including layout in another layout

Question

I want to include a layout in another layout in one of my application.But i am not able to do it with the help of tag.It is showing the error message that You must specifiy a layout in the include tag: .Here are the both xml files:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

      <include 
        android:id="@layout/linearlayout"


        />  
</LinearLayout>

This is the 2nd one:

<?xml version="1.0" encoding="utf-8"?>

            android:text="@string/home_bycountry" 
            android:drawableTop="@drawable/ic_home_bycountry" />
    <!--    <Button 
            android:id="@+id/naseeb"
            android:drawable="@drawable/ic_launcher"
            />  -->

    </naseeb.bar.DashboardLayout>
    </LinearLayout>
    <!--     <Button
        android:id="@+id/drinking_status"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textSize="10dp"

        android:padding="10dip"
        android:background="@color/Orange" 
        android:gravity="center"
        android:visibility="gone" /> -->

Please tell me how to solve this problem.

Answer 1

Your include tag should have a layout attribute. The id is used like any other element.

<include android:id="@+id/whatever" layout="@layout/linearlayout" />

Also, like any other tag, the id attribute is not required.
