Many articles are old and outdated. After searching for them for a long time, only the two are useful =.

The zing package is 3.1, linked to the following http://pan.baidu.com/s/1pKfkQVp

 

The MainActivity code is as follows:

Xml Code

It is probably the sauce purple

 

 

For garbled questions, google will answer all kinds of questions directly. What I use is

 Hashtable hints = new Hashtable();hints.put(EncodeHintType.CHARACTER_SET, "UTF-8");BitMatrix qrcode = new QRCodeWriter().encode(in, BarcodeFormat.QR_CODE, 400, 400,hints);
