私のアプリは使用します
com.etsy.android.grid.StaggeredGridView
そして、ずらしたグリッドにカスタム項目を設定するアダプターがあります。そのグリッドに別のカスタム アイテムを追加したいと思います。これはできますか？
2 つのカスタム アイテム xml と 2 つのレイアウト アダプターがあります。staggeredgrid に両方を追加するにはどうすればよいですか? addVeiw() を使用してみましたが、staggeredGridview では使用できません。多分私は1つのアダプターだけを使うべきですか？
コードは最小限に抑えますが、もっと見たいかどうか尋ねてください。
