Question

I am using the following code snippet to create a bitmap with text.

Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); 
paint.setStyle(Style.FILL);
paint.setColor(fontColor);
paint.setTextSize(fontSize);
canvas.drawText("My Text", x, y, paint);

Here’s the catch. How do I determine the size of the Bitmap to use in the canvas beforehand? For instance if I want a bitmap with “Hello World!” on it, I want to find the width and height of it even before I draw the text on the canvas.

You can tyr this:

Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); 

Rect bounds = new Rect();

paint.setStyle(Style.FILL);
paint.setColor(fontColor);
paint.setTextSize(fontSize);

paint.getTextBounds("My Text", 0, "My Text".length(), bounds);

int width = bounds.width();
int height = bounds.height();

canvas.drawText("My Text", x, y, paint);
