shape

I have class MyView that extends View class. MyView should draw filled triangle. I drew a triangle but I cannot get it filled. This is my onDraw() method: @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); Paint paint = new Paint(); paint.setColor(android.graphics.Color.BLACK); canvas.drawPaint(paint); paint.setStrokeWidth(4); paint.setColor(android.graphics.Color.RED); paint.setStyle(Paint.Style.FILL_AND_STROKE); paint.setAntiAlias(true); Point a = new Point(0, 0); Point b = new Point(0, 100); Point c = new Point(87, 50); Path path = new Path(); path.setFillType(FillType

I want to set the background of a Relative or LinearLayout to a custom drawable. I want the shape to draw two horizontal lines across the bottom, leaving the central part transparent (empty). The following draws the horizontal lines centered vertically, where as i need them to be aligned to the bottom of the shape. (If you add a rectangle as an item you can see the shape expands to the dimenstions of the parent, but the lines are still centrally aligned). <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item> <shape android:shape=

I need to change the stroke color from the app. The user is able to change the background color so I need to also let them change the stroke (outline) of the button. As its is already set in the drawable (sample below) I have not found a way to change this. Seems like all of the other questions like this just said to use the XML file.... but that doesnt let me make it dynamic. Thank you for any help! I need to change the stroke color to a user defined color. Nothing to do with the state. <?xml version="1.0" encoding="UTF-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android">

I am trying to convert a System.Windows.Shapes.Shape object into a System.Windows.Media.Geometry object. With the Geometry object, I am going to render it multiple times with a custom graph control depending on a set of data points. This requires that each instance of the Geometry object has a unique TranslateTransform object. Now, I am approaching the issue in two different ways, but neither seems to be working correctly. My custom control uses the following code in order to draw the geometry: //Create an instance of the geometry the shape uses. Geometry geo = DataPointShape.RenderedGeometry

My question is simple, the solution surely not. I am looking for a way to shape a JFrame the same as an Image it will be displaying. By shape I mean the shape of the pixels that have an alpha != 0. I've already found a working example using a GeneralPath object, but it created ~110000 "nodes" for an Image of about 500*400, so starting the JFrame took more than 2 minutes, which is definitely not the desired effect, the startup should be in under 2 seconds. Thanks for your time. I personally would ditch the window shape in favor of a transparent window, it's just simpler for what you are trying

Given a point's coordinates, how can I determine if it is within an arbitrary shape? The shape is defined by an array of points, I do not know where the shape is 'closed', the part I really need help is to work out where the shape is closed. Here's an image to illustrate what I mean a little better: Easiest way to do it is cast a ray from that point and count how many times it crosses the boundary. If it is odd, the point is inside, even the point is outside. Wiki: http://en.wikipedia.org/wiki/Point_in_polygon Note that this only works for manifold shapes. If you want to determine whether or

This question already has an answer here: How to define a circle shape in an Android xml drawable file? 14 answers How would I achieve a round shape in Android, like below, through an Android shape drawable: You need to create a shape drawable in the drawable folder that looks something like: <?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval" > <gradient android:startColor="#FFFF0000" android:endColor="#80FF00FF" android:angle="270"/> </shape> (For this example I have saved the drawable as circle.xml and it will have a
