Methods Summary
private com.android.layoutlib.api.IStyleResourceValuecreateStyle(java.lang.String styleName, java.lang.String items)
Creates a {@link IStyleResourceValue} based on the given values.

param
styleName the name of the style.
param
items An array of Strings. Even indices contain a style item name, and odd indices a style item value. If the number of string in the array is not even, an exception is thrown.

        StyleResourceValue value = new StyleResourceValue(styleName);
        
        if (items.length % 3 == 0) {
            for (int i = 0 ; i < items.length;) {
                value.addItem(new ResourceValue(items[i++], items[i++], items[i++]));
            }
        } else {
            throw new IllegalArgumentException("Need a multiple of 3 for the number of strings");
