1、效果爆照
2、代码实现
前提需要保证app有读写权限
activity_select_folder.xml文件如下
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"xmlns:app="http://schemas.android.com/apk/res-auto"android:background="@color/c1"><androidx.core.widget.NestedScrollViewandroid:layout_width="match_parent"android:layout_height="match_parent"
