Get number of visible characters in textview when ellipsize was applied

Question

I want to get the number of characters which are visible in TextView when we have applied android:ellipsize in TextView. Suppose i have "This is dummy top stories title with multiline, This is dummy top stories title with multiline." text and i have set "android:ellipsize="end" android:maxLines="2"" these properties in my Textview , so it will cut down some text and show the 3 dots. Now i want the nuumber of characters which are visible.

Please explain your problem briefly, you can post here its relevant screenshot too. So, I better understand — Fenil Patel, Dec 20 '17 at 06:19

In case of singleLine TextView:

stringLength - textView.length()

would give how much text is not shown or ellipsized away in device.

Same way in case of multiline TextView you can use:

Layout textViewLayout = textview.getLayout();

textViewLayout.getEllipsisCount(textViewLayout.getLineCount()-1)

As per Documentation at developer.android.com

getEllipsisCount(int line)

Returns the number of characters to be ellipsized away, or 0 if no ellipsis is to take place.

Note: getEllipsisCount must be used after textview is visible/drawn.

textview.getLayout(); it is returning null here. – Sonal Bharwani Dec 20 '17 at 07:44
`textViewLayout.getEllipsisCount(textViewLayout.getLineCount()-1)` is returning 0 when string value is too large like approx 8000-9000 characters. – Sonal Bharwani Dec 21 '17 at 10:33
