RecyclerView基本使用Demo

MainActivity

  1. public class MainActivity extends ListActivity {
  2. protected void onCreate(Bundle savedInstanceState) {
  3. super.onCreate(savedInstanceState);
  4. String[] array = {"基础,点击下试试",
  5. "添加",
  6. "删除",
  7. "ListView",
  8. "横向的GridView",
  9. "横向瀑布流",
  10. "纵向瀑布流",
  11. "分割线 ItemDecoration",
  12. "BaseRecyclerViewAdapterHelper基本使用"};
  13. setListAdapter(new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, new ArrayList<>(Arrays.asList(array))));
  14. }
  15. @Override
  16. protected void onListItemClick(ListView l, View v, int position, long id) {
  17. if (position <= 6) {
  18. Intent intent = new Intent(this, RecyclerViewActivity.class);
  19. intent.putExtra("type", position);
  20. startActivity(intent);
  21. } else if (position == 7) {
  22. startActivity(new Intent(this, RV_ItemDecorationActivity.class));
  23. } else if (position == 8) {
  24. startActivity(new Intent(this, BRVAHActivity.class));
  25. }
  26. }
  27. }

RecyclerViewActivity
