java - How does the android Xml attribute android:onClick="..." work behind the scenes? -


i'm asking little because im intrested , because im afraid use properties\code don't understand. understand events in java work implementing listener inteface thats appropriate event. happen if implement onclick in activity 2 buttons , third define method android:onclick="..." property? found article, after reading understand probebly implemented using anonymous class implements onclicklistener, i'd sure\know more it, , in way might break something\ use knowledge advantege? android reference isn't clear how works,,,

it uses reflection figure out method call @ runtime. it's view's property, view has relevant code looks if property set, , figure out method name on activity , triggers it.

view bound specific activity's context, , so, able call public method through reflection.

you can see source code of view class here. can see line number 2003, situation being handled.
