如何从AsyncTask的postExecute方法中的Map获取结果?我无法从结果中获取结果吗?

How to get the results from Map in postExecute method of AsyncTask? I am not able to fetch results in results ?

    @Override
    protected void onPostExecute(Map<String,List<CommentModel>> results) {
        super.onPostExecute(results);
        for(int i=0;i<results.size();i++){
            String ar =results.get(i).get(commentModelList);
           // String content = commentModel.getContent();

            Toast.makeText(getApplicationContext(),"Hello",Toast.LENGTH_LONG).show();
            ExpandableListAdapter expandableListAdapter = new Expandablelistadapter(getApplicationContext(),parentlist,childlist);
            list.setAdapter(expandableListAdapter);



    }
}

推荐答案

String ar =results.get(i).get(commentModelList);

应更改为

CommentModel ar =results.get(commentModelList).get(i);

为避免混淆，将来请尝试将每个步骤分成不同的行:

To avoid confusion is the future try to separate each step into a different line:

List<CommentModel> resultList = results.get(commentModelList);
CommentModel ar = resultList.get(i);

另外，您在哪里关闭for循环?如果我正确理解了您要在代码中执行的操作，则希望遍历从地图获得的列表，而不要遍历地图以获取列表.所以应该更像是:

Also, where are you closing your for loop? If I understand what you are trying to do in your code correctly, you want to iterate over the list that you get from your map not iterate over your map to get the list. So it should be more like:

List<CommentModel> resultList = results.get(commentModelList);

for(int i=0;i<resultList.size();i++){
    CommentModel ar = resultList.get(i);

    // use 'ar' in the rest of your code
}
