Android Build a Simple Android App Creating the Screen Layout Adding a Button

what did i do wrong?

every time i run the program all the buttons shift to the top left corner. No i didn't set them there it just does it.

activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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"
    tools:context="com.example.slohr5891.androidassignment1.FunFacts">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:lineSpacingExtra="8sp"
        android:text="Did you know..."
        android:textSize="24sp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintHorizontal_bias="0.111"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintVertical_bias="0.058" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/factTextView"
        android:lineSpacingExtra="8sp"
        android:text="ants stretch when they wake up in the morning?"
        android:textSize="24sp"
        tools:layout_editor_absoluteX="25dp"
        tools:layout_editor_absoluteY="88dp" />

    <Button
        android:id="@+id/showFactButton"
        android:layout_width="368dp"
        android:layout_height="wrap_content"
        android:text="Show another fun fact"

        tools:layout_editor_absoluteX="16dp"
        tools:layout_editor_absoluteY="410dp" />

</android.support.constraint.ConstraintLayout>

It looks like the challenge you posted this again is wanting you to copy and paste the TextView element and change 'TextView' to 'Button' - resulting in:

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

  <TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

  <Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

</RelativeLayout>
