我正在设计一个应用程序,其中包含列表项的xml文件(list_item.xml),以及listView(NewsAdapter.java)的适配器.

我的应用在运行时遇到此错误:

我在项目中使用了BottomSheetDialogFragment，并且设计如下：

目标：在两种模式下，我都将BottomSheetDialog的底部菜单粘贴到屏幕底部，然后展开。

因此，在BottomSheetDialog布局中，我将RelativeLayout用作父对象，将“ layout_alignParentBottom”用作菜单容器，如下所示：

<RelativeLayout 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:id="@+id/bottomSheetContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
app:behavior_hideable="true"
app:behavior_peekHeight="0dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
tools:context=".MyBottomSheetDialogFragment">

<RelativeLayout
    android:id="@+id/topSection"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true">
    ....
</RelativeLayout>

<android.support.v4.widget.NestedScrollView
    android:id="@+id/descriptionContainer"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/topSection">
    ....
</android.support.v4.widget.NestedScrollView>

<HorizontalScrollView
    android:id="@+id/iconsContainer"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true">
    ....
</HorizontalScrollView>
</RelativeLayout>

但是对话如下：

如您所见，底部菜单一开始不可见。

有人可以帮我解决这个问题吗？
