Multiple root tags in Android Studio [duplicate]

Question

I am edit my fragment_main.xml in Android Studio, and I am getting this error:

Multiple Root Tags

The code block in question here is:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="match_parent">

</LinearLayout>
<EditText   <!--Error here in the bracket-->
android:id="@+id/edit_message"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="@string/edit_message" />
<Button    <!--Error here in the bracket-->
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button_send"/>

I am getting the errors in the brackets before EditText and before Button

Since in Android every xml file there must be only one root layout. Just add the EditText and Button inside the LinearLayout. Right code is shown below

<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <EditText  
        android:id="@+id/edit_message"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="@string/edit_message" />

    <Button    
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/button_send" />

</LinearLayout>
