In android studio 1.4.1, I have created new Navigation Drawer Project which is default.My issue is in this project there is nav_header_main.xml file which is for navigation header image and name. I want this image and name should be set programmatically in my main class activity. How to do this, I tried lot but the app crashes.
nav_header_main.xml

As mentioned in the bug 190226, Since version 23.1.0 getting header layout view with:
navigationView.findViewById(R.id.navigation_header_text) no longer works.
A workaround is to inflate the headerview programatically and find view by ID from the inflated header view.
For example:
View headerView = navigationView.inflateHeaderView(R.layout.navigation_header);
headerView.findViewById(R.id.navigation_header_text);
Ideally there should be a method getHeaderView() but it has already been proposed, let's see and wait for it to be released in the feature release of design support library.
don't add header in xml add using code by inflating layout
View hView = navigationView.inflateHeaderView(R.layout.nav_header_main);
ImageView imgvw = (ImageView)hView.findViewById(R.id.imageView);
TextView tv = (TextView)hView.findViewById(R.id.textview);
imgvw .setImageResource();
tv.settext("new text");
In Kotlin
val hView = nav_view.getHeaderView(0)
val textViewName = hView.findViewById(R.id.textViewName) as TextView
val textViewEmail = hView.findViewById(R.id.textViewEmail) as TextView
val imgvw = hView.findViewById(R.id.imageView) as ImageView
imgvw.setImageResource(R.drawable.ic_menu_gallery)
First you need to access the navigation drawer in your MainActivity(or the calling activity) like this:
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
Then you need to remove the header layout from the activity_main.xml because the layout will be inflated programatically in the MainActivity. Your activity_main.xml should look like this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="@menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
Then in your MainActivity, we inflate the nav_header_main layout and get access to its views, in this case the ImageView and TextView
//inflate header layout
View navView = navigationView.inflateHeaderView(R.layout.nav_header_main);
//reference to views
ImageView imgvw = (ImageView)navView.findViewById(R.id.imageView);
TextView tv = (TextView)navView.findViewById(R.id.textview);
//set views
imgvw.setImageResource(R.drawable.your_image);
tv.setText("new text");
navigationView.setNavigationItemSelectedListener(this);

Here is my code below perfectly working Do not add the header in NavigationView tag in activity_main.xml
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="@+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:menu="@menu/activity_main_drawer"
app:itemBackground="@drawable/active_drawer_color" />
add header programmatically with below code
View navHeaderView = navigationView.inflateHeaderView(R.layout.nav_header_main);
headerUserName = (TextView) navHeaderView.findViewById(R.id.nav_header_username);
headerMobileNo = (TextView) navHeaderView.findViewById(R.id.nav_header_mobile);
headerMobileNo.setText("+918861899697");
headerUserName.setText("Anirudh R Huilgol");
nav = ( NavigationView ) findViewById( R.id.navigation );
if( nav != null ){
LinearLayout mParent = ( LinearLayout ) nav.getHeaderView( 0 );
if( mParent != null ){
// Set your values to the image and text view by declaring and setting as you need to here.
SharedPreferences prefs = getSharedPreferences("user_data", MODE_PRIVATE);
String photoUrl = prefs.getString("photo_url", null);
String user_name = prefs.getString("name", "User");
if(photoUrl!=null) {
Log.e("Photo Url: ", photoUrl);
TextView userName = mParent.findViewById(R.id.user_name);
userName.setText(user_name);
ImageView user_imageView = mParent.findViewById(R.id.avatar);
RequestOptions requestOptions = new RequestOptions();
requestOptions.placeholder(R.drawable.ic_user_24dp);
requestOptions.error(R.drawable.ic_user_24dp);
Glide.with(this).load(photoUrl)
.apply(requestOptions).thumbnail(0.5f).into(user_imageView);
}
}
}
Hope this helps.
I know this is an old post but i am sure that this might help someone down the road.
You can simply get the headerView element of the Navigation view by doing this:
NavigationView mView = ( NavigationView ) findViewById( R.id.nav_view );
if( mView != null ){
LinearLayout mParent = ( LinearLayout ) mView.getHeaderView( 0 );
if( mParent != null ){
// Set your values to the image and text view by declaring and setting as you need to here.
}
}
I hope that this helps someone.
It's and old post, but it's new for me. So, it is straight forward! In this part of the code:
public boolean onNavigationItemSelected(MenuItem item) {
} , I bound an ImageView to the LinearLayout, which contains the ImageView from the example, listed below. Mind: it's the same code you get when you start a new project, and choose the template "Navigation Drawer Activity":
<ImageView
android:id="@+id/imageView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingTop="@dimen/nav_header_vertical_spacing"
android:src="@android:drawable/sym_def_app_icon" />
I gave the LinearLayout and ID, inside nav_header_main.xml (in my case I chose 'navigation_header_container' , so it went this way:
LinearLayout lV = (LinearLayout) findViewById(R.id.navigation_header_container);
ivCloseDrawer = (ImageView) lV.findViewById(R.id.imageView);
ivCloseDrawer.setOnClickListener(new View.OnClickListener()
{
@Override
public void onClick(View v)
{
drawer.closeDrawer(GravityCompat.START);
}
});
Note: I have a private ImageView ivCloseDrawer declared at the top, before onCreate (MainActivity).
It worked fine! Hope it helps, Best Regards.
FirebaseAuth firebaseauth = FirebaseAuth.getInstance();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); //displays text of header of nav drawer.
View headerview = navigationView.getHeaderView(0);
TextView tt1 = (TextView) headerview.findViewById(R.id.textview_username);
tt1.setText(firebaseauth.getCurrentUser().getDisplayName());//username of logged in user.
TextView tt = (TextView) headerview.findViewById(R.id.textView_emailid);
tt.setText(firebaseauth.getCurrentUser().getEmail()); //email id of logged in user.
final ImageView img1 = (ImageView) headerview.findViewById(R.id.imageView_userimage);
Glide.with(getApplicationContext())
.load(firebaseauth.getCurrentUser().getPhotoUrl()).asBitmap().atMost().error(R.drawable.ic_selfie_point_icon) //asbitmap after load always.
.into(new SimpleTarget<Bitmap>() {
@Override
public void onResourceReady(Bitmap resource, GlideAnimation<? super Bitmap> glideAnimation) {
img1.setImageBitmap(resource);
}
});
I have made this code by myself with some logic...Its 100% working.....pls do upvote my ans.
The textview and imageview are from @layout/nav_header_main.xml
EDIT : Works with design library upto 23.0.1 but doesn't work on 23.1.0
In main layout xml you will have NavigationView defined, in that use app:headerLayout to set the header view.
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/nav_drawer_header"
app:menu="@menu/navigation_drawer_menu" />
And the @layout/nav_drawer_header will be the place holder of the image and texts.
nav_drawer_header.xml
<?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="170dp"
android:orientation="vertical">
<RelativeLayout
android:id="@+id/headerRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:src="@drawable/background" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="@dimen/action_bar_size"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:background="#40000000"
android:gravity="center"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingLeft="16dp"
android:paddingRight="10dp"
android:paddingTop="5dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="35dp"
android:orientation="vertical"
android:weightSum="2">
<TextView
android:id="@+id/navHeaderTitle"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="@android:color/white" />
<TextView
android:id="@+id/navHeaderSubTitle"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="@android:color/white" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
</LinearLayout>
And in your main class, you can take handle of Imageview and TextView as like normal other views.
TextView navHeaderTitle = (TextView) findViewById(R.id.navHeaderTitle);
navHeaderTitle.setText("Application Name");
TextView navHeaderSubTitle = (TextView) findViewById(R.id.navHeaderSubTitle);
navHeaderSubTitle.setText("Application Caption");
Hope this helps.
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.addHeaderView(yourview);
Also you can use Kotlinx features
val hView = nav_view.getHeaderView(0)
hView.textViewName.text = "lorem ipsum"
hView.imageView.setImageResource(R.drawable.ic_menu_gallery)
