This library is available in jitPack which is the default Maven repository used in Android Studio.

Gradle

Step 1. Add it in your root build.gradle at the end of repositories

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

Step 2. Add the dependency in your apps module build.gradle

dependencies {
	 implementation 'com.github.manojbhadane:GenericAdapter:v1.4'
}

Usage

1. In App level build.gradle

dataBinding {
        enabled true
}

2. In Activity/Fragment (Java)

 mDataBinding.recylerview.setAdapter(new GenericAdapter<PeopleModel, ListitemMainBinding>(this, arrayList) {
            @Override
            public int getLayoutResId() {
                return R.layout.listitem_main;
            }

            @Override
            public void onBindData(PeopleModel model, int position, ListitemMainBinding dataBinding) {
                dataBinding.txtName.setText(model.getName());
                dataBinding.txtAddress.setText(model.getAddress());
            }

            @Override
            public void onItemClick(PeopleModel model, int position) {

            }
        });

3. In Activity/Fragment (Kotlin)

 var adapter = object : GenericAdapter<PeopleModel, ListitemMainBinding>(this, arrayList) {
            override fun getLayoutResId(): Int {
                return R.layout.listitem_main
            }

            override fun onBindData(model: PeopleModel?, position: Int, dataBinding: ListitemMainBinding?) {
                dataBinding!!.txtName.text = model.getName()
		dataBinding!!.txtAddress.text = model.getAddress()
            }

            override fun onItemClick(model: PeopleModel?, position: Int) {

            }
        }
	
dataBinding.recyclerview.layoutManager = LinearLayoutManager(this, RecyclerView.VERTICAL, false)
dataBinding.recyclerview.adapter = adapter

v1.2

Added list filtering capability to genericAdapter by extending GenericFilterAdapter class

Sample code of adapter with filter

mDataBinding.recylerview.setAdapter(new GenericFilterAdapter<PeopleModel, ListitemMainBinding>(this, arrayList) {
            @Override
            public int getLayoutResId() {
                return R.layout.listitem_main;
            }

            @Override
            public void onBindData(PeopleModel model, int position, ListitemMainBinding dataBinding) {
                dataBinding.txtName.setText(model.getName());
                dataBinding.txtAddress.setText(model.getAddress());
            }

            @Override
            public void onItemClick(PeopleModel model, int position) {

            }

            @Override
            public View getSearchField() {
                return mDataBinding.edtSearch;
            }

            @Override
            public ArrayList<PeopleModel> performFilter(String searchText, ArrayList<PeopleModel> originalList) {
                ArrayList<PeopleModel> filteredList = new ArrayList<>();
                for (PeopleModel row : originalList) {
                    if (row.getName().toLowerCase().contains(searchText.toLowerCase()) 
		    		|| row.getName().contains(searchText) 
				|| row.getAddress().toLowerCase().contains(searchText.toLowerCase())) {
                        filteredList.add(row);
                    }
                }

                return filteredList;
            }
        });
