zxing QRscanner 的不同结果

Question

我有三个不同的 EditText 和三个不同的 Qr 按钮。每个按钮 setText 到每个 EditText。谁能帮我一下。

扫一扫功能

public void scanQRCode(View view, String from) {
        IntentIntegrator integrator = new IntentIntegrator(this);
        integrator.setDesiredBarcodeFormats(IntentIntegrator.QR_CODE_TYPES);
        integrator.setOrientationLocked(true);
        integrator.setCameraId(0);
        integrator.setBeepEnabled(false);
        integrator.setBarcodeImageEnabled(false);
        integrator.addExtra("from", from);
        integrator.initiateScan();
    }

Activity 结果

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        final IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if (result != null) {
            if (result.getContents() == null) {
                Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
            } else {
                //do any.


            }
        } else {
            // This is important, otherwise the result will not be passed to the fragment
            super.onActivityResult(requestCode, resultCode, data);
        }
    }

我可以放一些类似 intent putextra 的东西来检查我点击了哪个按钮吗？希望有人能帮忙。非常感谢

int clickedButton = 0;

findViewById(R.id.your_button).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            clickedButton = 1;
        }
    });

findViewById(R.id.your_button).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            clickedButton = 2;
        }
    });

findViewById(R.id.your_button).setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            clickedButton = 3;
        }
    });

在 onActivityResult 中检查 if(clickedButton == 1) 将文本设置为特定的编辑文本
