Question

I have a class and I set the bounds like so:

tattoo.setBounds(getWidth() / 2 - zoomController - x, getHeight() / 2 - zoomController - y, getWidth()/ 2 + zoomController - x, getHeight()/ 2 + zoomController - y);
tattoo.draw(c);

I want to be able to perform an action when the user clicks within these bounds. What is the easiest way to check if the click is within the bounds?

Answer 1

Use theRect that describes the drawable’s bounds and call the contains(int x, int y) method on it, passing in the x and y touch coordinates. For example:

Rect bounds = tattoo.getBounds();
int x = ...
int y = ...
boolean withinBounds = bounds.contains(x, y);

Alternatively, you could create your own (static) helper method; the math is really basic. 🙂
