Is it possible to have a list activity that dosen't finish? i.e. if you scroll to the end of the list then the start of the list begins again? It's be best if you could also disable the scroll bar.

I have a list Activity 4 which i have extended the BaseAdapter and the getview looks like this.
public View getView(int position, View convertView, ViewGroup parent) {
View row=null;
for(int i=0;i<10; {
row = convertView;
if(row==null) {
LayoutInflater inflater = mContext.getLayoutInflater();
row = inflater.inflate(R.layout.parsed,null); }
TextView id = (TextView)row.findViewById(R.id.id);
id.setText(idvector.elementAt(position));
TextView photo = (TextView)row.findViewById(R.id.photo);....
I have some problems when creating a ListActivity.
I have a listview and some other widgets and my listview is filled with a custom adapter.
You can see the images of this activity here:

Now the problem is. I have a scrollview and all the other views and widgets are placed inside of it. As you can see on the image, I don't see all of my 6 comments (that is the list). When i don't place the scrollview the height of the list is perfect (i have set android:layout_height to wrap_content (to my listview and parent LinearLayout). This is perfect but I have other widgets under the list and when the list reaches the bottom of the screen I can't to scroll to view my other widgets..
How can I fix this? I can set the height of the linearlayout manually but the problem is that the height doesnt has to be the same all the time (it loads the commens from my web service).. It has to fit the height of all the comments (like wrap_content normally does..)
Here is a part of the code with the layout and listview..

I got a ListActivity. I update the activity using onContentChanged() API. My problem is that each time I call the above API the list scrolls to the top. Is there any easy way to turn this "feature" off?
View 1 Replies View RelatedI would like to run the Android Camera application from my development board for about 2 hours continuously.
I want to disable the phone lock screen that comes and shuts down the app.
I am continuously running a thread in my activity which fetches lat/ lon information and the overlays on the map are updated dynamically through a handler. The overlays can be varying in number and can change dynamically. The thread is interrupted in onPause().
I am over riding the onTap() method in my Itemizedoverlay, where I want to call a dialog or may be start anothrer activity which describes that particular overlay item.
Every time I click on the moving overlay my app force closes.
I am basically using same onTap() method in http://developer.android.com/resources/tutorials/views/hello-mapview.... .
If it is only a Toast message and not starting a dialog/activity then it works fine.
I'm trying to figure out how to continuously update the coordinates of the trackball. Right now, I just want to write the values on change to TextViews to understand how it works.
I've been looking at the onTrackballEvent. Right now, I assume that each event passed as an argument to it should be seen as a complete event, that is from the start of the trackball movement to the end. Is this correct? Because if so, the values of x and y will be the same during the execution of the onTrackballEvent body. If this would NOT be the case, I could just use a timer and update the values at a regular interval..
So either I have to somehow interrupt the onTrackballEvent call and write the values, repeatedly over and over again while it is still moving, which seems weird, or...well this is pretty much were my Google search skills and Android knowledge comes to a halt.
I am using soundpool to use sounds in my app. One of the sounds i need to play continuously in background. any example how to do this ?
soundPool.play(soundPoolMap.get(sound), streamVolume, streamVolume, 1, 0, 1f).
I'm trying to use the Media Recorder to have my application continuously record audio in memory (to a circular buffer of a known size). Indeed, I'd like to be able to play back the past 10 seconds of recorded based on a certain event in my program. Much of the Media API is designed to linearly record audio to a file. Has anyone an idea on how I could best do this with or without the default API?

But when I go back to the Market Downloads it is still displaying the animated 'Installing' bar. I have tried a power off reset, even removed the battery for a few seconds but when I return to Market Downloads the 'Installing' message is still there.

I have an empty FrameLayout and I want for a certain event to being continuously repeated until the finger leaves the display.

I have one simple question regarding Java TimerTask. How do I pause/resume two TimerTask tasks based on a certain condition? For example I have two timers that run between each other. When a certain condition has been met inside the task of first timer, the first timer stops and starts the second timer, and the same thing happens when a certain condition has been met inside the task of second timer.how do I pause timer1 while running timer2 and vice versa while timer2 is running? Performance and timing is my main concern as this needs to be implemented inside another running thread. By the way I am trying to implement these concurrent timers on Android.
View 4 Replies View RelatedI bought a HTC hero (white, in UK) a few days ago - It worked totally fine until today! Now it switches itself on & off continuously! Unless I take battery off! The only way I can rectify the problem is if I take the SIM card out altogether, then it seems to stay switched on without a problem! I have also tried another SIM card just incase I had a fault with my SIM but it does just the same.

View 2 Replies View RelatedHow to stop Flickr from running in the phone and how to bring it back after disabling the app? I installed Flickr on my Droid Rezound. I didnt know it was already on the phone. I installed the Google Play version on top of the already installed version on my phone. I tested it out and decided not to keep it. I uninstalled the Google version and found the app was still trying to upload photos. Did some searching in the phone and disabled the phone version. After that it still tries to upload the photos. I signed out of Yahoo and Flickr and it still tries to upload. It's not that I care if the pics upload, but when I've taken lots of pics the upload gobbles battery life.
View 3 Replies View RelatedI've tried calling Verizon about my Droid 2 resetting almost nonstop. I can't make it through a phone call or browse the web or anything without it resetting. I had had my first one for less than a year when it started acting up. Verizon tried sending me a replacement but it did the same thing. Now I'm on my third Droid 2 in less than a year and it's resetting on its own also. I haven't downloaded any apps on this newest replacement so I don't know what's causing it. Could it be my battery or SD card? I'm just at a loss and I really don't want to get a new phone already.
View 9 Replies View RelatedSo today I was driving in my car with my phone on the space between the gear shifter and the console( Lexus ES300- forget the name of the place). Anyway, I had it there and when I touched it, it was hot to the touch. I checked the Temp and it clocked up to 47.8 degrees Celsius (wish the standard HTC battery widget came with an option to change to Fahrenheit). I was alarmed as it has never gone that high before and I was not doing anything with it while driving (as that would be stupid). An hour later I was driving again and plugged it into the car charger to charge it and it shot back up to mid 40's range. Could it be the sun reflecting off of the plastic?

i am developing an android based application "Route Tracker For Special Person".
well i am working with Google map api v2 and till now i have include map in my app and mark some places and further work i need to know this... During traveling When user reach at specific location let say user reach at location A, i have to call an event. e.g My app should find current locations continuously and automatically and match with locations that i marked ( how can it be done) and when it matched, event should be called.
After attempting to download a few apps (actually a bunch of language apps), ie, after successfully downloaded only 5 of the bunch that I selected on Google Play, my Evo V 4G Virgin crashed and restarted.
After this shutting down and restarting repeated a few times, I uninstalled all new apps and force stopped and disabled Google Play... to no avail.
"Google Play Store is not responding. Would you like to close it?" message pops up twice and then the phone shuts down and restarts again continuously.
Did I get a virus?
These are the apps that downloaded before it started to do this:

BTW, after a couple of months I had the phone, every time the phone is restarted about 2/3 of my apps blank out (ie, replaced by the generic green Android icons) for a few minutes before they are all reloaded up. Why is this happening? Is this normal? Is this related to what's happening?
I just got a Dell Venue 8 which comes standard with Android 4.2.2 and it continuously reconnects to my wifi network. It just cycles through Connecting -> Authenticating... -> Saved, Secured with WPA and then starts over again with connecting. All other devices work on the network so it isn't the router. I've tried to toggle wifi on and off, toggle airplane mode on and off, forget and reconnect to the network, and turning it off and on and nothing has corrected it. I haven't found much googling this issue or on Dell's support page.
View 3 Replies View RelatedI'm trying to create an application that has 3 tabs. Under the middle tab should be a ListView. It starts up fine (on the left tab) but when I click the middle tab it crashes.
The other two tabs are static data specified in the main.xml file. But the middle tab, I try to create dynamically. Here's the code from the main onCreate function:

ContactListActivity is defined this way:
public class ContactListActivity extends ListActivity { ...
I get the feeling that I'm supposed to create the Intent with something like Intent.ACTION_VIEW but this is where I get lost. If this is the problem, I could try stuff until it works, but I'd prefer to understand why.
Or is ContactListActivity supposed to override something ?
I have a problem with rotation, during my ListActivity is loading data from the network. To do it I use a background thread which recovers data and put them inside an ArrayList. While this thread works, there is Progress dialog activated in foreground. For the rotation I use the method with onRetainNonConfigurationInstance() to save my ArrayList's state. After android calls this method, I call dismiss() on the progress dialog on onStop(). Then the activity is created as new with onCreate(), but it use the getLastNonConfigurationInstance() to recover the ArrayList's state. Now, my problem. If I rotate from portrait to lanscape when the download is terminated and I see the data in portrait yet, everything is ok. If I rotate during progress dialog is showing I have two cases: 1- onRetainNonConfigurationInstance() saves the arraylist fully recovered, the thread terminates and everything is ok. 2- onRetainNonConfigurationInstance() saves the arraylist empty, i think the download isn't finished yet. The onCreate is called and my list is empty, the thread terminates, but i don't see anything in my list. If I am in this case and I still rotate from landscape to portrait now I can see my list full with all the data. Why? Where am I wrong?

View 2 Replies View RelatedI want to create a custom list view in my application. I want it to lay over the top of the application screen, with portions of the screen not filled by the listview showing the underlying application. I've been reading about ListActivity, how it can be started to handle item selected callbacks. I've also read about people simply inserting onClick handlers into the listview as it is drawn. I'm trying to decide the best way to proceed. Is it "dirty" to attach onClick handlers to the rows of a listview? It doesn't seem like the best approach, for instance, it only handles Touch Mode, not the DPAD clicks. This approach doesn't seem like what the architects had in mind. On the other hand, I don't see a good way that I can start a list activity and still have access to all the application variables I need. Do I pass the application in the context and refer back to it from even handlers after casting the context back to it's original class?

View 3 Replies View RelatedI have an ListActivity that I wan't to add a logo to at the top above the list but I'm unsuccessful. This is what my layout looks like at the moment.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/logo" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false"> </ListView> <TextView android:id="@+id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/list_empty" /> </LinearLayout>
Then I add an drawable to the ImageView logo in onCreate. I've managed to show either the ListView or the ImageView but never both of them in the same LinearLayout. Is it possible to add other views together with a ListView?
