在android中单击按钮后如何重绘linearlayout？

Question

我有一个linearlayout，当我单击一个按钮时，它会动态填充texviews，但是linearlayoutout的内容没有出现，我该如何重画它？

Answer 1

To force a view to draw, call invalidate(). (see: http://developer.android.com/reference/android/view/View.html )

Answer 2

If the textView is changes inside the on click listen event on the button then there is no need to call the invalidate. I suggest you to post the code so that it will give a more clear picture.
