Is there any way to control views inside NavigationView header?

Question

As the title says, I want to know if there is any way to control views inside the NavigationView header? (Except for adding or removing header.)

For exa

Answer 1

Since i can not accept a comment as an answer. So, i repost Moinkhan' answer here:

first create header XML like lay_header.xml

<TextView
    android:id="@+id/tvThought"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

on your java file inflate this above header in a TextView. like

TextView headerView = (TextView) LayoutInflater.from(this).inflate(R.layout.lay_header, null);
headerView.setText("Your_thoght");

Now add it as a HeaderView

navView = (NavigationView) findViewById(R.id.navView);
navView.addHeaderView(headerView);

Thats it...

Many thanks! And again, we need a function that allow user to accept a comment as answer!

Simply try find your view in your activity:

tvUserName = (TextView) findViewById(R.id.tv_username);

It works for me. My header layout is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="192dp"
    android:background="?attr/colorPrimaryDark"
    android:padding="16dp"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:orientation="vertical"
    android:gravity="bottom">

    <TextView
        android:id="@+id/tv_username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:textAppearance="@style/TextAppearance.AppCompat.Body1"/>

</LinearLayout>

My NavigationView in Activity Layout is:

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_height="match_parent"
    android:layout_width="wrap_content"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/drawer_header"
    app:menu="@menu/menu_drawer"/>

And BTW, I came across problem when inflating LinearLayout, where layout params are not provided:

TextView headerView = (TextView) LayoutInflater.from(this).inflate(R.layout.lay_header, null);
headerView.setText("Your_thoght");

Hope it helps.

Answer 3

After updating your support library to version 23.1.1 or above,

You could do this -

View header = navigationView.getHeaderView(0);
TextView text = (TextView) header.findViewById(R.id.textView);

or if you have multiple headers

navigationView.getHeaderCount()

Answer 4

The other way to make this is using the method "inflateHeaderView()" of NavigationView object, like below (After using "setContentView()"):

View headerLayout = navigationView.inflateHeaderView(R.layout.yours_nav_header_layout);

After this point you can use "headerLayout" to access custom views in your header layout, like below:

View cutomView = (TextView) headerLayout.findViewById(R.id.lay_sign_in);

In my case i'm using ButterKnife framework to inject View "navigationView" like this:

@Bind(R.id.nav_view) NavigationView navigationView;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ButterKnife.bind(this);
    }
