android - ImageButton animation not applied to all states -

i have imagebutton image rotates device orientation image/ button horizontal (note rotations handled manually, not through activity life-cycle).

this works great, except when user presses button (state pressed), 90' rotation lost temporarily.

button animation;

<rotate  xmlns:android="http://schemas.android.com/apk/res/android"     android:fromdegrees="0"     android:todegrees="-90"     android:pivotx="50%"     android:pivoty="50%"     android:duration="200" android:fillafter="true"> </rotate> 

the image button drawable;

<selector xmlns:android="http://schemas.android.com/apk/res/android">      <item android:state_pressed="true"           android:drawable="@drawable/btn_go_back_pressed" />      <item android:state_enabled="false"           android:drawable="@drawable/btn_go_back_disabled" />      <item android:drawable="@drawable/btn_go_back_normal" />  </selector> 

loading animation;

animationutils.loadanimation(mcontext, r.anim.button_rotate90); 

and when device orientation changes;

    case messageque.set_to_portrait:         inportrait = true;         (view ib : buttonstoanimate) {             if (ib instanceof textview) {                 ib.startanimation(cntportraitanim);             } else {                 ib.startanimation(btnportraitanim);             }         } 

does have ideas on why, , more importantly, how fix it?

excellent pointer whitney - solved visibility issues having well. above code has been replaced with;

case messageque.set_to_landscape:     (view ib : buttonstoanimate) ib.animate().rotation(0).setduration(200);     break; case messageque.set_to_portrait:     (view ib : buttonstoanimate) ib.animate().rotation(-90).setduration(200);     break; 

thanks.
