Duplicate value in the NavigationView title after updating the title text

Question

After updating the text and image title in the NavigationView title, I get a duplicate value in the NavigationView title.

Here is my piece of code

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { boolean doubleBackToExitPressedOnce = false; SQLiteHelper dbHelper; String setName, setMail; AlertDialog.Builder builder, builder_verify; public static int count = 0; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); setSupportActionBar(toolbar); dbHelper = new SQLiteHelper(getApplicationContext()); builder_verify = new AlertDialog.Builder(this); DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); ActionBarDrawerToggle toggle = new ActionBarDrawerToggle( this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); drawer.setDrawerListener(toggle); toggle.syncState(); NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); navigationView.setNavigationItemSelectedListener(this); View hView = navigationView.inflateHeaderView(R.layout.nav_header_main); ImageView iv = (ImageView) hView.findViewById(R.id.imageView); TextView headerName = (TextView) hView.findViewById(R.id.txtName); TextView headerMail = (TextView) hView.findViewById(R.id.textEmail); iv.setImageResource(R.drawable.logo); headerName.setText("TEST"); headerMail.setText(" [e-mail] "); } } 

In the code above, I added a view to update the title text. I also added the main XML code below

 <?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"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <include layout="@layout/app_bar_main" android:layout_width="match_parent" android:layout_height="match_parent" /> <FrameLayout android:id="@+id/flContent" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout> <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:headerLayout="@layout/nav_header_main" app:menu="@menu/activity_main_drawer" /> </android.support.v4.widget.DrawerLayout> 

Also added a navigation header layout

nav_header_main.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="@dimen/nav_header_height" android:background="@drawable/side_nav_bar" android:gravity="bottom" android:orientation="vertical" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" android:theme="@style/ThemeOverlay.AppCompat.Dark"> <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:paddingTop="@dimen/nav_header_vertical_spacing" android:src="@drawable/logo"/> <TextView android:id="@+id/txtName" android:layout_width="match_parent" android:layout_height="wrap_content" android:paddingTop="@dimen/nav_header_vertical_spacing" android:text="Sample" android:textAppearance="@style/TextAppearance.AppCompat.Body2" android:textStyle="bold" /> <TextView android:id="@+id/textEmail" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Sample Inc." /></LinearLayout> 

I also added a screenshot for reference

Right now, I see no way to change the headerview. Any suggestions to avoid duplicate text and header images?

Many thanks!

Answer 1

Good question.

Fix this instead of pumping up the title (it's already overpriced!) On navigationView.inflateHeaderView(R.layout.nav_header_main); get it from NavigationView using the getHeaderView(int index) method, and then populate it.

Here's the code to run:

  navigationView.setNavigationItemSelectedListener(this); View hView = navigationView.getHeaderView(0); ImageView iv = (ImageView) hView.findViewById(R.id.imageView); TextView headerName = (TextView) hView.findViewById(R.id.txtName); TextView headerMail = (TextView) hView.findViewById(R.id.txtEmail); iv.setImageResource(R.drawable.logo); 

Answer 2

In xml fie you already installed

  app:headerLayout="@layout/nav_header_main" 

for NavigationView and again in the java class you inflate your view with

 View hView = navigationView.inflateHeaderView(R.layout.nav_header_main); 

So there are duplicate values ​​in the NavigationView .

I have an easy solution to this problem and it works for me. Before adding titles, we must remove the current types of titles from the navigation box. This is a piece of code.

 if (navigationView != null) { for (int i = 0; i < navigationView.getHeaderCount(); i++) { if (navigationView.getHeaderView(i) != null) navigationView.getHeaderView(i).setVisibility(View.GONE); } addHeaderLayout(navigationView); }
