您必须获得运行时权限，然后才能访问您的相机

像

在舱单中

<uses-permission android:name="android.permission.CAMERA" />

private static final int MY_CAMERA_REQUEST_CODE = 100;

     private void processPickImage() {
                if(hasCameraPermission()) {
                    pickImage();
                }
                else
                {
                    requestCameraPermission();
                }            
        }

        private boolean hasCameraPermission() {
            return ContextCompat.checkSelfPermission(context,
                    Manifest.permission.CAMERA) == PackageManager.PERMISSION_GRANTED;
        }

        @TargetApi(Build.VERSION_CODES.M)
        private void requestCameraPermission() {
            requestPermissions(new String[]{Manifest.permission.CAMERA},
                    MY_CAMERA_REQUEST_CODE );
        }

        @Override
        public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                               @NonNull int[] grantResults) {
            switch (requestCode) {
                case MY_CAMERA_REQUEST_CODE :

                    processPickImage();
                    break;
                default:
                    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
            }
        }
