Question

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.

Answer 1

NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.addHeaderView(yourview);

Answer 2

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);

   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

Answer 4

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)

Answer 5

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.

Answer 6

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.
