Question

我有两个扫描事件。第一个，我的MainActivity中的QR码扫描代码：

  FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.scanbutton);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent("com.google.zxing.client.android.SCAN");
                intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
                startActivityForResult(intent,10);
            }
        });

而secen one，我AddDataFragment中的简单条形码扫描代码：

        ImageButton ib = (ImageButton) view.findViewById(R.id.button_scan_serial);
        ib.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent("com.google.zxing.client.android.SCAN");
                intent.putExtra("SCAN_FORMATS", "CODE_39,CODE_93,CODE_128,DATA_MATRIX,ITF,CODABAR,EAN_13,EAN_8,UPC_A");
                startActivityForResult(intent,11);
            }
        });

这是onActivityResult

中的MainActivity代码

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
        super.onActivityResult(requestCode, resultCode, intent);

            if (resultCode == RESULT_OK) {
                String scanContent = intent.getStringExtra("SCAN_RESULT");
                String scanFormat = intent.getStringExtra("SCAN_RESULT_FORMAT");
                Log.d("INHALT", scanContent);
                Log.d("FORMAT", scanFormat);

                switch (requestCode){
                    case (10):{
                        String[] Split = scanContent.split("\\s");
                        String product = Split[0];
                        String label = Split[1];
                        String serial = Split[2];
                        String mac = Split[3];
                        String daaid = Split[4];
                        String bill = Split[5];

                        mydb.insertData(product, label, serial, mac, daaid, bill);
                        break;
                    }
                    case (11):{
                        Log.d("TEST", "test test test - arrived here");
                    }
                }
            } else if (resultCode == RESULT_CANCELED) {

                Log.d("TEST", "result_canceled");
                break;
            }

        Fragment fragment;
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        fragment = new ListViewFragment();
        ft.replace(R.id.container, fragment);
        ft.commitAllowingStateLoss();
    }

但如果我扫描条形码，则案例开关没有检测到10。扫描zxing关闭后，弹出ListViewFragment。有什么错吗？如何将scanContent字符串推送到AddDataFragment？

你错过了休息;

switch (requestCode){
        case (10):{
            String[] Split = scanContent.split("\\s");
            String product = Split[0];
            String label = Split[1];
            String serial = Split[2];
            String mac = Split[3];
            String daaid = Split[4];
            String bill = Split[5];

            mydb.insertData(product, label, serial, mac, daaid, bill);
            break;
        }
        case (11):{
            Log.d("TEST", "ICH HABE ERKANNT DAS ICH EINEN BARCODE GESCANNT HABE");
            break;
        }
    }

一个onActivityResult中的两个扫描事件
