android - ExpandableListView 扩展到其他布局

Question

我有这样的布局:

<?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">

    <LinearLayout android:id="@+id/details" android:layout_width="match_parent"
        android:layout_height="wrap_content" android:orientation="vertical"
        android:gravity="center"
        android:weightSum="1"
        android:visibility="visible">

        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/background" >

            <TextView
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:text="Header text"
                android:id="@+id/textView6"
                android:background="@color/background"
                android:textColor="@color/textColor"
                android:padding="8dp" />
        </LinearLayout>

        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="8dp"
            android:layout_marginBottom="8dp"
            android:background="@color/headerBackground"
            android:padding="8dp">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceMedium"
                android:id="@+id/textView7"
                android:textStyle="bold" />
        </LinearLayout>

        <ExpandableListView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/listview_items"
            android:divider="@null"
            android:dividerHeight="0dp"
            android:groupIndicator="@null"/>
    </LinearLayout>

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:gravity="center|bottom">

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Back"
            android:id="@+id/buttonBack"
            android:layout_weight="1"
            android:clickable="true" />

        <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Next"
            android:id="@+id/buttonNext"
            android:layout_weight="1"
            android:clickable="true" />
    </LinearLayout>

</RelativeLayout>

当可扩展 ListView 包含一长串项目时，它会在底部布局(按钮布局)上展开。

有没有办法告诉 ListView 扩展到底部布局开始的地方？

我对您的 XML 文件做了一些更改。我所做的是制作您的按钮布局 android:layout_alignParentBottom="true" 并将您的详细信息布局设为 android:layout_above="@ +id/button_layout"。希望它能解决您的问题。
