Unable to Draw on Bitmap at 0,0

Question

Im trying to draw a text at the coordinate 0,0 on a Bitmap using the code

   canvas.drawText(text, 0, 0, paint);

but the text is drawn outside the image,the text only appears when i try some 20,25 values.Why is this? isnt this code supposed to draw text at 0,0 i had tried (0.0f,0.0f) no luck.

Answer 1

The Y coordinate is for the text baseline, not the top. If you want the text top to be at y=0, do something like

FontMetrics fm = paint.getFontMetrics();
canvas.drawText(text, 0 /*x*/, 0 /*y*/ -  fm.ascent, paint);
