Hi There! I want to use check box with animated background to switch between checked and unchecked states using only android resources without any java code (I want to have separate resources for older and newer android versions) I found out some guide here <https://developer.android.com/training/material/animations.html> but it does't work as I want. So I should have two transition for each state from state_on to state_off and from state_off to state_on. I've tried to write animated-selector as in guide but it does't animate states switch at all. This is my code of selector: <animated-selector xmlns:android="http://schemas.android.com/apk/res/android";> <!-- provide a different drawable for each state--> <item android:id="@+id/state_on" android:drawable="@drawable/rec_on" android:state_checked="true"/>
<item android:id="@+id/state_off" android:drawable="@drawable/rec_off"/> <transition android:drawable="@drawable/rec_off" android:fromId="@+id/state_off" android:toId="@+id/state_on"> <animation-list> <item android:drawable="@drawable/out_on" android:duration="500"/> </animation-list> </transition> <transition android:drawable="@drawable/rec_on" android:fromId="@+id/state_on" android:toId="@+id/state_off"> <animation-list> <item android:drawable="@drawable/out_off" android:duration="500"/> </animation-list> </transition> </animated-selector> @drawable/out_on code: <?xml version="1.0" encoding="utf-8"?> <animated-vector xmlns:android="http://schemas.android.com/apk/res/android"; android:drawable="@drawable/rec_off"> <target android:name="outer" android:animation="@anim/outer_on"/> <target android:name="inner" android:animation="@anim/inner_on"/> </animated-vector> all animations has almost the same code but it depends of state. @anim/inner_on code: <?xml version="1.0" encoding="utf-8"?> <set> <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android"; android:duration="500" android:propertyName="pathData" android:valueFrom="M 70 992.3622 C 75.5228474983 992.3622 80 996.839352502 80 1002.3622 C 80 1007.8850475 75.5228474983 1012.3622 70 1012.3622 C 64.4771525017 1012.3622 60 1007.8850475 60 1002.3622 C 60 996.839352502 64.4771525017 992.3622 70 992.3622 Z" android:valueTo="M 70 957.3622 C 94.8528137424 957.3622 115 977.509386258 115 1002.3622 C 115 1027.21501374 94.8528137424 1047.3622 70 1047.3622 C 45.1471862576 1047.3622 25 1027.21501374 25 1002.3622 C 25 977.509386258 45.1471862576 957.3622 70 957.3622 Z" android:valueType="pathType"/> </set> And then I tried next solution with single transition but with reversible=true: <animated-selector xmlns:android="http://schemas.android.com/apk/res/android";> <!-- provide a different drawable for each state--> <item android:id="@+id/state_on" android:drawable="@drawable/rec_on" android:state_checked="true"/> <item android:id="@+id/state_off" android:drawable="@drawable/rec_off"/> <!-- specify transitions --> <transition android:fromId="@+id/state_off" android:reversible="true" android:toId="@+id/state_on"> <animated-vector android:drawable="@drawable/rec_off"> <target android:name="outer" android:animation="@animator/outer_on" /> <target android:name="inner" android:animation="@animator/inner_on" /> </animated-vector> </transition> </animated-selector> This selector animates states switch but in a quite strange way: if my checkbox has standard button drawable - it works perfectly, but if I set another drawable for button or @null selector skips transition from state_on to state_of. Also I've tried to move transitions into <item> tag and I've got the same result as with first animated-selector. Moreover I found out that <set> tag is't allowed inside <item> tag as in template.
