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. Do we have to use opengl only or we can achieve it with other alternative option. Also, when the text is clicked it opens the related news in a different screen. EDIT I finally found some solution for this, which is available under this package. But, the animation is not smooth

有些话、适合烂在心里 提交于 2019-12-12 03:57:02
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. Then I rotate FrameLayout on some user event using RotateAnimation so imageView2 should become visible and imageView1 should go out of screen. But imageView2 still remains invisible. Does anyone know what's the reason? The code is too large and complicated to show here. But as I have figured out the main problem in translating and

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
