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.​

I switched to version 1.0.8. Is it normal a new file called Amir_RecyclerView.androidx.jar is added?

https://www.b4x.com/android/forum/threads/androidx-sdk.107236/#content

 

[asales]

Amir_RVChipsLayoutManager 1.01 support android +4

The reason for the error was that we used vector drawable for close button and android 4 doesn't support vector.
Make sure update aar file in your libs with new one

the download link will send soon.

It works. Thanks.

NOTE : you can change button image by this line on onBindViewHolder Or onCreateViewHolder :

Dim Jo As JavaObject = Holder.ButtonView
Jo.RunMethod("setImageDrawable",Array(Drawable))

A small addition in code:

Dim Drawable As BitmapDrawable
Drawable.Initialize(LoadBitmap(File.DirAssets,"close-btn.png"))
Dim Jo As JavaObject = Holder.ButtonView
Jo.RunMethod("setImageDrawable",Array(Drawable))

[kelevra1602]

In the example of Amir_RVStickyHeader if I add:

RecyclerView.SpaceItemDecoration.ListView (16dip, True, True)

when it passes through the spaces, the header disappears and reappears until the space ends, causing a strange blink

How could solve this without removing the space?

Hey @Amir i am unable to filter the items in recyclerview actually i am binding recyclerview with Objects and i am trying to filer the list with the itemname provided in searchbar but the data is not updating in ui altough i am calling notifyadapteer.Here is attached code

Sub modifydata(query As String)
    If rcyclrItems.Adapter=Null Then Return
    rvdata.Clear
    If query.Length=0 Then
        rvdata.AddAll(ItemList)
    Else
        
        'iDetails.rvdata.AddAll(iDetails.rcyclrItems.Utils.FilterSearchList("",iDetails.ItemList).Trim.SkipLowerCase.StartsWith(query))
        For i=0 To ItemList.Size-1
            Dim iData As ItemData
            iData.Initialize
            iData=ItemList1.Get(i)
            If iData.itemname.StartsWith(query) Then
                rvdata.Add(iData)
            End If
        Next
        rcyclrItems.Utils.FilterSearchList("CustomType",rvdata)
        Log("SAize is"&rvdata.Size)
        
    
    End If
        callnotifier
End Sub
public Sub callnotifier
    rcyclrItems.Adapter2.NotifyDataSetChanged
End Sub

Here idata is a custom type object like this
Type ItemData (itemno As String, itemname As String,qty As String,amount As String,Price As String)
