图像不能在我已经使用setImage（）和的getImage（该List.In父类中所示），但我不知道如何让图像ExpandableListMain（这是MainActivity）图像不能显示在列表中
private ArrayList<Parent> buildDummyData(String result) throws JSONException {
// Creating ArrayList of type parent class to store parent class objects
JSONArray json = new JSONArray(result);
ArrayList<Parent> list = new ArrayList<>();
for (int i = 1; i < json.length(); i++) {
JSONObject obj1 = json.getJSONObject(i);
Parent parent = new Parent();
parent.setName("" + i);
// parent.setImage(obj1.getImage("image"));----->this line shows an error
parent.setText1(obj1.getString("name"));
parent.setChildren(new ArrayList<Child>());
Child child = new Child();
child.setName("" + i);
child.setText1(obj1.getString("name"));
child.setText2(obj1.getString("mobile"));
child.setText3("hellooo");
child.setText4(obj1.getString("blood"));
//Add Child class object to parent class object
parent.getChildren().add(child);
list.add(parent);
}
return list;
