fixed by changing it to val end = layout.getLineEnd(layout.lineCount - 1)

I have the TextView maxLine set to 5 and when I call getLineEnd(4) on a view that most definitely has 5+ lines it gives me the ArrayIndexOutOfBoundsException. I can’t figure out why this is happening. please help? Thanks!

fun TextView.visibleText(): String {
    val end = layout.getLineEnd(4)
    return layout.text.toString().substring(0,end);
}

<TextView

Here’s a picture of the view. The detailed review block is the textview in question
