java - Zxing NotFoundException with Barcode 128C

Question

I try to use Zxing to decode 128C (Code set C) barcodes. I have success when I read other types like QR_CODE, UPC_A.

These are barcodes that I trying to read:

Is possible read 128C barcodes (Not CODE 128 pure) with Zxing ?

Answer 1

简短的回答，是的，应该是可能的。由于 128C 只是 128 的子集。可以扫描代码，可能需要几秒钟。并让 XZing 在应用程序中工作。

你发现支持128，现在你要做翻译。128C 采用与 128 相同的输入，只是输出数字。因此，您可以根据返回的数据进行翻译，并将其转换为 128C。检查第二个链接以了解其翻译方式。

从 XZing github 获取所需的类，将它们放在项目的 java 部分的包中。我只用了2个：

• 意图积分器
• 意图结果

以下是它在我的代码中的启动方式：

/**
* Method called to intiate the scan (it's linked to a button)
*/
public void doScan(View view) {
    IntentIntegrator scanIntegrator = new IntentIntegrator(this);
    scanIntegrator.initiateScan();
}

// when you click the Scan Bar Code button
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    IntentResult scanningResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);

    if (scanningResult != null) { // we have a result


           String scanContent = scanningResult.getContents(); // set the content of the scan.
           String scanFormat = scanningResult.getFormatName(); // set the type of scan.

           // You will want to put this data somewhere else, globals, etc.

        } else {
            toast("No scan data received!"); // call to make a toast
        }
    }
