如何在Android Vision API中设置全屏显示？

Question

I want to create a barcode scanner that uses full screen. I used google's vision API samples that can be found here

This is my result:

I want to make a preview of the camera to the full height, how can I do it?

Answer 1

In CameraSourcePreview.java find this if condition and change it to:

if (childHeight < layoutHeight) {
childHeight = layoutHeight;
childWidth = (int)(((float) layoutHeight / (float) height) * width);
}

If you want to match parent for width and height you can use

childHeight = layoutHeight; childWidth = layoutWidth;
