推荐答案

这个问题是因为recyclerView有默认焦点.

This problem because of recyclerView has default focus.

解决方案

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:descendantFocusability="blocksDescendants"
    android:orientation="vertical">

将 android:descendantFocusability="blocksDescendants" 添加到 scrollView 的直接布局中

Add android:descendantFocusability="blocksDescendants" to your immediate layout of scrollView
