What is the difference between TextView's style and android:textAppearance attributes? -

if define textview as:

 <textview         style="@android:style/textappearance.devicedefault.large"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="hello world!" /> 

it same doing:

 <textview         android:textappearance="@android:style/textappearance.devicedefault.large"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:text="hello world!" /> 

i know style kind of broader qualifier (i.e. 1 can't set attributes in android:textappearance) raises question: why bother? there advantage of using android:textappearance on style?

you can have 1 style attribute per view, using textappearance allows in essence define style using restricted set of text-relevant attributes. can use both style , textappearance in 1 view.
