CoordinatorLayout + AppbarLayout + Viewpager not resize child layout

Question

I have a problem using CoordinatorLayout in conjunction with ViewPager and the ViewPager:

the layout does not resize correctly. Supose that the height solved includes tabs height. So when I scroll to bottom i see this:

main layout code:

<?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:id="@+id/coordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context=".activities.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar_layout"
        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:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <FrameLayout
        android:id="@+id/root_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <include layout="@layout/content_main" />
    </FrameLayout>

    <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>

tab layout code

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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=".activities.MainActivity"
    tools:showIn="@layout/activity_main"
    android:orientation="vertical">

    <android.support.design.widget.TabLayout
        android:id="@+id/tab_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

    <FrameLayout
        android:id="@+id/regularLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <android.support.v4.view.ViewPager
            android:id="@+id/pager"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
    </FrameLayout>
</LinearLayout>

child layout code

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary"
    android:clickable="false"
    android:orientation="vertical">

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_gravity="bottom"
        android:layout_marginRight="85dp"
        android:src="@drawable/ic_android" />

</RelativeLayout>

Any idea? I saw several posts but could not find the problem, I need that the height of child must be screenHeight - actionBarHeight - TabBatHeight

It seems a double fitsystemwindow's padding issue. Can you post your layout? — GPack, Apr 14 '16 at 06:51
@GPack check the link "child layout code" on the end of answer. — Gaston Flores, Apr 14 '16 at 13:04

There are several things to consider when using CoordinatorLayout + AppBarLayout + ViewPager:

Place ViewPager Inside CoordinatorLayout but Outside AppbarLayout
Only ViewPager should set its behavior to app:layout_behavior="@string/appbar_scrolling_view_behavior" put
Place TabLayout inside AppBarLayout
You can also set scroll flag on the AppBarLayout direct children
set android:fitsSystemWindows="true" on both CoordinatorLayout & AppBarLayout so your scrim color can be applied to status bar

so your final layout probably should looks like this (it doesn't include your child layout because I guess it was your ViewPager Page) :

<?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:id="@+id/coordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay"
        android:fitsSystemWindows="true">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:layout_scrollFlags="scroll|enterAlways" />

    </android.support.design.widget.AppBarLayout>


    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior" />

    <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 here are several resource you should definitely check out:

Wow great answer, but not worked for me: (1) My viewpager is in a FrameLayout that is in CoordinatorLayout, (2) The FrameLayout has a beahvior because all layouts will be loaded inside it, (3) I put TabLayout inside AppBarLayout but not works, the background color of tabbar and actionbar is the same [see](http://postimg.org/image/x5fhvh1vl/) (4) setting scroll flag and android:fitsSystemWindows not works to. — Gaston Flores, Apr 12 '16 at 13:46
I still don't get why you cannot use TabLayout inside AppBarLayout? — Behzad Bahmanyar, Apr 12 '16 at 17:54
@GastonF. (1) You can set different background color for TabLayout. and if you do that, you have your ViewPager directly inside CoordinatorLayout. (2) AppBarLayout is actually a custom Vertical LinearLayout so Toolbar and TabLayout won't overlap. — Behzad Bahmanyar, Apr 12 '16 at 18:03
I tried the Chris Banes sample but not working, still can not calculate the height correctly. — Gaston Flores, Apr 13 '16 at 14:56
I not use a tablayout inside a AppBarLayout because there is activities that not need it. — Gaston Flores, Apr 13 '16 at 16:04
Hey OP can you mark this as the accepted answer ? This definitely worked. thumbs up for the line by line instructions. — ralphgabb, Feb 28 '17 at 01:48
`Place ViewPager Inside CoordinatorLayout but Outside AppbarLayout` this advice fix my problem.. — mDonmez, Sep 25 '19 at 20:08

I had a similar problem and perfect solution was add

android:layout_marginBottom="?attr/actionBarSize

in layout with

app:layout_behavior="@string/appbar_scrolling_view_behavior"

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:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

<android.support.design.widget.AppBarLayout
    android:id="@+id/appbar"
    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="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|enterAlways"
        app:popupTheme="@style/AppTheme.PopupOverlay">

    </android.support.v7.widget.Toolbar>

</android.support.design.widget.AppBarLayout>

<android.support.v4.view.ViewPager
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="?attr/actionBarSize"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom"
    android:layout_margin="@dimen/fab_margin"
    app:backgroundTint="@android:color/holo_green_dark"
    app:srcCompat="@android:drawable/ic_input_add" />

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

You can use NestedScrollview in your child layout:

<android.support.v4.widget.NestedScrollView
    android:id="@+id/nest_scrollview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="fill_vertical"
    android:fillViewport="true"
    android:fitsSystemWindows="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

       <your layout>

</android.support.v4.widget.NestedScrollView>

Forcing requestLayout on the pager helped me solve this issue

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    ...
    mViewPager.post(new Runnable() {
        @Override
        public void run() {
            mViewPager.requestLayout();
        }
    });
}

I will suggest a Link to solve design problems:

Check tutorial

Use Main Layout like

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/coordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.Dark" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tablayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="?attr/colorPrimary"
            app:tabGravity="fill"
            android:theme="@style/ThemeOverlay.AppCompat.Dark" />

        <android.support.v4.view.ViewPager
            android:id="@+id/viewpager"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1"/>

    </LinearLayout>

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_gravity="bottom|right"
        android:layout_marginBottom="@dimen/activity_vertical_margin"
        android:layout_marginRight="@dimen/activity_horizontal_margin"
        android:src="@drawable/ic_done"/>

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

I have downloaded and edited a code but not working for me, i need that the child resize to the correct heigth. For example, i have two tabs, first tab has a simple layout and a second has a recyclerview. — Gaston Flores, Apr 20 '16 at 15:13
