What you learn: You will learn how to specify Arrays in an XML-Resource and how to read them out in your code.

Difficulty: 1 of 5

Description:
Lets take a look at an practical example, which was used in the AndroidFileBrowser 2.0-Tutorial. There we defined the fileEndings for different file-categories(Audio, Text, Images, ...) in an XML-File to make our Application highly generic

You simply have to create an resource of any name (should and with .xml) in your "res/values/"-Directory.
You can define as many Arrays within each file, as you want with as many items you want.

So that was as easy as one can imagine.

Now we surely want to read those "Text"-Arrays into our application as "Real"-Array o fthe Type String. You can do that with the following single line (also from the FileBrowser-Example):


Thats it.

Looks like you can only get 512 items from xml...

Guys, now what if you wanted to change the colors for those array items? How could you proceed to do that?

I've tried several methods but no luck yet. I'm interested in changing the color inside the XML if possible.

Thanks!

Super BIG thanks for that! I've been searching around for this construct and couldn't find it anywhere. All of the examples dwell on creating a spinner from an array of strings in an .xml file. But I want to just pull the items into an array and work with them. Your snippet shows me how to do exactly that!

So, thanks again!

cheers

Is there a solution for this?

Hey guys I know this is really basic, but in the XML layout, how would I display the content of an array that I made in the class file ? Textview is ok with me, but I don't know what command to use.

Hi,

Is it possible to do this but instead of creating the array from an xml file in the Resources folder, it is created from xml data pulled from an external source?

Cheers

Thanks!
Is there any way to get values of parameters in XML?
They are code and icon in my sample:

Good topic,
But how do we can use xml resources like the below one?

<book>
<chapter index="1" name="first one">
<aya index="1" text="second one" />
<aya index="2" text="third one" />
</chapter>
</book>

Thanks in advance

Hi!

I have string array like this


so I can get value of array item by its index in code:



Is there any way to get that value from other resource file?

Hey, I'm actually pretty new to Android dev, but I'm having a problem very similar to this. I was wondering...

Is is possible to create a dynamic array in XML, like say I want to create an array of undefined size, that I want to fill with Absolute Layouts. I want to declare this array in the XML, and define the layout params for the first AbsoluteLayout in XML as well. Then when the program runs I want to be able to add any number of items to this array, all with the same layoutParams as the first AbsoluteLayout I added before. Is this even possible?

The main issue I'm encountering is that when I create an Absolute layout in just Java code, I can't modify the layoutParams because whenever I getLayoutParams() in the absolute layout, it returns null. The only way I can get the LayoutParams is when I define the view in XML first.

I'm trying to create a dynamic menu that I can add absolute layouts to as the program runs. It needs to be an absolute layout so I can directly control the x,y position of all the children views within the layout.

I just don't know how to define this in XML. I know it's a big question, and any tips you could give would be greatly appreciated.

Cheers,
-Marc

Hey, I have the same question as Vadimz. Maybe anyone knows an answer? Would appreciate. Thx!
