Accessing integer resources in xml

Question

I have read this where found that how to access integer resources in java class but no docs for another resource.

Here is Resources at res/values/integers.xml

Answer 1

The accepted answer is completely mis-guiding. Unless there is a specific unique reason, you should never use an Integer resource for setting padding sizes. Not only in XML but also in code. This is why you experienced an UnsupportedOperationException. Integer resources are not scaled based on the DPI of screens. Which means you will not get consistently spaced padding for all devices. Dimen resources will automatically adjust their value for you. Your java code should look like this:

EditText mUsername = (EditText) this.findViewById(R.id.user_name);
int padding = (int) this.getResources().getDimension(R.dimen.input_field_padding);
mUsername.setPadding(padding, padding, padding, padding);

Which, btw, there's no need to set the padding of the EditText element in code if you already set it in the XML. Unless you wanted to change it to a different value at run time.
