コードに必要な変更だけで、

  1. ImageViewim.setOnClickListener(this);のforループを追加する必要があります。

  2. 以下の方法を削除します

    im.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            ImageView iv=(ImageView) v;
            Log.e("sfas","-->"+iv.getId());
        }
    });

  3. onClickcListenerアクティビティにすでに実装しているので、 onClick（）をオーバーライドします。

ビューをsetId()作成すると、それが彼のIDになります。 http://developer.android.com/reference/android/view/View.html#setId(int）

でのIDを設定していImageViewますim.setId(i);。したがって、IDはiの値になります。これはどこかで追跡できます。

また、クラス全体ではなく、コードの関連部分のみを投稿してください
