, my checked status lost (becomes unchecked), in cursor adaptor. If i use base adaptor problem is resolved but major issue with base adaptor is performance, if my list goes beyond the 100 items.

I'd like to create a list with an image on the right side of each entry - and preferably have a separate callback if the image is clicked.
much like the contact call-listview - can click on either the name (edit) or the phone icon on the right (call).
just wondering what kind of list and/or adapter i have to use.

View 2 Replies View RelatedI have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

Now my requirement is to create listview inside it. i know we can create textboxes,buttons,dropdown list inside it. but in order to create list view we should inherit our class from listActivity class. is it possible or not if yes then how to achieve this using any interface or what?
Just have a look in the system app contacts --->add new contact, this activity have a listview with different structured views for each row. I could do this by override the "getView" method, but a problem I'm facing is edittext will lose focus when I click on it. What happened when the view enter touch mode?
View 4 Replies View RelatedI want to create a customized ListView (or similar) which will behave like a closed (circular) one:
scrolling down - after the last item was reached the first begins (.., n-1, n, 1, 2, ..)
scrolling upward - after the first item was reached the last begins (.., 2, 1, n, n-1, ..)
It sounds simple conceptually but, apparently, there is no straightforward approach to do this.
I have already received an answer (from Streets Of Boston on Android-Developers google groups), but it sounds somehow ugly :) -
I did this by creating my own list-adapter (subclassed from BaseAdapter).
I coded my own list-adapter in such a way that its getCount() method returns a HUGE number.
And if item 'x' is selected, then this item corresponds to adapter position='adapter.getCount()/2+x'
And for my adapter's method getItem(int position), i look in my array that backs up the adapter and fetch the item on index:(position-getCount()/2) % myDataItems.length
You need to do some more 'special'stuff to make it all work correctly, but you get the idea.
In principle, it is still possible to reach the end or the beginning of the list, but if you set getCount() to around a million or so, this is hard to do :-)
I want to create a better NumberPicker then the one used in DatePicker, I looked at the HTC Sense Alarm clock Roller (Looks like the iPhone Spinner/Roller). I want to create something like that.
I've created a listView that looks right, but I need a way to get the current id of the middle row. ListView.getFirstVisiblePosition() kind of do what I want but it will give me +-1 errors. Another problem is that the scrolling should lock into a certain row when "dying" out. These are of couse related and I hope I can solve this by using a custom ListView, but it's hid in the API
Any thoughts on how to solve this?
What I want to do in one of my tabs in my application is have a ListView of contacts. Though, in that example, the ListView is made from an array of Strings. Is there a way that I can create one of those using the values from an ArrayList?

View 4 Replies View RelatedThis maybe against the way the Android team wants this to work, but if not I can't seem to come up with a way to do this. Basically I have a list view that I want to create a ContextMenu when onListItemClick received. So when the user clicks on a list item I want them to choose the action from a ContextMenu. Anyone have an example of how to do this, I can get it to work with no problems with a long press, but my users are missing the menu and just thinking the ListView does nothing.

View 1 Replies View RelatedI have a ListView that uses Linkify to create a link to another activity in my app. the url looks something like content://com.myapp/activitiy/view?param=blah
This works fine every time.
However, in another view, I'm trying to call some code like this:

But for some reason this doesn't seem to work. It doesn't trigger my activity (and in fact it blows up if i dont include the setAction() call. How am I supposed to create the Intent such that it acts the same way that Linkify does...?
Now i realize i can setup the extras and then handle it in the activity, but that just seems like duplicated effort.
