I am developing an android application where I need to manipulate the background image of the rows in listview on certain conditions. Initially when the listview is loaded all works properly. But when I scroll down to the listview and come up again the background image changes. Can someone tell me the reason why its happening so?

I am using this image http://android.amberfog.com/wp-content/uploads/2009/11/001.png from this page: http://android.amberfog.com/?p=247 to test dithering on my android phone. However, when I used the android:dither="true" option in my XML file and when I added android:tileMode="repeat" as well, it did not make any difference and the image did not change at all. Any idea as to why this is happening? Does dithering depend on the device being used or something like that?

I haven't modified the program in anyway from Exercise 3 solution (http://developer.android.com/resources/tutorials/notepad/index.html). Any ideas why this is happening?
How to add Image in ListView.

View 1 Replies View RelatedOur application is defined to launch a SplashScreenActivity from Intent { action=android.intent.action.MAIN categories= {android.intent.category.LAUNCHER} . After the SplashScreenActivity does its work, it launches another intent to launch MainMenuActivity and finish() is called on SplashScreenActivity.
When we run our app for the first time on our phone, the SplashScreenActivity launches OK, and correctly launches the MainMenuActivity.
However, if we kill the app using TaskKiller, LOGCAT indicates that the application has been killed. I can't debug the app, because launching it from eclipse with the debugger makes it work OK, because it reinstalls the app. Perhaps there is a way to launch the app without reinstalling it?
Here is the Log of us killing our app...
When we launch the application again, the LOG messages for SplashScreenActivity are not logged and it looks from LOGCAT that Android is launching the MainMenuActivity instead. Here is the log...
Can someone Romaine, Diane help us understand what is happening? We saw this happening because some variables are initialized in SplashScreenActivity that aren't available with MainMenuActivity and we were getting NPEs.
ListView Question! I know it's possible change the row color, but it's possible to put some imagem on background? And if yes, it's possible to create an imagem 1px and repeat-x or repeat-y like CSS?

I have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

View 6 Replies View RelatedI have a ListView with a lot of "rows". In each row, i have one TextView with a background image. When i scroll, the images of the rows mixes... they jump to another row with the scroll.
In have tried android: scrollingCache="false" and android:cacheColorHint="#00000000" but nothing.
The images are loaded dinamically.
Part of my layout:
CODE:.........................
And part of my code:
CODE:............
"avatars" is a cache of Drawables. any idea?
CODE:.............
This is my current row. If I created a .JPEG, and I want that to be for each item...how would I change this .xml file? Where would I put the image? In Assets?
I am using a LinearLayout to display some Text and image. I have the images at drawable/ and i am implimenting this with ListActivity with some onListItemClick functionality. now i wants to change the image for the rows which are processed by onclick functionality to show the status as processed. can some one help me in this issue to change the image at runtime.
The following is my implimentation.
CODE:.........
And main.xml is :
CODE:.........
I thought to add the field to DB. but i was unable to know how to change the image with code. can any one provide me an example for drawing image with code and change it based on a condition at runtime.
Ex: If I click phone and attempt to dial/search for a number, it just scrolls down by itself.
This is very irritating. How do I prevent this from happening?
I use this code in my getView:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listrow, null);
}
Order o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
ImageView thumb = (ImageView) v.findViewById(R.id.icon);
if(o.getOrderDrawable()!=null){
thumb.setImageDrawable(o.getOrderDrawable());
}
else{
tt.setText(o.getOrderTitle());
}
}
return v;}
The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.
I have created listview by using arrayadpter i add arraryadapter to listview containing string array but i m unable to add icon to eatch listitem.

This occurs on sksboards.com forum.
I am loading a listview dynamically. I have set a .9.png image as row background image. The main purpose of using .9.png image was to extend the height of the image dynamically according to the contents of the listview. But, the image is not getting extended. The contents which can be displayed within the height of the row are being displayed and the rest are being cut.
View 3 Replies View RelatedI am using a ListView to display my custom item layout, which may contain some TextViews and an ImageView.
This is the item layout I made (post_item.xml):
CODE:........................
I don't put the ImageView initially in the xml layout, but I will insert it when I need to the FrameLayout programmatically (I also put another views in it when needed). So, there will be some items which has ImageView in it and which don't.
I get the image to fill the ImageView from the Internet (through URL), decode it as Bitmap, and keep it as a Bitmap variable in a class represents the custom item layout (class PostItem).
When the activity shows for the first time it looks fine, but as I scrolled through the items then a problem showed up, the items which shouldn't show any image show the image from the other item which should, although they don't have any ImageView (because I didn't insert it).
I am using SDK 1.6 and the emulator. Haven't tried it in real device because I don't have it.
Here is my code for the Adapter:
CODE:..............
And this is the code to prepare the items:
CODE:.........................
Is this the bug in the emulator or there is some mistake in my code (probably memory problem for the Bitmap)?
Has anyone else notices that when using the Android keyboard the predictive text will randomly capitalize words? Its kind of bugging me and I've rooted my phone, so is there anything I can do to stop this from happening?

I got this class, and nothing inside the onCreate is happening? Does it not automatically get called upon initialization?
Code is below.
CODE:......................
Doing this results in a "application has stopped unexpectedly. Please try again". If I initialize the string to some set of characters instead of null, it'll just stay that way. Should it not do what is inside the onCreate() and make that change?

View 7 Replies View RelatedI am using Handcent on my Droid. I have it all set up to use a different tone to remind me of messages (at least I think I do). Instead, it just plays the initial tone as a reminder.
For example, when I get a text message:
<wild bird> -one minute- <wild bird> -one min- <wild bird>
But I want:
<wild bird> -one minute- <honk> -one min- <honk>
Where "honk" is the reminder sound. Anyone know why this might be happening?

View 2 Replies View Relatedi have a droid eris and it does random things. For instance when exiting the browser it goes from home all the way to the left and when i go to slide it back to home it stops and slides it all the way back to the left. It will randomly call people, freeze up, hang up on calls, shut off while in a call, and change pages while on the browser, freezes up in a call so you cant go to different things while talking. Ive done a hard reset 3 times and and soft reset many of times. I dont want to do a master reset and lose everything. Is that my only option if so is there a way to backup the files and contacts on my pc. I have taken it into verizon many of times and all they say is to reset it and nothing else.
