我想自定义条形码的捕获区域，并且我正在使用zxing嵌入式条形码，因此我应该如何自行设置条形码区域的边界.我只知道对ViewFinder类进行了一些更改，但是ViewFinder类在jar库的库中，所以我该如何更改?

I want to customize the capturing area of barcode and i am using the zxing embeded barcode so how shall i make the border of barcode area by my self. I just know that some changes would be don to ViewFinder class but the ViewFinder class is in library in jar library so how could i change it?

我只想制作自定义条形码边框

I just want to make the customize barcode border

推荐答案

只需将#00000000设置为app:zxing_viewfinder_mask的值，然后添加包含该蒙版的ImageView

Just set #00000000 as value of app:zxing_viewfinder_mask, and add an ImageView that contain the mask

app:zxing_viewfinder_mask="#00000000"
