KM Quick Adapter with Databinding

You can easily crate RecyclerviewAdapter and PagedlistAdapter using databinding with this library.

You can take a look here for Android PagingLibrary. Pagedlist and PagedlistAdapter are components of PagingLibrary.

Usage

Enable dataBinding in app build.gradle. Add the following code for it in android scope.

Create RecyclerviewAdapter or PagedlistAdapter with KmBuilder

     android {  
	  ...
	  dataBinding {  
		  enabled true  
	  }  
     }

RecyclerView Adapter:

     val adapter = KmBuilder.getRvAdapter()
            .createBinding { parent, viewType ->
                //Create ViewDataBinding variable for your layout and return it
                val mBinding: ItemAdapterBinding = inflate(
                    LayoutInflater.from(context),
                    R.layout.item_adapter,
                    parent,
                    false
                )
                mBinding.viewModel = ItemViewModel(aplicationContext)
                mBinding.viewModel?.initListener(this)
                mBinding
            }
            .bindItem { binding, model ->
                //Set item to your item layout view model
                (binding as ItemAdapterBinding).viewModel?.setModel(model as TestModel)
            }
            .setDiffCallback { newList, oldList ->
                //You can set DiffUtil.Callback to adapter
                KmDiffCallback(newList, oldList)
            }
            .build()

PagedlistAdapter:

       val adapter = KmBuilder.getPagedListAdapter()
            .createBinding { parent, viewType ->
                val mBinding: ItemAdapterBinding = DataBindingUtil.inflate(
                    LayoutInflater.from(context),
                    R.layout.item_adapter,
                    parent,
                    false
                )
                mBinding.viewModel = ItemViewModel(applicationContext)
                mBinding.viewModel?.initListener(this)
                mBinding
            }
            .bindItem { binding, model ->
                (binding as ItemAdapterBinding).viewModel?.setModel(model as TestModel)
            }
            .setDiffCallback { 
                //You must return DiffUtil.ItemCallback
                diffCallback
            }
            .build()

Set adapter to your recyclerview:

      recyclerView.adapter = kmPagedListAdapter

And the set list to adapter:

      //For PagedlistAdapter
      (recyclerView.adapter as KmPagedlistAdapter).setList(pagedList as PagedList<Any>)

      //For RecyclerviewAdapter
      (recyclerView.adapter as KmRvAdapter).setList(list)

How is works with multi view type?

Implement createBinding method. Create ViewDataBinding object for each view type and return it.

      .createBinding { parent, viewType ->  
		  lateinit var binding: ViewDataBinding  
		  when (viewType) {  
			  0 -> {  
				  binding = inflate(  
					  LayoutInflater.from(context),  
		              R.layout.item_adapter,  
		              parent,  
		              false)}  
		      1 -> {  
				  binding = inflate(  
					  LayoutInflater.from(context),  
		              R.layout.item_adapter,  
		              parent,  
		              false)}
		  return binding
	  }

How is implement DiffUtil.ItemCallback for PagedlistAdapter

      val itemCallback = object : DiffUtil.ItemCallback<Any>() {  
		  override fun areItemsTheSame(oldItem: Any, newItem: Any) =  
		        oldItem == newItem  
  
		  override fun areContentsTheSame(oldItem: Any, newItem: Any) =  
		        oldItem == newItem  
	  }

.setDiffCallback method must return DiffUtil.ItemCallback from for PagedlistAdapter,must not be null.

How is implement DiffUtil.DiffCallback for RecyclerViewAdapter

      fun diffCallback(newList: List<Any>, oldList: List<Any>) = object : DiffUtil.Callback(){  
		  override fun areItemsTheSame(p0: Int, p1: Int) = newList[p0] == oldList[p0]  
  
		  override fun getOldListSize() = oldList.size  
  
		  override fun getNewListSize() = newList.size  
  
		  override fun areContentsTheSame(p0: Int, p1: Int) = newList[p0] == oldList[p0]  
}

.setDiffCallback method must return DiffUtil.Callback from for RecyclerViewAdapter. If you don't implement this method,default DiffUtilCallback works like example.

Download

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

allprojects {
	repositories {
		...
		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

Add it in app build.gradle

dependencies {
	    compile 'com.github.smhdk:KM-Quick-Adapter:v1.0.0'
	}
