I apply onCreatePost()

And many method apply such as configuration and other but there is not a solution.so how can I fix this problem.. in my system install Androidx

Answer 1

I had the same issue and I fixed it by adding the navigation graph into the Hosted Fragment, I'll post the layout code from the main view.

main.xml

    <?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">

<!-- This layout contains the Action App Bar see the app_bar_main.xml code-->
        <include
            layout="@layout/app_bar_main"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />

<!-- This is the Navigation drawer widget, Which opens when you click on the hamburger icon -->
<!-- For that you could add header view -->
<!-- Can add menu or custom view for navigation tabs -->
        <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">
            <include layout="@layout/nav_body_main"/>
        </com.google.android.material.navigation.NavigationView>

    </androidx.drawerlayout.widget.DrawerLayout>

app_bar_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
    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/root_landing"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".ui.landing.main.MainActivity">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:theme="@style/AppTheme.AppBarOverlay">

            <androidx.appcompat.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:background="@android:color/transparent"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

    </com.google.android.material.appbar.AppBarLayout>

    <include layout="@layout/content_main" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

content_main

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:showIn="@layout/app_bar_main">

    <fragment
        android:id="@+id/nav_host_fragment"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:defaultNavHost="true"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:navGraph="@navigation/mobile_navigation"/>
<!--  This navigation graph will sort the issue -->
</androidx.constraintlayout.widget.ConstraintLayout>

And find the Activity Code.

// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.

 mAppBarConfiguration = new AppBarConfiguration.Builder(
          R.id.nav_home, R.id.nav_gallery, R.id.nav_slideshow,
           R.id.nav_tools, R.id.nav_share, R.id.nav_send)
           .setDrawerLayout(drawer)
           .build();

    navController = Navigation.findNavController(this, R.id.nav_host_fragment);
    NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
    NavigationUI.setupWithNavController(navigationView, navController)

Easiest Way

The easiest way is to generate the code through the Android Studio since you are new.

RightClick on the Package folder -> New -> Activity -> Gallery

from that select Navigation Drawer Activity

Cheers!
