My Code Review

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
（错误标志在这里，
Multiple annotations found at this line:
- This LinearLayout layout or its RelativeLayout parent is useless
- error: Error parsing XML: not well-formed (invalid token)
- Element type "RelativeLayout" must be followed by either attribute specifications, ">" 
or "/>".这个错误怎么回事？
）<LinearLayout

android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<EditText 
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/> 
<LinearLayout

android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="right">
<Button 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Yes"
/>
<Button 
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="No"
/>
</LinearLayout>
</LinearLayout>
</RelativeLayout>

把相对布局删掉
