Android的LinearLayout XML错误

Question

I'm trying to fix this so badly but I couldn't find where I've gone wrong.

The message:

Element type "LinearLayout" must be followed by either attribute specifications, ">" or "/>".

Why do I get this? Any ideas?

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:weightSum="100"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"

    **<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_weight="70"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:background="#0000FF"
        android:padding="20dp"
        android:paddingBottom="10dp"
        android:gravity="center_horizontal">



    </LinearLayout>


</LinearLayout>

Answer 1

It's a pretty self-explanatory error message.

You didn't close your LinearLayout tag. Add a > after android:orientation="vertical" .

Answer 2

You missed a ">" at the end:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:weightSum="100"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

Answer 3

Your first LinearLayout tag isn't closed. Add a > to the end of it, like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:weightSum="100"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

                                   ^

Answer 4

Error clearly states that you missed the closing tag. Every Layout and its attribute needs to have their own opening and closing tag. Add

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_weight="70"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
/>

or

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_weight="70"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

</LinearLayout>
