我正在尝试将 zxing 作为库添加到我的 android 应用程序中 - 它必须处于脱机状态，因此将 Intent 用于外部应用程序是不好的，因为许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();
}
}
按下它后显示消息以安装条形码阅读器（表单谷歌播放） - 我做错了什么？但是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：

知道该错误的原因是什么吗？在一个示例中，我看到我的活动应该扩展 ActivityCapture insted 的 Activity 但如果我这样做，则将其标记为错误。
