I created 3 ImageButtons that look find in my layout in Android Studio, but when the app is loaded onto my phone, the buttons are tiny.

```
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.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:id="@+id/linearLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <AutoCompleteTextView
        android:id="@+id/CountryList"
        android:completionThreshold="1"
        app:layout_constraintEnd_toStartOf="@id/clearCountryButton"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:hint="Country"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp"
        android:layout_marginTop="16dp"
        android:layout_marginBottom="4dp"
        android:layout_width="0dp"
        android:layout_height="wrap_content" />

    <ImageButton
        android:id="@+id/clearCountryButton"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginRight="16dp"
        app:layout_constraintBottom_toBottomOf="@id/CountryList"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintLeft_toRightOf="@id/CountryList"
        tools:src="@android:drawable/ic_input_delete" />

```

I left off the next two AutoCompleteTextView and ImageButton pairs for brevity.

Here is how it looks in Android Studio...

And here is how it looks on my phone...

I can't see what I am doing wrong. Anyone?
