What is the way to fresh an activity without calling finish- >startActivity all over again?
After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?View 2 Replies View Related
I have a START and STOP button in the main screen of an App. there are some GUI and threads that are instantiated when I click on START. When I click on stop, I want everything to be stopped and the activity should come back to its origin state. To the state that is exactly same like when launched (when we tapped on App icon in mobile).Is it possible to do this? I tried with finish() , this killed the app and exited . I don't want to exit from main screen. rather, on clicking STOP I want app to come back to origin or born state.View 2 Replies View Related
I have one activity. OnCreate the activity gets the source (html) of a web page to a string and presents the result (after parsing it a bit) in a textview. I would like the activity to reload/refresh periodically to always present the latest information.View 1 Replies View Related
I have created map view using XML layout in MapActivity and want to use this map view in another Activity group. I got mapview object in Acitivity group using GetWindow.Decorview(), MAP view is also displayed in the same layout of Activity Group. But without any image, only white background with some grid. Map view is not getting refreshed when i scroll on Map view. But if i launch independently MapActivity , i am able to see the map and it is getting refreshed when i scroll on the map. May I know how can i use and refresh Map view in an activity group? As Mapview can only be created/inflated in MapActivity.View 2 Replies View Related
I have an Android Activity with a RelativeLayout and I have implemented the following method to prevent the activity from being recreated on change of Orientation:
I am obviously not doing anything in this method, but it worked perfect when using a LinearLayout. Now however, using RelativeLayout, my layout is all messed up when changing to landscape orientation.

I am trying to root my EVO and getting stuck at a certain point.I am following the instructions/videos found here:[GUIDE] How to root Android 2.2 on the EVO 4G - xda-developers.I have followed the directions successfully up until I am instructed to me to boot with HBOOT USB and then remove the battery to restart, and run reflash.exe.I am stuck running unrevoked (reflash); the phone does not display the console but rather boots normally. The first time running reflash seems to be working normally until it reboots and searches for the phone, at which point hangs. Any attempt to restart the process will hang at Pushing Recovery Image. I have waited patiently over 10 minutes for each.After the phone fully boots it my computer lists in Device Manager now lists my phone under ADB Interface.I am using windows 7. I have USB debugging I have removed HTC sync (still have HTC drivers installed) and installed the Android Bootloader Drivers. I also am running reflash.exe as Admin.View 12 Replies View Related

I've got a bunch of live wallpapers for sale, and have a lot of 1-star comments that just say "Doesn't open". This is because there's no launcher activity, so the open button is greyed out after download. I'm attempting to fix this by including an activity that explains what to do, and I'm trying to avoid useless app clutter by disabling that activity once they've successfully used the wallpaper. This seems to work fine, the problem is the app icon doesn't go away right away. It stays in the app drawer and if you tap it you get a "this has been disabled" message. Eventually it will be removed if the phone is rebooted or if the home app is restarted. I'd like to clean this up. Is there a way to tell Home to refresh this list, or to otherwise tell it to remove the icon from the listing? It seems a bit rude to process kill Home for this purpose, and clearly something like this happens when an app is installed/ uninstalled.View 2 Replies View Related

I have an activity with a HorizontalScrollView. When it opens, I start filling this view (or rather, a container layout inside it) with another views. This is done from another thread by using handler.post.
The views are added in bunches of 15, and when there are no more views to add, I start updating them with new data (this is a kind of streaming data from a server).
The problem is that the scrollview is empty until all of the views are added. As soon as they are all added and start updating, the scrollview gets drawn.
How do I refresh it in the process of adding views? I don't want the screen to be empty for 3 seconds while all of the views are added.
I would like to make a Linear Layout that was created from xml invisible, and another Linear Layout visible to replace it. The replacement layout starts out as invisible. When I make the originally visible layout invisible, it still leaves space for it on the screen. How can I refresh the screen so that space is gone?View 2 Replies View Related

On paper its a good little app bringing together twitter and facebook. My issue is that it doesn't refresh on its own? But the peep app and the facebook app's do? Let me know if this happens with you or if I am just missing one of those hidden settings.View 16 Replies View Related

I have a strange problem with StateListDrawable or maybe (probably) I'm missing something. I created a test application for it and the same problem occurs. So, this is my StateListDrawable resourse in file test_selection.xml
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/ android"> <item android:state_selected="true"> <shape android:shape="rectangle" android:background="#ff0000"> <corners android:radius="10dp" /> <gradient android:startColor="#ff5555" android:endColor="#ff5555" android:angle="0" /> </shape> </item> <item android:state_selected="false"> <shape android:shape="rectangle" android:background="#eeeeee"> <corners android:radius="10dp" /> <gradient android:startColor="#eeeeee" android:endColor="#eeeeee" android:angle="0" /> </shape>.............................
When Activity starts I try to set the state of my Drawable (the StateListDrawable) with the value SELECTED. It seems all very simple.... but the problem is that the state is not shown. If, later, I click a button and execute the method updateView() the state changes. Where is my problem? Where am I wrong?

In my app, I have different activities with listviews. The datas come from a server with a REST method, and it's only done once, when I start the application.
The pattern that I'd like to set is to precharge all the listviews with the JSONs that I already have in local, and in parallel, launch a thread that get the new JSONs files with my REST methods, and then update the listviews.
For now, when I start the app, I parse my JSONs files, and build all the lists of objects. I access them later in a static way, from my lists adapters.
So I would like to know the best way to launch this REST thread, and update the listview. Should I use AsyncTask ? A service ? and then, when I update my local JSONs, I have to re-parse them, updates the lists of object, and call in my adapters NotifyDataChanged ?

I don't need a strict code related answer I just need somebody to tell me what I am missing.My application has to retrieve from a web service (xmlrpc) the positions of some users I know and update their position on a MapView.So I decided to use a Service and an Activity extending MapActivity to show results.
I thought about two solutions:
I ) start the service and make it ask every minute for these positions and send them to the activity as a bundle via intent. (This didn't work out well, since once shown I couldn't find a method to let the activity continue refresh itself until she stop receiving intents+data from the service)
II ) Incorporate a thread within the activity which starts the service via context.startService(...) every minute. And the MapUI refresh itself once the service send back an intent and stop itself. (Maybe I will fall in the same problem category as before I haven't tryied yet).
I am also giving directions (via maps.google ws) in this way I'd like to refresh only users positions on the map and save the route.What Am I missing do you have any suggestions? related to activities/services internal mechanics, don't know launch modes, use broadcast receivers or intent filters?

I'm currntly struggling with an Android problem whose answer is maybe simple.(I'm new in Android developing)I have a main activity that builds a TabHost with two Tabs (each represents another Activity)As far as I know I can't receive broadcast messages within an activity - so the only thing I could do is to start a new activity out of my Broadcast Receiver. But instead I want to change my Tab View or show the alert.Are there any possibilities to access an existing Activity from a broadcast receiver class?View 1 Replies View Related
I 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.
So my list is not refresing/updating altough all cursors all results are updating.
Had my Desire for about a month now, and am loving it, but have run into a problem over the last week or so. My friend stream app has stopped working. The widget will never refresh, and whenever I try and go into it an error: "The application Friend Stream (process com.htc.friendstream) has stopped unexpectedly. Please try again" just keeps popping up, and I have no choice but to force close. I've been hearing rumours it could be another app I've installed that's causing it.View 22 Replies View Related

The droid as two email apps built in that I see. One is for gmail only and the other for any other email out there (excluding yahoo). The other one also one can be setup to use as a gmail account. What is the benefit to setting up the gmail app to only gmail and not just putting gmail on the other one so all you email accounts are displayed in one location? Do both of the settings push the gmail to your phone or does your phone have to fetch on one of the settings? Also, is there a way to set up your email to only fetch once every 12 or 24 hours? I think the only options I see is up to 1 hr or manually.View 7 Replies View Related

What is the best way to display a database queries results on the screen using ListActivity? I need the db queries to run in the background and I also need to be able to make different queries and refresh the screen according to the query result. I am using the ListActivity class with a SimpleCursorAdapter in order to display the db queries result on the screen. At the moment, I am doing the db queries at the background using AsyncTask, when getting the results I want the list to be updated immediately, but I can't find a good way to do it. It worked only when I used the changeCursor(cursor) function to set the adapter to a new cursor with the new results. But I don't think this is a good solution since it seems to stuck the UI for a while. I also found some posts about notifyDataSetChanged() but I am not sure if/how/when I should be using it with a SimpleCursorAdapter to make the view refresh.View 2 Replies View Related
I am having some difficulties getting my emails. I have my Hotmail account linked to my phone. When I first got the phone, email came lickety split. I have downloaded 17 apps (or widgets, whichever you prefer). Now I don't get any email at all unless I refresh my inbox on my Eris. They have been up to a day old when I decide to try refreshing my inbox and, what do you know, they all pop up! My oh-so-famous "enable always-on mobile data" box is checked.
Is there any way to search for a program by typing in its name?
