Thanks for replying again. * * * you can override its height in the getview() and set it at 1 dp high (tip: don't set the row view to View.GONE). At the end of the animations you will just be fiddling around with row heights and view contents so you shouldn't need the notifyDatasetChanged().* * * I could not get you by setting it at 1 dp high.And what i need to do after animation ends?Please explain little more.
