如何在Android中的Relativelayout内部放置一个Linearlayout

SAN*_*HYA 2 android relativelayout android-layout android-linearlayout

我需要在relativelayout的底部放置一个线性布局,这是xml中最顶层的父布局.我怎样才能做到这一点?

请帮我.

 <?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"
android:background="@drawable/background"
android:orientation="vertical" >
<RelativeLayout .......   <<--- this should occupy total available space
</Relativelayout
 <Linearlayout .......     <<-- this should place at bottom always with height 50dp
 </LineaLayout>
 </ReltiveLayout>

请试试这个:

<LinearLayout android:layout_alignParentBottom="true" android:layout_height="50dp" android:layout_width="wrap_content">
</LinearLayout>

你可以在xml的底部与上面的属性对齐.
