What is difference among styles.xml and themes.xml

May I know what is the difference between

? To me, they just look same as both XML are in the same format.

<style name="...
<item name="...

So, in my app which provide customization coloring, size, drawable, ... do I need both
as well? How should I decide which XML to put in which file?

Out of the whole page of the Styles and Themes. You may be looking for this line.

When you apply a style to a single View in the layout, the properties defined by the style are applied only to that View. If a style is applied to a ViewGroup, the child View elements will not inherit the style properties—only the element to which you directly apply the style will apply its properties. However, you can apply a style so that it applies to all View elements—by applying the style as a theme.

When you apply as theme, it changes everything in scope, depending if you applied it on Activity or Application. Style is more 'local'.
