I have a list that gets refreshed every 2 seconds via the Handler postDelayed() method.Every 2 seconds an AsyncTask is run that makes an HTTP GET request, turns the JSON into a list of objects, then sets the ListAdapter.My problem is that every time the task completes (so, roughly every two seconds) my list jumps back to the top, even if I have scrolled down to the middle or bottom of the list. This would be very annoying to the end user, so I need the list to update in the background, as it's doing, but the current view of the list to not jump back to the top at the completion of the AsyncTask.I can include any more code needed. I'm somewhat new to android development, so I'm not sure what is helpful to others.

This seems to be the perfect case to use a ContentProvider, but I don't see anything indicating that one can be used with either ItemizedOverlay or anything else related to the Google Maps API.
View 14 Replies View RelatedI have two cursor, one of them from contact content provider, other one from database. id fields are sycnhorinzed.i want to show them in same column with two row in list. i m think that i have to use simpleCursorAdapter, because arrayadapter and other adapters can not show two cursor in a list.
CODE:..........
So my list is not refresing/updating altough all cursors all results are updating.
i want to know how to refresh the ListActivity when i change/add data to the list wich is dispayed.i first thougt the ListAdapter would know when the list is changed but when i add elements to the list there is no update, only when i close the activity and reopen it i see the changes.so i searched for any update() refesh() or something like that method but there is none.so it seem i didnt get the concept, can someone help me please?
View 2 Replies View RelatedI have a list (ListView) which displays news items. They contain a image, title and some text. The image is loaded in a separate thread (with a queue and all) and when the image is downloaded, I now call notifyDataSetChanged() on the list adapter to update the image. This works, but getView() is getting called way to often now, since notifyDataSetChanged() calls getView() for all visible items. I want to update just the single item in the list. How would I do this?Problems I have with my current approch is that the list is slow and I have a fadein animation on the image which happens every time a single new image in the list is loaded.
View 2 Replies View RelatedAndroid 2.2 (Froyo) is official and impressive This one doesnt come as much of a surprise, but its huge news. The newest version of Android Froyo, as in frozen yogurt was officially announced, despite the fact that we�ve known about it and its features for some time know. The big take-aways are that it is scary fast (2-5x faster than Android 2.1 for CPU-bound activity), browser Javascript performance is 2-3x faster than 2.1, there is a new data backup API, Android is more enterprise-friendly than ever, and app errors are now reported back to developers for better tracking and improving their apps in the future. The SDK was updated and devices get WiFi tethering as well. All told, its a big step forward for Android.Google I/O has revealed what looks to be the final list of handsets getting Froyo, they include:
Motorola Droid
Google Nexus One
Droid Incredible
HTC Desire
HTC Evo 4G
myTouch Slide
HTC has also suggested that all HTC phones launched in 2010 would get Android 2.2, and that launch dates for the updates would be released on a per phone basis. Most, if not all those updates will occur in the second half of this year. The upgrade to Froyo is desirable for all Android smartphones due to speed increases, updated APIs and services, the V8 Javascript engine, and new features in Android Market.I went to the HTC website and filled in a tech support request pleading that they update the Eris to 2.2 as with its slower processor it could use the speed increase more than newer phones can.
I have a listview in the first page of the application which takes almost a minute to populate. It would be nice if after each entry were generated (in a non-ui thread) the list added that entry - Simply calling refresh in the UI thread with a handler post does not do the trick. I use an ArrayAdapter constructed with a list.

View 9 Replies View RelatedThere's a few apps that I have found that look very useful but are currently not compatible with the Droid (or with Android 2.0 as a whole). I thought it would be good to have a thread to track apps that are worth waiting on the update so we can be notified when the one we want is available.aSettings - No coming update mentioned on Market description. User Comments state that BT & GPS features do not work on Droid.Feel free to add any apps you've got your eye on and maybe someone else will have more info on a coming update. But please, let's keep this down to a list of high rated, useful or fun apps that are currently not supported on the Droid, and not a huge list of all apps. That thread has already been started. This thread is to track the release of the updates on 'would be' top-apps for the Droid.

View 2 Replies View RelatedI got 2 Droid X's last Saturday. If you hold mine and my wife's side by side (in the house), she gets 3G and 3 to 4 bars, while mine is 1X or lower with no bars 90% of the time.
The folks at my local store did a *228, option 2 on my phone and asked me to the same when I got home. Distance between the store and my house is about 9 miles. I did this. Still no help.
So i looked at my wife's phone and the PRL version on her phone is 65169, the version on mine is 52105. Obviously her list sees better towers or something. Is there any way to get my phone to set at that same version of the PRL list? A way to get a specific PRL on the phone?
I get good reception most everywhere else, but the fact that the exact 2 phones have such vastly different reception in the same place is frustrating.
I am using GingerBread for Samsung Note 1. My music player no longer updated the playlist when I added new songs to the phone.I guess there must be crash in the updating of the playlist database. Any method that I can use to determine how the crash happened and then I can try to fix it? (I rooted the phone )
View 2 Replies View RelatedEarlier in 1.6 after I look for a contact and view it and press back. It used to come to that position itself but now whenever I press back after viewing a contact, it goes back to the initial position of contacts (i.e. the contacts starting with letter A).
Example in 2.1, if I view a contact (say named "xyz") and press back, it takes me to the starting list of contacts but no such problem was there in 1.6 version. That is after I press back, it took me to the same list of contacts I was viewing earlier (in this case xyz,xy** etc.)

View 3 Replies View RelatedI currently have a tab layout with 2 tabs, one tab with a list view and one with the option make strings so I can add them in the list view. Both tabs have their own activity because this made the code much more structured, and I dont have to repeat my self later.
Lets say im in the tab that offer me to create an string, and i press the update list button, how do I update the list view without startActivity()? If i use startActivity(), it starts List.java, and instead of displaying the list in the list view tab, it takes full screen, which defies the purpose of the tab view. In other words, the startActivity() steals the focus from the tab view of the list, and sends it fulscreen.
I want to update the activity in my list view tab, without starting a new activity that goes to fullscreen, and doesnt update the one in the tab.
I am on my first Android application and I am on a timeline so details and examples will be useful since my knowledge is still minimal. I want my first screen to present the user with a list of activities to choose from. In my situation it is a recipe app where the user first chooses the type of food, such as, Beef, Chicken, or Pork. I want the application to launch an activity depending on the list item that the user clicked on. I am not sure if I should use a list view, a text view, a scroll view, a list activity, an activity group...

View 4 Replies View RelatedI'm trying to create a multiple selection list where the selection is represented graphically rather than with checkboxes.My list has checkboxes, but I want them to serve a different purpose. I'm using a cursor to hold my data and created a custom view binder for the SimpleCursorAdapter. I did this for the checkboxes and general flexibility.So far I haven't even been able to show one line as being selected. I've enabled multiple selection on the list and denied the children of the list item focusability. I've tried manually changing background color with the position fed in through the list item click listener. But the wrong items get changed and they don't even change to the right color. I've enabled touch focusability with no improvement either.Ideally, I'd like the trackball highlight focus bar to appear in multiple places. But I don't think this is possible unless you use the drawable directly. But I don't know how to find or apply it. My next idea was to have a slim view bar that changes color. But I had the same problem with the wrong item being selected so I never finished trying to guess the index position to see if this would work. My most recent idea is to completely swap out the view for another one if it's selected. But I have no idea how to do this either. I'm thinking of using an array list to store the _id s of the items that need a different view to get around the wierd selection problem. I'm also thinking of passing in the ID field as my from and the selection view as the to for my adapter. Then I'd intercept it with my binder and change the view accordingly. But once again, I'm not sure how to do this successfuly.

View 1 Replies View RelatedI'm trying to tackle a problem that seemingly many Android developers have, which is how to intersperse lists with non-list data, in one big scrollable pane.The model I have in mind is the screen for an individual app in the Market. You have a big description, a list of a few lazily loaded comments, and then some individual items that do different things, like visit the developer's web page, call them, etc. And then in between them all, are nice section headers.Emulating this approach seems to be extremely hard. I've read enough SO answers and mailing list posts to know not to put a ListView inside of a ScrollView, but I want the same effect without using addHeader() and addFooter() with very complex header and footer views. I've tried using a LinearLayout that I stock with views myself, but I can't get the pleasant click effects that default list items have (the orange background, white for long-click, etc.).

View 2 Replies View RelatedI use tabs in my Android application and one of my tabs contains a listview. I'm noticing some weird behavior when I override isEnabled in my list's adapter and then try to use the D-pad to move up and down through the list and to my tabs.If the 0th item of the list is enabled, then everything works as expected - I can move down through the list, and then up again and once I reach the top of the list, pressing up moves focus to my tab.However, if the 0th item is DISABLED (isEnabled in my adapter returns false), then when I press up while position 1 is focused, the focus gets stuck. It doesn't move up to the tab as I would have expected and instead stays on position 1 of the list.
