    button = (Button) view.findViewById(R.id.zing);

    button.setOnClickListener(new View.OnClickListener() {

            Intent intent = new Intent("com.journeyapps.barcodescanner.CaptureActivity");

试试这个，为我工作

在主要活动中添加此代码

  @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        try {
                for (Fragment fragment : getSupportFragmentManager().getFragments()) {
                fragment.onActivityResult(requestCode, resultCode, data);
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

Zxing库不显示片段活动中的扫描结果
