滑动冲突解决方案

非嵌套滑动 | 嵌套滑动

相比起非嵌套滑动的自定义分发事件的方案，嵌套滑动冲突有比较成熟的 Google 解决方案：NestedScrolling 。

三层嵌套的滑动冲突

嵌套滑动

UI 层级如下：

  • 最外层（底层）是一个具有下拉刷新功能的布局
  • 中层是本库提供的控件 StickNestedLayout ，解决导航栏吸顶，以及内外层的滑动冲突
  • 最内层（上层）依次是 headView / navView / contentView ，对应上部的内容区域，中部的吸顶导航栏区域，下部的 ViewPager 区域
  • ViewPager 里面有 RecyclerView 列表

StickNestedLayout

使用

你可以通过 StickNestedLayout 轻松地完成这种页面。

<RefreshLayout
    android:id="@+id/refreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <mobile.yy.com.nestedtouch.StickyNestedLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <include
            android:id="@id/stickyHeadView"
            layout="@layout/moment_head_view" />

        <NavView
            android:id="@id/stickyNavView"
            android:layout_width="match_parent"
            android:layout_height="40dp" />

        <android.support.v4.view.ViewPager
            android:id="@id/stickyContentView"
            android:layout_width="match_parent"
            android:layout_height="match_parent" />
    </mobile.yy.com.nestedtouch.StickyNestedLayout>
</RefreshLayout>

其中 headView / navView / contentView 的id必须为 stickyHeadView / stickyNavView / stickyContentView

可以通过运行工程 nestedtouchsample 查看具体代码。例子中涉及的其他第三方库有下拉刷新控件 SmartRefreshLayout 和导航栏 PagerSlidingTabStrip ，部分参考 StickNavLayout

配置

最新版本：

  1. 项目build.gradle添加

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

  2. 对应模块添加依赖

    dependencies {
	compile 'com.github.YvesCheung.TouchEventBus:nestedtouch:x.y.z'
}
