アダプターでStickyGridHeadersを使用しています。グリッドからアイテムを使用しようとするまで、すべて正常に動作しますAnimation(削除されたときにアイテムをフェードアウトしたい)。

getView のこの部分は機能します。

public View getView(int position, View convertView, final ViewGroup parent) {
    ViewHolder holder;


    if (convertView == null) {
        convertView = myInflater.inflate(R.layout.item_savedsearchlist,
                null);

        holder = new ViewHolder();
        holder.Tv1 = (TextView) convertView.findViewById(R.id.textView1);

        convertView.setTag(holder);
    }

    else {
        holder = (ViewHolder) convertView.getTag();

    }

    holder.Deletebtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {


            Animation anim = AnimationUtils.loadAnimation(ctx,
                    android.R.anim.slide_out_right);

            anim.setAnimationListener(new Animation.AnimationListener() {

                removeThisItem(); 
                notifiyDataSetChanged; 

        }
    });

    return convertView;
}

これはしません:

public View getView(int position, View convertView, final ViewGroup parent) {
    ViewHolder holder;


    if (convertView == null) {
        convertView = myInflater.inflate(R.layout.item_savedsearchlist,
                null);

        holder = new ViewHolder();
        holder.Tv1 = (TextView) convertView.findViewById(R.id.textView1);

        convertView.setTag(holder);
    }

    else {
        holder = (ViewHolder) convertView.getTag();

    }

    final View rc = holder.Tv1;     // I tried this with different Views from the item layout

    holder.Deletebtn.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {


            Animation anim = AnimationUtils.loadAnimation(ctx,
                    android.R.anim.slide_out_right);

            anim.setAnimationListener(new Animation.AnimationListener() {

                @Override
                public void onAnimationStart(Animation animation) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onAnimationRepeat(Animation animation) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onAnimationEnd(Animation animation) {
                    // TODO Auto-generated method stub

                    removeThisItem(); 
                    notifyDataSetChanged(); 


                }
            });

            rc.startAnimation(anim);

        }
    });


    return convertView;
}

アイテムの膨張したレイアウトが GridHeader と何の関係があるのか​​ 本当にわかりません。アイデアはありますか?:)

これでctxを初期化し、その後これを使用できます

DetailsAdapter(MainActivity.this)

public DetailsAdapter(MainActivity ctx) {

        mInflater = LayoutInflater.from(ctx.getBaseContext());
    }

    Animation anim = AnimationUtils.loadAnimation(ctx,
                        android.R.anim.slide_out_right);
