how to redraw linearlayout after clicking on button in android?

I have a linearlayout that is filled with texviews dynamically when i click on a button , but the content of linearlayout doesn't appear, how开发者_运维知识库 can i redraw it ??

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

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.
