zxing掃描二維碼後，相機卡住了

Question

我用結果處理程序實現了QR碼掃描器。它掃描得很好。但是，第一次掃描完成後，相機會卡住。如何實現QR碼掃描碼，以便相機繼續掃描而不會卡住？

我的代碼如下所示：

public class SimpleScannerFragment extends Fragment implements ZXingScannerView.ResultHandler { 


private ZXingScannerView mScannerView; 
@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
    View v = inflater.inflate(R.layout.scannerview, null); 
    mScannerView = (ZXingScannerView) v.findViewById(R.id.scanner_view); 
    return v; 
} 

@Override 
public void onResume() { 

    super.onResume(); 
    mScannerView.startCamera(); 
    mScannerView.setResultHandler(this); 

} 


@Override 
public void handleResult(Result rawResult) { 
    ParsedResult parserdResult = ResultParser.parseResult(rawResult); 


    Toast.makeText(getActivity(), "Contents = " + rawResult.getText() + ", Format = " + rawResult.getBarcodeFormat().toString(), Toast.LENGTH_SHORT).show(); 
    } 

@Override 
public void onPause() { 
    super.onPause(); 
    mScannerView.stopCamera(); 

    } 
}

根據手冊（https://github.com/dm77/barcodescanner）剛剛恢復您cammera在處理程序：

@Override 
    public void handleResult(Result rawResult) { 
    ParsedResult parserdResult = ResultParser.parseResult(rawResult); 
    Toast.makeText(getActivity(), "Contents = " + rawResult.getText() + ", Format = " + rawResult.getBarcodeFormat().toString(), Toast.LENGTH_SHORT).show(); 
    mScannerView.resumeCameraPreview(this); 
}
