无法从Android中的QR码提取数据

Question

After scan QR code, app will get Event title, start date, end date and location.
( html code: encodeURIComponent(txt1 + "\\n" + txt2 + "\\n" + txt3 + "\\n" + txt4) )

And how to put those value into this code:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
    if(result != null){
        if(result.getContents()==null){
            Toast.makeText(this, "You Cancelled the Scanning", Toast.LENGTH_LONG).show();
        }
        else {
            Calendar cal = Calendar.getInstance();
            Intent intent = new Intent(Intent.ACTION_EDIT);
            intent.setType("vnd.android.cursor.item/event");
            intent.putExtra("beginTime", ?);
            intent.putExtra("allDay", true);
            intent.putExtra("rrule", "FREQ=YEARLY");
            intent.putExtra("endTime", ?);
            intent.putExtra("title", ?);
            intent.putExtra("eventLocation", ?);
            startActivity(intent);
        }
    }
    else{
        super.onActivityResult(requestCode, resultCode, data);
    }
}

You can use String.split() to divide the string into substring. This will give you an array of strings that you can pass to the intent.

        String result = "Event title <br> start date <br> end date <br> location"
        String[] info = result.split("<br>");
        Calendar cal = Calendar.getInstance();
        Intent intent = new Intent(Intent.ACTION_EDIT);
        intent.setType("vnd.android.cursor.item/event");
        intent.putExtra("beginTime", info[1].trim());
        intent.putExtra("allDay", true);
        intent.putExtra("rrule", "FREQ=YEARLY");
        intent.putExtra("endTime", info[2].trim());
        intent.putExtra("title", info[0].trim());
        intent.putExtra("eventLocation", info[3].trim());
        startActivity(intent);
