I know this may be a stupid question, however as a newbie i cant get to work around it.
So i want to add actionBar with Back Navigation Button and part of LinearLayout is hidden. How could i solve the problem ??

<!--Add Product-->
<Button

android:layout_height="wrap_content"

</LinearLayout>
Expectation
I manually set margin-top to lower Linearlayout and show the expected result.
You need to add the layout behaviour to your content
<include layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
You can try this. Since you are using CoordinatorLayout you need to use layout_behaviour, layout_anchor and layout_anchorGravity to properly align the layout. Just add the following line in your include:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
So it will be like this:
<include layout="#layout/content_main"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>

I am new to Android, but experienced at Java. Building a basic app and I want to add a RecyclerView (Found the tutorial for it here) along with the "Basic Activity" template layout.
When I add the RecyclerView in the XML, the items are hidden behind the top bar (first XML file and first Image), but when I move it to within the top bar, the text is removed (second XML file and second Image).
How do I fix this so that the text shows?

You have two issues with your XML.
There is an extra LinearLayout tag that is never closed, so this shouldn't even build. You shouldn't need this and should be able to delete it.
If you want the TextView below the ImageView you need to set constraints on the TextView so it does just that.
So at minimum, you need something like this:
<?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" // <- App namespace
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center">
<ImageView
android:id="#+id/articleImage"
android:layout_width="400dp"
android:layout_height="185dp" />
<TextView
android:id="#id/articleAuthor"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/article_author"
app:layout_constraintTop_toBottomOf="#+id/articleImage" /> // <- Constraint
</android.support.design.widget.CoordinatorLayout>
I strongly recommend reviewing the ConstraintLayout documentation:
https://developer.android.com/training/constraint-layout
https://developer.android.com/reference/android/support/constraint/ConstraintLayout
Hope that helps!

My app contains a SwipeRefreshLayout with a listView inside of it. The list receives data from a server. So when the data is fetched and the list is populated correctly the swipe to refresh works, but when the data is not passed to the list and is empty the SwipeRefresh doesn’t work. Why can’t I swipe when the listView is empty?
That‘s my layout:

Your listview and the swipe refresh layout is within a nested scroll view which means the height of child of the nested scroll view becomes wrap content (Relative layout in your case) automatically (It also might be showing you a lint warning to replace the match parent height of your relative layout to wrap content).
therefore when there's no data in your list, the height of the whole layout group becomes 0 and the place where you need to swipe to refresh has a height of 0 and you cant swipe within a layout of height zero.
To solve this you can take a linear layout above your nested scroll view with the height of match parent and put your swipe refresh layout over it.
Let me know if you need the example code.
EDIT
Okay! so this is a workaround I found to solve the issue. You can try this and please let me know if this solves your problem.
The Idea is to wrap everything a swipe refresh layout.

I've been for stuck hours because of my Snackbar pops out in front of the bottom navigation bar.
Is there something wrong with my layout?
Is it the nesting of the layout?
Any answers are appreciated, thanks :D

You are using the coordinator widget in the wrong way. Always Remember the hierarchy of coordinator's children must be:
<CoordinatorLayout>
<Appbar/>
<View/> <!--Mostly NestedScrollView or something scrollable-->
<fab/> <!--Optional-->
<bottomBar/> <!--Optional-->
</CoordinatorLayout>`
So your main_layout.xml must be changed as:
<android.support.v4.widget.DrawerLayout>
.
.
.
<android.support.design.widget.CoordinatorLayout
android:id="#+id/overview_coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimaryDark"
app:popupTheme="#style/PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_home" />

app:layout_constraintRight_toRightOf="parent"
app:menu="#menu/navigation" />
</android.support.design.widget.CoordinatorLayout>
.
.

</android.support.v4.widget.DrawerLayout>
And for showing the SnackBar use this code:
Snackbar.make(findViewById(overview_coordinator_layout), "Hello!", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();

It's been a while, but I managed to solve it so here is the code:
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="#dimen/app_bar_height">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
app:title="Title" />
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:expandedTitleTextAppearance="#style/TextAppearance.AppCompat.Title">
<!-- Action bar content -->
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<!-- scrollable content -->
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
... />
</android.support.design.widget.CoordinatorLayout>
