Answer 1

Change this EditText

android.support.v7.widget.AppCompatEditText

to this

android.support.design.widget.TextInputEditText

Full Code :

<android.support.design.widget.TextInputLayout
       android:id="@+id/email_field"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:paddingBottom="16dp"
       android:hint="@string/email_phone"
       android:paddingTop="48dp">

    <android.support.design.widget.TextInputEditText
            android:id="@+id/et_email"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:inputType="textEmailAddress"
            android:paddingEnd="0dp"
            android:paddingStart="8dp"
        />
</android.support.design.widget.TextInputLayout>

Answer 2

Try not using

<android.support.v7.widget.AppCompatEditText

instead use

<EditText

So you will get:

<EditText
            android:id="@+id/et_email"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"
            android:inputType="textEmailAddress"
            android:paddingEnd="0dp"
            android:paddingStart="8dp" />

After doing a bit of research on the issue i found this post:

EditText added is not a TextInputEditText. Please switch to using that class instead

let me know if it helps you.
