Android – loads an array of integers from XML
•
Android
I have an array of integers in the XML file, as shown below
<integer-array name="myArray">
<item>@drawable/pic1</item>
<item>@drawable/pic2</item>
<item>@drawable/pic3</item>
<item>@drawable/pic4</item>
</integer-array>
In the code, I'm trying to load this array
int[] picArray = getResources().getIntArray(R.array.myArray);
The expected result is
R.drawable.pic1, R.drawable.pic2,R.drawable.pic3
Instead, it takes an array with all values zero
Who can tell me what the problem is?
resolvent:
You need to get an array containing image ID. maybe this article will help you. So you may need code:
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);
}
}
