Today's problems,,, saved to the blog, the next encounter to find a blog on the line,,,,,,

Today, when making an Android UI nesting layout, the following occurs when entering and exiting the following code:
<linearlayout
Xmlns:android= "Http://schemas.android.com/apk/res/android"
Xmlns:tools= "Http://schemas.android.com/tools"
android:orientation= "Vertical"
Android:layout_width= "Match_parent"
android:layout_height= "Match_parent"
tools:context= "${relativepackage}.${activityclass}" >


<button
Android:layout_width= "Wrap_content"
android:layout_height= "Wrap_content"
android:text= "Beijing Magic Music Technology"/>
<linearlayout
"Xmlns:android=" Http://schemas.android.com/apk/res/android ""
android:orientation= "Vertical"
android:layout_height= "Wrap_content"
Android:layout_width= "Wrap_content" >
<imageview
android:src= "@drawable/ic_launcher"
android:layout_height= "Wrap_content"
Android:layout_width= "Wrap_content"/>
<imageview
android:src= "@drawable/ic_launcher"
android:layout_height= "Wrap_content"
Android:layout_width= "Wrap_content"/>
</LinearLayout>
<tablelayout
"Xmlns:android=" Http://schemas.android.com/apk/res/android ""
android:orientation= "Vertical"
android:layout_height= "Wrap_content"
Android:layout_width= "Wrap_content" >

</TableLayout>


</LinearLayout>
"" The thing marked in this parenthesis appears red underlined.
There are the following
Unexpected namespace prefix "xmlns" found for tag linearlayout
The error, my solution is


is a namespace declaration as long as in the XML appears once, multiple occurrences of the error, it seems that the previous request.
Only the first declaration is retained, and the subsequent direct deletion is OK.
