How to find character position on canvas in android?

Question

Java

There is a canvas with multiline text. How, when you click on the screen, determine the square in which the character that was clicked will be inscribed? Or multiple squares if the press captures multiple characters.

Answer 1

To make it fast, when displaying text in the canvas, you will have to remember somewhere else the bounding-boxes for your characters, and then look not for the canvas, but for the data structure with the bounding boxes.
