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.
-
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"/>
-
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); } }
