本文介绍了解决在Fragment中使用RecyclerView时，底部控件被遮挡的问题。通过在最外层添加NestedScrollView，确保所有子控件都能正确显示，避免了布局冲突。

1.

问题造成原因

在fragment里，线性布局里面有RecycView和最下面的一个LinearLayout，结果最下面的控件不显示

解决办法：

最外面加多一个

<androidx.core.widget.NestedScrollView

全部XML

<?xml version="1.0" encoding="utf-8"?>
<androidx.core.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".ui.fragment.BlankFragment3">
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        <androidx.recyclerview.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/rv_latest"/>
        <LinearLayout

            <Button
