android:layout_height="match_parent"
android:layout_weight="1"
android:background="#android:color/holo_orange_light"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>

How can i put the element RecyclerView under the element Toolbar in the Android Layout file?

Hey i want in my android app that the recyclerlistview and the floatingActionButton not cut the toolbar. Here is my Layout:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
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">
<include
layout="#layout/toolbar_task_layout">
</include>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView_task"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
app:layout_anchor="#id/recyclerView_task">
</android.support.v7.widget.RecyclerView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/floatingActionButton_task_openDialog_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_margin="16dp"
android:src="#drawable/ic_add_black_36dp"
app:layout_anchor="#id/recyclerView_task"
android:clickable="true"
app:fabSize="normal"
app:layout_anchorGravity="bottom|right|end"/>
</android.support.design.widget.CoordinatorLayout>
Here you can see the problem:
Update:
Here is the toolbar layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar 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="wrap_content"
android:id="#+id/toolbar_task"
android:layout_alignParentTop="true"
android:background="?attr/colorPrimary"
android:elevation="6dp"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="0 items selected"
android:id="#+id/counter_task"
android:textSize="18dp"
android:textColor="#ffffff"
android:textStyle="bold" />
</RelativeLayout>
</android.support.v7.widget.Toolbar>

Try replacing your <include layout="#layout/toolbar_task_layout"></include>
with this:
<include layout="#layout/toolbar_task_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
EDIT: I assume you also want your FAB to be on the bottom right since this is the norm, try setting android:layout_alignParentBottom="true" and android:layout_alignParentRight="true" in your FAB and make the RecyclerViews height match_parent

try this make your toolbar android:layout_height to android:layout_height="?attr/actionBarSize"
<android.support.v7.widget.Toolbar
android:id="#+id/ac_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="exitUntilCollapsed"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" >

Use below code:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
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:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/toolbar_task_layout"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView_task"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp"
app:layout_anchor="#id/recyclerView_task"
android:layout_below="#+id/toolbar_task"/>
</RelativeLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/floatingActionButton_task_openDialog_"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right"
android:layout_margin="16dp"
android:src="#mipmap/ic_launcher"
app:layout_anchor="#id/recyclerView_task"
android:clickable="true"
app:fabSize="normal"
app:layout_anchorGravity="bottom|right|end"/></android.support.design.widget.CoordinatorLayout>
I hope this will help.....

Row of Listview hidden

i need to create a listview into a framelayout.
This is my code:
<FrameLayout
android:id="#+id/layout_ejercicios"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_alignParentStart="true"
android:layout_below="#+id/layout_info"
android:orientation="vertical">
<ListView
android:id="#+id/listViewEjercicios"
android:layout_width="match_parent"
android:layout_height="match_parent"></ListView>
<include
android:id="#+id/tool_bar_ejercicios"
layout="#layout/toolbar" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fabCrearEntrenamiento"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="16dp"
android:clickable="true"
android:src="#drawable/ic_action_add"
app:fabSize="normal"
app:layout_anchor="#id/layout_ejercicios"
app:layout_anchorGravity="bottom|right|end" />
</FrameLayout>
It works almost fine but the first row always is hidden by the toolbar.
The rest rows look good.
I try to add padding_top in the row_layout.xml, but is no a solution.
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/rowTextView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="21sp" >
</TextView>
How can i do that?

try this;
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

</FrameLayout>
</android.support.design.widget.CoordinatorLayout>

You used a FrameLayout. Yes, all views overlap in a FrameLayout. Use a LinearLayout because you have set orientation="vertical"
You should put Toolbar above other things
CoordinatorLayout would be better
For example,
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/tool_bar_ejercicios"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>
<!-- Some other layout behind the Action Button -->
<include layout="#layout/list_view"/>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fabCrearEntrenamiento"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|right|end"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_action_add"/>
</android.support.design.widget.CoordinatorLayout>

Having trouble in GridView Layout

I have this 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:fitsSystemWindows="true"
tools:context="com.example.anandvardhan.albumview040416.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>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

</GridView>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email"/>
</android.support.design.widget.CoordinatorLayout>
But now I am getting a preview like this:
So how to select an item at position 1, because it must be beneath the toolbar.
And one more thing.
If my GridView is initially empty then it must show a TextView in centre of the
screen stating "It's Empty". How to set it dynamically.
I will be very thankful if anyone could help.

Tell me if you have any question,
<?xml version="1.0" encoding="utf-8"?>

Use RecyclerView and set Layout Manager as GridLayoutManager.
Here's the xml
<?xml version="1.0" encoding="utf-8"?>
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.anandvardhan.albumview040416.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>
<android.support.v7.widget.RecyclerView
android:id="#+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingTop="#dimen/activity_vertical_margin"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<!-- Your Empty view here -->
<android.support.design.widget.FloatingActionButton
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_marginBottom="20dp"
android:layout_marginRight="20dp"
app:backgroundTint="#color/button_background_dark_red"
android:src="#drawable/ic_action_new"
app:borderWidth="0dp"
app:elevation="6dp"
app:fabSize="normal"/>
</android.support.design.widget.CoordinatorLayout>
To use GridLayoutManager with RecyclerView, please check this site
If there's no data, you can set the visibility of RecyclerView to View.GONE and set the visibility of empty view to View.VISIBLE

Coordinator Layout and Relative Layout issue

When you create a blank Activity in android studio, this is the given 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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.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_main" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
And the Relative layout (#layout/content_main) goes out of screen:
If you set a button in your relative layout, with layout_alignParentBottom the button sometimes will go out of screen. (It doesn't happen all the time, I have no idea why)
#layout/content_main
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:context="com.example.MainActivity"
tools:showIn="#layout/activity_main">
<Button
android:id="#+id/button"
android:layout_alignParentBottom="true"
android:layout_width="match_parent"
android:layout_height="70dp"
android:background="#color/green"
android:textColor="#color/white"
android:text="text"
android:focusable = "true"
android:focusableInTouchMode = "true"
/>
</RelativeLayout>
Adding Padding bottom to the relative layout won't work. (As it'll only work when the button is off the screen)
I need the button to be at the bottom of the screen always. Can someone tell me how to achieve this?
Like this:

Try the following code, this will keep that button at the end without going to out of the view:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.example.android.myapplication.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>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</android.support.design.widget.CoordinatorLayout>
And the Relative layout (#layout/content_main) goes out of screen:
Edit: i think that's because you've set them match_parent.try something like this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button

android:focusableInTouchMode="true"
android:text="text"
android:textColor="#android:color/white" />
</RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

In
#layout/content_main try to remove the following line
app:layout_behavior="#string/appbar_scrolling_view_behavior"
