將線性佈局對齊到底

我有一個佈局，我希望最後的LinearLayout在底部對齊。我試圖設置重力和android:layout_marginbottom=0dp，似乎沒有人將它對齊到底部。將線性佈局對齊到底

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

你必須使用android:layout_gravity要做到這一點，不android:gravity。

http://developer.android.com/reference/android/widget/FrameLayout.html

layout_gravity指定就該重力到母體，在視圖本身的內容的gravity控件的佈置。

工作就像一個魅力。非常感謝你。 – mornindew

You should take a relative layout as inner layout of linear layout. Like this example. I hope its useful for you. 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:background="@drawable/mainact" 
    android:weightSum="6" > 

    <LinearLayout 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_marginLeft="10dp" 
     android:layout_weight="1" 
     android:orientation="vertical" > 

     <RelativeLayout 
      android:layout_width="match_parent"
