I have TextView with width as wrap content. In this TextView I set text, but text is not of the same length every time. When text is very long I use single line true and ellipsize: end. But now I have a problem. I want to set Visibility of other layout but that depends on the length my text. If text is too long to fit in the screen I want to setVisible true, but when text is short and when I don't need ellipsize, I want to set visibility false. So I need to check status of my TextView. When its ellipsize I want to setVisible true, when its not setVisible false. How I can do that. This is what I got:

tvAle.post(new Runnable() {

        @Override
        public void run() {

            int lineCount    = tvAle.getLineCount();
            Paint paint =  new Paint();
            paint.setTextSize(tvAle.getTextSize());
            final float size = paint.measureText(tvAle.getText().toString());
            Log.v("a", ""+size+" "+tvAle.getWidth());
            if ((int)size > (tvAle.getWidth()+10)) {
                allergiesLayout.setVisibility(View.VISIBLE);
            }

            else
                allergiesLayout.setVisibility(View.GONE);

        }

but this solution doesn't work.

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()
