问题 Any tricks to get RotateAnimation current angle? I've an imageview that is rotate with RotateAnimation, imageview.getRotation() is always 0.0. Maybe it's a trick to get the rotation angle ? Thaks 回答1: You can use SensorEvent or Position Sensor for get rotation angle. This is help for SensorEvent here. This is help for PositionSensors here. I hope this is help you. 来源： https://stackoverflow.com/questions/26139963/rotateanimation-get-current-angle

问题 I want to create spherical animation in my android app similar to this in News Republic app. I have tried to create a sphere so far but can anyone guide me how to proceed to develop animations like this in android.

问题 I have two ImageView items in FrameLayout : imageView1 and imageView2 . imageView1 is visible and imageView2 is positioned out of screen when activity starts.

Here's the code: public class CarView extends RelativeLayout { private ImageView mBody; private ImageView mLeftWheel; private ImageView

问题 Please read the whole question carefully before marking duplicate or closing it I want to rotate a image(specifically arrow image ) around its center point of base. e.g. At start my image will be like second hand in a clock on 9. And suppose if I rotate that image by 30 degree, it should look like clock second hand on 10 and if 120 degree the clock second hand on 1. So I want to rotate that image around it's center(along x axis) of base. So what should I pass as pivot(X & Y) if I first code
