Question

在回收器视图中放大视图时出现错误。它适用于Oreo和Pie，但不适用于Nougat及其下方的设备。

这是我用来放大视图的代码。

View itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.listing_row_item, parent, false);

我的xml文件是

 <?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
    android:layout_height="wrap_content"

如果您使用的布局仅支持API级别25+，则应将其放在res/layout-v25文件夹中（如果不存在则创建文件夹），并且必须为API级别创建替代布局下方res/layout文件夹中的24。

Android将在API级别25+上自动使用layout-v25。

如何在API级别25及以下的Android中为视图充气？
