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

回答1:

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>
