animated toggle button

问题

I have created animated toggle and it works perfect if android:checked="true" ie: it plays drawable from 1-9 but if android:checked="false" its stuck at drawable 10 but it should play from 10-20 .It works perfect from then on but when the app starts it has the above problem .

Why is it stuck at drawable 10 when in reality it should be at 20 as that is the final image.(Off) currently as its stuck at 10 it looks like its still ON .

you must rename you file from "animatedbutton_OFF.xml" on "animatedbutton_off.xml" And from "animated_button_on.xml" on "animatedbutton_on.xml"
