Android camera2 判断相机功能是否可控的实例
AndroidCamera2可调功能适配
首先获取到设备等级：
FloathardwareLevel=mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL);
LEGACY •INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY=2 在相应的等级下面会有各自支持的功能，LEGACY为最低权限 在LIMITED中 android.request.availableCapabilities 介绍：Listofcapabilitiesthatthiscameradeviceadvertisesasfullysupporting. int[]ints=mCameraCharacteristics.get(CameraCharacteristics.REQUEST_AVAILABLE_CAPABILITIES); Possiblevalues: •BACKWARD_COMPATIBLE 这些值对应的特征值举例： finalStringname3=CaptureRequest.SENSOR_FRAME_DURATION.getName(); 列出这个的意思是，如果想知道该设备是否支持此功能，可以通过getName()获取其包名，然后在 mCameraCharacteristics.getAvailableCaptureRequestKeys()；生成的队列中寻找。 如果有匹配则是可控； CaptureRequest.LENS_FOCUS_DISTANCE；调节焦距 以上这篇Androidcamera2判断相机功能是否可控的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持毛票票。
