SimplifiedRecyclerview

An android library to help you get rid of boiler plate code when setting up Recyclerview

Download

You can grab SimplifiedRecyclerview via Maven:

<dependency>
  <groupId>io.andronicus.simplifiedrecyclerview</groupId>
  <artifactId>simplifiedrecyclerview</artifactId>
  <version>1.0.4</version>
  <type>pom</type>
</dependency>

or Gradle:

dependencies {
  implementation 'io.andronicus.simplifiedrecyclerview:simplifiedrecyclerview:1.0.4'
}

Usage

To be able to initialize MyAdapter, you will need 3 arguments, the layout id of Recyclerview viewholder list item, list of items you are interested in displaying and lastly implementation of ViewHolderCallbacks to handle binding data and view holder click events.

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RecyclerView recyclerView = findViewById(R.id.recyclerview);
        recyclerView.setLayoutManager(new LinearLayoutManager(this)); 
        List<String> strings = new ArrayList<>();
        strings.add("1");
        strings.add("2");
        strings.add("3");

        MyAdapter adapter = new MyAdapter<>(R.layout.list_item,strings,this);
        recyclerView.setAdapter(adapter);

    }

I passed *this for the 3rd argument above because MainActivity implements ViewHolderCallbacks as shown below. The first method bindDataToViews allows you to bind data to views inside ViewHolder e.g Textviews... and the last method handles click events on the View holder.

 public class MainActivity extends AppCompatActivity implements MyAdapter.ViewHolderCallbacks<String> {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        RecyclerView recyclerView = findViewById(R.id.recyclerview);
        recyclerView.setLayoutManager(new LinearLayoutManager(this)); 
        List<String> strings = new ArrayList<>();
        strings.add("1");
        strings.add("2");
        strings.add("3");
        
        MyAdapter adapter = new MyAdapter<>(R.layout.list_item,strings,this);
        recyclerView.setAdapter(adapter);
    }
    
    /*
    * Bind data to your views as you would normally do
    * in the view holder
    * */
    @Override
    public void bindDataToViews(String item, View view) {
        TextView textView = view.findViewById(R.id.tv_test);
        textView.setText(item);
    }

    /*
    * Handle click events from the view holder here
    * */
    @Override
    public void onViewHolderClick(String item,int position) {
        Toast.makeText(this, "Clicked at position" +  position, Toast.LENGTH_SHORT).show();
    }
    
    /*
    * Optionally you can turn your adapter to a field in
    * this case mAdapter and use it to get all or get one item
    * as illustrated below
    * */
    /*
    * Get all items from the Adapter
    * */
    private List<String> getAllItems(){
        return mAdapter.getAllItems();
    }

    /*
     * Get one item from the Adapter
     * */
    private String getOneItem(int position){
        return mAdapter.getItemAtPosition(position);
    }
    
    /*
     * Refresh or Update data
     * */
    private void setData(List<String> data){
        this.mAdapter.setData(data);
    }
}

With that, your recyclerview is good to go.
