How to get line count of textview before rendering?

Question

How can I get the number of lines a string will take up in a TextView before it is rendered.

A ViewTreeObserver will not work because thos

Answer 1

final Rect bounds = new Rect();
final Paint paint = new Paint();
paint.setTextSize(currentTextSize);
paint.getTextBounds(testString, 0, testString.length(), bounds);

Now divide the width of text with the width of your TextView to get the total number of lines.

final int numLines = (int) Math.ceil((float) bounds.width() / currentSize);

currentSize : Expected size of the view in which the text will be rendered. The size should not go beyond the screen width.
