问题描述

我要扫描QR codeS按钮点击，问题是当我在我的设备操作结果意向变量运行code总是返回0。

I want to Scan QR codes on button Click, problem is when I run code on my device Activity Result Intent variable always returns 0.

我如何知道吧code阅读器的工作？我目前看到的设备屏幕上的黄色小点。

How do I know if the barcode reader work? I currently see yellow dots on the device's screen.

下面是我的code：

private OnClickListener scanner = new OnClickListener() {
    public void onClick(View v) {
        IntentIntegrator.initiateScan(BarCodeScannerActivity.this);
    }
}; 

protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
     IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
     if (scanResult != null) {
           // handle scan result
           String s = "http://www.google.com/search?q=";
           s += scanResult.getContents();

           Intent myIntent1 = new Intent(Intent.ACTION_VIEW, Uri.parse(s));
           startActivity(myIntent1);
     }

感谢

推荐答案

您在code误差

您应该有

@Override
  public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
    if (result != null) {
      String contents = result.getContents();
      if (contents != null) {
        showDialog(R.string.result_succeeded, result.toString());
      } else {
        showDialog(R.string.result_failed, getString(R.string.result_failed_why));
      }
    }
  }

您不能覆盖​​的onActivityResult 如的onCreate 或在onStart

而你正在写的onActivityResult像这是最常见的错误通常的方法。

Rather you are writing onActivityResult like normal method which is most common mistake.

此外，如果你可以提到 integrator.initiateScan（IntentIntegrator.QR_ code_TYPES）; 或 integrator.initiateScan（IntentIntegrator.PRODUCT_ code_TYPES）; 这将是巨大的。

Also if you can mention integrator.initiateScan(IntentIntegrator.QR_CODE_TYPES); or integrator.initiateScan(IntentIntegrator.PRODUCT_CODE_TYPES); it would be great.
