[android-developers] Setting filter on List using Text Watcher
Hi All, I have a ListView, which is having data in the form of HashMapString, String. I am populating the list as SimpleAdapter adapter = new SimpleAdapter(ctx, myData, R.layout.my_layout, keys, ids)); listview.setAdapter(adapter); In my_layout.xml, I have set 2 TextViews(which will be the row of the listview). So the list row will look something like Abc AbcData Xyz XyzData Now, I want to include text filter this list. For this I have impleted TextWatcher, private TextWatcher filterTextWatcher = new TextWatcher() { @Override public void beforeTextChanged(CharSequence s, int start, int count,int after) { } @Override public void onTextChanged(CharSequence s, int start, int before,int count){ adapter.getFilter().filter(s); } @Override public void afterTextChanged(Editable s) { } }; @Override protected void onDestroy() { super.onDestroy(); filterText.removeTextChangedListener(filterTextWatcher); } The filter is working ok. But the problem is I am getting 2 rows for each search. Say if I type 'A' I am getting 2 rows(same content though in the original list there is only one row) Abc AbcData Abc AbcData I assume that it is filtering first on Text1(i.e. Abc) and then on Text2(i.e. AbcData) and hence I am getting two rows. So can anyone advise how should I tackle this problem and get only one row.

Thanks Kostya. I got your point. However in my case as i am setting background, its kind of ok for me to use button or textview. my btn is also luking ok my main prb is to change the image on click so tht usr cud knw which date has been clicked. even when i return from previous page the according to the result of the next activity, i want to hightlight tht particular day I can try to implement sm logic to change the color of the selected day. but it is difficult to change the color whn coming back frm the called activity(becaz i dont knw the image of the returned date). becaz depending upon day is holiday, or have a event, i am showing different image.

[android-developers] Re: capturing Home key event at application level
Perhaps this (garbage collection on background applications) actually does happen but just isn't documented, then freeing memory before going into the background is a useful thing. Yes thats why i want to freeing memory just before going into the background but I am not getting callback which will get called after pressing home key. However after reading your reply, now i also have doubt even if i clear memory ( initialized it with null), it will call garbage collector or not but it is more better than not releasing memory at all. if in case garbage collector get run after assigning null, my purpose will be achieved.

From what I can find in the documentation, it's not clear if this can reduce memory consumption. An application sitting in the background is presumably not running any code and not making allocations, so there is nothing to trigger garbage collection (and cause the heap allocated by Dalvik VM from the Linux kernel to shrink). Later, if Android runs out of global memory, it's documented that it just starts killing background processes in their entirety. It's not documented that there is any attempt to run garbage collection on background applications' heaps and shrink them to free up global memory.

[android-developers] Progress Bar without a dialog box
Hi, In my application, I am fetching data from server. During fetching response and parsing it, I want to display a progress bar(Like spinner) but without a dialog box. If I am using ProgressDialog then it is also displaying Dialog box. I had also tried Progress Bar but I have to include it in the XML. My problem is this that I need to display progress bar in almost every screen of my application and only at the time when I am fetching data from the server. So I think, I shouldn't include it in XML of every screen. Please help me. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Cache size and Heap size
Thanks Dianne. I have some more queries. 1. I am refering to the Cache memory which is return by getCacheDir function. Is there any limit that per application only this much Cache memory could be used? 2. If Cache memory is same as normal internal data storage space then is it dependent upon the mobile's phone memory? Is there any % amount of total internal memory which could be used as Cache memory. 3. Heap Memory: I had tried functions like Debug.getMemoryInfo which returns Debug.memoryInfo object and also ActivityManager.getProcessMemoryInfo function which returns ActivityManager.MemoryInfo object. Now there are different functions in MemoryInfo like getTotalPrivateDirty or getTotalPss(). I am unable to understand use of these functions. What is the meaning of Total Private Dirty memory or total PSS memory? Which one of them returns Heap memory? Is there any limit per application to use heap memory?

[android-developers] Re: Use of Service component?
Thanks Kostya, for sharing this information, I need one more information: If my service class after complition wish to update the activity class, how can we do it? I am just a beginner and haven't much knowledge of android. On Sep 1, 1:24 am, Kostya Vasilyev kmans...@gmail.com wrote: One more thing: Android uses the same Linux process for your WidgetProvider as well as service that updates the widget (again, I'm assuming you followed the Wikipedia sample). The WidgetProvider will be created and invoked as necessary, this, in turn, should cause your service to be started when you call startService(this, UpdateService.class). A task killer is likely to interfere with the first part of this sequence - i.e. preventing the WidgetProvider from responding to update events in the first place. -- Kostya 31.08.2010 23:50, Kostya Vasilyev О©╫О©╫О©╫О©╫О©╫: If your code is set up along the lines of the Wikipedia sample widget (which it seems to be), and the widget's onUpdate invokes the service with startService, then everything should be fine already. StartService will, obviously, start the service as necessary. If there are still problems updating the widget, ask your user to add your service to the task killer's exclude list. Better yet, try to educate the user about the evil nature of task killers, perhaps he/she will stop using them altogether. -- Kostya Vasilyev --http://kmansoft.wordpress.com 31.08.2010 22:14 О©╫О©╫О©╫О©╫О©╫О©╫О©╫О©╫О©╫О©╫О©╫О©╫ Alex maroeb...@gmail.com mailto:maroeb...@gmail.com О©╫О©╫О©╫О©╫О©╫О©╫О©╫: What is the correct way to ensure that a widget update service is restarted if it has been killed?

[android-developers] Use of Service component?
Service Component is used to do some task which can be done without user interaction. But for that we have to run a thread in subclass of the Service. I think we can create a thread in Activity class itself then what is the use of Service component? Why don't we create another thread and write the non interacting code in this thread. -- You received this message because you are subscribed to the Google Groups Android Developers group.
