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滚动视图添加文本。我在安卓工作室工作。我有一个正在读取的文件，并已将文本行放入StringBuilder缓冲区对象中

现在如何在滚动视图中显示文本？我需要使用吗。AddView

Answer 1

Scrollview是一个单元素容器，这意味着其中应该只有一个元素

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.

所以你应该在你的ScrollView中添加一个LinearLayout，然后添加视图

Answer 2

在ScrollView中添加TexView：

TextView tv = new TextView(this);
tv.setText("Your string");

scrollView.addView(tv);
