Try this:

if(yourTv.getLineCount() > 1) {
    yourTv.setTextSize();
else {
    yourTv.setTextSize();
}

You can use StaticLayout

    TextPaint textPaint = new TextPaint();
    textPaint.setTypeface(textView.getTypeface());
    textPaint.setTextSize(textView.getTextSize());
    textPaint.setTextAlign(Paint.Align.ALIGN_NORMAL);
    StaticLayout staticLayout = new StaticLayout(textString, textPaint, widthTextView, Layout.Alignment.ALIGN_NORMAL, 1f, 0f, true);
    if (1 == staticLayout.getLineCount()) {
        //do smth
    } else {
        //do smth else
    }
