使用ZXing（Android上的），如果你启动一个PDF417条码code扫描这样的...
Using ZXing (on Android), if you initiate a PDF417 barcode scan like this...
List<String> oDesiredFormats = Arrays.asList("PDF_417".split(","));
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.initiateScan(oDesiredFormats);
...你启动一个的所有codeS（除PDF417，也许其他一些）条code扫描这样的...
... and you initiate an "all codes" (except PDF417 and maybe a few others) barcode scan like this...
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.initiateScan();
...那你怎么启动单杆code扫描，将同时识别（所有的标准codeS和PDF417）？在此先感谢！
... then how do you initiate a single barcode scan that will recognise both (all the standard codes, and PDF417)? Thanks in advance!
推荐答案
如果你不指定它，它会默认为任何用户配置的扫描。这在默认情况下包括大多数格式，但不PDF417。所以，我认为你必须在这里列举的所有格式。这不是太辛苦，但你真的想要吗？通常你拥有最多是在扫描一些相关的格式的使用案例。
If you don't specify it, it will default to scanning for whatever the user has configured. This by default includes most formats but not PDF417. So, I think you'd have to enumerate all the formats here. It's not too hard, but do you really want that? usually you have a use case that is scanning for a few related formats at most.
