Android :: Animate New Elements In A GridView Being Added?
May 25, 2010My app polls a server every 15 seconds to see if there are any new items to display, then downloads the new items and disposes of the old items so that there are always exactly 100 items in the GridView. Unfortunately, this process can be confusing to the user if they see a page of images change without knowing where the items went.
My idea is that there could be some kind of animation (such as the new items being inserted at the top and pushing the older ones down the list) to show what action is happening. Unfortunately, I have no clue how to make this animation happen.
Is my idea even possible? How would I accomplish this?

View 2 Replies View RelatedAndroid :: Custom Separator In ListView Depening On Content Of Item
Oct 22, 2009I've a ListView with items containing information about places with a rating and the distance to the current location.
The items are sorted into groups:
Group 1: within 500m
Group 2: 500m - 1km
Group 3: 1km - 1.5km
Withing these groups the items are sorted by their rating.Now I put out these items via my custom adapter (extension of BaseAdapter) into the ListView, which works perfectly.
However, what I'd like to do is to put a separator before the each first item of each group. This separator can be a TextView saying e.g. 500m - 1km followed by all the ListView items in that group. Any idea on how to realize this?

Android :: TextUtils Split Is Not Splitting Strings Based On Pipe Separator
Nov 5, 2010I just found after 2 hours of debugging my code for errors that TextUtils.split(String, expression); does not work correctly when I use pipe "|" as the expression. Am I wrong in understanding the method or is this a bug?
It works fine when I give it as a pattern ie., [|].
I also tested it using a few other seperators and they seemed to work fine.

Android :: Getting A Button Along With Gridview?
Aug 22, 2010I have a gridview that is inflated by multiple buttons. I used just a gridview and it worked fine. The grid was in correct order and was centered. Although, I wanted to add a button below the grid of buttons that was different and centered. To do this I decided to section off the gridview and then add the button (therefore it wouldn't be affected by the gridview).
I tried the following code to seperate the views:
CODE:...................
The problem is that this code smushes the gridview to the left and oddly it flips it (Position 0 is ont he bottom right and the last button is on the top left pushed off screen). The following image shows what is the result:
Any idea why its pushed to the left and flipped? Or maybe how I could have just the Gridview with the button on the bottom?
Android :: ListSelector On GridView
Aug 24, 2010I'm trying to use a custom listSelector on a GridView. When I use the default listSelector, I see that it modifies the size of my items so the listSelector display correctly. The list Selector is bigger than my items:
See how when using the default selecto, it make grid items to be resized. Above the gridview I have a LinearLayout with 4 of the same images(ImageView) the GridView contains. http://twitpic.com/2hxkjh
I wanted a custom listSelector, not as bigger as the default (that makes my items smaller), but bigger enough to simulate a border on them without overlap my items content. I'm, not sure if this is an expected behavior, but when I set the listSelector with my own image, I see the selector being fit to my items size. At least my items won't get resized. [url]
Any ideas of how to set a selector that doesn't get resized?

View 3 Replies View RelatedAndroid :: GridView Row Height
Mar 3, 2010I have a GridView that displays images, which are, unfortunately, of different sizes. They are shown in between two lines of text:
CODE:.........
If IMAGE1 is the same height as IMAGE2, everything is fine, but if IMAGE1 is longer than IMAGE2, text2.1 will run into text3.1 (padding doesn't seem to help much, as there's too much of it when images are of the same height).
I know there's a way to stretch the images in the ImageView so they are the same height, but is it possible to keep images as is and set the row height somehow?

View 2 Replies View RelatedAndroid :: Memory Error With UI Elements
Sep 1, 2010In my application I change layouts very frequently with most of the user interactions. Each time when a new layout is drawn, the applications memory size is increasing. I can see this in DDMS. This is absolutely fine. I have analyzed my application with memory analyze tool and it shows that there around 42 Table layouts at some point of time and this number increase as user does more interactions with the app. Now my question is why doesn't the GC collect the stale layout objects. Does GC collect on UI widgets also??? I feel it does but can any one tell me what may be the reason for GC not collecting my UI elements.
View 4 Replies View RelatedAndroid :: Programmatic UI - Setting IDs Of Some Elements
Feb 3, 2010I need to add some parts of my UI programmatically. I'm doing this because I need to set the ids of some elements up in such a way that they can be easily access in a for loop. So far I have this xml:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/attr_row" android:layout_width="fill_parent"
android:layout_height="wrap_content"> <EditText android:id="@+id/attr_name"
android:hint="Attribute" android:layout_width="0dip" android:layout_weight="2"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<EditText android:id="@+id/attr_val" android:hint="Value"
android:layout_width="0dip" android:layout_weight="3"
android:layout_height="wrap_content" android:inputType="textPersonName" />
<ImageButton android:id="@+id/drop_attr" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:background="@drawable/btn_delete_states"
android:layout_gravity="center_vertical" /> </LinearLayout>
At the moment, I inflate this xml five times like so:
for (int i = 0; i<5; i++) { LinearLayout attrList = (LinearLayout) findViewById (R.id.attr_list);
LayoutInflater inflater = getLayoutInflater();
View row = inflater.inflate(R.layout.attr_row, null);
LinearLayout extraAttr = (LinearLayout) row.findViewById (R.id.attr_row);
ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(
ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
attrList.addView(extraAttr, i, params); }
The link below shows two pictures - the layout hierarchy and the result in the emulator. http://picasaweb.google.com/bengoldcross/Android?authkey=Gv1sRgCJ785I...
As can be seen, the xml is inflated five times successfully but only one is actually displayed. Inspecting the hierarchy viewer a bit more explains why. The layout being displayed is at location x=0 y=111 all the others are being rendered at x=320 y=111. It would appear they are being displayed a) off screen and b) on top of each other. So, why are they and how do I stop it from happening?
Android :: Sharing Elements Between Applications
Jun 10, 2010Here's a quote from Android's Dev Guide: A central feature of Android is that one application can make use of elements of other applications (provided those applications permit it). For example, if your application needs to display a scrolling list of images and another application has developed a suitable scroller and made it available to others, you can call upon that scroller to do the work, rather than develop your own. Isn't it a bad practice to make an app dependent on other apps?

Android :: Update SurfaceView On-the-fly With New Elements
Aug 5, 2010I have a database filled with records in the following format: . What I want my application to do is select records from an external database, and display those records on the phone screen using a SurfaceView.
Currently, I have an Activity, and a Service responsible for the record-gathering portion of the application. The Activity passes an intent to the Service, and the Service responds by returning the records that need to be displayed. The records are stored in my program as instances of the Data class, and merely have the screen-coordinates of where the element should be drawn in the View (I am just drawing a circle for every record in the DB).
For the sake of brevity, I won't include the service but I will include a skeleton of the Activity class and the Data that I wish to display.
CODE:.................
The problem that I am having pertains to the SurfaceView. I realize that many people are going to suggest that I use just a regular View, but my application involves a lot of elements, so a SurfaceView would be much more suitable for my needs. Below is a skeleton of my SurfaceView class that contains a nested class to manage the threads.
CODE:............
The problem that I'm having is that once I make the initial call to the Panel class, I'm going to be getting new records from the service, and consequently, my Info Map data-structure is going to get updated. However, my Panel class just gets stuck in a loop and never receives any new Data objects. All examples of SurfaceViews I've found have involved updating them methods within the SurfaceView class itself (e.g. touching the screen and creating a new image, etc.) Sadly, I'm stumped on this particular problem. Is there a better approach for designing my Activity/SurfaceView interaction? Is an additional View required?
Android :: Example To Layout Elements Programmically?
Mar 9, 2009From http://d.android.com/guide/topics/ui/declaring-layout.html, it said "Instantiate layout elements at runtime. Your application can create View and ViewGroup objects (and manipulate their properties) programmatically."
Can you please tell me how/where I can find example for that?
For example, how can I convert the following layout into Java code of my MyWidget. So that when I put "<MyWidget...>" in my layout xml file, it will automatically build a Gallery inside the MyWidget? code...
Android :: Looping Through Interface Elements?
Sep 2, 2009This is probably a very "newbie" question as I'm relatively new to the android sdk, but figured this would be good place to ask.
Say you have a layout with several textviews that all have sequential IDs (ie, tBox1, tBox2, tBox3, etc).Is it possible to reference each box in a loop? Something like:
do { iCount++; View tvBox1 = findViewById(R.id.tBox[iCount]); }
Android :: Json Changes Order Of Elements / Fix It?
Oct 13, 2010I am trying to send a list of objects from an android mobile phone app to a j2ee webserver.
I create json objects and then put the objects into an jsonarray(in an order) and then send it. I am able to receive the jsonarray on the server, obtain the objects individually too, but the order of how I inserted the objects into the jsonarray is different compared to the order present in the received array. The order of elements plays a crucial role in my data processing. Could somebody please tell me a workaround for this.
