AbsListView RecyclerView 通用适配器

说明

超简化代码，高阶函数参数简化为1，使用非常方便。多类型注意数据源的构造 data:List<Pair<Int,T>>

2.0版本合并log库： https://github.com/luohaolun/log

添加依赖

Project build.gradle

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

Module build.gradle

dependencies {
    implementation 'com.github.luohaolun:adapter:2.0'
}

BaseAdapter使用

通常

val data = mutableListOf<String>()
for (i in 0..10) {
    data.add(i.toString())
}

lvList.adapter = Adapter(data, R.layout.item_test) {
    tvNum.text = it
}

多类型Item

val data = mutableListOf<Pair<Int, String>>()

for (i in 0..20) {
	if (i < 4)
            data.add(Pair(0, i.toString()))
        else
            data.add(Pair(1, i.toString()))
    }

MultiAdapter

    lvList.adapter = MultiAdapter(data, SparseArray<Int>().apply { put(0, R.layout.item_test);put(1, R.layout.item_test_2) }) {
        when (type) {
            0 -> {
                tvNum.text = "$it  类型0"
            }
            1 -> {
                tvNum.text = "$it  类型1"
            }
        }
    }

MulAdapter

    lvList.adapter = MulAdapter(data, 0, R.layout.item_test) {
        tvNum.text = "$it  类型1"
    }.addItemType(1, R.layout.item_test_2) {
        tvNum.text = "$it  类型2"
    }

RecyclerView.Adapter使用

通常

val data = mutableListOf<String>()
for (i in 0..10) {
	data.add(i.toString())
}

recyList.adapter = RecyclerAdapter(data, R.layout.item_test) {
    tvNum.text = it
}.setOnItemClickListener(500) { //点击间隔 500ms
    Toast.makeText(this@MainActivity, "点击    $position    $it", Toast.LENGTH_SHORT).show()
}.setOnItemLongClickListener {
    Toast.makeText(this@MainActivity, "长按    $position     $it", Toast.LENGTH_SHORT).show()
}

多类型Item

val data = mutableListOf<Pair<Int, String>>()

for (i in 0..20) {
	if (i < 4)
            data.add(Pair(0, i.toString()))
        else
            data.add(Pair(1, i.toString()))
    }

MultiRecyclerAdapter

    recyList.adapter = MultiRecyclerAdapter(data, SparseArray<Int>().apply { put(0, R.layout.item_test);put(1, R.layout.item_test_2) }) {
        when (type) {
            0 -> {
                tvNum.text = it
            }
            1 -> {
                tvNum.text = it
            }
        }
    }.setOnItemClickListener {
        Toast.makeText(this@MainActivity, "点击    $position     $it", Toast.LENGTH_SHORT).show()
    }.setOnItemLongClickListener {
        Toast.makeText(this@MainActivity, "长按    $position     $it", Toast.LENGTH_SHORT).show()
    }

MulRecyclerAdapter

    recyList.adapter = MulRecyclerAdapter(data, 0, R.layout.item_test) {
        tvNum.text = it
    }.addItemType(1, R.layout.item_test_2) {
        tvNum.text = it
    }.setOnItemClickListener {
        Toast.makeText(this@MainActivity, "点击    $position     $it", Toast.LENGTH_SHORT).show()
    }.setOnItemLongClickListener {
        Toast.makeText(this@MainActivity, "长按    $position     $it", Toast.LENGTH_SHORT).show()
    }

下拉刷新和上拉加载RefreshLayout

使用

自带布局预览，RecyclerView可替换为任意View，如TextView、LinearLayout..

<k.lhl.refresh.RefreshLayout
    android:id="@+id/refresh"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:headerClass="k.lhl.test.MyHeaderView"   
    app:footerClass="k.lhl.test.MyFooterView"   
    app:empty="@layout/default_empty_view"    // 没有数据时显示的空布局  refresh.showEmpty()
    app:enableFooter="true"
    app:enableHeader="true">
    <androidx.recyclerview.widget.RecyclerView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
        tools:itemCount="10"
        tools:listitem="@layout/item_test" />
</k.lhl.refresh.RefreshLayout>

自定义头部或底部：

1.继承BaseHeaderOrFooterView

2.设置
xml：app:headerClass/footerClass = "k.lhl.test.MyHeaderView"  // 完整包路径
代码：refresh.setHeader(MyHeaderView::class.java)  // class

PullRecyclerView

继承自RefreshLayout，对RecyclerView的扩展

使用

<k.lhl.refresh.PullRecyclerView
    android:id="@+id/recyList"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:enableFooter="true"
    app:enableHeader="true"
    app:empty="@layout/default_empty_view"
    app:enableEmpty="true"                      // 数据源为空自动展示空布局视图
    app:footerClass="k.lhl.test.MyFooterView"
    app:headerClass="k.lhl.test.MyHeaderView"
    app:item="@layout/item_test"                // xml配置item后设置adapter可省略item布局
    app:itemDivider="@drawable/default_item_divider" />
