代码如下

public class MainActivity extends AppCompatActivity {
    private NestedScrollView scrollView;
    private RecyclerView recyclerView;

    

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        scrollView = (NestedScrollView) findViewById(R.id.scrollView);
        recyclerView = (RecyclerView) findViewById(R.id.recycler_view);
        
        recyclerView.setLayoutManager(new LinearLayoutManager(this));
        recyclerView.setAdapter(new DemoAdapter(this));
        recyclerView.setNestedScrollingEnabled(false);
    }
}

注意：setNestedScrollingEnabled该方法调用 设置为false即可实现嵌套的，NestedScrollView是专门为了兼容Mc design控件而生的
