B4A Library [Lib, Chargeable] Amir_RecyclerView

New b4a library!

RecyclerView, an important part of the sdk and android for making a custom list with better Layout , animation , and fixed for large data set.

Amir_RecyclerView released new version that we call it AX_RecyclerView.

version 1.0.8 is last update for Amir_RecyclerView and we will work on AX_RecyclerView only in future.

RecyclerView Android X : https://developer.android.com/reference/androidx/recyclerview/widget/RecyclerView

"RecyclerView is part of the v7 support library which means you can use it on anything that has api 7 and up"

Advantages of using recyclerview instead listview:

• ViewHolder Pattern

​

In a ListView, it was recommended to use the ViewHolder pattern but it was never a compulsion. In case of RecyclerView, this is mandatory using the RecyclerView.ViewHolder class. This is one of the major differences between the ListView and the RecyclerView.​

​

• LayoutManager

​

This is another massive enhancement brought to the RecyclerView. In a ListView, the only type of view available is the vertical ListView. There is no official way to even implement a horizontal ListView.​

​

Now using a RecyclerView, we can have a:​

​

i) LinearLayoutManager - which supports both vertical and horizontal lists,​

ii) StaggeredLayoutManager - which supports Pinterest like staggered lists,​

iii) GridLayoutManager - which supports displaying grids as seen in Gallery apps.​

​

And the best thing is that we can do all these dynamically as we want.​

​

• Item Animator

​

ListViews are lacking in support of good animations, but the RecyclerView brings a whole new dimension to it. Using the RecyclerView.ItemAnimator class, animating the views becomes so much easy and intuitive.​

​

• Item Decoration

​

In case of ListViews, dynamically decorating items like adding borders or dividers was never easy. But in case of RecyclerView, the RecyclerView.ItemDecorator class gives huge control to the developers but makes things a bit more time consuming and complex.​

• OnItemTouchListener

​

Intercepting item clicks on a ListView was simple, thanks to its AdapterView.OnItemClickListener interface. But the RecyclerView gives much more power and control to its developers by the RecyclerView. OnItemTouchListener but it complicates things a bit for the developer.​

Really positively impressive.

Q1) Is it also possible to load own layouts onto the panels via LoadLayout("...")?

Q2) Is it possible to dynamically adjust the height of the individual panels to the content during the loading process?​

Really positively impressive.

Q1) Is it also possible to load own layouts onto the panels via LoadLayout("...")?

Q2) Is it possible to dynamically adjust the height of the individual panels to the content during the loading process?​

Answer for Q1 AND Q2 , is YES very easy :

Sub Globals
    Private ARV As Amir_RecyclerView
    Type Items ( itemTitle As String , itemDescription As String)
    Private AdapterList As List
End Sub

Sub Activity_Create(FirstTime As Boolean)
    AdapterList.Initialize
    ARV.Initializer("ARV").ListView.Build
    ARV.DefaultAdapter
    Activity.AddView(ARV , 0 , 0 , 100%x , 100%y)
  
    For i = 1 To 10
        Dim item As Items
        item.Initialize
        item.itemTitle = "Product title " & i
        item.itemDescription = "Discription of product number " & i
        AdapterList.Add(item)
    Next
    ARV.Adapter2.NotifyDataSetChanged
  
End Sub

Sub ARV_GetItemCount As Int
    Return AdapterList.Size
End Sub

Sub ARV_onCreateViewHolder (Parent As Panel,ViewType As Int)
    Parent.LoadLayout("1")
End Sub

Sub ARV_onBindViewHolder (Parent As Panel,Position As Int)
    Dim item = AdapterList.Get(Position) As Items
  
    Dim img As ImageView = Parent.GetView(0)
    Dim lbl1 As Label = Parent.GetView(1)
    Dim lbl2 As Label = Parent.GetView(2)
  
    img.Bitmap = LoadBitmapResize(File.DirAssets , "emoji_ (" & (Position+1) & ").png" , 42dip , 42dip , False)
    img.Gravity = Gravity.FILL
    lbl1.Text = item.itemTitle
    lbl2.Text = item.itemDescription
  
    Parent.Height = lbl2.Top + lbl2.Height + 10dip
      
End Sub
