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]);
