Android canvas draw rectangle

how to draw empty rectangle with etc. borderWidth=3 and borderColor=black and part within rectangle don't have content or color. Which function in Canvas to use ``` void drawRect(float left, float top, float right, float bottom, Paint paint) void drawRect(RectF rect, Paint paint) void drawRect(Rect r, Paint paint) ``` Thanks. I try this example ``` Paint myPaint = new Paint(); myPaint.setColor(Color.rgb(0, 0, 0)); myPaint.setStrokeWidth(10); c.drawRect(100, 100, 200, 200, myPaint); ``` It draws rectangle and fill it with black color but I want just "frame" around like this image:
