相對佈局的問題

Question

我試圖放置兩個組件。第一個（Edittext）應該展開到下一個組件（一個提交按鈕）。我該怎麼做呢？我的XML如下... 的問題是，EDITTEXT擴展到填滿整個屏幕和隱藏的按鈕：

<?xml version="1.0" encoding="utf-8"?> 

<EditText 
      android:id="@+id/etFeedBackText" 
      android:hint="What do you think of this app? Any comments or suggestions?" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_alignParentTop="true" 
      android:layout_alignBottom="@id/btnFeedBackSubmit"    
      >  
</EditText> 

<Button 
    android:id="@+id/btnFeedBackSubmit" 
    android:text="Submit" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_below="@id/etFeedBackText" 
    android:layout_alignParentBottom="true" 
    > 

Answer 1

把按鈕聲明高於EditText，並在EditText屬性中設置： android:layout_above="@id/btnFeedBackSubmit"

Answer 2

刪除此行

android:layout_alignBottom="@id/btnFeedBackSubmit" 

Answer 3

試試這個

<EditText 
      android:id="@+id/etFeedBackText" 
      android:hint="What do you think of this app? Any comments or suggestions?" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_above="@id/btnFeedBackSubmit"    
      >  
</EditText> 

<Button 
    android:id="@+id/btnFeedBackSubmit" 
    android:text="Submit" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_alignParentBottom="true" 
    > 

Answer 4

<EditText 
      android:id="@+id/etFeedBackText" 
      android:hint="What do you think of this app? Any comments or suggestions?" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:layout_alignParentTop="true" 
    XXXXXXXX remove this  android:layout_alignBottom="@id/btnFeedBackSubmit" 
    XXXXXXXX write this  android:layout_above="@id/btnFeedBackSubmit"   
      >  
</EditText>
