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);

Answer 1

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

Answer 2

作为 nestos 答案的补充，我必须将 setLensFacing(CameraX.LensFacing.FRONT) 添加到 ImageCaptureConfig 和 PreviewConfig 才能使这项工作正常进行。

Answer 3

您应该为您传递给 UseCase 的每个配置调用 setLensFacing(..) CameraX.bindToLifecycle((LifecycleOwner) this, imageCapture, preview)

Answer 4

PreviewConfig ImageCaptureConfig ImageAnalysisConfig 都需要加上

setLensFacing(CameraX.LensFacing.FRONT)

我是这样设置的

Answer 5

您需要将 lensFacing setLensFacing(lensFacing) 添加到以下区域： 1.预览配置 2. ImageCaptureConfig 3.图像分析配置

这样就可以了。
