Answer 1

I really don't understand your question correctly but will share where you are going wrong. A scroll view can only hold one child but in your case, your HorizontalScrollView has two children one is LinearLayout and another one is TextView please insert both to one parent layout.

Answer 2

另一个ScrollView中的ScrollView不起作用，您应该将ScrollView放置为root，然后将LinearLayout放置为ScrollView的直接子级

Answer 3

如果您要先使用TextView，然后再使用ImageView，然后在LinearLayout中先使用TextView，并将方向设置为垂直 ，然后在TextView添加ImageView之后，则需要将它们都放入同一个LinearLayout中，因为ScrollView只能处理直接的单个子对象，这就是原因。
