我是开始用zxinglite 但是发现没有多二维码支持 然后用的这个库 这2个库使用非常相似 这个黑屏问题如何解决呢?
麻烦提供相关日志
我先跟踪下是不是我使用问题 我们现在扫码框外的区域要配置黑色 我在想是不是这个颜色导致的

请问多个二维码的时候 result的centeX centerY的坐标是基于谁的呢?

基于分析的图像,显示到屏幕时需要做一次转换,可以参考demo中的示例:QRCodeScanningActivity
如果中间的圆圈是自己传入的图片,也要做缩放动画怎么处理呢? 每次裁剪新的bitmap吗?

已经解决动画问题
/**

Matrix matrix=new Matrix();
matrix.postScale(currentZoomRatio,currentZoomRatio);
matrix.postTranslate(left,top);
canvas.drawBitmap(pointBitmap,matrix,paint);
} else {
paint.setColor(pointStrokeColor);
canvas.drawCircle(point.x, point.y, pointStrokeRadius * currentZoomRatio, paint);
paint.setColor(pointColor);
canvas.drawCircle(point.x, point.y, pointRadius * currentZoomRatio, paint);
}
}

可以用这个ViewfinderView 配置更全面,后续计划会移除MLKit内部的ViewfinderView
但是你这个配置的图片没动画 我不得不去改的源码
