完成数据JSONArray，现在可以处理答复了，正如您在回复中看到的JSONArray，我将从数据中获取ID，因此我将该ID存储为Map中的key ex。
Map<String,Arraylist<ReplyCommentModel>>
所以String就是那个id。
现在在RecyclerView项目中的buttonOnClick上，我正在使用此代码->
viewRepliesButton.setOnClickListener(v -> {
if (collpased){
collpased = false;
replyRecyclerView.setVisibility(View.VISIBLE);
GroupAdapter<ViewHolder> adapter = new GroupAdapter<>();
replyRecyclerView.setAdapter(adapter);
replyRecyclerView.setLayoutManager(new LinearLayoutManager(context));
replyCommentModels = replyModelsMap.get(String.valueOf(model.comment_id));
if(replyCommentModels != null){
Log.e("replComments ","Size" +replyCommentModels.size());
for(ReplyCommentModel replyCommentModel : replyCommentModels){
adapter.add(new ReplyCommentItem(replyCommentModel,context));
}
}
viewRepliesButton.setText("hide");
} else {
collpased = true;
replyRecyclerView.setVisibility(View.GONE);
viewRepliesButton.setText("Tap to view reply");
}
});
但是地图中的所有项目都是可见的。在recyclerView中，我的代码中是否存在某些问题？ 由于我从适配器项模型传递的注释id的值是JSON响应中的Data键，因此您现在可以在上方看到，我在列表上单击并将其id传递给map以获取该特定id的数组列表，也许map是曾经这样做过，还是有其他一些更好的方式做到这一点？ Map <>与Arraylist tbh一起使用时的新功能，任何适当的指导将不胜感激
我这样保存我的地图
private Map<String,ArrayList<ReplyCommentModel>> replyModelMap = new HashMap<>();
try {
JSONObject obj = new JSONObject(response);
String status = obj.getString("result");
if (status.equals("success")) {
JSONArray jsonArray = obj.getJSONArray("data");
if(model.size() == 0){
fetchComments(jsonArray);
JSONObject replyObject = obj.getJSONObject("reply");
for(int i=0;i<model.size();i++){
JSONArray replyArrays = replyObject.getJSONArray(String.valueOf(model.get(i).comment_id));
for(int j=0;j<replyArrays.length();j++){
JSONObject jsonObject1 = replyArrays.getJSONObject(j);
Integer id = jsonObject1.getInt("id");
String name = jsonObject1.getString("name");
String comment_image = jsonObject1.getString("photo");
Integer user_id = jsonObject1.getInt("user_id");
String comment = jsonObject1.getString("comment");
String added_on = jsonObject1.getString("addedon");
String imageURl = Constant.IMAGE_URL+Constant.COMMENT_USER_IMAGE_URL+comment_image;
replyModel.add(new ReplyCommentModel(comment,name,imageURl,added_on,user_id,id));
}
if(replyModel != null){
replyModelMap.put(String.valueOf(model.get(i).comment_id),replyModel);
}
}
Log.e("ReplyModelMapSize","----> "+replyModelMap.size());
setUpRecyclerview();
}else{
model.clear();
fetchComments(jsonArray);
upDateRecyclerView();
}
}
}catch (Exception e){
e.printStackTrace();
}
1楼
尝试在内部for循环中初始化ReplyModel列表，似乎所有项都被添加到同一列表中，并且所有项都被添加到具有所有键的项中，因此得到具有所有键的整个列表。
for(int i=0;i<model.size();i++){
JSONArray replyArrays = replyObject.getJSONArray(String.valueOf(model.get(i).comment_id));
//Initialise inside the loop
ArrayList<ReplyCommentModel> replyModel = new ArrayList();
for(int j=0;j<replyArrays.length();j++){
JSONObject jsonObject1 = replyArrays.getJSONObject(j);
Integer id = jsonObject1.getInt("id");
String name = jsonObject1.getString("name");
String comment_image = jsonObject1.getString("photo");
Integer user_id = jsonObject1.getInt("user_id");
String comment = jsonObject1.getString("comment");
String added_on = jsonObject1.getString("addedon");
String imageURl = Constant.IMAGE_URL+Constant.COMMENT_USER_IMAGE_URL+comment_image;
replyModel.add(new ReplyCommentModel(comment,name,imageURl,added_on,user_id,id));
}
if(replyModel != null){
replyModelMap.put(String.valueOf(model.get(i).comment_id),replyModel);
}
}
