I want to implement RadioButton and EditText inside a row of a ListView. I am using an ArrayAdapter to populate the List. But the problem is that when i am selecting a RadioButton and scroll down the list and scroll up again the Radiobutton which had been selected is unselected. Same with the content of the EditText. The text getting removed when I scroll up.

I've spent about 6 hours on this so far, and been hitting nothing but roadblocks. The general premise is that there is some row in a ListView (whether it's generated by the adapter, or added as a header view) that contains an EditText widget and a Button. All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row -- even if I have to explicitly identify the row -- that has a focusable child, I want that child to take focus instead of indicating the position with the selector.I've tried many possibilities, and have so far had no luck.
Assuming there are other items in the adapter, using the arrow keys will move the selection up/down in the list, as expected; but when getting to the header row, it is also displayed with the selector, and no way to focus into the EditText using the jogball. Note: tapping on the EditText will focus it at that point, however that relies on a touchscreen, which should not be a requirement.ListView apparently has two modes in this regard:
1. setItemsCanFocus(true): selector is never displayed, but the EditText can get focus when using the arrows. Focus search algorithm is hard to predict, and no visual feedback (on any rows: having focusable children or not) on which item is selected, both of which can give the user an unexpected experience.
2. setItemsCanFocus(false): selector is always drawn in non-touch-mode, and EditText can never get focus -- even if you tap on it.
To make matters worse, calling editTextView.requestFocus() returns true, but in fact does not give the EditText focus.What I'm envisioning is basically a hybrid of 1 & 2, where rather than the list setting if all items are focusable or not, I want to set focusability for a single item in the list, so that the selector seamlessly transitions from selecting the entire row for non-focusable items, and traversing the focus tree for items that contain focusable children.
I have a RadioGroup inside of a RelativeLayout. I've got a few RadioButtons for different options, like "Bob", "Joe", and "Fred". However, I need to add an "Other..." option with an EditText right next to a RadioButton in case a user wants to enter "Steve". Is there a way to do this?
View 1 Replies View RelatedI want to create a ListView with a RadioButton in every row. I'm using a CursorAdapter and I'm binding it in the right way, but I cannot manage correctly the RadioButton. I want that at any moment only one RadioButton to be checked (so when I check one, I would like the one that was checked before to uncheck). Furthermore, when I put the RadioButton on the row, I cannot manage anymore the setOnItemClickListener.
View 1 Replies View RelatedSo I've been extremely frustrated by this for a long time now.I've posted before, but can't seem to find a good solution. My goal is to have something pretty much exactly like the installed application details page in the Android Market.I need a list of items displayed along with other content above the list, and would like the content above to scroll up along with the list (exactly like the application details does for the "My Review" and other descriptive info).Due to responses to my previous posts, I came to believe that it really wasn't possible to do this with a ListView.So rather than using a ListView, I refactored my code to use a simple LinearLayout and add individual View items to the list, thinking I could just set each View as clickable and add an OnClickListener to each View in the LinearLayout.That's not working at all though, and now I'm getting even more frustrated.If someone can help me get the OnClickListener working, then I think it'll work, but I do need a separator for the LinearLayout.How do I add a separator like the one used for ListView to my LinearLayout?
View 12 Replies View RelatedI have a ListView, which is in singleChoice mode. All I want is to display a RadioButton to the side, that when clicked highlights to say it is selected, and when a different one is clicked that one goes back to unselected and the new one becomes selected. Why is this so hard? This should not be this complicated. I've spent DAYS looking for an appropriate answer to this and I have found nothing, so I'm asking hopefully in a clear and concise manner.
My layout for the listview (R.layout.view_orders):
CODE:.............
My custom row (R.layout.orders_row):
CODE:.................
My onCreate() method:
CODE:.................
Now everything underlying works as expected, you click on a radiobutton and through it's tag I can appropriately select that item from the list and manipulate it how I want. However, when the first radio button is clicked, the last one will be selected. Click that same radio button again, and it is now selected as well. Click it once more and nothing happens, both the last and the first are selected. Now I click any other one on the list, it gets selected like expected. Click anyone of the selected radio buttons and nothing happens, the radio button remains selected.
I have tried using the following in onCreate():
CODE:.................
And that just shows no radio buttons at all. AWESOME.
Now maybe (read: most likely), I'm just dense and can't figure this out, but I've seen this question asked a lot with no real answer. Lots of references to other tutorials or to the Commonsware guy's book. However, the comments are old now and his repository has changed so much, that those are no longer correct answers.
So, does anyone have any idea how to get the expected functionality out of this? Or failing that, just pass me along the GMail app's source code.

Do I need to specify something special for the listview or the tabhost, or do I need to call some update/invalidate function on the tabhost after updating the list?

I've got a ListView where each item in the list is contains several controls. One of the items is a checkbox, and I can check/uncheck it without problems. The other items are some TextViews and a WebView. I've got autoLink turned on and linksClickable turned on, but I can't get links to fire up the browser when I click on them. This applies to both TextView and WebView. I've tried changing the parent to a GridView instead of a ListView, playing with setFocusable(), and all that, but to no avail.
Is it even possible to have interaction on the TextView-based elements of a row in a ListView? It seems like that *should* be possible, but I've been banging my head against this problem for a few weeks with no progress. What's the secret?
I'm building a chat room application where new events are being polled for every X seconds. Every time that happens, this code updates the RoomAdapter (a custom subclass of ArrayAdapter) with the new data and scrolls it to the bottom:
RoomAdapter adapter = (RoomAdapter) getListAdapter();
for (int i=0; i<newEvents.size(); i++)
adapter.add(newEvents.get(i));
getListView().setSelection(events.size()-1);
This is fine, except that if the user is scrolling up to glance at the room's history, it's going to jump her down to the bottom when the poll happens. What I'd like to do is have it so that if the user is already at the bottom of the list, it stays there after a poll for new events. If the user's intentionally scrolled upwards, I'd like the user not to be disturbed.
How do I detect when I'm already scrolled to the bottom of a ListView?
Note: I can't do getListView().getSelectedItemPosition(), because as the docs note, calling setSelection when in touch mode does not actually select the item, just scrolls to it.
I have a ListView, which contains an EditText in each of it's row. I also have an Array.The length of the Array==the Nr of the rows in the ListView. I want to store the user input (the text in the EditText) to the Arrray. E.g, if i type some text in the EditText in the first row of the ListView, i want the text to be stored in Array[0]. But how can i detect to which row the EditText belongs to? I can detect the possition of the row if the row contains a RadioGroup, but not a EditText. What if i first type some text in the EditText and sometime later i want to update mein Input? How can i update it?

View 4 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.
I implemented a gallery, and inside it I have many listviews from left to right. For some reason Gallery works great with all views but not with listview. With listview, when scrolling on the gallery, sometimes I get little jumps.
Some notes: The gallery uses an adapter to find out what to show, and then the listview is created based on the adapter
I have quite a complicated ListView. Each item looks something like this...
In my activity, when an item is created (getView() is called) I add dynamic TextViews to the LinearLayout inside the HorizontalScrollView (besides filling the other, simpler stuff out). Amazingly, performance is pretty good.
My problem is that when I added the HorizontalScrollView, my list items became unclickable. They don't get the orange background when clicked and they don't fire the OnItemClickedListener I have set up (to do a simple Log.d call).
How can I make my list items clickable again?
Edit: setting android:descendantFocusability="blocksDescendants" on the topmost LinearLayout seems to work. I'd like to know if there are other ways, though: what if I want focusable items in my list items?

I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.
Can I modify android.R.layout.simple_list_item_1? For eg., I want to change the text color of the textview inside the listview dynamically. For this, I need to get to the textview and change its color.. How can I do that?
