Can't see the entire text with a nestedscrollview and cardview

Question

I use a coordinator layout, with a collapsing toolbar and a nestedscrollview. Putting Lorem Ipsum code, I can't see the end of the text, because I can scroll, but not until the end.

And when I put more text, I can scroll further, but still not until the end.

Here is my example :

The last line isn't the last in my code.

My xml :

<?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:fitsSystemWindows="true"
    tools:context="fr.djey.secretapp.MainActivity">

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

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapse_toolbar"

            android:layout_height="match_parent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginStart="48dp"
            app:expandedTitleMarginEnd="64dp">

            <ImageView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@drawable/image"
                android:fitsSystemWindows="true"
                app:layout_collapseMode="parallax"
                android:scaleType="centerCrop"/>

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

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

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

    <android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="fill_vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="16dp">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:padding="16dp">

                <TextView
                    android:id="@+id/description"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/lorem_ipsum"
                    android:textColor="@android:color/black"/>

            </LinearLayout>

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

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

    <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>

Maybe that's because of the emulator?

EDIT :

Reply for the Madhur answer : I've tested to put a frame instead of the nestedscrollview and replace with java this frame on navigationview item click. It replaces the frame here :

        android:layout_margin="@dimen/fab_margin"

by this fragment :

        </LinearLayout>

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

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

But as you can see, the nestedscrollview doesn't work doing like that :

Answer 1

Finally I've done like that :

putting the nestedscrollview in the main and a frame inside:

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_gravity="fill_vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto">

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

        </FrameLayout>

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

Like that I can see more text, but not until the end. So I put a margin in the cardview inside the fragment : android:layout_marginBottom="80dp"

Answer 2

use this in for eg main.xml layout

<android.support.v4.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="fill_vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="16dp">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:padding="16dp">

                <TextView
                    android:id="@+id/description"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/lorem_ipsum"
                    android:textColor="@android:color/black"/>

            </LinearLayout>

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

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

and atlast inlcude this in your xml

<include layout="@layout/main"/>
