java - 如何在运行时向 ScrollView 添加文本？

Question

我想知道如何在运行时向 ScrollView 添加文本。我在 Android Studio 工作。我正在读取一个文件，并将文本行放入 StringBuilder 缓冲区对象中。

现在如何在 ScrollView 中显示文本？我需要使用.AddView吗？

Answer 1

Scrollview是一个单元素容器，这意味着其中只能有一个元素。

A ScrollView is a FrameLayout, meaning you should place one child in it containing the entire contents to scroll; this child may itself be a layout manager with a complex hierarchy of objects. A child that is often used is a LinearLayout in a vertical orientation, presenting a vertical array of top-level items that the user can scroll through.

因此，您应该在 ScrollView 中添加 LinearLayout 并向其添加 View 。
