Resource Reference name and package

Description

The name part in the resource reference @[package:]type/name is the name given to the resource.

Example

For example, text1 in the following layout file, it also gets represented as an int constant in R.java.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:id="@+id/text1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    />
 <Button
    android:id="@+id/b1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
   />
</LinearLayout>

Note

If you don't specify any package in the syntax @[package:]type/name, the pair type/name is resolved based on local resources and the application's local R.java package.

If you specify android:type/name, the reference is resolved using the package android and specifically through the android.R.java file.

You can use any Java package name in place of the package placeholder to locate the correct R.java file to resolve the reference.
