I'm building a newspaper add (kinda) with two lists views: one list view contains 4 articles from 2020 and the other one has 4 articles from 2021. When the user clicks on an article title, webview opens up the article.
However, I've only previously used one list view and one onItemClick method. I'm really not sure how to get onItemClick to access two different list views when both lists have items in position 0,1,2,3.
With the current code I have each time a user clicks for example on the first link, it will open the article of 2021 of case 0 and then the article of 2020 of case 0.
This is the XML code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView

android:gravity="center"
android:text="The Vanguard"
android:textColor="#FFFFFF"
android:textSize="35sp"
android:textStyle="bold"
android:layout_marginBottom="30dp"/>
<TextView

the WebView code is working. Thanks in advance! :(
Even after this case
case R.id.list_vanguard_2021
you need a break;
