我用结果处理程序实现了QR码扫描仪。扫描得很好。但是，第一次扫描完成后，相机卡住了。如何实现QR扫描代码，以使相机继续扫描而不会卡住？
我的代码如下所示：
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();
}
}
