android error message from main.xml

Question

I am following an android tutorial it tells me to add this code to the main.xml file

    <TextView 
    android:layout_width="fill_parent"
    android:layout_height=height="wrap_content"
    android:text="This is my first Android Application"/>
    <Button
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="And this is a clickable button!/>

the main.xml file contains this text, but when I add the above code to the bottom of the code below, it says "your code contains errors, please correct them and try again" What should I do?

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

   <TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello" />

    </LinearLayout>

Answer 1

This is wrong:

<TextView 
    android:layout_width="fill_parent"
    android:layout_height=height="wrap_content"

Change to:

<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"

Answer 2

There are many errors in that code.

First TextView, remove the duplicated "=height" in layout_height:

<TextView 
android:layout_width="fill_parent"
android:layout_height="wrap_content"        
android:text="This is my first Android Application"/>

On your button, you're not closing the quotes in android:text. See:

<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="And this is a clickable button!"/>

Finally, put all that before the closing tag of LinearLayout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >

<!-- put stuff here -->

<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/hello" />

<!-- or here -->

</LinearLayout>

Answer 3

You are missing a quotation mark:

android:text="And this is a clickable button!/>

fix:

android:text="And this is a clickable button!"/>
