The easiest thing to do is to define the values you want to capture separately from the layout files. Then you can retrieve the values directly. For instance:

some layout file

<Button
    android:paddingLeft="@dimen/left_padding"
    android:checked="@bool/default_checked"
    . . .
    />

some file in res/values

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="left_padding">3dp</dimen>
    <bool name="default_checked">true</bool>
    . . .
</resources>

In view code

Resources res = getResources();
int leftPadding = res.getDimension(R.dimen.left_padding);
boolean defaultChecked = res.getBoolean(R.bool.default_checked);

You can then save leftPadding and defaultChecked in an XML file (but not a resource file!), in shared preferences, etc. But I think it would be easiest to just retrieve the resource value directly each time you need it.
