Error parsing XML: not well-formed (invalid token) andElement type “LinearLayout” must be followed by either attribute specifications, “>” or “/>” [closed]

Answer 1

These Views here

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

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

need to be closed. Every View needs to be closed at some point with />. The LinearLayout is a root View so it is being closed at the end with

</LinearLayout>

so it just needs a > at the top

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

The EditText is ready to be closed since you are done adding properties to it so add />

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

Answer 2

You haven't closed off your XML tags properly. Additionally, you need to have your string resources in a separate file in the /res/values/ folder. Try using:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="horizontal" >
<EditText android:id="@+id/editmessage"
    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_conent"
    android:text="@string/button_send"/>

</LinearLayout>

And put the following in a new file under /res/values:

<?xml version"1.0" encoding="utf-8"?>

<rescources>
    <string android:name="app_name">becreativebuddy</string>
    <string android:name="edit_message">Enter a message</string>
    <string android:name="button_send">Send</string>
    <string android:name="action_settings">Settings</string>
    <string android:name="title_activity_main">MainActivity</string>
</rescources>
