Integration

This library will be your life easier when you try to implement an adapater through Databinding. You just to bind your list and which layout you want to inflate, to one of the ListViewor RecyclerView that the library provides and the library will do the work for you.

<com.gc.databinidingadapters.DataBindingRecyclerView
            android:id="@+id/lvProducts"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:data="@{viewModel.products}"
            app:itemLayout="@layout/product_item"
            app:onItemClickListener="@{viewModel.itemClickListener}"/>

product_item.xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">
    <data>
        <variable
            name="viewModel"
            type="ProductItem" />
    </data>
    ...

If you want to have your list always updated, don´t worry, the library provides an ObservableList which works together with the adapters helping for the listviews are updated. You just to add, remove or update an item and the list view will be refreshed.

Any way altough you don't want to use a list from the library because you have a custom view whick works with a adapter, you are able to use an adapter from the library, for that, you just have to provide it two parameters and an optional listener if you want to process item click:

val adapter = DataBindingAdapter<Item>(list, R.layout.view_item, OnItemClickListener { item -> } )
