PagerLayout

A PagerGridLayoutManager combine PageView and GridLayoutManager.

  • replace "viewPager>recyclerView" with just only a "RecyclerView"
  • reduce memory using by cache all items
  • grid layout support
  • custom indicator drawable support
  • add lock, dot and corner for each item

Quick View

How To Use

  1. add PagerLayoutManager as recyclerView's layoutManager
recyclerView.layoutManager = PagerLayoutManager()
Kotlin
  1. set a adapter to recyclerView as usual
recyclerView.adapter = SlideAdapter(baseContext)
Kotlin
  1. set PagerSnapHelper to scroll like a PageView
PagerSnapHelper().attachToRecyclerView(recyclerView)
Kotlin

That's all!
We will layout all children automatically using pager grid.

  1. if you want a indicator , we supply 4 kind indicators as implements of PageIndicator. Dot, Line， Square, Drawable.
    just need a attachToRecyclerView.
dotIndicator.attachToRecyclerView(recyclerView)
lineIndicator.attachToRecyclerView(recyclerView)
lineIndicator2.attachToRecyclerView(recyclerView)
drawIndicator.attachToRecyclerView(recyclerView)
Kotlin
  1. if you need your item in RecyclerView with lock or dot, you can implementation lockitem,and control the value with xml define in Demo or java/kotlin code Demo

PagerLayout

Custom Grid

just like GridLayoutManager you can set the grid weights of each item

The default spanCount is 12, you can using this to layout children by all (1,2,3,4,6,12). Also you can custom this spanCount.
Here is a simple example with kotlin code:

recyclerView.layoutManager = PagerLayoutManager(12) {
    when (it) {
        37 -> SlideAdapter.TYPE_1
        in 0..1 -> SlideAdapter.TYPE_2
        in 18..20 -> SlideAdapter.TYPE_3
        in 46..51 -> SlideAdapter.TYPE_6
        in 56..58 -> SlideAdapter.TYPE_3
        else -> SlideAdapter.TYPE_4
    }
}
Kotlin

Cache Item By Type

Control to cache item just like RecyclerView for each type of item.

recyclerView.recycledViewPool.setMaxRecycledViews(SlideAdapter.TYPE_6, 20)
recyclerView.recycledViewPool.setMaxRecycledViews(SlideAdapter.TYPE_4, 20)
recyclerView.recycledViewPool.setMaxRecycledViews(SlideAdapter.TYPE_3, 4)
recyclerView.recycledViewPool.setMaxRecycledViews(SlideAdapter.TYPE_2, 4)
recyclerView.recycledViewPool.setMaxRecycledViews(SlideAdapter.TYPE_1, 4)
Kotlin

Indicator

You can set width, height, normalColor, selectColor, padding, round to indicator.
Also you can set a Bitmap as indicator

android:padding="8dp"
app:indicatorHeight="26dp"
app:indicatorWidth="26dp"
app:normalColor="@android:color/holo_blue_light"
app:selectColor="@android:color/holo_orange_light"
app:round="true"
XML

For detail config, here is a Demo for you.

Lock && Dot

Each item can be covered with lock and dot, and the number in dot, here is a Demo

lockItem.showNumber = false
lockItem.dotNumber = -1
lockItem.showLock = false
Kotlin

Also, you can control this with xml:

<com.abelhu.lockitem.LockItem
    android:id="@+id/iconView"
    android:layout_width="0dp"
    android:layout_height="0dp"
    android:padding="8dp"
    android:src="@color/colorAccent"
    app:cornerSize="8dp"
    app:dotBackgroundColor="@android:color/white"
    app:dotBackgroundRadio="0.5dp"
    app:dotBigRadio="8dp"
    app:dotNormalRadio="4dp"
    app:dotNumber="88"
    app:dotTextSize="12sp"
    app:layout_constraintDimensionRatio="w, 1:1"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"
    app:lock="@mipmap/icon_lock"
    app:lockBackgroundColor="#aa000000"
    app:lockHeight="23.5dp"
    app:lockText="@string/app_name"
    app:lockTextColor="@android:color/white"
    app:lockTextMargin="8dp"
    app:lockTextSize="12sp"
    app:lockWidth="21dp"
    app:showLock="true"
    app:showNumber="true"
    app:srcCompat="@drawable/ic_launcher_foreground"
    tools:ignore="ContentDescription" />
