Hi, I guess now i have understood my issue and can explain it much better and clearly.
I am loading all my view dynamically in a Horizontal ViewGroup. Inside one view there a collection of pictures along with text and the bottom. I have the width and height of the view fixed (When creating a view i pass the width and height to the layout params). The image is loaded dynamically, till then a loading icon is display. But the text is already display in the TextView. The visible lineCount that I get before the image is different than the lineCount that I actually displayed after the Image is loaded. I want to revalidate the whole view again after the image loading and displayed in the UI. I tried sevaral methods to revalidate the TextView, the Layouts, but none of it help me to get the correct visible line count after image is loaded. -Ankur.
