ListActivity (Updated with androidx package)

There is an easy way for listing contents. Also with the help of onListItemClick() method the selected list item can be captured.

-------------------Your Xml code--------------------

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"
    android:background="#64B5F6"
    android:padding="20dp" >

    <TextView
        android:id="@+id/textView1"
        android:layout_marginBottom="5dp"
        android:textStyle="italic|bold"
        android:textSize="25sp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="Android Versions"/>

    <TextView
        android:id="@+id/showVersionTV"
        android:background="#ffffff"
        android:gravity="center"
        android:textSize="25sp"
        android:textStyle="bold"
        android:textColor="#ff0000"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"/>

    <ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="false"/>

</LinearLayout>

------------------------------------------------------

  -----------------------Now the Java code------------------------

package com.apps.yourappname;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;

public class MyListActivity extends ListActivity {

    private TextView showVersionTV;
    private String[] items = {"a","b","c","d","e","f","g","h","i","j","k"};
    private String[] versions = {"alpha","beta","cup cake","donut","eclare","froyo",
            "ginger bread","honey comb","ice cream","jelly bean","kitkat"};

    @Override
    public void onCreate(Bundle b) {

        super.onCreate(b);
        setContentView(R.layout.my_list_activity);
        setListAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1,items));
        showVersionTV = findViewById(R.id.showVersionTV);
    }

    public void onListItemClick(ListView parent, View v, int position, long id) {
        showVersionTV.setText(versions[position]);
    }
}

----------------------------------------------------------------------------------

----------------------------------------Changes in the Manifest file------------------------------------------

Just add the ActivityName in the Manifest file.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.apps.yourappname">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MyListActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>
