代码：

PreviewConfig config = new PreviewConfig.Builder().setLensFacing(CameraX.LensFacing.FRONT).build();

    Preview preview = new Preview(config);

    TextureView textureView = findViewById(R.id.textureView);


    preview.setOnPreviewOutputUpdateListener(new Preview.OnPreviewOutputUpdateListener() {

                     @Override
                     public void onUpdated(Preview.PreviewOutput output) {
                            textureView.setSurfaceTexture(output.getSurfaceTexture());
                        }
                    });

                    ImageCaptureConfig imageCaptureConfig = new ImageCaptureConfig.Builder().build();

                    imageCapture = new ImageCapture(imageCaptureConfig);
                    CameraX.bindToLifecycle((LifecycleOwner) this,imageCapture, preview);

添加setLensFacing(CameraX.LensFacing.FRONT)到ImageCaptureConfig应该可以解决您的问题

作为对 Nestos 答案的补充，我必须同时添加 ImageCaptureConfigsetLensFacing(CameraX.LensFacing.FRONT)和 PreviewConfig 才能完成这项工作。

您应该调用您传递给 setLensFacing(..)的每个配置UseCaseCameraX.bindToLifecycle((LifecycleOwner) this, imageCapture, preview)

PreviewConfig ImageCaptureConfig ImageAnalysisConfig 都需要添加

setLensFacing(CameraX.LensFacing.FRONT)

这就是我设置它的方式

您需要将 lensFacing 添加setLensFacing(lensFacing)到以下区域： 1. PreviewConfig 2. ImageCaptureConfig 3. ImageAnalysisConfig

那应该这样做。
