KAdapter
KAdapter 是Kotlin版本RecyclerView Adapter的封装,使用DSL创建Adapter，使用更简洁的方式创建
Usage
当前最新版本 1.0.2
引库
implementation 'cn.ustory.qy:kadapter:1.0.2'
-
创建
-
最简单创建
var simpleAdapter: KotlinAdapter<Menu> = KAdapter(R.layout.menu_list) { bindData { type, vh, data -> vh.itemView.tv_title.text = data.name } }
-
或
var myAdapter: KotlinAdapter<Person> = KAdapter { layout { R.layout.list_item } bindData { vh, data -> vh.itemView.tv_text.text = data.name } }- 带数据创建
var myAdapter: KotlinAdapter<Person> = KAdapter {
layout {
R.layout.list_item
}
data {
arrayListOf(Person("张三"), Person("李四"))
}
bindData { vh, data ->
vh.itemView.tv_text.text = data.name
}
}
- 3. 带header footer创建
var myAdapter: KotlinAdapter<Person> = KAdapter {
layout {
R.layout.list_item
}
data {
arrayListOf(Person("张三"), Person("李四"))
}
bindData { vh, data ->
vh.itemView.tv_text.text = data.name
}
header(R.layout.header){
it.tv_text.text = "My name is Header"
}
footer(R.layout.footer){
it.tv_text.text = "My name is Footer"
}
}
- 4. 实现多类型布局(效果图如下)
<div align="center">
<img width=350" height="630" src="https://github.com/UCodeUStory/KAdapter/blob/master/demo_image.jpeg"/>
</div>
var mutilAdapter: KotlinAdapter<Menu> = KAdapterFactory.KAdapter {
multiLayout {
layout {
R.layout.red_layout
}
layout {
R.layout.yellow_layout
}
layout {
R.layout.blue_layout
}
layout {
R.layout.green_layout
}
}
bindData { type, vh, data ->
when (type) {
R.layout.red_layout -> vh.itemView.tv_item.text = data.name
R.layout.yellow_layout -> vh.itemView.tv_item.text = data.name
R.layout.blue_layout -> vh.itemView.tv_item.text = data.name
R.layout.green_layout -> vh.itemView.tv_item.text = data.name
}
}
}
- 使用
1. 直接使用
//设置点击事件
myAdapter.onItemClick { position, view -> Toast.makeText(this, "position=" + position, Toast.LENGTH_SHORT).show() }
myAdapter into recyclerView
2. 重新设置新值使用
myAdapter.data{
arrayListOf(Person("John"), Person("Bob"))
}
myAdapter.header(R.layout.header){
it.tv_text.text = "My name is Header"
}
myAdapter.footer(R.layout.footer){
it.tv_text.text = "My name is Footer"
}
myAdapter into recyclerView
3. 多类型使用
//原始数据
var datas = arrayListOf(Menu("Android"), Menu("IOS"), Menu("微信小程序"), Menu("HTML程序"))
mutilAdapter.data(datas) {
update(0,R.layout.red_layout) //设置第一个元素类型为red_layout
update(0..1,R.layout.yellow_layout) //设置0 到 1的类型为yellow_layout，如果之前设置过0，会覆盖之前的设置的类型
update(2,R.layout.blue_layout)
update(3,R.layout.green_layout)
insert(2,R.layout.red_layout,"Python")//在第2个位置后插入一个red_layout类型数据,
}
// 对新增red_layout类型数据单独设置，新数据使用backupData字段，因为新数据类型不确定
mutilAdapter.bindData(R.layout.red_layout){
type, vh, data, backupData ->
backupData?.let {
vh.itemView.tv_item.text = backupData as String
}
}
// 对原始旧数据重新设置，原始数据使用data字段
mutilAdapter.bindData(R.layout.green_layout){
type, vh, data, backupData ->
data?.let {
vh.itemView.tv_item.text = "新·"+data.name
}
}
mutilAdapter into recyclerView
