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.

It would be nice if you upload the source to demonstate instead of the APK. Or maybe additionally.

Very good sample, thanks.

I think that you can change this line and remove the materialicons.ttf file:

B4X:

Icon.Typeface=Typeface.LoadFromAssets("materialicons.ttf")

to this line:

B4X:

Icon.Typeface=Typeface.MATERIALICONS

Thanks, this Lib is a HUGE addon to B4A community, thank you for all the hard work you have put to this.

There are several plugins in this library.
I checked the documentation made by @fredo (thanks!), but I'm not sure what I can do with some of these plugins.
Would be nice have a descripton for the plugins and if I can use it without the Amir_RecyclerView, like the plugins Amir_ViewManager, Amir_Animation, etc.
Thanks.
