Buttons not showing up in Android Studio

Making an app, and none of the buttons are showing up! Tried running on different phones. Googled around, and got nothing! Please help! If you need any more details, please let me know!

Snippet of code from activity with no buttons:

   <android.support.constraint.Guideline
    android:id="@+id/guideline"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    app:layout_constraintGuide_begin="20dp" />

<Button
    android:id="@+id/button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="55dp"
    android:layout_marginTop="157dp"
    android:text="Text2"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

<Button
    android:id="@+id/button2"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="244dp"
    android:layout_marginEnd="128dp"
    android:text="Text3"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent" />

<Button
    android:id="@+id/button3"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="145dp"
    android:layout_marginStart="45dp"
    android:text="Text4"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toStartOf="parent" />

<Button
    android:id="@+id/button4"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="89dp"
    android:layout_marginEnd="32dp"
    android:text="Text5"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent" />

<Button
    android:id="@+id/button5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginBottom="27dp"
    android:layout_marginEnd="80dp"
    android:text="Text1"
    app:layout_constraintBottom_toTopOf="@+id/button"
    app:layout_constraintEnd_toEndOf="parent" />

I just pasted your code directly into a new project and it works fine. Make sure that you're wrapping your components in another layout. Here is what I wrapped your XML with:

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="com.test.MainActivity">
<!-- The rest of your code goes here -->
</android.support.constraint.ConstraintLayout>

Here is what it looks like on my tablet: enter image description here

You're using android.support.constraint.Guideline, when you should be using android.support.constraint.ConstraintLayout.

Just change that and you should be good to go!
