获取 x 轴上的 Android 旋转角度 [英] Get Android rotation angle in x-axis

问题描述

我正在试验一些 Android 功能.现在，我正在尝试获取设备的旋转角度，因此当我在画布上显示笑脸位图时，它总是看起来直".

I'm experimenting with some Android functions. Right now, I'm trying to get the rotation angle of the device, so when I show a happy face bitmap on a canvas, it always looks "straight".

我所需要的只是获得 x 轴旋转角度(我猜)，但我找不到如何实现它.希望您能够帮助我.谢谢.

All I would need for this, is to get the x-axis rotation angle (I guess) but I can't find how to achieve it. Hope you can help me. Thank you.

推荐答案

您可以使用方位角、俯仰和滚转.不确定哪一个与您的x 轴"有关，但我认为它是方位角.

There is azimuth, pitch and roll available to you. Not sure which one relates to your "x-axis" but I think its azimuth.
