使用方式一：XML布局中直接使用

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <com.test.festec.cehuaitem.widget.SideslipContainer
        android:id="@+id/sideslip_container01"
        android:layout_width="match_parent"
        android:layout_height="70dp"
        app:option_width="65dp">

        <com.test.festec.cehuaitem.widget.SideslipContent
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="horizontal">

            <TextView
                android:background="@color/d5"
                android:paddingTop="20dp"
                android:textAlignment="center"
                android:textSize="20sp"
                android:text="content"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

        </com.test.festec.cehuaitem.widget.SideslipContent>

        <com.test.festec.cehuaitem.widget.SideslipOption
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@color/blue"
            android:tag="add"
            android:text="增加" />

        <com.test.festec.cehuaitem.widget.SideslipOption
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@color/orange"
            android:tag="edit"
            android:text="編輯" />

        <com.test.festec.cehuaitem.widget.SideslipOption
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@color/red"
            android:tag="delete"
            android:text="刪除" />

    </com.test.festec.cehuaitem.widget.SideslipContainer>


</LinearLayout>

Activity中監(jiān)聽

class MainActivity : Activity() {

    private lateinit var binding: ActivityMainBinding

    private var options = mutableListOf("增加", "編輯", "刪除")
    private var optionBg = mutableListOf(R.color.blue, R.color.orange, R.color.red)

    @SuppressLint("UseCompatLoadingForDrawables")
    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        binding.sideslipContainer01.addOnClickListener(object : SideslipContainer.SideslipContainerOnClick {

            override fun optionOnClick(optionTag: Any) {
                Toast.makeText(this@MainActivity,"optionTag：$optionTag", Toast.LENGTH_SHORT).show()
                binding.sideslipContainer01.sideslipRecover()
            }

            override fun contentOnClick() {
                Toast.makeText(this@MainActivity,"content", Toast.LENGTH_SHORT).show()
                binding.sideslipContainer01.sideslipRecover()
            }

        })

    }

}

使用方式二：代碼方式使用

先定義一個容器文章來源地址http://www.zghlxwxcb.cn/news/detail-645236.html

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity">


    <LinearLayout
        android:id="@+id/container"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical" />


</LinearLayout>

Activity中動態(tài)添加

class MainActivity : Activity() {

    private lateinit var binding: ActivityMainBinding

    private var options = mutableListOf("增加", "編輯", "刪除")
    private var optionBg = mutableListOf(R.color.blue, R.color.orange, R.color.red)

    @SuppressLint("UseCompatLoadingForDrawables")
    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityMainBinding.inflate(layoutInflater)
        setContentView(binding.root)

        // 創(chuàng)建側(cè)滑容器，配置基礎(chǔ)參數(shù)
        val sideslip = SideslipContainer(this, DensityUtil.dp2px(this, 65f))
        val layoutParams = LinearLayout.LayoutParams(
            LinearLayout.LayoutParams.MATCH_PARENT,
            DensityUtil.dp2px(this, 70f)
        )
        sideslip.layoutParams = layoutParams

        // 創(chuàng)建側(cè)滑內(nèi)容
        val content = SideslipContent(this).apply {
            background = resources.getDrawable(R.color.black,null)
        }

        // 加入側(cè)滑容器中
        sideslip.addView(content)

        // 創(chuàng)建選項卡，并加入側(cè)滑容器中
        options.forEachIndexed { index, str ->
            val option = SideslipOption(this,str)
            option.text = str
            option.background = resources.getDrawable(optionBg[index], null)
            sideslip.addView(option)
        }

        // 點擊監(jiān)聽
        sideslip.addOnClickListener(object : SideslipContainer.SideslipContainerListener {
            override fun optionOnClick(optionTag: Any) {
                Log.e("TAG","optionTag：$optionTag")
            }

            override fun contentOnClick() {
                Log.e("TAG","content")
            }
        })

        binding.container.addView(sideslip)

    }

}

使用方式三：結(jié)合RecyclerView使用

重寫LayoutManager

// 重寫LayoutManager，動態(tài)讓RecyclerView 禁止/恢復 Y軸滾動
open class CustomLinerLayoutManager(context: Context) : LinearLayoutManager(context) {

    private var isScrollEnabled = true

    fun getEnabled(): Boolean {
        return isScrollEnabled
    }

    fun setScrollEnabled(flag: Boolean) {
        isScrollEnabled = flag
    }

    override fun canScrollVertically(): Boolean {
        return isScrollEnabled && super.canScrollVertically();
    }

}

重寫RecyclerView

class MyRecyclerView : RecyclerView {

    constructor(context: Context) : super(context)
    constructor(context: Context, attributeSet: AttributeSet) : super(context, attributeSet)

    init {
        addOnScrollListener(object : RecyclerView.OnScrollListener() {

            /**
             *
             * public static final int SCROLL_STATE_IDLE = 0;  :  RecyclerView 當前未滾動。
             *
             * public static final int SCROLL_STATE_DRAGGING = 1;  :  RecyclerView 當前正在被外部輸入（例如用戶觸摸輸入）拖動。
             *
             * public static final int SCROLL_STATE_SETTLING = 2;  :  RecyclerView 當前正在動畫到最終位置，而不是在外部控制。
             */
            override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
                if (newState == RecyclerView.SCROLL_STATE_DRAGGING) {
                    childrenRecover()
                }
            }
        })
    }

    // view初始化
    private var viewInit = false

    // 上一會觸摸的子View
    var originalChild: SideslipContainer? = null

    // 當前觸摸的子View
    var currentChild: SideslipContainer? = null

    private var customLayoutManager: CustomLinerLayoutManager? = null

    private var childMoveCallback = object : ChildOnTouchCallback {
        override fun currentChildMove() {
            childrenRecover()
        }

        override fun originalChild(originalSideslip: SideslipContainer?) {
            originalChild = originalSideslip
        }

        override fun currentChild(currentContainer: SideslipContainer?) {
            currentChild = currentContainer
        }

        override fun listStopYScroll() {
            // Log.e("TAG", "List停止?jié)L動")
            if (customLayoutManager!!.getEnabled()) {
                customLayoutManager?.setScrollEnabled(false)
            }
        }

        override fun listRecoverYScroll() {
            // Log.e("TAG", "List恢復滾動")
            if (!(customLayoutManager!!.getEnabled())) {
                customLayoutManager?.setScrollEnabled(true)
            }
        }

    }

    // 子View恢復
    private fun childrenRecover() {
        children.forEach {
            (it as SideslipContainer).sideslipRecover()
        }
    }

    override fun onViewAdded(child: View?) {
        // Log.e("TAG","onViewAdded")
        val sideslipContainer = (child as SideslipContainer)
        sideslipContainer.addOnChildMoveCallback(childMoveCallback)
    }

    // 當復用item，徹底超出屏幕，不可見時執(zhí)行
    override fun onViewRemoved(child: View?) {
        // Log.e("TAG","onViewRemoved")
        (child as SideslipContainer).sideslipStateRest()
    }

    override fun onWindowFocusChanged(hasWindowFocus: Boolean) {
        // Log.e("TAG","onWindowFocusChanged")
        super.onWindowFocusChanged(hasWindowFocus)
        if (!viewInit) {
            customLayoutManager = (layoutManager as CustomLinerLayoutManager)
        }
        viewInit = true
    }

    interface ChildOnTouchCallback {

        // 有子View側(cè)滑了
        fun currentChildMove()

        // 上一個觸摸的子View
        fun originalChild(originalSideslip: SideslipContainer?)

        // 當前觸摸的子View
        fun currentChild(currentContainer: SideslipContainer?)

        // 列表停止Y軸滾動
        fun listStopYScroll()

        // 列表恢復Y軸滾動
        fun listRecoverYScroll()

    }

}

RecyclerView適配器

class MyListAdapter(
    var context: Context,
    var data: MutableList<Info>
) : RecyclerView.Adapter<MyListAdapter.MyViewHolder>() {

    private var options = mutableListOf("增加", "編輯", "刪除")

    override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
        val sideslip = holder.itemView as SideslipContainer

        // 根據(jù)不同權(quán)限，添加不同的選項卡
        val optionsView = mutableListOf<SideslipOption>()
        if (data[position].level == 0) {

                Toast.makeText(context,"${holder.adapterPosition} -- optionTag：$optionTag",Toast.LENGTH_SHORT).show()
                sideslip.sideslipRecover()
            }

            override fun contentOnClick() {
                Toast.makeText(context,"${holder.adapterPosition} - content",Toast.LENGTH_SHORT).show()
                sideslip.sideslipRecover()
            }
        })
        holder.idTv.text = data[position].id.toString()
        holder.titleTv.text = data[position].title
        holder.describeTv.text = data[position].describe
    }

    override fun getItemCount(): Int {
        return data.size
    }

    @SuppressLint("UseCompatLoadingForDrawables")
    @RequiresApi(Build.VERSION_CODES.LOLLIPOP)
    private fun sideslipContainer(itemView: View): SideslipContainer {
        // 創(chuàng)建側(cè)滑容器，配置基礎(chǔ)參數(shù)
        val sideslip = SideslipContainer(context)

        // 創(chuàng)建側(cè)滑內(nèi)容
        val content = SideslipContent(context)
        content.addView(itemView)
