XML and NavigationView Positioning

I have made a layout in which I have created a toolbar of my own in XML and I have set the Navigation View according to my requirement. I want that after clicking the hamburger icon the topleft , navigationView content should be displayed along with the back button on the topleft. I am able to make the content in the navigation View Visible but not the back button. Because the Navigation View is overlapping on my toolbar and the back button gets behind or underneath the navigation view. I am not getting the way to sort this out in XML. help me in this situation.
Code for the XML layout is given below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

you must set toolbar in an other parent layout test below code:

Design wrong of navigation drawer in tabbed Activity

I have a problem with my navigationdrawer of my tabbedActivity.
I have a problem of design if I can say like that.
When I open the navigation drawer, I'd like that he opens like this (this is another activity of my app) :
But instead it opens like this in my tabbed activity :
How can I move down my navigation drawer so it doesn't cut the title of my activity ?

You should move your toolbar to outside of the drawerLayout.
Since now the toolbar is having drawerLayout as its parent, that's why its showing like this.

Why my Tab Layout and Toolbar are showing like this?

As you can see in the image. These two are not aligned properly. I am not able to understand why this is happening.
My toolbar is in Coordinator Layout in app_bar_main.xml and my Tab Layout is in fragment_main. I didn't add the tab layout in coordinator layout because I don't want to show it in all my views, just in my fragment main file.
My code in app_bar_main.xml:
<android.support.design.widget.CoordinatorLayout

app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent">

</android.support.design.widget.CoordinatorLayout>
Code in fragment_main.xml:

android:layout_width="match_parent"
android:layout_height="match_parent"

Can you tell what I am doing wrong?
Image

For those who were not able to solve this.
I was able to solve it through an approach.
I added the above code in Main Activity and then set the visibility of tablayout and Toolbar in other fragments as GONE and in fragment which I want it to enable as VISIBLE.
To set visibility as gone you do:
TabLayout tabLayout = (TabLayout) getActivity().findViewById(R.id.tabs);
tabLayout.setVisibility(View.GONE);
ViewPager viewPager = (ViewPager) getActivity().findViewById(R.id.view_pager_1);
viewPager.setVisibility(View.GONE);
And to set it as visible just replace GONE with VISIBLE.

app_bar_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/main_content"
android:layout_width="match_parent"

fragment_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="50dp"
app:tabMode="fixed"
app:tabGravity="fill"
app:tabTextColor="#color/empty_area"
app:tabSelectedTextColor="#android:color/white"
app:tabIndicatorColor="#android:color/white"
android:background="#color/colorPrimary" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/tab_layout" />
<View

android:layout_width="match_parent"
android:layout_height="3dp"
android:layout_below="#+id/tab_layout"
android:background="#drawable/shadow_bottom" />
</RelativeLayout>
The other way, as you mentioned is to put the tab layout inside the AppBarLayout in app_bar_main.xml

Android TabLayout not visible on my application

I'm trying to add simple TabLayout on my application, but it doesn't visible, view pager work fine
this layout is toolbar_layout
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
android:titleTextColor="#ffffff"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="#+id/tabsLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
and my main layout is:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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:background="#drawable/content_background">
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/application_toolbar"/>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="-25dp"
android:layout_marginRight="-25dp"
/>
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/header"
app:menu="#menu/drawer"/>
<com.lapism.searchview.SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"/>
</android.support.v4.widget.DrawerLayout>
</android.support.design.widget.CoordinatorLayout>
as i said view pager work fine, but tabs not visible on my application

TabLayout should not be in Toolbar.
Check this repository as sample of using CoordinatorLayout, DrawerLayout, Toolbar, TabLayout.
Here is activity_main.xml and include_list_view.xml.
The view hierarchy is like this:
DrawerLayout
- CoordinatorLayout
- AppBarLayout
- Toolbar
- TabLayout
- ViewPager
- NavigationView

Main Layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
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:background="#drawable/content_background">
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include layout="#layout/application_toolbar"/>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
<!-- Change this -->
android:layout_height="0dp"
android:layout_weight="1"
<!-- Code -->
android:layout_marginLeft="-25dp"
android:layout_marginRight="-25dp"
/>
</LinearLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/header"
app:menu="#menu/drawer"/>
<com.lapism.searchview.SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"/>
</android.support.v4.widget.DrawerLayout>
</android.support.design.widget.CoordinatorLayout>
The android:layout_height of the LinearLayout is set to match parent that hides the TabLayout. Change android:layout_height to 0dp and set android:layout_weight to 1. I think this may solve your problem.

That's because you put your TabLayout inside the Toolbar.
Try to change your toolbar_layout to this:
<android.support.design.widget.AppBarLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
android:titleTextColor="#ffffff"
app:layout_scrollFlags="scroll|enterAlways">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tabsLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabGravity="fill"
app:tabMode="fixed"/>
</android.support.design.widget.AppBarLayout>

Try this:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_height="match_parent"
android:layout_width="match_parent" />
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/action_bar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
<!-- Tabs-->
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
app:tabMode="fixed"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:tabTextColor="#d3d3d3"
android:minHeight="?attr/actionBarSize"
/>
</android.support.design.widget.AppBarLayout>
</FrameLayout>
The FrameLayout is the main content view of the activity.

I actually found someone else's answer here.
Tabs of TabLayout not showing
tabLayout.post(new Runnable() {
#Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
Hope this helps
