Question

我正在尝试使用Zxing Scanner在我的应用程序中制作QR码扫描仪。但是，我使用片段而不是活动。我应该为mScannerView.setResultHandler（??????）添加什么参数。

我的按钮转到QR码扫描仪

FloatingActionButton add = (FloatingActionButton) view.findViewById(R.id.add_friend);
    add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {                
            mScannerView = new ZXingScannerView(getActivity());
            getActivity().setContentView(mScannerView);
            mScannerView.setResultHandler(??????);
            mScannerView.startCamera();
        }
    });

当我使用getActivity（）和getContext（）时出错。请帮助我......谢谢。

Answer 1

mScannerView.setResultHandler(new ZXingScannerView.ResultHandler() {
            @Override
            public void handleResult(Result rawResult) {
                Toast.makeText(getActivity(), "Contents = " + rawResult.getText() + ", Format = " + rawResult.getBarcodeFormat().toString(), Toast.LENGTH_SHORT).show();
            }
});

或者只是实现它

public class ScannerFragment extends BaseFragment implements ZXingScannerView.ResultHandler {

    @Override
    public void handleResult(Result rawResult) {
        Toast.makeText(getActivity(), "Contents = " + rawResult.getText() + ", Format = " + rawResult.getBarcodeFormat().toString(), Toast.LENGTH_SHORT).show();
    }

}
