B4A Library [Lib, Chargeable] Amir_RecyclerView

alimanam3386 · Sep 15, 2018

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.

please update your android sdk , it should solve your problem.

The problem is, I'm already using version 28, which is the latest version. My path is C:\android_sdk\platforms\android-28\android.jar.

I'm still getting

B4X:

java.lang.IndexOutOfBoundsException: Invalid item position 0(0). Item count:0 com.aghajari.rv.RecyclerView{28abdee3 VFED.... ......I. 0,0-0,0}, adapter:com.aghajari.rvplugins.Amir_RVItemPicker$Amir_RVItemPickerAdapter@35a940e0, layout:com.aghajari.rvplugins.PickerLayoutManager@38150f99, context:b4a.example.main@350e725e

when using the ItemPicker plugin. This error was reported by someone else on one of the previous pages as well.

The bug can easily be shown with this code:

B4X:

Sub Globals
    Private WheelPicker As Amir_RVItemPicker
    Private WheelData As List
    Private Wheel As Amir_RecyclerView
End Sub

Sub Activity_Create(Time As Boolean)
    WheelData.Initialize
    WheelData.Add("one")
    WheelData.Add("two")
    WheelData.Add("three")
    WheelData.Add("four")
    Wheel.Initializer("")
    Activity.AddView(Wheel,0,0,300dip,300dip)
    WheelPicker.Initialize("WheelPicker",Wheel)
    WheelPicker.SetAdapter(WheelData).LayoutSize(Wheel.width,Wheel.height).TextSize(32).TextColor(Colors.Black).Build
End Sub

Tested with Java 8 and Android 28.

I did some research and this is apparently a known issue. The suggestion often seen is to setAutoMeasureEnabled(false) on the LayoutManager.

EDIT: just tried on three different computers, all show the same error...

First get a backup from your sdk files and then download and copy & paste below files to your sdk folder.

wimpie3 · Mar 26, 2019

The example starts working when you add these files to the SDK folder. However, several other apps not using recyclerview are now giving problems.

When I compare my extras folder to the one from the ZIP above, the ZIP contains a directory called 'android' which has different versions of recyclerview inside.

@Erel I presume overwriting the SDK folder isn't the recommended way. What needs to be checked in the SDK manager in order to download the android directory in extras?

victormedranop · Mar 26, 2019

His is an amazing lib, well documented easy to implement.

Thanks alimanam3386

victor

wimpie3 · Mar 27, 2019

I think I have localized the problem. Your ZIP file comes with Android Support Repository v44.0.0 - this is not the latest version. All people who install B4A from scratch will have Android Support Repository v47.0.0. And Amir_RVItemPicker does not work with v47... can you please correct this? This is the cause of all the problems...

alimanam3386 · Mar 28, 2019

I just wrapped this lib for ARV nothing else.

wimpie3 · Mar 28, 2019

It's a shame because this is blocking me from finishing a large project. You only have to modify one line in the plugin.

B4X:

LayoutManager.setAutoMeasureEnabled(false);

I can't understand how can I blocking you to finishing your project!!!!?? it is not mandatory to use this plugin in your project. in other hand please be aware I am not your employee ,several times I explained to you I am not developer of this lib I just wrapped that nothing else. anyway I added you in my ignored users.

wimpie3 · Mar 28, 2019

I don't see why such agression is needed. I have always tried to be polite and constructive, posting source code to show where things are going wrong. I love working with your library, if not, I wouldn't care about it. I think it's normal that as a paying user, you can count on bugfixes, right? You can't just charge money and run away when things don't work as expected.

alimanam3386 · Mar 28, 2019

Sorry!, How can I explain it to you it is not a bug ? if was it should not working at all but works as expected in my sdk with android-28 and repository as you said with version 44 . It is a incompatibility between the orginal lib and wrapped of it with repository version higher than 44 .
I explained the solution for you. I know it is not ideal solution but it works so what can I do more ???????

wimpie3 · Mar 29, 2019

I agree, it works, thank you for helping me... but I'm happy to read you agree this is not ideal and I was hoping all the time you could find a solution for this. But thanks anyway.

alimanam3386 · Mar 29, 2019

Thanks for your understanding, I will try to find better way to solve the problem even try to find another lib to do same action as plugin.

New version of Amir_RecyclerView has been released Version 1.0.8

today , All of us have heard about AndroidX . thanks Erel , we can switch to AndroidX like a piece of cake.

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

This update includes 2 new plugin : Amir_RVAnimators AND AX_RVSelection

1.Amir_RVAnimators :
RecyclerView Animators is an Android library that allows developers to easily create RecyclerView with animations.
See more : https://github.com/wasabeef/recyclerview-animators

2.AX_RVSelection :
A RecyclerView addon library providing support for item selection. The library provides support for both touch and mouse driven selection. Developers retain control over the visual representation, and the policies controlling selection behavior (like which items are eligible for selection, and how many items can be selected.)
See more : https://developer.android.com/reference/androidx/recyclerview/selection/Selection

the plugins which starts with AX_ only works for AndroidX Sdk which means you should use AX_RecyclerView and update your sdk,b4a to support androidx.

All other plugins will work with androidx. you only need to Jetify your libraries
Except Amir_RVItemPicker . this plugin may has some problems with new sdk (not sure). we will replace this plugin with new androidx plugin soon.

And new update includes 2 important things

1. RVViewHolder And RVBasicAdapter classes :
with this adapter you can make your RecyclerView Adapter just like java.

2. FixableListView Layout :
new ListView Layout is special for chat applications. FixableListView will controll all possible errors.
it's easy to use :

B4X:

 ListView : RV.Initializer("RV").ListView.Vertical.Build

FixableListView :

B4X:

RV.Initializer("RV").FixableListView(False).Vertical.Build

thanks for your support

alimanam3386 · Jul 19, 2019

I tested the example in Android 4.2 and 4.4 and I got this errors:

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

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

B4X:

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

the download link will send soon.

Thanks

wimpie3 · Jul 19, 2019

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