Android 如何扩展用于显示列表的RecyclerView适配器<；对象>；包含列表的n个元素<；嵌套对象>；包含n个元素和其他数据

我有一个带有对象的模型。类包含

列表

和n个元素，它自己的

错误

对象：

public class Object {

    List<NestedObject> nestedObjects;

    Fault fault;
}

这是我的嵌套对象dapter.class，它仅适用于

列表的单个对象：

它仅适用于列表中的1个元素。如何将此代码扩展为
List
的n个元素列表？
如果我理解正确，您可以创建临时列表并将所有嵌套对象添加到其中。以下是设置适配器的示例：

List<NestedObject> tempNestedObjects = new ArrayList<>();
for (int i = 0; i < getObjectsList().size(); i++) {
    tempNestedObjects.addAll(getObjectsList().get(i).getNestedObjects());
}

NestedObjectsAdapter nestedObjectsAdapter = new NestedObjectsAdapter(getApplicationContext(), tempNestedObjects);
recyclerView.setAdapter(nestedObjectsAdapter);

此对象列表如下所示

[2, some value 1], [7, some value 2], [8, some value 3]

List<NestedObject> tempNestedObjects = new ArrayList<>();
LinkedHashMap<Integer, Fault> linkedHashMap = new LinkedHashMap<>();
for (int i = 0; i < getObjectsList().size(); i++) {
    tempNestedObjects.addAll(getObjectsList().get(i).getNestedObjects());
    linkedHashMap.put(tempNestedObjects.size() - 1, getObjectsList().get(i).getFault());
}

NestedObjectsAdapter nestedObjectsAdapter = new NestedObjectsAdapter(getApplicationContext(), tempNestedObjects, linkedHashMap);
recyclerView.setAdapter(nestedObjectsAdapter);

因此，设置适配器将如下所示

[2, some value 1], [7, some value 2], [8, some value 3]

List<NestedObject> tempNestedObjects = new ArrayList<>();
LinkedHashMap<Integer, Fault> linkedHashMap = new LinkedHashMap<>();
for (int i = 0; i < getObjectsList().size(); i++) {
    tempNestedObjects.addAll(getObjectsList().get(i).getNestedObjects());
    linkedHashMap.put(tempNestedObjects.size() - 1, getObjectsList().get(i).getFault());
}

NestedObjectsAdapter nestedObjectsAdapter = new NestedObjectsAdapter(getApplicationContext(), tempNestedObjects, linkedHashMap);
recyclerView.setAdapter(nestedObjectsAdapter);

适配器不能只包含嵌套对象，父对象有一些数据，我不能放弃它们。如果Object.class中没有更多的数据（除了列表），这似乎是个好方法。我不是100%确定，但应该是LinkedHashMap而不是LinkedHashMap，但这是个好方法。
[2, some value 1], [7, some value 2], [8, some value 3]

List<NestedObject> tempNestedObjects = new ArrayList<>();
LinkedHashMap<Integer, Fault> linkedHashMap = new LinkedHashMap<>();
for (int i = 0; i < getObjectsList().size(); i++) {
    tempNestedObjects.addAll(getObjectsList().get(i).getNestedObjects());
    linkedHashMap.put(tempNestedObjects.size() - 1, getObjectsList().get(i).getFault());
}

NestedObjectsAdapter nestedObjectsAdapter = new NestedObjectsAdapter(getApplicationContext(), tempNestedObjects, linkedHashMap);
recyclerView.setAdapter(nestedObjectsAdapter);

private LinkedHashMap<Integer, Fault> linkedHashMap;

    String someString= nestedObjectsList.get(position).getSomeString();
    Double someInt = nestedObjectsList.get(position).getSomeInt();
    Fault fault;

    linkedHashMap.forEach((key, value) -> {
        if (key >= position) {
            fault = value;
        }
    });

    holder.someStringTextView.setText(someString);
    holder.someIntTextView.setText(someInt);

    holder.someViewThatNeedsFaultValue.setSomething(fault);
}

public class NestedObject {

    String someString;
    int someInt;
    Fault fault;
    ...
}

List<NestedObject> tempNestedObjects = new ArrayList<>();
for (int i = 0; i < getObjectsList().size(); i++) {
    Object object = getObjectsList().get(i);
    for (int j = 0; j < object.getNestedObjects().size(); j++) {
        NestedObject nestedObject = object.getNestedObjects().get(j);
        nestedObject.setFault(object.getFault());
        tempNestedObjects.add(nestedObject);
    }
}

NestedObjectsAdapter nestedObjectsAdapter = new NestedObjectsAdapter(getApplicationContext(), tempNestedObjects);
recyclerView.setAdapter(nestedObjectsAdapter);

@Override
public void onBindViewHolder(ViewHolder holder, int position) {

    String someString= nestedObjectsList.get(position).getSomeString();
    Double someInt = nestedObjectsList.get(position).getSomeInt();
    Fault fault = nestedObjectsList.get(position).getFault();

    holder.someStringTextView.setText(someString);
    holder.someIntTextView.setText(someInt);

    holder.someViewThatNeedsFaultValue.setSomething(fault);
}
