Values Resources:

Values Resources Provides us a text strings, Integers and color for our application with Optional styling and formatting. In Above Picture, we have one file Named String.xml located in Values Directory.

A string Resources provides text strings for Our application with Optional text styling and formatting, there are three type of resources that can provide our application with strings.

• » String: An XML resource that provides a single string.

<?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">
      <Button
            android:text="@string/Button"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/button1" />
</LinearLayout>

In Above Example, The string for the Button was loaded from the resources by providing the resource ID for the String As shown below.

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string name="app_name">HelloWorld</string>
  <string name="Button">Click ME:</string>
</resources>

• There are two ways to Access a resource:
  1 » Using Code: Using a Static integer from a Sub-class of our resource class, such as:

  Resource.string.Button;
  

  
  

  Where String is the resource type and Button is the resource name.
  
  2 » Using XML: Using a Special XML syntax that also corresponds to the resource ID define in our Resource Class, such as:

  @string/Button
  

  
  

  Where string is the resource type and Button is the resource name.
