Custom RecyclerView writed with Kotlin

Usage

import

// Project

    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}
// Module

init

Just init it like a simple RecyclerView:

val layoutManager = LinearLayoutManager(this)
layoutManager.orientation = LinearLayoutManager.VERTICAL
recyclerView.layoutManager = layoutManager
recyclerView.adapter = adapter

enable head refreshing and foot loading

These features are disabled by default. You can enable these features in XML or in your code:

<com.crease.listlikerecyclerview.view.ListLikeRecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    app:layoutManager="LinearLayoutManager"
    app:loadable="true"
    app:refreshable="true"/>

recyclerView.refreshEnabled = true
recyclerView.loadingEnabled = true

set refreshing status

recyclerView.isRefreshing = true

set RefreshListener

recyclerView.loadCallback = object : ListLikeRecyclerView
            .OnRecyclerViewLoadCallback {
            override fun onHeadRefresh() {
                mainBinding.root.postDelayed({
                    Toast.makeText(this@MainActivity, "Head refreshing finished", Toast
                            .LENGTH_LONG)
                            .show()
                    mainBinding.recyclerView.isRefreshing = false
                }, 1000)
            }

            override fun onFootLoad() {
                mainBinding.root.postDelayed({
                    Toast.makeText(this@MainActivity, "Foot loading finished", Toast.LENGTH_LONG).show()
                    // no more
                    mainBinding.recyclerView.noMore = true
                }, 1000)
            }
        }

set ItemClickListener

recyclerView.setOnItemClickListener(object : ListLikeRecyclerView
            .OnItemClickListener {
            override fun onItemClick(childView: View, itemPosition: Int) {
                Toast.makeText(this@MainActivity, itemPosition.toString(), Toast.LENGTH_LONG).show()
            }

            override fun onItemLongClick(childView: View, position: Int) {

            }
        })

custom header and footer

If you need customized header/footer, you can inherit HeadRefreshView or FootLoadView and implement the corresponding method

add/remove header/footer

recyclerView.addHeaderView(id, view)
recyclerView.addFooterView(id, view)
recyclerView.removeHeaderView(id)
recyclerView.removeFooterView(id)

drag/swipe item

You can handle the drag or sliding events by using ItemTouchCallback

val callbackNew = object : ItemTouchCallback() {
    override fun onItemSwiped(viewHolder: RecyclerView.ViewHolder, position: Int, direction: Int) {
        stringList.removeAt(position)

        adapter.removeItem(position)
    }

    override fun onItemCanMove(recyclerView: RecyclerView, viewHolder: RecyclerView.ViewHolder,
                               position: Int, targetViewHolder: RecyclerView.ViewHolder,
                               targetPosition: Int) = true

    override fun onItemMoved(recyclerView: RecyclerView, viewHolder: RecyclerView.ViewHolder, position: Int, targetViewHolder: RecyclerView.ViewHolder, targetPosition: Int, x: Int, y: Int) {
        if (position < targetPosition) {
            for (i in position until targetPosition) {
                Collections.swap(stringList, i, i + 1)
            }
        } else {
            for (i in position downTo (targetPosition + 1)) {
                Collections.swap(stringList, i, i - 1)
            }
        }

        adapter.moveItem(position, targetPosition)
    }
}

val touchHelper = ListItemTouchHelper(callbackNew)
touchHelper.attachToRecyclerView(mainBinding.recyclerView)

Please note that if you set long press events and drag events at the same time, you should set the long press events after drag events
