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.

Can someone please suggest me some faster was to achieve my requirement.
try this one:
/**
* Calculates the lines needed to show the text.
*
* @param paint
* the TextPaint from the TextView
* @param text
* the text for the calculation
* @param textAppearance
* text typeface, size, and style
* @param avail
* the available width
* @return the number of lines needed to show the text
*/
public static int neededLines(final TextPaint paint, final String text,
final TextAppearanceSpan textAppearance, final int avail) {
if (TextUtils.isEmpty(text)) {
return 0;
}
final TextPaint textPaint = new TextPaint();
textPaint.set(paint);
textPaint.setTextSize(textAppearance.getTextSize());
textPaint.setTypeface(Typeface.create(textAppearance.getFamily(),
textAppearance.getTextStyle()));
final StaticLayout layout = new StaticLayout(text, textPaint, avail,
Layout.Alignment.ALIGN_NORMAL, 1.0f, 0.0f, false);
final int lineCount = layout.getLineCount();
return lineCount;
}
