You cannot do this in coordinatorlayout. so use RelativeLayout and within its design your own layout

try this

Answer 3

I faced same problem Here is the way That worked for me

Remove the AppBarLayout layout_behavior so it fixed on top. Define the FrameLayout layout_behavior as app:layout_behavior="@string/appbar_scrolling_view_behavior" so it adjust FrameLayout below the AppBarLayout. In this way way your content of frame layout will scroll but not toolbar. CoordinatorLayout layout like as follows

<?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.next_tech.teebox.GridView">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:titleTextColor="@android:color/white" />

    </android.support.design.widget.AppBarLayout>
<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">


</FrameLayout>


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

This is the XML of the your fragment Layout where your recyclerView scroll without affecting your TabLayout and bottom Linear Layout.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

        app:tabMode="fixed"
        app:tabMaxWidth="0dp"
        android:elevation="4dp"
        app:tabIndicatorColor="@color/btnBackground"

        android:layout_weight="1">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/list"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>
    </android.support.v4.widget.SwipeRefreshLayout>

    <LinearLayout
        android:id="@+id/toolbarselection"

        >

            android:layout_gravity="center"
            app:srcCompat="@android:drawable/ic_menu_delete" />
        <ImageView
            android:id="@+id/select"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_weight="1"
            app:srcCompat="@drawable/white_arrow" />

        <ImageView
            android:id="@+id/send"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:layout_gravity="center"
            app:srcCompat="@drawable/ic_send_holo_dark" />

    </LinearLayout>

</LinearLayout>

Answer 4

The best possible solution will be making this kind of hierarchy

<ConstraintLayout>
    <CoordinatorLayout>
        <AppBarLayout>
           <ToolBar>
           <TabLayout>
        </AppBarLayout>
        <Inlude>
        Your layout which will be used to hide the toolbar upon interaction.
        </Include>
    </CoordinatorLayout>

 
   Other Widgets needs to be placed at a fixed position.

</ConstraintLayout>

Don't forget to add

app:layout_behavior="@string/appbar_scrolling_view_behavior"

the above line into your include's parent ViewGroup.

Let's have an example of the approach that I am talking about

So far so good. Let's have a look at the result

Answer 5

You can try and add the collapseMode on yout toolbar something like this.

Your appBarLayout seems fine

I would advise u to look at this link: https://github.com/codepath/android_guides/wiki/Handling-Scrolls-with-CoordinatorLayout `

 <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@android:color/holo_blue_light"
        android:fitsSystemWindows="true"
        app:expandedTitleMarginEnd="64dp"
        app:expandedTitleMarginStart="48dp"
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

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

        <android.support.design.widget.TabLayout
            android:id="@+id/tablayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabIndicatorColor="@color/white"
          app:tabIndicatorHeight="@dimen/profile_tablayout_indicator_height"
            android:background="?attr/colorPrimary"
            app:tabGravity="fill"/>

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

Answer 6

To fix Bottom bar, firstly you have to use a Activity where tabs present. In that activity use different fragments. Add your tabLayout in this activity_main_tab.xml

activity_main_tab.xml

 <?xml version="1.0" encoding="utf-8"?>
    <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        xmlns:local="http://schemas.android.com/apk/res-auto"
        android:id="@+id/co_activity_root_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true">

            <android.support.design.widget.AppBarLayout
                local:theme="@style/Theme.AppBarOverlay"
                android:id="@+id/toolbar_layout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentTop="true">

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

            <RelativeLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_below="@+id/toolbar_layout">

                <FrameLayout
                    android:id="@+id/fl_fragment_container"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                   />
            </RelativeLayout>
        </RelativeLayout>

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

For fragment view use

fragment_tab.xml

here use app:layout_scrollFlags="scroll|enterAlways" in toolbar to make it scrollable

 <?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:id="@+id/coordinator"
        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/ThemeOverlay.AppCompat.Dark">

            <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"/>

            <android.support.design.widget.TabLayout
                android:id="@+id/tablayout"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:tabIndicatorColor="@color/white"
                app:tabIndicatorHeight="@dimen/profile_tablayout_indicator_height"
                android:background="?attr/colorPrimary"
                app:tabGravity="fill"/>

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

        <android.support.v4.view.ViewPager
            android:id="@+id/viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
