i've been playing android animation framework , found following 3d rotation sample code:

http://developer.android.com/resources/samples/apidemos/src/com/example/android/apis/animation/transition3d.html

http://developer.android.com/resources/samples/apidemos/src/com/example/android/apis/animation/rotate3danimation.html

it pretty want want imageview rotate while it's being translated point point b , should rotate along it's own center(which moving) instead of center of container of screen.

does know how that?

well it's pretty close posted. you're multiplying rotational matrix translation matrix. that's happens under covers. android hides detail it's api:

matrix matrix = transformation.getmatrix(); matrix.rotate( rotatex, rotatey ); matrix.posttranslate( transx, transy );

rotate first translate rotate image around it's own axis first before translating it.
