How to Switch between One-off Scan & Continuous Scan

The default scan mode of the helloWorld sample is one-off scan. Here shows the sample code for you to switch the scan mode to continuous scan.

  1. Add a textView in the layout file for displaying the results.

     <TextView
         android:id="@+id/tv_res"
         android:layout_width="match_parent"
         android:layout_height="200dp"
         android:layout_marginTop="430dp"
         android:textSize="16sp"
         android:gravity="center"
         android:scrollbars="vertical"
         android:textColor="@color/white"
         android:visibility="visible"/>
    
  2. Modify the method showResult with the following code:

     private void showResult(TextResult[] results) {
         String strRes = "";
         if (results != null && results.length > 0) {
             DCEFeedback.vibrate(this);
             for (int i = 0; i < results.length; i++)
                 strRes += results[i].barcodeText + "\n\n";
             TextView textView = findViewById(R.id.tv_res);
             textView.setText(strRes);
         }
     }
