Installation (Kotlin DSL • Groovy )

Kotlin DSL

• Install jitpack

Locate your build.gradle.kts file in the root project and add :

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { setUrl("https://jitpack.io") } // add this line
    }
}

For those with a higher gradle version, find settings.gradle.kts in the root project folder and add :

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { setUrl("https://jitpack.io") } // add this line
    }
}

• Add the lazy adapter dependency

In your app module find build.gradle.kts and add :

  implementation("com.github.KotlinKenya:lazy-adapter:$version")

• Sync gradle and proceed use the library

Groovy

• Install jitpack

Locate your build.gradle file in the root project and add :

allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url "https://jitpack.io" } // add this line
    }
}

For those with a higher gradle version, find settings.gradle and add :

dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }  // add this line
    }
}

• Add Image Picker dependency

In your app module find build.gradle and add :

  implementation 'com.github.KotlinKenya:lazy-adapter:$version'

Usage

• let your data class extend the LazyCompare()

    data class Item (val name: String) : LazyCompare()

• create an xml file for your object

  <!-- in this example our layout is item_layout.xml  -->
  
  <?xml version="1.0" encoding="utf-8"?>
  <androidx.constraintlayout.widget.ConstraintLayout ...>
  
    <androidx.cardview.widget.CardView ...>
  
        <TextView
            android:id="@+id/tv_text"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:padding="16dp"
            android:text="TextView" />
  
    </androidx.cardview.widget.CardView>
  
  </androidx.constraintlayout.widget.ConstraintLayout>

• create an adapter from the LazyAdapter class

     val adapter = LazyAdapter<Item, LayoutItemBinding>()

• initialize the view

  adapter.onCreate { parent: ViewGroup -> 
    val inflater = LayoutInflater.from(parent.context)
    LayoutItemBinding.inflate(inflater, parent, false) 
  }

• bind the views

  adapter.onBind {item : Item ->
    // you can access all views in here
    tvText.text = item.name
  }

• set the adapter to the recyclerview and submitList

    recyclerview.adapter = adapter
    adapter.submitList(listOf<Item>()) // populate your list
