我有这个相对布局，其中有一个滚动视图。但是当滚动视图中有更多文本时，它不会显示底部文本，它位于我的按钮后面。我怎样才能解决这个问题？

这是我所做的：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#00AEEC"
    android:orientation="vertical"
    android:weightSum="100" >

    <RelativeLayout
        android:id="@+id/details_header"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="clip_horizontal"
        android:background="#00AEEC"
        android:padding="20dp" >



        <ImageView
            android:id="@+id/imageView1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:src="@drawable/onlywithalcohol_heading_page2" />

    </RelativeLayout>

 <RelativeLayout

向包含 Button 的 LinearLayout 添加一个 id，例如：

android:id="@+id/bottomLayout"

在包含滚动视图的 RelativeLayout 中使用它：

android:layout_above="@+id/bottomLayout"

请注意，底部边距为 20dp，如果您不想要它，您可以使用 android:layout_marginLeft、android:layout_marginRight 和 android:layout_marginTop 来确保您在其他任何地方都有 20dp 边距。

将您的布​​局更改为 LinearLayout 它应该适合您，您可能需要使用

android:gravity="bottom"

对齐屏幕底部的按钮

你可能需要使用

android:layout_weight=""

如果需要的话。

这是一个可以放置在LinearLayout垂直方向内的块：

<ImageView
    android:id="@+id/imageView1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:src="@drawable/ic_launcher" />

<TextView
    android:id="@+id/details_country"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="20dp"
    android:text="USA"
    android:textAlignment="center"
    android:textAppearance="?android:attr/textAppearanceMedium" />

<TextView
    android:id="@+id/details_title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@id/details_country"
    android:layout_centerHorizontal="true"
    android:layout_marginBottom="20dp"
    android:gravity="center_horizontal"
    android:text="Fastest Time To Drink A Pint Of Soda Water, Consume A Bowl Of Macaroni And Cheese With Chopsticks, Eat And Read A Fortune Cookie And Take A Shot Of Peach Schnapps "
    android:textAlignment="center"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:textColor="#FFFF00" />

<ScrollView
    android:layout_width="fill_parent"
    android:layout_height="200dp"
    android:layout_alignParentBottom="true"
    android:layout_below="@id/details_title"
    android:layout_centerHorizontal="true" >

    <TextView
        android:id="@+id/details_description"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginBottom="20dp"
        android:gravity="center_horizontal"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:text="Sam Birdsong removed a cork from an empty bottle of wine using just a napkin in two minutes, 55.47 seconds.He stipulated beforehand that he had to begin with an unopened bottle, uncork it and pour out the wine, then shove the cork back inside the bottle and pull it out with a cloth napkin , and this wilk take for ever and ever out the wine, then shove the cork back inside the bottle and pull it out with a cloth napkin , and this wilk take for ever and ever out the wine, then shove the cork back inside the bottle and pull it out with a cloth napkin , and this wilk take for ever and ever out the wine, then shove the cork back inside the bottle and pull it out with a cloth napkin , and this wilk take for ever and ever "
        android:textAlignment="center"
        android:textAppearance="?android:attr/textAppearanceMedium" />
</ScrollView>

<Button
    android:id="@+id/details_back_btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_weight=""
    android:gravity="bottom"
    android:padding="10dp"
    android:text="back"
    android:textSize="18sp"
    android:textStyle="bold" />
