打造万能的适配器，超级简单使用，省时省力。
Kotlin,Androidx
Step 1. Add the JitPack repository to your build file
Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}
Step 2. Add the dependency
dependencies {
implementation 'com.github.fingerth:commonadapterkt:1.0.1'
}
//val lv:ListView
//val list: ArrayList<String>
lv.adapter = object : CommonAdapter<String>(this, list,android.R.layout.simple_list_item_1) {
override fun convert(holder: Holder, position: Int, data: String) {
holder.setText(android.R.id.text1, data)
}
}
//val vp:ViewPager
//val list: ArrayList<String>
vp.adapter = object : CommonPagerAdapter<String>(this, list, R.layout.pager_item_view) {
override fun convert(holder: Holder, position: Int, data: String) {
holder.setText(R.id.tv, data)
holder.setText(R.id.tv2, position.toString())
}
}
> 要支持无限滑怎办，不要担心，用这个UnlimitedSlidePagerAdapter<T>
//val vp:ViewPager
//val list:ArrayList<String>
vp.adapter = object : UnlimitedSlidePagerAdapter<String>(this, list, R.layout.pager_item_view) {
override fun convert(holder: Holder, position: Int, data: String) {
holder.setText(R.id.tv, data)
holder.setText(R.id.tv2, position.toString())
}
}
vp.setCurrentItem(ad.getMidPosition(),false)
正常使用
//val rv:RecyclerView
//val list:ArrayList<String>
rv.layoutManager = GridLayoutManager(this, 2)
rv.adapter = object : CommonRecyclerAdapter<String>(this, list) {
override fun setLayoutId(viewType: Int): Int {
return android.R.layout.simple_list_item_1
}
override fun onBind(holder: Holder, RealPosition: Int, data: String) {
holder.setText(android.R.id.text1, data)
}
}
有头部，有尾部
//val rv:RecyclerView
//val list:ArrayList<String>
val adapter = object : CommonRecyclerAdapter<String>(this, list) {
override fun setLayoutId(viewType: Int): Int {
return android.R.layout.simple_list_item_1
}
override fun onBind(holder: Holder, RealPosition: Int, data: String) {
holder.setText(android.R.id.text1, data)
}
}
val mHeaderView = View.inflate(this, R.layout.view_header, null)
adapter.setHeaderView(mHeaderView)
val mFootView = View.inflate(this, R.layout.view_foot, null)
adapter.setFootView(mFootView)
rv.layoutManager = GridLayoutManager(this, 2)
rv.adapter = adapter
不同Item的使用
//val rv:RecyclerView
//val list:ArrayList<String>
val adapter = object : CommonRecyclerAdapter<String>(this, list) {
override fun itemViewType(position: Int): Int {
return if (position % 3 == 1) {
0x88
} else super.itemViewType(position)
}
override fun setLayoutId(viewType: Int): Int {
return when (viewType) {
0x88 -> R.layout.view_foot
else -> android.R.layout.simple_list_item_1
}
}
override fun onBind(holder: Holder, RealPosition: Int, data: String) {
when (holder.itemViewType) {
0x88 -> holder.setText(R.id.tv, data)
else -> holder.setText(android.R.id.text1, data)
}
}
}
rv.layoutManager = GridLayoutManager(this, 2)
//rv.layoutManager = LinearLayoutManager(this)
rv.adapter = adapter
