I have a simple ListActivity midlet. It populates the list using a String array which is passed to the setListAdapter method. code...
However my question is, how is it possible to modify the properties of the list so if I know "etc" and "dev" are directories and I want to change the text colour to reflect that it is a directory how can I do this ?
Can anyone point me to any API's ?

How can I add/delete/modify values in "default.properties" for Android.
View 3 Replies View RelatedI'm using BaseExpandableListAdapter, and there is a drop-down button (looks like an arrow) on the left side for each parent item to indicate that you can expand that item to view child items. The question is: How can I change the properties of that drop-down button such as its position? I basically want to move it a bit lower in each parent item.

View 2 Replies View RelatedWhat 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.

I would like to write a rather simple content application which displays a list of textual items (along with a small pic).I have a standard menu in which each menu item represents a different category of textual items (news, sports, leisure etc.).Pressing a menu item will display a list of textual items of this category.Now, having a separate ListActivity for each category seems like an overkill (or does it?)
Naturally, it makes much more sense to use one ListActivity and replace the data of its adapter when each category is loaded.My concern is when "back" is pressed. The adapter is loaded with items of the current category and now I need to display list of the previous category (and enable clicking on list items too)
Since I have only one activity - I thought of backup and load mechanism in onPause() and onResume() functions as well as making some distinction whether these function are invoked as a result of a "new" event (menu item selected) or by a "back" press.This seems very cumbersome for such a trivial usage.Am I missing something here?
One thing driving me crazy in Android is if you start typing say in a search box (like in market, maps, etc.) and you see a choice that is almost what you want, you cannot select it and modify it.For example, I accidentally type pinboll in market.It finds nothing.I start to type pin again, there is pinboll. There seems to be no way to select that and be able to change the one letter. I have to retype the whole thing. Am I missing something?
View 3 Replies View RelatedI have a working ListActivity class. Each of the list item consists of an ImageView and a TextView. However, when I try to replace the ImageView with ImageButton, The list becomes unselectable. The onListItemClick or any other function no longer get called when press a list item (Although the track ball can still focus a list item, but nothing more can be done). I have searched the forum and also the internet and failed to find any such working example, apart from one guy reporting a similar problem but with no answer.Code...

View 2 Replies View RelatedI'm creating an currency exchange rate application to learn Android. The app will list all exchange rate in a list, each of them has the layout like this (in essential) code...
To list exchange rate for all currencies I have the following approach:
- Design the layout for one currency (let's choose EUR as first currency)
- Generate the layout for all other currencies automatically by:
1. Copy all properties of the EUR-layout into the new currency layout
2. Modify some properties of new currency layout like: ID, Rates ...
3. Repeat steps 1,2 for all sub-layout of the new currency layout
But I don't know how to code step 1, so I did a lot of google about: "android copy view" "android copy properties" "android copy view" "android clone view" "java clone object" .... but still no solution.
So, my question is: how to copy all properties of a view ?

View 1 Replies View RelatedI am wondering if anyone else is encountering this issue (or if its just me). I converted an app I have been working on from using a regular view to using SurfaceView. The app accesses listviews to change properties of the elements I am drawing on a canvas. The listviews called from the SurfaceView version draw over themselves mis-registered when I scroll long lists quickly. If anyone out there has had a similar problem and/or has an idea what might be going on and/or has a suggestion as to how to fix this.

Where is the right place to specify general user-defined properties, like a host address or a service mail address ? The properties should be accessible from my activities.
I would like to specify such attributes within the AndroidManifest.xml, but there seems to be no elements available for user-defined properties. So the only way may be to put such properties into a resource file as strings or to hide them into the source code...

I would like to create a widget that can reads its attributes from an XML file onCreate. I've created a Custom Button that extends Button widget. I would like to define its layout and styling in an XML, such that the widget can be reused across different views, with the same styling attributes. The notepad sample code does carry some pointers to this problem, however, it defines a XML layout with the component as View, inside LinearLayout, which is not really what I'm trying to achieve here.
