How to delete a specific line in a canvas

Question

I am using code

myCanvas.drawColor(0, Mode.CLEAR);

I use it to delete a string if it is not in the exact position.

But he clears all the lines drawn in the canvas.

So how can I remove a specific row from it

Answer 1

First, clip the canvas before drawing: clipRect (int left, int top, int right, int bottom) You need to make a rectangular area 1px wide.

Secondly, drawColor will clear the cropped area. drawColor (0, Mode.CLEAR);
