RecyclerView is cutting off the last item

I have a fragment with a toolbar and a recyclerView inside it.

I am populating the recyclerView with dummy data and then try to show them. For some reason, the last element of the recyclerView is getting cut-off.

This is the XML of the fragment:

<?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:background="@color/background_1"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar_layout"
        android:layout_width="match_parent"
        android:layout_height="@dimen/height_of_app_bar"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

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

            <ImageView
                android:id="@+id/backdrop"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                android:src="@drawable/placeholder_rect_header"
                app:layout_collapseMode="parallax"/>

            <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/ThemeOverlay.AppCompat.Light"/>

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

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/simpleList"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

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

The items at the list are really simple ones:

<?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="200dp"
    android:background="@color/background_1"
    android:orientation="horizontal"
    android:padding="@dimen/space_for_a_bit_of_air">

    <ImageView
        android:id="@+id/album_cover"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_gravity="center_vertical"
        android:scaleType="fitXY"
        android:src="@drawable/placeholder_album_cover"/>

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_marginLeft="@dimen/space_for_distinguishing_stuff"
        android:orientation="vertical">

        <TextView
            android:id="@+id/album_title"
            style="@style/titleText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/sample_text_c"/>

        <TextView
            android:id="@+id/album_year"
            style="@style/subtitleText"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/sample_text_a"/>

    </LinearLayout>

</LinearLayout>

I am now at the end of the list, but the last element still looks cut-off.

I am using the latest version as of 2015-09-23 of google libraries, 23.0.1, (i.e. com.android.support:recyclerview-v7:23.0.1), and the following configuration at the build.gradle:

compileSdkVersion 23
buildToolsVersion "23.0.1"

defaultConfig {
   minSdkVersion 14
   targetSdkVersion 23
   versionCode 1
   versionName "1.0"

   multiDexEnabled true// Enabling multidex support
 }

Any help would be greatly appreciated since I am going nuts with this problem :(

SOLUTION

Ok, after cleaning the code to the bare essentials and removing complexity, I found the problem: it was a combination of wrong flags and missing or extra attributes. The following works fine for both Android 4.x and 5.x:

<?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:background="@color/background_1"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar_layout"
        android:layout_width="match_parent"
        android:layout_height="@dimen/height_of_app_bar"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:collapsedTitleTextAppearance="@style/Title.collapsed"
            app:contentScrim="@color/primary"
            app:expandedTitleMarginStart="48dp"
            app:expandedTitleTextAppearance="@style/Title.Expanded"
            app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed">

            <ImageView
                android:id="@+id/backdrop"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                android:src="@drawable/artistic_4"
                app:layout_collapseMode="parallax"/>

            <View
                android:layout_width="match_parent"
                android:layout_height="@dimen/height_of_app_bar"
                android:background="@drawable/gradient"/>

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

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

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

    <android.support.v7.widget.RecyclerView
        android:id="@+id/simpleList"
        style="@style/genericRecyclerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:listitem="@layout/item_discography_album"/>

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

In a nutshell, android:fitsSystemWindows="true" should only be at the coordinatorLayout, AppBarLayout and theCollapsingToolbarLayout (which are the ones that we want to be adjusted based on the screen on Android 5.x), the app:layout_scrollFlags should be set to "scroll|enterAlways|enterAlwaysCollapsed" and the toolbar should have as height, the height of the actionBar. Finally, it's better to keep the RecyclerView as clean as possible so you can control the layout spacing at each line item.

Solution 1:

Try to change your RecyclerView height to "wrap_content" and add the AppBarLayout height as margin bottom.

<android.support.v7.widget.RecyclerView
        android:id="@+id/simpleList"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="@dimen/height_of_app_bar"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

The cut-off part of the list item, is the height of the AppBarLayout.

Solution 2:

I tried all the available option from most of possible site but I didn't get the solution. Then, I think can I use bottom padding? And Yes, It's work for me.

I am sharing the code to you. Nothing more attribute required other than height, width & padding.

android:paddingBottom="?attr/actionBarSize"

 <android.support.v7.widget.RecyclerView
    android:id="@+id/your id name"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="?attr/actionBarSize"
    app:layout_constraintTop_toBottomOf="@+id/your field" />

Solution 3:

If you are using Constraint Layout, make sure the layout_height is 0dp and layout_constraintBottom_toBottomOf constraint is set properly.

  <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/recyclerView"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/titleTextView"
     />

Solution 4:

This worked for me. Set both height and width of the recyclerView to 0dp

 <android.support.v7.widget.RecyclerView
    android:id="@+id/rv_materias"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:layout_marginTop="20dp"
    android:background="@color/secondaryLightColor"
    app:layout_constraintBottom_toTopOf="@id/bottom_navigation"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@id/guideline6"></android.support.v7.widget.RecyclerView>
