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.

textView.getLayout is the way to go but the problem with that is that it returns null if layout is not prepared. Use the below solution.

 ViewTreeObserver vto = textview.getViewTreeObserver();
    vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
           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");
           }  
        }
    });

Code snippet for removing the listener (source):

mLayout.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
    public void onGlobalLayout() {
        scrollToGridPos(getCenterPoint(), false);
        mLayout.getViewTreeObserver().removeOnGlobalLayoutListener(this);        
    }
});

I think the easiest solution to this question is the following code:

String text = "some looooong text";
textView.setText(text);
boolean isEllipsize = !((textView.getLayout().getText().toString()).equalsIgnoreCase(text));

This code assumes that in your XML the TextView set a maxLineCount :)

This worked to me:

textView.post(new Runnable() {
                        @Override
                        public void run() {
                            if (textView.getLineCount() > 1) {
                                //do something
                            }
                        }
                    });
