我有6个图像按钮，点击它来改变，但是在第10个位置重复。我很无能，但我确信它与适配器的getView有关。因此，我发布了适配器的代码。帮助将不胜感激。

我不清楚你的问题或问题。但是看起来你在ListView上正确显示数据时遇到了一些特殊问题。在其中一个onClick（）：
中的getView（）中尝试此示例代码fianlHolder.imgBtnMorning.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View convertView) {
...
ImageButton imgBtn = (ImageButton) convertView;
imgBtn.setVisibility(View.VISIBLE);
...
notifyDataSetChanged();
...
注意：
notifyDataSetChanged强制调用强制刷新ListView。
