使用LinearLayout和ScrollView将文本保留在底部

Question

我正在尝试构建一个包含多个选项的菜单，并且在页面底部应该有一个文本。页面应滚动以防图标不合适。文本应距离底部约6 dp，距图标最小距离，以便在屏幕具有不同配置时不会叠加（见图）

到目前为止，我有这样的配置：

＆＃13;

＆＃13;

< ScrollView xmlns: android = "http://schemas.android.com/apk/res/android"
xmlns: app = "http://schemas.android.com/apk/res-auto"
xmlns: tools = "http://schemas.android.com/tools"
android: layout_width = "match_parent"
android: layout_height = "match_parent"
tools: context = ".MainMenu" >

  
  <RelativeLayout
android: layout_width = "match_parent"
android: layout_height = "match_parent"
android: layout_margin = "5dp"
android: gravity = "center_horizontal" >

  
  <LinearLayout
android: layout_width = "match_parent"
android: layout_height = "match_parent"
android: orientation = "vertical" >

   
  <LinearLayout
android: layout_width = "match_parent"
android: layout_height = "match_parent"
android: layout_marginTop = "20dp"
android: orientation = "horizontal" >
  /// More linear layouts

  <
  /LinearLayout> <
  /LinearLayout>

  <
  /RelativeLayout>
  <!--</android.support.constraint.ConstraintLayout>-->
  <
  /ScrollView>

＆＃13;

＆＃13;

＆＃13;

到目前为止，一切正常，但事实是我无法将文字粘在底部。它感觉依赖于上面的LinearLayout。我可以设置一个边距到最后一个布局（包含文本的那个），但数字是猜测，这不是我想要的。

任何人都可以帮我吗？谢谢!!

I think its better if you just put TextView' outside ofScrollView. Solution can be multiple. On simple one can be Using aRelativeLayout` .

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_above="@+id/txt"
        android:orientation="vertical">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">
            <!-- Your content goes here-->

        </LinearLayout>
    </ScrollView>

    <TextView
        android:id="@+id/txt"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_gravity="center_horizontal"
        android:gravity="center_horizontal"
        android:text="TextView"
        android:textSize="24sp" />

</RelativeLayout>
