你可以这样做，

IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
        if (result != null) {
            //if qrcode has nothing in it
            if (result.getContents() == null) {
                Toast.makeText(this, " Not Found", Toast.LENGTH_LONG).show();
            } else {
                try {
                    JSONObject obj = new JSONObject(result.getContents());
                 //   Toast.makeText(this,"results"+ result.getContents(), Toast.LENGTH_LONG).show();

                } catch (JSONException e) {
                    e.printStackTrace();
                  //  Toast.makeText(this,"results again : "+ result.getContents(), Toast.LENGTH_LONG).show();
                    staffLoginQRCODE(result.getContents());
                }
            }
        } else {
            super.onActivityResult(requestCode, resultCode, data);
        }
