– R.java is neat & elegant; Every application has resources & common example of resources are strings, colors, drawable and bitmaps. Instead of hard-coding strings in the application, one will use an id for a string.

How do you use strings in R.java file:

One might be preferred to put a constant like “R.id.text” in R.java. But R.java is not editable, even if it were it gets regenerated all the time.

<resources>
<item type=”id” name=”text”/>
</resources>

The “type” refers to the type of resource, in this case, an “id”. here is a perfect example of using R.java elements in code:

<TextView android:id=”@id/text”>
..
</TextView>
