Specifying drawable resource id in a separate xml

I have an xml file that specifies a set of image button names. Also, I would like to specify the image resource id as an attribute of an xml node as shown below:

<button name="close" resLocation="R.drawable.close" />

I am parsing the xml in the code, I would like to set the image background for the dynamically created button using the resLocation attribute. Since resLocation is a string, I cannot convert to a Drawable object directly. Is there a way I can workaround?

You can try 

<button name="close" resLocation="@drawable/close" />

or try 

ImageButton imgButton=new ImageButton(this);

imgButton.setImageResource(getResources().getDrawable(R.drawable.close));

You can use get getResources().getIdentifier:

String myResourceId = "close"; // Parsed from XML in your case
getResources().getIdentifier(myResourceId, "drawable", "com.my.package.name");

This would require your XML to be a little different:

<button name="close" resLocation="close" />

If you need to keep the R.type.id format in your XML, then you would just need to parse out the type and id:

String myResourceId = "R.drawable.close";
String[] resourceParts = myResourceId.split("\\.");
getResources().getIdentifier(resourceParts[2], resourceParts[1], "com.my.package.name");
