How to Tell If My Textview Has Been Ellipsized

How do I tell if my textview has been ellipsized?

You can get the layout of the TextView and check the ellipsis count per line. For an end ellipsis, it is sufficient to check the last line, like this:

Layout l = textview.getLayout();
if (l != null) {
    int lines = l.getLineCount();
    if (lines > 0)
        if (l.getEllipsisCount(lines-1) > 0)
            Log.d(TAG, "Text is ellipsized");
}

This only works after the layout phase, otherwise the returned layout will be null, so call this at an appropriate place in your code.

Check if textview is ellipsized in android

You can use this method provided: getEllipsisCount

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");
        } 
    } 
}

where line could be obtained via getLineCount()

How to tell if TextView text has been truncated due to singleLine=true?

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");
        } 
    } 
}

How to identify if a text was ellipsized or not

You can check

Layout layout = textview.getLayout();
if (layout != null) {
    int lines = layout.getLineCount();
    if (lines > 0) {
        if (layout.getEllipsisCount(lines-1) > 0) {
            return true;
        } else
            return false;
    }
}
