Vertical scanner in portrait screen mode

I’m using custom scanner through DecoratedBarcodeView in my Fragment (like in example of Activity Custom Scanner).

Everything works perfect, but if phone in portrait mode - scanner line and detection are horizontal.

Could you help me please, how can I make it vertical (just for giving scanner mode data to scan), if phone will be only in portrait mode (it’s locked to portrait mode)?

Like this:

Thanks in advance!

There is no built-in way to do this, so you’ll have to dig into the source.

There are two parts to this:

1. The UI. This means changing / overriding ViewfinderView.

2. The decoding. For some barcodes (e.g. QR codes), the orientation doesn’t matter. For others such as 1D barcodes, the TRY_HARDER hint may cause it to scan in both directions. Alternatively, you can rotate the image before decoding (may require changing the library source). You can do this by creating a custom Decoder and DecoderFactory.
