Answer 1

Take out bottom button from the nestedscrollview and take linearlayout as parent. Add bottom and nestedscrollview as thier children. It will work absolutely fine. In manifest for the activity use this - this will raise the button when the keyboard is opened

android:windowSoftInputMode="adjustResize|stateVisible"

<?xml version="1.0" encoding="utf-8"?>

Please use below solution it has taken my lots of time to fix.

Enjoy your time :)

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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/white"
    >

    <ScrollView
        android:id="@+id/mainScroll"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/white"
        android:fillViewport="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentStart="true">
        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">


            <android.support.constraint.ConstraintLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="bottom"
                android:layout_alignParentStart="true"
                android:layout_alignParentTop="true"
                android:layout_alignParentBottom="true"
                android:layout_alignParentEnd="true"
                >

            </android.support.constraint.ConstraintLayout>

        </RelativeLayout>
    </ScrollView>
</RelativeLayout>

Answer 3

Answer 4

A lot of answers here, nothing really simple. It's important that the ScrollView's lauout_height is set to match_parent while the layout_height of the ContraintLayout is wrap_content

<ScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
    
    ...

Answer 5

For completing the previous answers I am adding the following example, which also takes into account the use of the AppBar. With this code, the Android Studio design editor seems to work fine with the ConstraintLayout.

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout
    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:background="@drawable/bg"
    android:orientation="vertical">

<android.support.design.widget.AppBarLayout
    android:id="@+id/app_bar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.ActionBar.AppOverlayTheme">
    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        app:popupTheme="@style/AppTheme.PopupOverlay"/>
</android.support.design.widget.AppBarLayout>

<ScrollView
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <ImageView

        <Button

            android:padding="8dp"
            android:text="@string/intro_button_return"
            android:textStyle="bold"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/button_recycle" />

        <Button
            android:id="@+id/button_recycle"
