    }


    @Override
    protected void covert(BaseViewHolder holder, String data, int position) {
        ButterKnife.bind(this, holder.getView());
        rcycItemText.setText(data);
    }


}
           

public class RcycActivity extends AppCompatActivity {

    List<String> strings;
    @BindView(R.id.rcycview)
    RecyclerView rcycview;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_rcyc);
        ButterKnife.bind(this);
        init();
    }

    private void init() {
        strings = new ArrayList<>();
        for (int i = ; i < ; i++) {
            strings.add("封装RecyclerView" + i);
        }
        rcycview.setLayoutManager(new LinearLayoutManager(this));
        rcycview.setAdapter(new RecyclerAdapter(strings,this));

    }
