I look at some posts from the past and it seems that if I add items to the ListView adapter it should update itself and user should be able to scroll to the newly appended items. Unfortunately it's not what I observe. If I append new items to my existing ArrayAdapter I only will see updated results if I rerun ListView#setAdapter again. Doing nothing, invalidating view etc. doesn't do anything. Here's a snippet: SearchItemsAdapter a = (SearchItemsAdapter) list view.getAdapter(); List<SearchItem> values = fetchNextSetOfItems(); a.append(values); // unless I do this - I will not see the update, but if I do - I'll jump to the top listview.setAdapter(a)Code...
View 2 Replies View RelatedThe problem is that notifyDataSetChanged() is not firing up getView() of listView class.
I have an activity class in which i have Gallery Adapter and custom List Adapter (extending base class and overriding getView). What i want is, if i select any picture from gallery then, the list should get updated (dont worry about the data source now, as i am using static images for gallery and static string array for listview). After getting onClickevent from gallery i am calling notifyDataSetChanged via listView Adapter Context so that getView of listView should be called and i can supply another static string array to change the list, but getView of listView is not being called.
If i call notifyDataSetChanged from onClickEvent of listview, then getView of listView is being called. How shall we use notifyDatasetChanged to update the listview using event from another adapter.
I'm developing an application wich has a location push service that start at boot. The main responsability of this service is very simple, just inform the location of the phone based on the *requestLocationUpdates* parameters. I don't care if it's using the network or GPS, obviuosly I'd prefer the most accurate one, but if the GPS is turned off, I don't mind to receive the network less accurate location fix. My problem is that the service isn't working as I expect, since I deploy the app on my HTC Magic, and after a lot of miles driving my car, only the first fix is shown, but no one else. Here some snippet of my service (BTW, I've checked with DDMS that the service is launched at boot):
CODE:..................
I set locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000, 0f, this);
It has an odd behavior, locationChanged gets called every second instead of any time close to 1 minute. Secondly, locationChanged gets called every second for like 10 seconds, then stops completely, the gps satalites icon disappears, then only resumes again when the screen returns from display timeout.
what's wrong? I'm currently on android 1.5.
When I set my HTC Hero to sync with exchange "As Items Arrive", the phone is constantly synching and therefore my battery drains. Even when I turn off the phone, the phone uis still awake since it is constantly checking/sync-ing with exchange. I was under the impression that by selecting this type of sync, the items would be "pushed" to the device rather than the device constantly checking if there are new messages, contacts, or calendar eventsto sync. Is this expceted behaviour, or is there some other tweak I need to do? By the way, I just updatedmy phone yesterdey to the latest firmware, and the issue still persist.
View 2 Replies View RelatedI have an application that runs in the background, and displays an error message via the notifications system. This notification has a pendingIntent that leads back the the app's main screen. On this main screen, I have set launchmode="singleTask". As I understand it from the Android Dev Guide, this should mean that my main activity will only ever have one instance.However, if the user is viewing that activity at the time (or another one within the app), and goes and touches the notification to clear it, it goes ahead and puts another copy of the activity on the stack, so if I hit the back button, it will return to the main screen again (from the main screen).
View 2 Replies View RelatedI have a service that gets updated every x minutes depending on the user preferences. This service connects to a web service and pulls some data. If during an update the user has no connection I register my receiver and start listening for changes (ConnectivityManager.CONNECTIVITY_ACTION), the thing is that onReceive () only gets called on every update instead of firing onReceived as soon as I plug the connection back in. Have I understood the concept of Broadcast Receiver wrong? Is it not suppose to send a notification as soon as it detetcs a change in the connection?

I have a ListView that just contains a CheckedTextView. I have a very simple CursorAdapter that populates CheckedTextViews. When I click on an item, I can see that I am responding to the correct row, store the value in my model and the CheckedText gets checked. However, when I scroll down and then back up again, while I see that the model contains the correct value (in #bindView), calling #setChecked on the CheckedTextView has no effect. Ie All items are unchecked. Code...
View 9 Replies View RelatedHelp me in resolving the below issue. I have three image buttons on screen. All these three buttons controlled under ontouchlistner as below. My problem is, as it is under multi touch event handler like above, it does not detect when touch all three button at a time to try to produce multi touch effect, instead it detects only one imagebutton touch at a time even though i touch all three image buttons. As i am developing this project on Android 1.6 SDK, is there any problem accessing my requirement(multi touch) (or) it is a known issue? I am hoping that, when it works for single button touch, why shouldn't it work when clicking three imagebuttons at a time to produce three logs printed as per my above code? Code...

View 3 Replies View RelatedI have a ListView and an ExpandableListView inside of a TabActivity. I have overridden the setOnItemClickListener for the ListView. I have 2 tabs and one uses the ListView and the other uses the ExpandableListView. For some reason I cannot click on any of the items in the first ListView. If I change tabs to the ExpandableListView and then go back to the first tab it will then allow me to click on the items as usual. Any ideas on why this is happening. Is there some kind of weird focus thing going on? Code...

View 2 Replies View RelatedI'm requesting data from my server and receive a string in the form of 2|bit.ly|1||1| and | should be the separator. I thought the following piece of code should do the work
BufferedReader br = null; ...
br = new BufferedReader(new InputStreamReader(inputStream)); ...
String line; String[] columns; ContentValues values;
while((line = br.readLine())!=null) { columns = line.split("|"); ...
}
But after the line.split("|"); the columns contains 15 elements instead of expected 6. Taking a closer look at it's content reveals that each character in the string was stored in one array element. The code coming from server isn't encoded in any way in in the example I use only ASCII characters appear.

View 4 Replies View RelatedI am making a time sheet program where a user inputs his in- and out-punches. I have a ListView that I am populating from an array of calendar objects. I would like each row to show the day and date then on a new line the time, but I only want to display the day and date if it is different from the previous element.Currently, I am setting visibility in the Base Adapter based on comparisons using position vs position-1 (which are used as indices to the array). This only works if the whole list fits on the screen. If it extends beyond the screen and the user scrolls around the results are unpredictable.To further confuse things, I am setting the color of the times, based on the position, to alternate between green and red (in/out) and it works as expected, scrolling or not.How does Android handle the ListView position when scrolling or what could I do differently to show/hide the day and date?

View 2 Replies View RelatedI have a layout with a ListView that contains EditText objects that can requestFocus() when the user chooses to edit the list item. I make sure to call setSelection() on the ListView when this happens, and then have the EditText request focus and then use InputMethodManager.showSoftInput to show the soft keyboard. However, when this happens, the list view is being resized correctly, but the selected list item remains below the fold and the user has to scroll up. This is working properly on 2.2, but is failing on 2.1. Any ideas for making sure the list selection remains visible?
View 2 Replies View RelatedWhat kind of download speed should I expect with my Droid ERIS? Using my 802.11g wireless router I get around 2mb/sec according to spreedtest.net. I get around 1mb/sec using 3G. My laptop gets around 15mb/s over my 802.11g network. I'm guessing that the difference might be because my laptop has 4gb ram and a dual core and the ERIS doesn't.
View 1 Replies View RelatedI have come to the conclusion that vzw aborted the ota on the 1st 2.2, and not many people have gotten it. It seems at least on this forum that everyone has 2.2 via a forced update. Very few people have chimed in that they got a ota.However, given that vzw is releasing the droid2 on Thu the 12th, I would think that this is going to have the newest froyo, not the version released ota that everyone forced with. Correct thinking?
If that is also true, then shouldn't we be seing something coming out ota for us 2.1 droid 1 users very shortly? anyone have any dates?
I've posted a bigger chunk of the code below. You can see that initially QUOTE was procedural- coded in place. I'm trying to learn how to use declarative design so I want to do the same thing but by using resources. It seems like I need to access the string.xml thru the @R.id tag and identify QUOTE with that string value. But I don't know enough to negotiate this.
