Java Zxing条形码扫描仪与android应用程序集成时不扫描条形码

嗨，我已经成功地将Zxing扫描仪集成到我的应用程序中，但我遇到的问题是，它不想扫描条形码，但它可以完美地扫描二维码。当我自己打开Zxing应用程序时，条形码扫描仪工作。只有当我从正在构建的应用程序中启动它时，它才起作用。以前有没有人遇到过这个问题并找到了解决方案

 static final String ACTION_SCAN = "com.google.zxing.client.android.SCAN";


        //product barcode mode

                intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
                startActivityForResult(intent, 0);
            } catch (ActivityNotFoundException anfe) {
                //on catch, show the download dialog
                showDialog(BarcodeScanner.this, "No Scanner Found",  "Download a  scanner code activity?", "Yes", "No").show();
            }
        }

                   //get the extras that are returned from the intent
                    String tagNo = intent.getStringExtra("SCAN_RESULT");
                    String format =    intent.getStringExtra("SCAN_RESULT_FORMAT");
                    MySOAPCallActivity cs = new MySOAPCallActivity();

                    //tagNo = editTagNumber.getText().toString();

                    if(Local.isSet(getApplicationContext(), "EventName"))
                    {
                        eventName = Local.Get(getApplicationContext(), "EventName");

                    }
                    if(eventName.length() > 0) {

                       TagParams params = new TagParams(cs, tagNo, eventName);

                        //Make yes no buttons visible
                        Button buttonYes =     (Button)findViewById(R.id.buttonYes);
                        Button buttonNo = (Button)findViewById(R.id.buttonNo);
                       buttonYes.setVisibility(View.VISIBLE);
                       buttonNo.setVisibility(View.VISIBLE);

                        TextView nameSurname = (TextView)    findViewById(R.id.nameSurname);
                        nameSurname.setText("");
                        TextView idNumber = (TextView) findViewById(R.id.idNumber);
                        idNumber.setText("");
                        TextView ticketClass = (TextView)    findViewById(R.id.ticketClass);
                        ticketClass.setText("");



                        new CallSoapTicketValidForEvent().execute(params);
                    }

                }

                ;
            }
        }

这是渐变

调试代码你发现了什么吗？共享你的代码和build.gradle？@abhijitchara我在调试中没有发现任何东西。@MithunSarkerShuvro iv将代码附在上面调试扫描仪活动？调试代码你发现了什么吗？共享你的代码和build.gradle？@abhijitchara我在调试中没有发现任何东西。@MithunSarkerShuvro iv将代码附在“调试扫描仪活动”储罐上。最后一个很有效。我不得不把它改成“39码”坦克。最后一个很有效。我不得不把它改成“代码39”
