How to know the size of a text when using Canvas.drawText()

Question

I'm using the Canvas.drawText() to write text on a custom view. I want to add a background 9-patch drawable behind the text, so I need to know the boundaries of the text drawn. The text is given by the user, so it's not a fixed size.

For now I'm using a monospace font and I managed to build a size which looks not so bad, but in the hand i'd rather use another font.

You can use public void getTextBounds(String text, int start, int end, Rect bounds) method of Paint to get a rectangle that encloses all your text. Take a look at getTextBounds.

Hope this helps!

You also may use measureText

mTextTimeColorPaint.measureText(timeText)

I think getTextBounds(String text, int start, int end, Rect bounds) can do it for you.

This method belongs to Paint class:
