Zxing Scanner无法重新初始化

Question

我尝试实现Zxing条形码扫描器库，这是我第一次对其进行完美扫描，并且捕获了条形码。尝试扫描另一个条形码时，以前捕获的条形码图像保持不变。

还可以在扫描仪本身中设置关闭按钮，或者只共享最佳的扫描仪库

代码如下：

        package com.erplogic.handledscanner;

        import me.dm7.barcodescanner.zxing.ZXingScannerView;
        import static android.Manifest.permission.CAMERA;

        public class ScannedDetails extends AppCompatActivity implements 
        AsynchronousResponse , ZXingScannerView.ResultHandler{
        String lineItemID;

        private ZXingScannerView scannerView;
        private LinearLayout  scanner;

        @Override
        protected void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_scanned_details);
            scanner= findViewById(R.id.scan_recycle);
            // Scanner button
            ImageButton scannerButton = findViewById(R.id.scanner_button);
            scannerButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
            recyclerView.setVisibility(View.GONE);
            scannerView = new ZXingScannerView(ScannedDetails.this);
            scanner.addView(scannerView);
            }
         }
         });
        }

        @Override
        public void handleResult(Result result) {
            Toast.makeText(ScannedDetails.this, result.getText(), 
            Toast.LENGTH_LONG).show();
        }

        @Override
        public void onPointerCaptureChanged(boolean hasCapture) {

        }


        @Override
        public void onDestroy() {
            super.onDestroy();

        }

        @Override
        public void onResume() {
            super.onResume();
                    if (scannerView == null) {
                        scannerView = new ZXingScannerView(ScannedDetails.this);
                        scanner.addView(scannerView);
                    }
                    scannerView.setResultHandler(this);
                    scannerView.startCamera(); 
            }
        }
        }
