当单击recycleview.i的项目时，我想获取该项目的ID并在Main活动的另一个服务中使用它们，recycleview工作正常，只是想从适配器获取ID并将其用于主要活动，这是我的代码适配器和其中显示
的主Activity类 private void loadrent() {
l.setVisibility(View.GONE);
shimmerLayout.setVisibility(View.VISIBLE);
shimmerLayout.startShimmerAnimation();

@Override
public void onResponse(String response) {
try {
Integer a;
shimmerLayout.stopShimmerAnimation();
shimmerLayout.setVisibility(View.GONE);
//converting the string to json array object
JSONObject jsonResponse = new JSONObject(response);
JSONArray array =jsonResponse.getJSONArray("data");
// JSONArray arrays =jsonResponse.getJSONArray("0");
//traversing through all the object
if(array != null && array.length() > 0 ) {
l.setVisibility(View.INVISIBLE);
for (int i = 0; i < array.length(); i++) {
//getting product object from json array
JSONObject product =array.getJSONObject(i);
//JSONObject products =arrays.getJSONObject(i);
//adding the product to product lists
productList.add(new Rent(

答案 0 :(得分：0)
首先：您可以创建一个用于提供回调监听器的接口：
result = [t for t in data if max(Counter(t).values()) < 3]
第二：您的适配器应保留侦听器，但活动应实现：
interface UpdateActivityListener {
void itemClicked(int id);
}
第三步：：设置为您的视图默认值public rentgestAdapter(Context mCtx, List<Rent> productList, UpdateActivityListener listener) {
this.mCtx = mCtx;
this.productList = productList;
this.listener = listener;
}
，并使用传递ID呼叫监听器。
