Zxing not working with Tabs

[flynnben123]

I just have a basic continious scan activity but when i tried to implement a tabbed view with the app, the zxing barcodeview no longer worked and it just is a black box with the text on the bottom. PLEASE HELP with this problem....???

[rkistner]

Are the resume() and pause() calls made when the BarcodeView is displayed / hidden?

Are there any errors showing up in the logs?

A small sample app demonstrating the issue would help.

[flynnben123]

There are no errors that come up in the logs, and yes both the resume() and pause() methods are called, here is the scan activity code:

public class ScanActivity extends AppCompatActivity {

private static final String TAG = ScanActivity.class.getSimpleName();
private DecoratedBarcodeView barcodeView;

private BarcodeCallback callback = new BarcodeCallback() {
    @Override
    public void barcodeResult(BarcodeResult result) {
        if (result.getText() != null) {
            barcodeView.setStatusText(result.getText());
        }

    }

    @Override
    public void possibleResultPoints(List<ResultPoint> resultPoints) {
    }
};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_scan);

    barcodeView = (DecoratedBarcodeView) findViewById(R.id.zxing_barcode_scanner);
    barcodeView.decodeContinuous(callback);
}

@Override
protected void onResume() {
    super.onResume();

    barcodeView.resume();
}

@Override
protected void onPause() {
    super.onPause();

    barcodeView.pause();
}

public void pause(View view) {
    barcodeView.pause();
}

public void resume(View view) {
    barcodeView.resume();
}

public void triggerScan(View view) {
    barcodeView.decodeSingle(callback);
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    return barcodeView.onKeyDown(keyCode, event) || super.onKeyDown(keyCode, event);
}}

Added an example with tabs here: https://github.com/journeyapps/zxing-android-embedded/blob/master/sample/src/main/java/example/zxing/TabbedScanning.java

tabbed scanning option doesn't seem to be working.. is there anything else that needs to be done here ?

[rkistner]

@n-mam What specific issue do you get?

Note that the "Tabs" example doesn't do actual scanning - it just demonstrates the camera handling.

[n-mam]

oh okay.. just like all other options, I was expecting the scan to be operational.

Thanks for the clarification

@rkistner Sorry to bother you, but how can I enable actual scanning in the tabbed example?

[sravanthiRaju]

Hi @rkistner .I am also trying scan using tabbed example but it is not working.
Please explain how to enable scanning in fragment in particuler tab.

Thanking You.

[Nonononoki]

@sravanthiRaju I got it working.

Add this to the ScanFragment:

CaptureManager capture;

And add this code in your onCreateView()

capture = new CaptureManager(getActivity(), barcodeView);
capture.initializeFromIntent(getActivity().getIntent(), savedInstanceState);
capture.decode();

[sravanthiRaju]

@Nonononoki Thank you for your answer.
But how we can get the QR code content result.

Thanking You.

@sravanthiRaju

Add this in your Main Activity:

new IntentIntegrator(this).setCaptureActivity(TabbedScanning.class).initiateScan();

[sravanthiRaju]

@Nonononoki Thank You,
But i want display this result value in ScanFragment above scanning screen.I do not want to go back to Main activity.

Please Help me.

[sravanthiRaju]

@Nonononoki Thank you for your replay. And solved my issue.

[natsirasrafi]

@sravanthiRaju

Add this in your Main Activity:

new IntentIntegrator(this).setCaptureActivity(TabbedScanning.class).initiateScan();
