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);
        }
    }
