How do I get an imageview to rotate while translating in Android?
I am trying to make an imageview that rotates while sliding across the screen. I setup a rotate animation for 180 degrees, and it works by itself. I setup a translate animation and it works by itself. When I combine them I get an imageview that makes a big spiral. I would like the imageview to rotate around the center of the imageview while being translated.
AnimationSet animSet = new AnimationSet(true);
//Translate upwards and to the right.
TranslateAnimation anim =
new TranslateAnimation(
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, +80.0f,
Animation.ABSOLUTE, 0.0f, Animation.ABSOLUTE, -100.0f
);
anim.setInterpolator(new DecelerateInterpolator());
anim.setDuration(400);
animSet.addAnimation(anim);
//Rotate around center of Imageview
RotateAnimation ranim = new RotateAnimation(0f, 180f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIV开发者_开发问答E_TO_SELF, 0.5f); //, 200, 200); // canvas.getWidth() / 2, canvas.getHeight() / 2);
ranim.setDuration(400);
ranim.setInterpolator(new DecelerateInterpolator());
animSet.addAnimation(ranim);
imageBottom.startAnimation(animSet);
Well I guess I "rubber ducked" this one.
The order that the animations are applied matters. I switched the order from translate/rotate to rotate/translate and it works.
