膨胀的视图没有高度

Question

我正在我的应用程序中实现一个可扩展的recyclerview适配器，除了我的可扩展适配器中有一个gridview之外，一切都正常工作，在gridview我正在放置图像，但似乎可扩展适配器没有给出高度，当我预定义高度一切正常，但我不想预定义它，我希望它包装内容在这里是我的代码

我的适配器XML

<FrameLayout
style="@style/commonListItemStyle"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@drawable/bg_swipe_item_neutral">

<FrameLayout
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:clickable="true"
    android:foreground="?attr/selectableItemBackground">



<GridView
    android:id="@+id/expanded_grid"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    android:drawSelectorOnTop="true"
    android:background="#ecf0f1"
    android:numColumns="4"
    android:horizontalSpacing="3dp"
    android:verticalSpacing="3dp"
    android:listSelector="?android:attr/selectableItemBackground"

    />


</FrameLayout>

我的适配器代码

public class ExpandableCategoryAdapter extends ExpandableRecyclerAdapter<CategoryParentViewHolder, CategoryChildViewHolder> {
/**
