java - Everything is perfect but there is something missing

Question

• Everything is perfect but there is something missing!

• Program error-free random works properly

• but I want it to do the random inside the string. How can I do this? Can you give code directly

• these are the current codes I use

Main.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center">

    <TextView
        android:id="@+id/tw1"
        android:textSize="50dp"
        android:text="0"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    
    <Button 
        android:id="@+id/btn1"
        android:text="random"
        android:textSize="50dp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    

</LinearLayout>

Strings.xml

    <string name="app_name">JarTest</string>
    <string-array name="status">
        <item>Available</item>
        <item>Busy</item>
    </string-array>

Mainactivity.Java

Ex

String name[] = {"pls","sld","ohg","oug","tpp","ohf","yyyyyyy6",};

Buton click

Random m = new Random();
                        int index = m.nextInt(name.length - 0) + 0;
                        tw1.setText(name[index]);
