Loading Integer Array from xml

Question

I have an integer array in an xml file as follows

    @drawable/pic1
    @drawabl         


        

Answer 1

Just make it a normal resource array. You could do it like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
   <array name="icons">
       <item>@drawable/home</item>
       <item>@drawable/settings</item>
       <item>@drawable/logout</item>
   </array>
</resources>

Then don't make a int[] just make a TypedArray like this:

TypedArray icons = getResources().obtainTypedArray(R.array.icons);

and get it with:

imageview.setImageDrawable(mIcons.getDrawable(position));

You need to get an array with id's of your images. Probably this article helps you. And so the code you probably need:

int[] picArray = new int[4];

for (int i = 1; i <=4; i++)
{
  try 
  {
    Class res = R.drawable.class;
    Field field = res.getField("pic"+i);
    picArray[i-1] = field.getInt(null);
  }
  catch (Exception e)
  {
    Log.e("MyTag", "Failure to get drawable id.", e);
  }
}

Answer 3

Found this solution:

TypedArray ar = context.getResources().obtainTypedArray(R.array.myArray);
int len = ar.length();

int[] picArray = new int[len];

for (int i = 0; i < len; i++)
    picArray[i] = ar.getResourceId(i, 0);

ar.recycle();

// Do stuff with resolved reference array, resIds[]...
for (int i = 0; i < len; i++)
    Log.v (TAG, "Res Id " + i + " is " + Integer.toHexString(picArray[i]));

And resources xml file could be:

<resources>
    <integer-array name="myArray">
        <item>@drawable/pic1</item>
        <item>@drawable/pic2</item>
        <item>@drawable/pic3</item>
        <item>@drawable/pic4</item>
    </integer-array>
</resources>

Answer 4

It looks like you might be talking about typed arrays?

if so a typed array should look like this:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <array name="icons">
        <item>@drawable/home</item>
        <item>@drawable/settings</item>
        <item>@drawable/logout</item>
    </array>
    <array name="colors">
        <item>#FFFF0000</item>
        <item>#FF00FF00</item>
        <item>#FF0000FF</item>
    </array>
</resources>

Can you show us your actual xml file so we can help you?

EDIT: Yeah those are not integers. make it a resource array if you want to store resources.
