Force layout
Forcelayout is an Android library for visualizing data. You can drawing graph with spring-like attractive forces.
Demo
Usage
Usage in kotlin
1. Gradle
repositories {
jcenter()
}
dependencies {
compile 'jp.kai:forcelayout:1.0.9'
}
2. Definitions of nodes
val nodes = ArrayList <Pair<String,Int>>() nodes.add(Pair("nodeName1", R.drawable.example1)) nodes.add(Pair("nodeName2", R.drawable.example2)) nodes.add(Pair("nodeName3", R.drawable.example3))or
val nodes: Nodes = Nodes() nodes.add(NodePair("nodeName1", R.drawable.example1)) nodes.add(NodePair("nodeName2", R.drawable.example2)) nodes.add(NodePair("nodeName3", R.drawable.example3))If you don't use image. You can just write node name.
val nodes: Array<String> = arrayOf( "nodeName1", "nodeName2", "nodeName3")
3. Definitions of links
val links = Arrays.asList("nodeName1-nodeName2", "nodeName1-nodeName3")or
val links: Links = Links() links.add(LinkPair("nodeName1", "nodeName2")) links.add(LinkPair("nodeName1", "nodeName3"))4. Set node and link style (optional)
val forcelayout = Forcelayout(applicationContext) forcelayout.node()
.size(100)
.style(Color.argb(100,200,30,50)) forcelayout.link()
.style(Color.argb(60,50,30,200), 5.0f)5. Set nodes and links
You can set node's size and link-strength, and so on. Please use anko if you write in kotlin.
val forcelayout = Forcelayout(applicationContext)
forcelayout.with(this) .size(200) .distance(200) .gravity(0.04) .friction(0.04) .nodes(nodes) .links(links) .start()| Params | Description |
|---|---|
size | To set image width. |
distance | To set distance between each nodes. |
gravity | To set gravitation. |
friction | To set gravitation between pair of nodes. |
nodes | To set nodes that contain node name and image. |
links | To set pairs that contain node names. |
