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.

回答2:
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.
回答3:
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");
回答4:
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");
回答5:
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.

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)

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.

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);

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.

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.
回答11:
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.addHeaderView(yourview);
回答12:
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)
回答13:
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
