Question

Im having a white space issue in my Recyclerview inside Scrolling activity. Please help me to resolve this problem. i have checked everything i have known such as no margins,paddings,tried by removing the FAB. but still the problem exists.

My XML 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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
   >

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

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/toolbar_layout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/AppTheme.PopupOverlay" />

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/id_recyclerview"
        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_marginRight="@dimen/fab_margin"
        android:src="@android:drawable/ic_dialog_email"
        app:layout_anchor="@id/app_bar"
        app:layout_anchorGravity="bottom|end" />

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

For me it looks like your height from AppBarLayout is bigger than the content and white space appears. Replace it with wrap content — mhenryk, Aug 29 '16 at 13:33
@mhenryk: when i use wrap_content as layout height , the whole appbar disappears. — Mr Robot, Aug 29 '16 at 14:04
Right, make sure your layout has the proper height. To me it looks like it misses a statusbar size. Check what happens if you remove "fitsSystemWindows" from CoordinatorLayout. Keep it in AppBar though. — mhenryk, Aug 29 '16 at 14:05
The code you have mentioned seems alright. Need to check the RecyclerView's list item layout. — Chintan Soni, Aug 29 '16 at 14:18
@ChintanSoni: if item layout had any problems, i guess the whitespace should come between every Recycler view item. So its not the problem of item Layout — Mr Robot, Aug 29 '16 at 14:55
This problem is happening between the appbar and the recycler, doesnt seem to have anything to do with the wxh of them — TWL, Aug 29 '16 at 15:01
Last thing to check is the theme you're using and support library version. Please check and revert back with comment. — Chintan Soni, Aug 29 '16 at 15:51

Try this by removing android:fitsSystemWindows="true" and android:layout_height="wrap_content"

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

if i put `android:layout_height="wrap_content"` the appbar will disappear. – Mr Robot Aug 31 '16 at 09:24

Atlast i figured it now, First of all,Thanks to TWL for giving me an idea by a same issue of his question .

I removed the android:fitsSystemWindows="true" from the CoordinatorLayout.

Now, your notification bar's color is probably change to Transparent and looks horrible. So, i have added <item name="android:statusBarColor" tools:targetApi="lollipop">@color/colorPrimary</item> in styles.

Now everything is Okay.

thank you, but if you notice now, your notification bar's color is probably not part of your app's theme color because it's no longer 'under', but 'below' it now. – TWL Aug 30 '16 at 17:16
@TWL : yes, i changed that too by adding `@color/colorPrimary` in styles – Mr Robot Aug 31 '16 at 07:40
