Relative布局出错?谁能帮我改一下

Question

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
             android:layout_height="fill_parent">
   <TextView  
    android:id="@+id/text1"
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"
    android:text="hello1"
    android:layout_alignParentTop="true" android:layout_width="match_parent"/>
       <TextView
     
    android:id="@+id/text2"
    android:text="hello2"
   
    android:layout_below="@id/text1"
    android:layout_alignParentTop="true"
    android:layout_height="fill_parent"
    android:layout_width="fill_parent"
    />
   </RelativeLayout>结果 hello1,与hello2重合了，android:layout_below="@id/text1"没起作用啊？
为什么？

Answer 1

两个都有android:layout_alignParentTop="true"

Answer 2
