My xml code is

        android:id="@+id/layout_username"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:layout_marginStart="20dp"
        android:layout_marginEnd="20dp"
        android:hint="@string/register_hint_name"
        android:labelFor="@+id/username_input_text"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox">

        <EditText
            android:id="@+id/username_input_text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPersonName"
            android:drawableStart="@drawable/ic_user"
            android:drawableLeft="@drawable/ic_user"
            android:drawablePadding="15dp"

My Activity code is

if (username_text.isEmpty() || email_text.isEmpty() || password_text.isEmpty() || con_password_text.isEmpty()) {

                    layout_username.setError("The field Username is required!");
                    username_input_text.requestFocus();
}

you will need to use TextInputEditText instead of the normal EditText

here's an example

<com.google.android.material.textfield.TextInputLayout
   style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:boxStrokeErrorColor="@android:color/red"
            app:errorIconDrawable="@drawable/icon"
            app:errorTextColor="@android:color/white">

            <com.google.android.material.textfield.TextInputEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="text" />

        </com.google.android.material.textfield.TextInputLayout>
