внутренняя рециркуляция

Question

У меня есть следующий XML макет -

У меня внутри этого держателя ConstraitLayout, который отключен для просмотра на определенном этапе в моем приложении.

Как вы можете видеть, как только я отключаю ConstraintLayout из поля зрения, внутренний RecyclerView обрезается пополам.

вот макет внутреннего RV -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@color/very_light_grey"
    android:orientation="horizontal">

    <TextView
        android:id="@+id/marketplace_cart_attribute_holder_attribute_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="@dimen/marketplace_14dp"
        android:textSize="16sp"
        tools:text="Attribute Name:" />

    <TextView
        android:id="@+id/marketplace_cart_attribute_holder_attribute_value"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginEnd="@dimen/marketplace_14dp"
        android:textSize="16sp"
        tools:text="Value" />

</LinearLayout>

Что я пропускаю - причины, по которым RV обрезают пополам, чего не происходит, когда виден нижний макет?

Answer 1

Добавьте нижнее поле -

android: layout_marginBottom = "15dp"

в свой LinearLayout, чтобы избежать проблемы для ряда экранов различных размеров:

<LinearLayout
            android:id="@+id/shopping_cart_holder_infobox_viewgroup"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_marginStart="7dp"
            android:layout_marginTop="15dp"
            android:layout_marginBottom="15dp"
            android:layout_marginEnd="0dp"
            android:orientation="vertical">

Answer 2

Решено - у меня есть избыточное поле marginTop в моей LinearLayout.
