I have a ConstraintLayout that contains 3 buttons horizontally. I want the 3 buttons to have a fixed width and be evenly distributed across the width of the layout.

Just set android:layout_width="wrap_content" to android:layout_width="0dp" in all the 3 buttons

To make 3 view equally distribute across the width just need to set constraint start/end of each view must define correct

Code

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

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 1"
        app:layout_constraintEnd_toStartOf="@+id/button2"
        app:layout_constraintStart_toStartOf="parent"
        />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 2"
        app:layout_constraintEnd_toStartOf="@+id/button3"
        app:layout_constraintStart_toEndOf="@+id/button1"
        />

    <Button
        android:id="@+id/button3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Button 3"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@+id/button2"
        />

</android.support.constraint.ConstraintLayout>

If you need 3 views full width, just need to change android:layout_width="wrap_content" to android:layout_width="0dp"

You can use guideline with the percentage tag please check below xml and replace with image or button anything you want 

<android.support.constraint.ConstraintLayout
    android:id="@+id/layoutMyProperty"
    android:layout_width="match_parent"
    android:layout_height="100dp"
    android:layout_marginTop="@dimen/margin12"
    android:visibility="visible"
   >
    <android.support.constraint.Guideline
        app:layout_constraintGuide_percent="0.33"
        android:id="@+id/Guideline1"
        android:orientation="vertical"
        android:layout_width="1dp"
        android:layout_height="0dp"/>
    <android.support.constraint.Guideline
        app:layout_constraintGuide_percent="0.66"
        android:id="@+id/Guideline2"
        android:orientation="vertical"
        android:layout_width="1dp"
        android:layout_height="0dp"/>


    <ImageView
        android:id="@+id/myPropertyImage1"
        android:layout_width="0dp"
        android:layout_height="@dimen/homeImageH"
        android:scaleType="centerCrop"
        android:visibility="visible"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintRight_toRightOf="@+id/Guideline1"
        app:layout_constraintEnd_toStartOf="@+id/Guideline1"
        tools:src="@drawable/placeholder" />

    <ImageView
        android:id="@+id/myPropertyImage2"
        android:layout_width="0dp"
        android:layout_height="@dimen/homeImageH"
        android:scaleType="centerCrop"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toRightOf="@+id/Guideline1"
        app:layout_constraintRight_toLeftOf="@+id/Guideline2"
        app:layout_constraintTop_toTopOf="parent"
        tools:src="@drawable/placeholder" />

    <ImageView

        android:scaleType="centerCrop"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintLeft_toRightOf="@+id/Guideline2"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toTopOf="parent"
