Gridview的Android setOnTouchListener仅适用于第一行

Question

我正在开发一个自定义按钮，当我触摸gridview项时，内容必须更改背景并移动图像视图和文本，模拟按下的按钮，当按钮被释放时，所有元素都必须恢复原状。使用setOnTouchListener此规范有效，但对于第一行，当我单击另一行时，效果将应用于第一行。这是我的代码：

MainActivity.java：

        }

    @Override

        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }

    private class MenuAdapter extends BaseAdapter {

            int i=0;

            for (String des : botoes) {
                items.add(new Item(i,des,imagens[i]));
                i++;
            };


        }

        @Override

        }

        @Override

            return items.get(i).id;
        }

        @Override

            imagem = (ImageView) v.getTag(R.id.imgButton);

            Item item = (Item) getItem(i);

            //picture.setImageResource(item.drawableId);
            imagem.setImageResource(item.imagem);
            Texto.setText(item.texto);

            return v;
        }



    }
}

有关如何以其他方式做到这一点的任何建议，或者这是如何运作的？
