我正在以编程方式在TableLayouts中创建一些ScrollView，并且可以通过动态添加/删除一些TableLayout来更改这些TableRows的内容。
问题是，除了最后一个没有明显原因的奇怪行为之外，其他所有东西都正常运行。
当我在“问题”上方的TableRows中添加/删除一些TableLayouts时，其中的一些单元格突然在列中显示内容，每列一个字符，然后熄灭单元格而没有拉伸单元格，那是使内容不可读的原因。
我不知道为什么会这样，因为这是唯一一个发生此问题的人。
我认为该问题可能与以下事实有关：ScrollView在调整其内容时会自动调整大小，而“有问题的” TableLayout在ScrollView的末尾这会引起一些意想不到的变化。
我应该如何解决这个问题？
