I believe rotating outer layout by the amount you want and then the inner layout until it rotates 360 degrees will give you what you want.

float degrees = 30.0f;

outerLayout.setRotation(degrees); innerLayout.setRotation(360 - degrees);

Note that if you need to rotate the views again you should use the full degrees rotat on value. Meaning for 3 rotations 90 degrees, for 4120 etc.

  • thanks Spyros, it works , but rotation is very fast.can we rotate outer layout slow? – B. Rahul Kumar May 08 '19 at 10:47
  • You will need to make an animator and use android:fromDegrees and android:toDegrees. Check this out and try something similar http://www.androidhive.info/2013/06/android-working-with-xml-animations/ – AlephRZS May 08 '19 at 11:02

You can do this with RelativeLayout like this

<RelativeLayout>

   <LinearLayout>  //Your Outer Layout
   </LinearLayout>

   <LinearLayout>  //Your Inner Layout
   </LinearLayout>
</RelativeLayout>

And perform operation on your Outer Layout. You can use any child view inside RelativeLayout according to your need. I just use LinearLayout for example.
