Using NavigationView from Android Design Support Library -


i'm trying follow this tutorial use new drawerlayout design support library.

it seems android studio isn't recognizing navigationview layout.

this main_activity layout:

<android.support.v4.widget.drawerlayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:fitssystemwindows="true">     <linearlayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:padding="20dp">        <textview            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:text="hello"/>    </linearlayout>  <android.support.design.widget.navigationview     android:layout_width="wrap_content"     android:layout_height="match_parent"     android:layout_gravity="start"     app:headerlayout="@layout/drawer_header"     app:menu="@menu/drawer_menu"/> </android.support.v4.widget.drawerlayout>

and when i'm trying run project, i'm getting next error:

error: (19) no resource identifier found attribute 'headerlayout'

but have drawer_header xml file

my bad!

you should, of course, import android support design lib project.

so 'dependencies' area in gradle (app) should that:

dependencies {     compile filetree(dir: 'libs', include: ['*.jar'])     compile 'com.android.support:appcompat-v7:22.2.0'     compile 'com.android.support:design:22.2.0' }
