How to tell if TextView text has been truncated due to singleLine=“true”?
Clash Royale CLAN TAG#URR8PPPHow to tell if TextView text has been truncated due to singleLine=“true”?
I have a TextView that I would like to know if it has been truncated due to singleLine="true" in the XML.
What are some ideas to achieve this without having to pass in the displayed text but to detect this with the TextView only?
It is a possible solution but could we detect if the TextView is truncated with just the TextView itself and not having to pass in the resulting text?

all you really need is to see the length of the text once it is ellipsize and compare it to the line of text. here is another link with a good method: stackoverflow.com/questions/15567235/…

The answer the OP was looking for was found in the following link:
Check if textview is ellipsized in android
The answer basically uses this method to compare the length of the text to the ellipse count to tell if has been truncated.
Layout layout = textview1.getLayout();
if(layout != null) {
int lines = layout.getLineCount();
if(lines > 0) {
int ellipsisCount = layout.getEllipsisCount(lines-1);
if ( ellipsisCount > 0) {
Log.d(TAG, "Text is ellipsized");
}
}
}
