In Swift, we can use a Library called "SideMenu" to show a viewController on the SideMenu.
Now, I'm coding in Android. I want to display activity in the NavigationView we can only display a Menu or header. I cannot show an activity or fragment on the NavigationView.
Can you help me or give me some advice about this problem?
Android app can display one activity at once (it's changed recently but in your scenario it's still true). In your case you should inflate View or Fragment. Just put your layout or fragment inside NavigationView:
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.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" />
<com.google.android.material.navigation.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">
<TextView
android:text="Custom View"
android:layout_gravity="center"
android:background="#ff0000"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
NavigationView extends FrameLayout so if you will inflate menu it will overlap. Because of that you may want to delete:
app:headerLayout="@layout/nav_header_main"
app:menu="@menu/activity_main_drawer"
If you are using the android navigation component you can see the full detailed information to achieve this and replacing the fragments to corresponding to user clicks/choices drawer layout with navigation component
if you aren't using the android navigation component and just using the drawer layout you can see this drawer layout
