Android Canvas.drawText

Question

Hi All,

I have a view, I'm drawing with the Canvas object in the onDraw(Canvas canvas) method. My code is:

Paint paint = new Paint();
paint.setColor(Color.WHITE);
paint.setStyle(Style.FILL);
canvas.drawPaint(paint);

paint.setColor(android.R.color.black);
paint.setTextSize(20);
canvas.drawText("Some Text", 10, 25, paint);

The problem is the text doesn't show through the background, what am I doing wrong? If I remove the canvas.drawPaint(paint) and paint.setColor(android.R.color.black) you can see the text on the screen.....

Answer 1

Judging by the code, it looks like since you're using the same instance of Paint for the background and the text color, they're essentially being painted with the same brush. Instantiate two different Paint objects and use them separately and see if that fixes it.

Answer 2

Hi All,

Worked this out, turns out that android.R.color.black is not the same as Color.BLACK. Changed the code to:

Paint paint = new Paint(); 
paint.setColor(Color.WHITE); 
paint.setStyle(Style.FILL); 
canvas.drawPaint(paint); 

paint.setColor(Color.BLACK); 
paint.setTextSize(20); 
canvas.drawText("Some Text", 10, 25, paint); 

and it all works fine now!!
