Rounded rectangles with rounded rectangles without inner rectangles

ellipse. When the width and height of the view are equal, the circle is drawn

Arcshape

Pathshape

Path PATH = new Path ();p ath.moveto (0);p ath.lineto (0, 50);p Ath.lineto (+),;p Ath.lineto (+),;p Ath.lineto, 0); Pathshape pathshape = new Pathshape (path, 200, 100); Shapedrawable drawable = new Shapedrawable (pathshape);d rawable.getpaint (). SetColor (color.red);d rawable.getpaint (). SetStyle (Paint.Style.FILL); imageview.setbackgrounddrawable (drawable);

Sets the shape to the Path object.

Pathshape constructor: Pathshape (Path, stdwidth, stdheight);

Stdwidth: Standard Width

Stdheight: Standard Height

When constructing a Pathshape object, a standard with a wide height is set. Intrinsic functions

protected void OnResize (float width, float height) {    Mscalex = width/mstdwidth;    Mscaley = Height/mstdheight;} public void Draw (canvas canvas, paint paint) {    canvas.save ();    Canvas.scale (Mscalex, Mscaley);    Canvas.drawpath (MPath, paint);    Canvas.restore ();}

There is a function resize () in the shape base class, where onresize () is called and resize () is called in shapedrawable.

With the standard width set, the ratio of the actual width to the standard width is calculated, and the canvas is scaled at the end of the drawing.

Effect: The (x, y) coordinate value in path is multiplied by the ratio value, which is the final rendered coordinate value (the actual interior is a scaled canvas)

For example, the w=400 of the view here, h=400

If the standard width is equal to 400, then the canvas is eventually not scaled, or 1:1.

Pathshape pathshape = new Pathshape (path, 400, 400);

stdx=400, stdy=400

Pathshape pathshape = new Pathshape (path, 100, 100);

stdx=100, stdy=100

Pathshape pathshape = new Pathshape (path, 200, 100);

stdx=200, stdy=100
