I am getting error in LinearLayout tag while using linearlayout in constraintlayout

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.tourwip2.LoginActivity">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Login"

            />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Username: "
            />

        <EditText
            android:id="@+id/edtUsername"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            />

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Password: "
            />

        <EditText
            android:id="@+id/edtPassword"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="textPassword"
            />

        <Button
            android:id="@+id/btnLogin"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Login"
            />

    </LinearLayout>



</androidx.constraintlayout.widget.ConstraintLayout>

Is there any way to resolve that?
