由 筅森魡賤 提交于 2019-11-26 15:53:54
问题 What I'm trying to achieve is to use a Drawable with a couple of layers inside it, but control some values at runtime such as the startColor for the gradient. Here's what I have in my_layered_shape.xml: <?xml version="1.0" encoding="utf-8"?> <layer-list xmlns:android="http://schemas.android.com/apk/res/android" > <item> <shape android:shape="rectangle"> <stroke android:width="1dp" android:color="#FF000000" /> <solid android:color="#FFFFFFFF" /> </shape> </item> <item android:top="1dp" android

Image/Graphic into a Shape

由 孤人 提交于 2019-11-26 14:41:32
I was wondering whether there is any way to convert an image/graphic into a Shape ? For example, can I convert the outline of a motorcycle shape into a Shape so I can then use it in Java? I know you can do it with normal squares or with rounded corners, polygons, etc. But is there a way to do a custom shape? motorcycle.jpg motorcycle-03.png ImageOutline.java This code requires some patience (when running). import java.awt.*; import java.awt.image.BufferedImage; import java.awt.geom.Area; import javax.imageio.ImageIO; import java.io.File; import java.util.Date; import javax.swing.*; /*

How to create a resizable rectangle with user touch events on Android?

由 ≡放荡痞女 提交于 2019-11-26 14:15:40
I want to create a rectangular shape that will be resized with the touches of the user. Below image is a good example of what i want to do: Is there any example like that? What do I need to study to implement this? Thanks in advance, To implement a custom view, you derive a class from View :) Override onDraw() for looks, override onTouchEvent() for input processing. Note that in Android, you cannot draw on view outside onDraw() ; if you want to refresh the view, call invalidate() . You can implement draggable corners as separate views. For looks, just use ready-made images (feel free to derive

How can I smooth my JFrame shape

由 折月煮酒 提交于 2019-11-26 09:57:40
问题 I gave my JFrame window a custom shape with rounded corners but how can I smooth it(anti-aliasing) 回答1: A lot will come down to how you are rendering your content, but the basic concept is to supply rendering hints to the Graphics context you are drawing to... For example, if I was painting to a component, I might use something like... // Create a "copy" of the graphics context so we don't modify any of it's existing // settings. This makes it easier to manage the graphics context as we //

How do I draw an arrowhead (in Android)?

由 假如想象 提交于 2019-11-26 09:45:15
问题 I\'m fairly new to Android and have been toying around with Canvas. I\'m attempting to draw an arrow but I\'m only having luck with drawing the shaft, none of the arrowhead is working. I have searched a bit and found a Java example, but Android doesn\'t have GeneralPath or AffineTransform . Right now my code looks like the following (the arrowhead looks nothing like an arrowhead): public class DrawableView extends View { Context mContext; private int centerX; private int centerY; private int
