android - Zxing 导致应用程序停止并退出

Question

我正在尝试将 zxing 作为库添加到我的 Android 应用程序中 - 它必须处于离线状态，因此使用 Intent 到外部应用程序是不好的，因为很多人没有条形码扫描仪。 我有 Zxing 作为库，名称是“zxingLib”，并在我的应用程序中添加了“IntentIntegrator”和“IntentResult”+ core.jar。

在我的应用程序中，我通过按钮调用 zxing:

public void scanNow(View view){

    IntentIntegrator integrator = new IntentIntegrator(this);
    integrator.initiateScan();
}

并获得结果:

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
      IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
      if (scanResult != null) {
          intent.putExtra("com.tajchert.kolejrogowska.SCAN.SCAN_MODE", "QR_CODE_MODE");
          String contents = intent.getStringExtra("SCAN_RESULT");
          String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
          Toast toast = Toast.makeText(this, "Content:" + contents + " Format:" + format , Toast.LENGTH_LONG);
          toast.setGravity(Gravity.TOP, 25, 400);
          toast.show();
      }
    }

按下后显示安装条形码阅读器的消息(来自谷歌播放)-我做错了什么？ 但如果我的手机上已经有条形码，它就会停止(应用程序和条形码阅读器)。 日志猫:

知道这个错误的原因是什么吗？在一个示例中，我看到我的 Activity 应该扩展 ActivityCapture 而不是 Activity，但如果我这样做，Eclipse 会将其标记为错误。

Answer 1

I'm trying to add zxing as library to my android app

ZXing 团队不支持此功能，我上次检查过。

it must be offline so using Intent to outside app is bad as many people wouldn't have bar code scanner

据推测，他们在安装您的应用程序时处于在线状态。因此，想必他们在安装条码扫描仪后就可以上网了。

and in my app "IntentIntegrator" and "IntentResult" + core.jar added.

IntentIntegrator 用于与条形码扫描仪应用程序集成。您说过您不想与条形码扫描仪应用程序集成。

After pressing it show messege to install Barcode reader (form google play) - what I'm doing wrong?

您正在使用 IntentIntegrator，它正在尝试与条形码扫描仪应用集成。

Any idea what is couse of that error?

这似乎是条形码扫描仪应用程序中的问题。尝试从启动器运行条形码扫描仪，看看它是否也崩溃。如果是这样，则条码扫描仪和您的设备之间存在一些不兼容。
