Làm cách nào để đặt đầu trang và chân trang cho bố cục tuyến tính trong android

Question

Ai có thể cho tôi biết cách đặt đầu trang và chân trang cố định cho bố cục tương đối và điểm trung tâm? Tôi muốn thêm cuộn và thêm mảng webview động khi tôi muốn cuộn điểm trung tâm chỉ có thể cuộn được trong android. Ai có thể đưa ra một ví dụ?

Tôi đã thử nhưng trung tâm một phần webview không xuất hiện đúng cách, có gì để thay đổi không?

mã XML của tôi là

<?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"> 

    <!-- HEADER --> 
    <include android:id="@+id/top_header" 
     android:layout_alignParentTop="true" layout="@layout/layout_header" /> 


    <!-- FOOTER --> 
    <LinearLayout android:id="@+id/bottom_menu" 
     android:layout_width="fill_parent" android:layout_height="wrap_content"   
     android:orientation="vertical" android:layout_alignParentBottom="true"> 
     <!-- menu bar --> 
     <include layout="@layout/layout_footer_menu" /> 
    </LinearLayout> 

    <!-- MAIN PART --> 
    <LinearLayout android:orientation="vertical" 
     android:layout_width="fill_parent" android:layout_height="fill_parent" 
     android:layout_below="@id/top_header" android:layout_above="@id/bottom_menu" 
     android:layout_weight="1" 
     android:id="@+id/sub_content_view" 
     android:paddingBottom="5sp" android:background="#EAEAEA"> 
    </LinearLayout> 
</RelativeLayout> 

Nó là tốt hơn để thiết lập để CHỦ PHẦN cả:

android: layout_below = "@ id/top_header" android: layout_above = "@ id/bottom_menu"

Trong nội dung trường hợp của bạn sẽ được dưới chân và thanh cuộn sẽ được hiển thị không chính xác.

Ngoài ra, bạn cần đặt chân trang trong mã ở trên nội dung - android muốn xem ID (@ id/bottom_menu) nếu nó không được xác định trước đó.
