Question

我使用zxing读取QR码。当我在手机处于纵向模式时扫描代码时它工作正常，但是当我在横向模式下扫描它似乎返回时，但onActivityResult方法从未被调用（我的断点甚至没有被击中）

来自构建文件：

compile 'com.journeyapps:zxing-android-embedded:3.0.2@aar'
compile 'com.google.zxing:core:3.2.0'

活动代码。这被调用，但此时fragment为空：

@Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent intent) {
    super.onActivityResult(requestCode, resultCode, intent);
    if (fragment != null && Activity.RESULT_OK == resultCode) {
        fragment.onActivityResult(requestCode, resultCode, intent);
    }
}

以下是片段中的代码：

@Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent data) {

    // Handle QR scan result
    if (Activity.RESULT_OK == resultCode) {
        final IntentResult scanResult = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if (scanResult != null) {
            final String contentString = scanResult.getContents();
            if (Strings.isNotEmpty(contentString)) {
                processDataAsynchronously(contentString);
            }
        }
    }
}

OnClick代码：

@Override
public void onClick(final View v) {

    int viewId = v.getId();

    if (viewId == R.id.check_qr_button) {

        // Get permissions to use the camera
        if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {

            if (ActivityCompat.shouldShowRequestPermissionRationale(getActivity(), Manifest.permission.CAMERA)) {

                final Runnable cameraPermissionsRunnable = new Runnable() {
                    @Override
                    public void run() {
                        ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION);
                    }
                };

                // Why we request this permission
                DialogManager.showOkDialog(getActivity(), R.string.permissions_explanation_camera_qr, true, cameraPermissionsRunnable, true, true);

            } else {

                ActivityCompat.requestPermissions(getActivity(), new String[]{Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION);

            }
        } else {


            IntentIntegrator.forSupportFragment(this).initiateScan();

            //ALSO TRIED THIS BUT DIDN'T WORK EITHER
             /*
            final IntentIntegrator integrator = new IntentIntegrator(getActivity());
            integrator.setOrientationLocked(false);
            integrator.setBeepEnabled(true);
            integrator.initiateScan();
            */

        }
        return;
    }

    super.onClick(v);
}

感谢您的任何提示！

在Android中处于横向模式时，zxing不返回扫描的QR码
