Question

enter image description here

我的列表视图项中有一些条目。

当我点击项目时首先像按钮....只有像按钮颜色值的最后项目正在改变。当我点击项目第二个像按钮....只有像按钮颜色值的最后项目正在改变。但是

当我点击第一项时，我得到position = 0和offer_id = O101

当我点击第二项时，我得到position = 1并且offer_id = O103

当我点击第三项时，我得到position = 2和offer_id = O104

每当我点击任何列表视图项目的任何类似按钮时......列表视图颜色的最后一项的类似按钮就会改变。

我希望每当我点击列表项的任何类似按钮时，只有该列表项的类似按钮才会改变。如何纠正这个问题。这是我的代码......

您应该在OnClickListener中单击布尔值。由于它现在是全球性的，它会影响所有按钮。

holder.b1.setOnClickListener(new View.OnClickListener() {
        private boolean clicked = false;

        @Override
        public void onClick(View v) {
            String offerid = id_offiers_list.get(position);
            System.out.println(offerid);
            if (clicked) {
                System.out.println(position);
                holder.b1
                        .setBackgroundResource(R.drawable.like_icon_hover);
                holder.tv.setTextColor(Color.parseColor("#eaa232"));
                clicked = false;

            } else {
                System.out.println(position);
                holder.b1.setBackgroundResource(R.drawable.like_icon);
                holder.tv.setTextColor(Color.parseColor("#454545"));
                clicked = true;
            }
        }
    });
