抱歉标题令人困惑（没有理由用几句话来解释我的问题）
这是我的情况：
我正在开发一个应用程序来收集邮票我有包含 2 个 JSONArray的JSON，"collectedStamp"并且这 2 个 JSONArrays分别 "unCollectedStamp"存储到2 个 ArrayLists"arraylistCollected"中，"arraylistUncollected"
而且我有1 个 GridView来显示所有收集和未收集的邮票
所以要将这2 个 ArrayList放入ListViewAdapter 我必须将两者合并"arraylistCollected"到"arraylistUncollected"1个名为"arraylistCombined"
现在所有邮票在 1 个 GridView 中正确显示，但我想检测已收集的邮票和未收集的邮票，以便用户知道女巫邮票已被收集，哪些未收集。例如，将收集的邮票制作成彩色和未收集的邮票黑白，或者
我不知道如何检测这两个数组的元素，"arraylistCollected"所以"arraylistUncollected" 以后我可以对他们的任何图像做任何事情。
您对解决这个问题有什么意见或想法？
这个 JSON 结果
{
"status": "1",
"tappedStamp": "15",
"message": "stamp message",
"stampimage": "stamp3.png",
"stampname": "stamp3",
"collectedStamp": [
{
"id": "14",
"stampname": "stamp2 ",
"message": "stamp2 message",
"stampimage": "stamp2.png"
},
{
"id": "15",
"stampname": "stamp3",
"message": "stamp message",
"stampimage": "stamp3.png"
}
],
"unCollectedStamp": [
{
"id": "12",
"stampname": "Testing MKH Stamp",
"message": "Testing MKH Stamp",
"stampimage": "award.png"
},
{
"id": "13",
"stampname": "stamp1",
"message": "stamp1 Message",
"stampimage": "stamp1.png"
},
{
"id": "16",
"stampname": "Testing MKH Stamp",
"message": "Testing MKH Stamp",
"stampimage": "award.png"
}
]
}

这是 ListViewAdapter

data = arraylist;
imageLoader = new ImageLoader(context);
}
@Override
public int getCount() {
return data.size();
}
@Override
public Object getItem(int position) {
return null;
}
@Override
public long getItemId(int position) {
return 0;
}
public View getView(final int position, View convertView, ViewGroup parent) {
// Declare Variables
TextView tvStampName;
ImageView stampImage;
inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View itemView = inflater.inflate(R.layout.single_stamp_layout, parent, false);
// Get the position
resultp = data.get(position);
tvStampName = (TextView) itemView.findViewById(R.id.tvStampName);
stampImage = (ImageView) itemView.findViewById(R.id.stampImage);
tvStampName.setText(resultp.get(StampsActivity.TAG_STAMP_NAME));
// Passes stampImage images URL into ImageLoader.class
imageLoader.DisplayImage(TAG_STAMP_IMAGE_URL+resultp.get(StampsActivity.TAG_STAMP_IMAGE), stampImage);
Animation myFadeInAnimation = AnimationUtils.loadAnimation(context, R.anim.fadein);
stampImage.startAnimation(myFadeInAnimation);

}
