Android Camera2 可调功能适配 [b]首先获取到设备等级：[/b] Float hardwareLevel = mCameraCharacteristics.get(CameraCharacteristics.INFO_SUPPORTED_HARDWARE_LEVEL); LEGACY < LIMITED < FULL < LEVEL_3. 越靠右边权限越大 •INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY = 2 •INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED = 0 •INFO_SUPPORTED_HARDWARE_LEVEL_FULL = 1 •INFO_SUPPORTED_HARDWARE_LEVEL_3 = 3 在相应的等级下面会有各自支持的功能，LEGACY为最低权限 [b]在LIMITED中 [/b] android.request.availableCapabilities [b]介绍：[/b]List of capabilities that this camera device advertises as fully supporting. int[] ints = mCameraCharacteristics.get(CameraCharacteristics.REQUEST_AVAILABLE_CAPABILITIES); [b]Possible values:[/b] •BACKWARD_COMPATIBLE •MANUAL_SENSOR •MANUAL_POST_PROCESSING •RAW •PRIVATE_REPROCESSING •READ_SENSOR_SETTINGS •BURST_CAPTURE •YUV_REPROCESSING •DEPTH_OUTPUT •CONSTRAINED_HIGH_SPEED_VIDEO [b]这些值对应的特征值举例： [/b] final String name3 = CaptureRequest.SENSOR_FRAME_DURATION.getName(); name3 -》android.sensor.frameDuration 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。 [b]如果有匹配则是可控；[/b] CaptureRequest.LENS_FOCUS_DISTANCE；调节焦距 CaptureRequest.CONTROL_AF_MODE；自动对焦模式 CaptureRequest.SENSOR_SENSITIVITY 调节iso CaptureRequest.CONTROL_AE_MODE 自动曝光模式 以上这篇Android camera2 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编程素材网。
