问题
I have a navigation draw with sections and items, but I need to put an image and a text as header but don't know how exactly from what I have, the navigation drawer that I have is the default one that android studio create when you right click and select new > activity > navigation drawer activity.
this is the xml that I want to have as header: nav_header.xml
<?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">
<!-- Character's Avatar -->
<ImageView android:id="@+id/navigation_drawer_header_iv_image"
android:layout_width="200dp"
android:layout_height="200dp"
android:src="@drawable/image_sorcerer"/>
<!-- Character's name -->
<TextView android:id="@+id/navigation_drawer_header_tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Example text"
android:paddingLeft="16dp"/>
</LinearLayout>
The navigation drawer content is set through a custom adapter
GameNavigationFragment class (This is the fragment that manage the navigation drawer)
public class GameNavigationFragment extends Fragment {
private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position";
private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";

}

// Read in the flag indicating whether or not the user has demonstrated awareness of the

mUserLearnedDrawer = sp.getBoolean(PREF_USER_LEARNED_DRAWER, false);

this is how navigation looks like right now:
回答1:
Update your android studio to 1.4 then you can create a navigation drawer activity with header image
回答2:
This is something I'm working into.
activity_main.xml
<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:id="@+id/drawerLayout"
android:fitsSystemWindows="true">
<!-- Contenido Principal -->
<include layout="@layout/main_content"
android:id="@+id/mainContent"/>
<!-- Navigation Drawer -->
<android.support.design.widget.NavigationView
android:id="@+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/nav_menu"/>
</android.support.v4.widget.DrawerLayout>
I am currently using Navigation View pattern. See this property in the NavigationView:
app:headerLayout="@layout/drawer_header"
Where you need yo replace drawer_header with your layout file. If you want to use NavigationView, you have to add this dependency in your Gradle:
compile 'com.android.support:design:22.2.0'
Hope this helps.
