android.support.v7.widget.Toolbar pushes content to the bottom

Question

android.support.v7.widget.Toolbar seems to push the content to the bottom, check out these screenshots:

This screen is the original state when switching to the fragment:

After scrolling down a little bit I can see the full layout:

So how can I prevent the scrolling? If I remove android.support.v7.widget.Toolbar from the xml code everything works as expected (except for the missing toolbar lol).

This is the code of the main activity:

<?xml version="1.0" encoding="utf-8"?>
<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"
     xmlns:tools="http://schemas.android.com/tools"
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fitsSystemWindows="true"
     tools:context=".activity.MainActivity">

    <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.design.widget.TabLayout
            android:id="@+id/tabs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

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

    <android.support.v4.view.ViewPager
        android:id="@+id/container"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        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"
        android:src="@android:drawable/ic_menu_add"/>

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

And heres the code of the chat fragment:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:orientation="vertical" >

    <android.support.v7.widget.RecyclerView
        android:id="@+id/list"
        android:scrollbars="vertical"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:divider="@null"
        android:stackFromBottom="true"
        android:transcriptMode="normal" />

    <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:background="#ffffff"
        android:orientation="horizontal"
        android:padding="2dp" >

        <EditText
            android:id="@+id/enter_message"
            android:layout_width="0dip"
            android:layout_height="wrap_content"
            android:layout_marginRight="5dp"
            android:layout_weight="0.85"
            android:hint="hint"
            android:inputType="textCapSentences|textMultiLine"
            android:maxLines="5" />

        <Button
            android:id="@+id/send_button"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_gravity="center"
            android:layout_marginRight="5dp"
            android:background="@drawable/common_google_signin_btn_icon_dark_normal" />
    </LinearLayout>

</LinearLayout>

Removing android:fitsSystemWindows="true", as suggested in other threads, didn't change anything. Thanks in advance!

I’m not sure I got your desired behavior. You probably want to leave the layout as is but just remove the scroll flags from the toolbar:

app:layout_scrollFlags="scroll|enterAlways"

These flags tell the toolbar to listen to scrolls on the recycler view and react accordingly. As I understand, you want the toolbar to stay fixed. So, remove that line.
