How to use

layout:

<!-- view_item.xml -->
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    android:gravity="center"
    android:padding="5dp">

    <TextView
        android:id="@+id/text_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:gravity="center"/>

    <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:text="CLICK ME"
        android:padding="10dp"
        android:gravity="center"/>

</LinearLayout>

Adapter:

public class MyAdapter extends BaseRecyclerViewAdapter<ViewItemBinding, String> {

    public MyAdapter(List<String> list) {
        super(R.layout.view_item, list);
    }

    @Override
    public void onBaseBindViewHolder(@NonNull ViewItemBinding binding, String s, int i) {
        //初始化内容
        binding.textView.setText(s);

        //设置点击事件，然后在Activity的Adapter对象的回调方法里进行操作
        setOnClick(binding.button, i);

        //也可以直接设置点击
        /*binding.button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //todo
            }
        });*/
    }
}

Activity:

public class MainActivity extends AppCompatActivity {

    ActivityMainBinding binding;
    List<String> list;
    MyAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        binding.recyclerView.setLayoutManager(new LinearLayoutManager(this));

        initData();
        initAdapter();
    }

    void initData() {
        list = new ArrayList<>();
        for (int i=0; i<20; i++) {
            list.add("ELEMENT " + i);
        }
    }

    void initAdapter() {
        adapter = new MyAdapter(list);
        binding.recyclerView.setAdapter(adapter);
        adapter.setOnClickListener(new BaseRecyclerViewAdapter.OnViewClickListener<String>() {
            @Override
            public void onClick(View v, String s, int i) {
                switch (v.getId()) {
                    case R.id.button:
                        showToast("Click Button ," + s + "," + i);
                        break;
                }
            }
        });
    }

    Toast toast;
    void showToast(String s) {
        if (toast != null) {
            toast.cancel();
        }
        toast = Toast.makeText(MainActivity.this, s, Toast.LENGTH_SHORT);
        toast.show();
    }
}
