我可以在手动对焦模式下使用LENS_FOCUS_disTANCE获得焦距值.但是,AF模式下的属性始终为零.在AF模式下有没有办法获得焦距?
解决方法Shortest distance from frontmost surface of the lens that can be
brought into sharp focus.If the lens is fixed-focus,this will be 0.

换句话说,如果您想要管理焦点,请记住LENS_INFO_MINIMUM_FOCUS_disTANCE为您提供最小焦点,但要获得“最大”焦点,您必须使用LENS_INFO_HYPERFOCAL_disTANCE.
float yourMinFocus = mCameracharacteristics.get(Cameracharacteristics.LENS_INFO_MINIMUM_FOCUS_disTANCE);float yourMaxFocus = mCameracharacteristics.get(Cameracharacteristics.LENS_INFO_HYPERFOCAL_disTANCE);总结
