Two rectangles next to eachother is not working (Java)

I am trying to draw a line, but I keep getting problems. I want to achieve something like this:

enter image description here

private Paint red = new Paint();
private Paint orange = new Paint();

red.setColor(Color.parseColor("#FF0000"));
orange.setColor(Color.parseColor("#FF8C00"));

canvas.drawRect(0, 400, 300, 0, red);
canvas.drawRect(300, 400, 300, 0, orange);

The orange bar just sits in the same spot as the red one... Why?

You have the top of 400 and the bottom of 0. It is strange. You might want to swap them. However, the problem is that your first line has a left bound of 0 and the right bound of 300, while the second line is an orange point, having the left bound of 300 and the right bound is exactly there, at 300.

Can you see that the length of the orange rectangle (300-300) is 0 in your code. That is why you can't see it. So try this:

    canvas.drawRect(0, 400, 300, 0, red);
    canvas.drawRect(300, 400, 600, 0, orange);

Take a look at the documentation again: Canvas.drawRect

drawRect(float left, float top, float right, float bottom, Paint paint)
Draw the specified Rect using the specified paint.

So your last two coordinate values (right and bottom) are NOT length but position.
