Answer 2

1 - あなたはGridViewコントロール内の各アイテムに使用するレイアウトを作成し、イメージビューとテキストビューを含む。

2 - あなたのxmlレイアウトであなたのGridViewを作成します。（主な活動）

3- ImageAdapterクラス（またはメソッド）を追加し、写真のメインリストのデータをバインドするために使用されます。

4-、私の悪い英語のためBaseAdapter

MyGridView = (GridView)findViewById(R.id.MyGridView); 
    MyGridView .setAdapter(new ImageAdapter(this)); 

申し訳から延びるImageAdapterクラスであなたのGridViewを記入し、それはあなたを助け願っています。
