Firebase ML自定义相机预览

Question

有人尝试制作Camera View for Firebase或通常具有自定义视图。不仅从受支持的视图（例如320x240或1920x480），而且例如从300x900或1000x400

我的相机创建代码：

private void createCameraPreview() {
        final int width = componentsOverlayFactory.configHolder.pluginWidth;
        final int height = componentsOverlayFactory.configHolder.pluginHeight;

        if (preview == null) {
            preview = componentsOverlayFactory.initLayout(width, height, this);
            GraphicOverlay graphicOverlay = componentsOverlayFactory.getGraphicOverlay();
            CameraSourceApi1 cameraSource = componentsOverlayFactory.getCameraSource(getActivity(), this);
            try {
                CameraSourceApi1Preview apiPreview = (CameraSourceApi1Preview) preview;
                apiPreview.start(cameraSource, graphicOverlay);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

        if (preview == null) {
            //            case with not inited mode
            return;
        }

        final int x = componentsOverlayFactory.configHolder.offsetX;
        final int y = componentsOverlayFactory.configHolder.offsetY;

        view.setOnTouchListener(componentsOverlayFactory.onTouchListener);
        FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(width, height);
        layoutParams.setMargins(x, y, 0, 0);
        frameContainerLayout = (FrameLayout) view.findViewById(getResources().getIdentifier("frame_container", "id", appResourcesPackage));
        frameContainerLayout.setLayoutParams(layoutParams);
        if (mainLayout == null) {
            mainLayout = (FrameLayout) view.findViewById(getResources().getIdentifier("video_view", "id", appResourcesPackage));
            mainLayout.setLayoutParams(new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT));
            mainLayout.addView(preview);
            mainLayout.setEnabled(false);

            if (componentsOverlayFactory.configHolder.freezeFunction) {
                final Button freezeButton = componentsOverlayFactory.getFreezeButton();
                view.addView(freezeButton, new FrameLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, FrameLayout.LayoutParams.WRAP_CONTENT, Gravity.TOP | Gravity.LEFT));
            }

        }
    }

非常感谢您的帮助
