BlackjinBase

It is a my base library that collect common parts that are often used for rapid development.

Dependency

Then, add the library to your module in build.gradle

dependencies {
    implementation 'com.blackjin.library:blackjinbase:x.y.z'
}

Add Module

If you want to use by module, add blackjinbase module and then add the dependencies in build.gradle

dependencies {
   implementation project(':blackjinbase')
}

Enable DataBinding

BlackjinBase needs DataBinding

add the dataBinding element to your build.gradle file in the app module

android {
    ...
    dataBinding {
        enabled = true
    }
}

if your android studio's version is more than 4.0, you can use below code instead of upper that

android {
    ...
     buildFeatures{
            dataBinding = true
     }
}

Sample

You can see the helper class for recyclerview in sample

RecyclerViewFragment

SimpleRecyclerViewFragment

Use DiffUtil.Callback

val diffCallback = BaseDiffUtilCallback(this.items, items)
val diffResult = DiffUtil.calculateDiff(diffCallback)

SimpleAsyncRecyclerViewFragment

Use DiffUtil.ItemCallback for AsyncListDiffer

private val asyncDiffer = AsyncListDiffer(this, BaseDiffItemCallback<ITEM>())

SimpleListRecyclerViewFragment

Use ListAdapter for AsyncListDiffer and databinding

<androidx.recyclerview.widget.RecyclerView
           android:id="@+id/list_sample"
           android:layout_width="match_parent"
           android:layout_height="0dp"
           android:layout_weight="1"
           bind:itemLayoutId="@{@layout/item_sample}"
           bind:itemList="@{items}"
           tools:listitem="@layout/item_sample" />
