When android:background="#ffffff" is used, first output is observed but the other elements like TextView are not visible.
When android:background="#ffffff" is not used, second output is observed but the other elements like TextView are not visible.
How do I solve this error?

why use fragment for fragment_navigation_drawer????
use from standard code of android studio, like below:
<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_main"
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_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
and make another xml for your toolbar and content like below:
<android.support.design.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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_home_page" />
</android.support.design.widget.CoordinatorLayout>
I hope it can help you.

In your app_bar_ipuclari.xml file you didn't close the tag
<include layout="#layout/content_ipuclari_sayfasi"/
add this > in the end.
Also try to move Toolbar into AppBarLayout

Android layouts overlap

I am including 2 layouts on my activity xml, now I want the second layout to not to overlap the first one but I do not really manage to do it....

include both layouts in

<include layout="#layout/content_youtube"
android:layout_marginTop="15dp"
android:layout_below="#id/header"
android:layout_width="match_parent"

Place both the "include" in one RelativeLayout and give relative margin between them using either
android:layout_marginTop="15dp"
or
android:layout_marginBottom="15dp"

Error with Toolbar

Sorry my bad English.
I have the following "activity_main.xml" file, the problem is that the Toolbar NOT appears, someone tells me how to make her look?
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
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="match_parent"
>
<RelativeLayout
android:id="#+id/anchor_point"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/holo_blue_light"
/>
</RelativeLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:elevation="4dp"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/menu_main"/>
</android.support.v4.widget.DrawerLayout>
with this other "activity_main.xml" Toolbar appears, but lacks the Navigation Drawer
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res /android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:ads="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/holo_blue_light"
>
</android.support.v7.widget.Toolbar>
<RelativeLayout
android:layout_below="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/container">
</RelativeLayout>
</RelativeLayout>

Try this way it will work
<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="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="#dimen/abc_action_bar_default_height_material"
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"/>
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Real content goes here -->
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- The navigation drawer -->
<android.support.design.widget.NavigationView
android:id="#+id/navigation"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:menu="#menu/drawer"/>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
