安卓在录制视频时禁用Camera2自动对焦

CameraManager cameraManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
String cameraId = cameraManager.getCameraIdList()[0]; // 获取相机列表中的第一个相机

cameraManager.openCamera(cameraId, new CameraDevice.StateCallback() {
    @Override
    public void onOpened(@NonNull CameraDevice camera) {
        try {
            // 创建相机捕获会话
            List<Surface> surfaces = new ArrayList<>();
            surfaces.add(surface); // surface为视频录制的目标Surface
            camera.createCaptureSession(surfaces, new CameraCaptureSession.StateCallback() {
                @Override
                public void onConfigured(@NonNull CameraCaptureSession session) {
                    try {
                        // 配置相机参数
                        CaptureRequest.Builder requestBuilder = camera.createCaptureRequest(CameraDevice.TEMPLATE_RECORD);
                        requestBuilder.set(CaptureRequest.CONTROL_AF_MODE, CaptureRequest.CONTROL_AF_MODE_OFF); // 禁用自动对焦

                        // 开始录制视频
                        session.setRepeatingRequest(requestBuilder.build(), null, null);
                    } catch (CameraAccessException e) {
                        e.printStackTrace();
                    }
                }

                @Override

                    // 配置相机会话失败处理
                }
            }, null);
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
