Simple, I have a navigation drawer (auto generated by the andorid studio assistant) happens that he generates his main activity which calls the drop-down menu and this in turn is divided into 2 sections ie the header and the body ( that is, the layout invokes another layout) here is where my question is, I want to modify part of the header with any String supplied by the user.
MenuCentral.java class which contains the MenuDrawer

as you can see the flame at activity_menu_central.xml which is the following.
activity_menu_central.xml
<?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_menu_central"
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:headerLayout="@layout/nav_header_menu_central"
app:menu="@menu/activity_menu_central_drawer" />
</android.support.v4.widget.DrawerLayout>
which looks like this ...
as you can notice in the xml the layout calls app:headerLayout="@layout/nav_header_menu_central" and in the there is the TextView that I want to modify which is the following ...
nav_header_menu_central.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
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"
app:srcCompat="@android:drawable/sym_def_app_icon" />
<TextView
android:id="@+id/textViewCabeza"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/nav_header_vertical_spacing"
android:text="Bienvenido"
android:textAppearance="@style/TextAppearance.AppCompat.Body1" />
<TextView
android:id="@+id/textviewcorreo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="*AQUI VA EL NOMBRE*" />
</LinearLayout>
The problem is the following ... MenuCentral.java call activity_menu_central.xml and this invokes the menu, I want to modify the text located in the header " HERE GOES THE NAME "in the xml nav_header_menu_central with my variable" mail "from the MenuCentral
