I am trying to create a tool bar associated with an EditText on my scren. Below are the contents of my xml file that I am trying to create:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tool="http://schemas.android.com/tools"
tool:context=".CreatePost"
android:id="#+id/create_post">
<include layout="#layout/app_bar" android:layout_width="match_parent" android:layout_height="wrap_content"
android:id="#+id/create_post_toolbar"/>
<!-- Edit text for typing status. Light gray placeholder. -->
<EditText
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textColorHint="#d3d3d3"
android:layout_below="#id/create_post_toolbar"
android:hint="Update your friends!"
android:padding="10dp"
android:gravity="top"
android:background="#android:color/transparent"
android:inputType="textMultiLine"
android:id="#+id/type_status"/>
</RelativeLayout>
app_bar.xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

android:background="?attr/colorPrimary" app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
However, when I do this, my EditText covers my toolbar. Here is an image to show what happens:
I don't really understand why this is happening, is there anyway to align my EditText so it doesn't cover the toolbar? Thanks!
UPDATE: after adding in Arya's code into mine, my image looks like so, which makes the ActionBar too high. Any ideas on how to fix it?
Your layout, in its current definition, does not make much sense. I think the problem here is that the CoordinatorLayout has been assigned fitsSystemWindows=true. This makes it report its bottom from the very top of the status-bar. On the other hand, the RelativeLayout expects the bottom value from the bottom of the status-bar. This makes your EditText overlap the Toolbar by 25dp - the standard height of a status-bar. You can kind of confirm this by assigning android:fitsSystemWindows="true" to your RelativeLayout with id create_post. In this case, the bottom for CoordinatorLayout will be reported correctly, and the EditText will not overlap the Toolbar.
Usually, the CoordinatorLayout is set to be the parent, and the content (in your case the RelativeLayout) resides as a child of the CoordinatorLayout:

I would like to know why this toolbar cast a shadow only if NestedScrollView is there (I've got this example from the internet)
<android.support.design.widget.CoordinatorLayout

android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<!-- Your scrolling content -->
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:local="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"

This toolbar (without the NestedScrollView) don't cast any shadow:

I can post pictures, if needed, but I have no clue why this happen.
This is what I've tried so far:
Setting clipToPadding="false" on the parent Linear Layout
Manually set elevation (my device is not Pre-Lollipop)
Seting outlineProvider="bounds" on the view
Setting android:hardwareAccelerated="true" on the AndroidManifest.xml
Edit: I've solved it by using the tag. Check my answer with the code.
Researching a little bit more, I found out that the merge tag will do the trick. This tag can merge the toolbar.xml in the parent layout that will take care of the z-ordering and place the Toolbar where I intended.
<merge xmlns:android="http://schemas.android.com/apk/res/android"

local:popupTheme="#style/ThemeOverlay.AppCompat.Light"
/>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
</merge>
And no, asking here was not the first thing I did, It was just luck to find this tag in less than an hour after I post here. Anyway, here is my solution.
I have a Coordinator Layout, which contains AppBar Layout and one Relative Layout.
Relative layout contains one ScrollView and a EditText.
Firstly, Whenever I used to tap edit text to input text, keyboard open up and hid the edit text field. ActionBar is visible on the top.
When I set android:windowSoftInputMode="adjustResize" in manifest for the activity, edit text field is still hidden behind the keyboard. Actionbar is visible at screen top.
But When I set android:windowSoftInputMode="adjustPan", my Edittext field was visible just above the keyboard, but now Actionbar goes out of screen.
I want to have action bar always visible and edit text field visible above keyboard.
Please help me with the fix!

I have a custom view that scrolls vertically using a ScrollView but when I put it inside of an android.support.v7.widget.Toolbar it will no longer scroll. The same thing happens if I use a NestedScrollView too. Is it possible to use a ScrollView inside of a Toolbar? If not, then are there alternative approaches to achieve the same thing?
Here's some example code of what I'm doing:
<?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.me.ExampleActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="#dimen/appbar_padding_top"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay">
<com.me.NormallyScrollableView
android:id="#+id/myView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
In short, not with the AppBarLayout. You have to remove that in order to get the desired scroll inside of the toolbar.
your view hierarchy should be 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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.me.ExampleActivity">
<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">
<com.me.NormallyScrollableView
android:id="#+id/myView"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.v7.widget.Toolbar>
<!-- Have to create Margin, since AppBarLayout is not first view in Coordinator layout (which it expects) -->
<FrameLayout
android:layout_marginTop="?attr/actionBarSize"
android:layout_height="match_parent"
android:layout_width="match_parent">
</FrameLayout>
</android.support.design.widget.CoordinatorLayout>
But at this point, CoordinatorLayout is useless for this screen in your app...
So to some up, its not possible with the view hierarchy you have setup.
Good Luck and Happy Coding!
I think it's not possible to do that but I suggest to use this
<?xml version="1.0" encoding="utf-8"?>

I'm new to Android development and I'm facing the following issue.
This is the layout of my main activity:
<?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.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:tabIndicatorColor="#color/white"
app:tabTextColor="#color/selected_text"
app:tabSelectedTextColor="#color/white"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/main_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
For each tab in the ViewPager I have a fragment, and this is the layout of one of them
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/colorPrimary"
android:id="#+id/linear_layout"
tools:context=".fragments.Reviews">
<RatingBar
android:id="#+id/review_totalRating"
style="?android:attr/ratingBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:numStars="5"
android:stepSize=".5"
android:isIndicator="true"
android:progressTint="#color/golden"
android:layout_gravity="center"
android:paddingTop="10dp"
android:paddingBottom="5dp" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:divider="#android:color/transparent"
android:dividerHeight="8dp"
android:paddingLeft="8dp"
android:paddingRight="8dp"
android:id="#+id/listView_reviews" />
</LinearLayout>
Then I populate my ListView with items whose layout is defined in another xml file. My problem is with the ViewPager layout_height: it is now set to match_parent, but the element extends over the bottom of the screen, with the result that the last element of the ListView is covered by the navigation buttons.
This is what I see in the design editor
ViewPager overflow
How can I make the element stop before the navigation buttons?
I faced this issue too. It's because of AppBarLayout behavior in CoordinatorLayout. By default when you create a project from a template it will set up layout with hiding Toolbar. You can run your example and check it - just swipe toolbar up and it will hide and ViewPager will move up and then correctly sticks to the bottom of the screen.
It's not a solution for some cases so you can disable this behavior by removing app:layout_scrollFlags attribute from your Toolbar. After this, the toolbar will become unhideable and the ViewPager will calculate own height correctly.
I solved using a LinearLayout as the only child of the CoordinatorLayout, so everything else becomes a children of the LinearLayout. It seems to me to be just a simple workaround, not a final solution, but now it works. This is now the layout of my main activity:
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent">

android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_main"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:elevation="4dp"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:tabIndicatorColor="#color/orange_050"
app:tabSelectedTextColor="#color/orange_050"
app:tabTextColor="#color/orange_050"/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/main_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</LinearLayout>
I'm working on a tab activity in my app, but it seems that the tabs are using the wrong height (thinking the layout is about half an inch taller than it is on any device) and as a result any vertical centering is off on the low side, and my scrollviews are messed up because the screen won't scroll far enough down to see the bottom of the view. I have tried tinkering with the layout_height on any relevant class I can think of and hiding the tabs, but nothing helps and I cant find this problem anywhere else. I generated the default template for a TabLayout activity in Android Studio 1.4.

On activity_main you can create a RelativeLayout. Put your ViewPager and AppBarLayout inside RelativeLayout and set your ViewPager like this:
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/appbar"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"
app:layout_scrollFlags="scroll|enterAlways">
</android.support.v7.widget.Toolbar>
you have to wrap content for the widget.toolbar
