做项目时一个listview 里面嵌套ediTtext 滑动之后 保存数据

这个项目做的时间 我们的需求是做一个填空题来做的，当时感觉非常难，现在回头看下实际也挺简单的。算了还是记录下吧，也有些难点。项目中的数据比较复杂 所以我自己写了一个小的Demo。Adapter里面

public class MyAdapter extends BaseAdapter {
private Context mCtx;
private List<ItemBean> mList = new ArrayList<>();
//这里使用treeMap不适用hashMap是因为 treeMap里面是有序的   而hashMap是乱序（这里一定要记住 这是一个item的 数据，而不是整体的  这里总是弄迷）
TreeMap<Integer, DateViewForPosition> treeMapDate = new TreeMap<>();
ArrayList<QuestionNumberCell> questionNumberCells = null;
TreeMap<String, String> emptyDataList = null;
DateViewForPosition dataView;

public MyAdapter(Context context, List<ItemBean> list) {
this.mCtx = context;
this.mList = list;
}

@Override
public int getCount() {
return mList.size();
}

@Override
public Object getItem(int position) {
return mList.get(position);
}

@Override
public long getItemId(int position) {
return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
final Holder holder;
if (convertView == null) {
holder = new Holder();
convertView = LayoutInflater.from(mCtx).inflate(R.layout.item, null);
holder.title = (TextView) convertView.findViewById(R.id.question_title_tv);
holder.answerLayout = (LinearLayout) convertView.findViewById(R.id.answer_layout);
convertView.setTag(holder);
} else {
holder = (Holder) convertView.getTag();
}
ItemBean bean = mList.get(position);
holder.title.setText(bean.getContent());

if (treeMapDate.get(position) == null) {
dataView = new DateViewForPosition();
} else {
dataView = treeMapDate.get(position);//从里面获取保存的答案
}

if (dataView.getQuestionNumberCellsDate().size() != 0 && dataView.getQuestionNumberCellsNum().size() != 0) {
questionNumberCells = dataView.getQuestionNumberCellsNum();
emptyDataList = dataView.getQuestionNumberCellsDate();
} else {
questionNumberCells = new ArrayList<>();
emptyDataList = new TreeMap<>();
dataView.setQuestionNumberCellsDate(emptyDataList);
dataView.setQuestionNumberCellsNum(questionNumberCells);
treeMapDate.put(position, dataView);
}

holder.answerLayout.removeAllViews();//每次进来都是不同的item了  所以就要清空
int emptyNumber = bean.getEmptemNum();//框框的数量
if (questionNumberCells.size() <= 0) {//没有数据，需要绘制边框      先针对框框进行处理
int number = 1, viewIndex = 0;
for (int i = 0; i < emptyNumber; i = i + 2) {
QuestionNumberCell questionNumberCell = new QuestionNumberCell(mCtx);
questionNumberCell.setOnChangeListener(new DataChangeListener());
questionNumberCell.init(number);//传进去num是框前面的数字
questionNumberCell.setPosition(position);
questionNumberCell.setIndex(viewIndex);//下标
holder.answerLayout.addView(questionNumberCell);
number += 2;
if (i != 0 && emptyNumber - i == 1 && emptyNumber % i == 1) {//单个的（除了1）
questionNumberCell.disableRightView();
emptyDataList.put(position + "_" + viewIndex + "_" + "0", ""); //这里这样操作 是为了下次绘制的时候没有点击的框没输入的 没被存起来
} else if (emptyNumber == 1) {//一个的
questionNumberCell.disableRightView();
emptyDataList.put(position + "_" + viewIndex + "_" + "0", "");
} else {//双个的
emptyDataList.put(position + "_" + viewIndex + "_" + "0", "");
emptyDataList.put(position + "_" + viewIndex + "_" + "1", "");
}
questionNumberCells.add(questionNumberCell);
viewIndex++;
}
} else {
holder.answerLayout.removeAllViews();
for (int i = 0; i < questionNumberCells.size(); i++) {
holder.answerLayout.addView(questionNumberCells.get(i));
}
}
//在针对数据进行处理
if (emptyDataList.size() > 0) {  //有数据
int index = 0;
for (int i = 0; i < emptyNumber; i = i + 2) {
QuestionNumberCell questionNumberCell = questionNumberCells.get(index);
if (i != 0 && emptyNumber - i == 1 && emptyNumber % i == 1) {//单个的（除了1）
questionNumberCell.setAnswer(emptyDataList.get(position + "_" + index + "_" + "0"));
} else if (emptyNumber == 1) {//一个的
questionNumberCell.setAnswer(emptyDataList.get(position + "_" + index + "_" + "0"));
} else {//双个的
questionNumberCell.setAllAnswer(emptyDataList.get(position + "_" + index + "_" + "0"), emptyDataList.get(position + "_" + index + "_" + "1"));
}
index++;
}
} else {
int index = 0;
for (int i = 0; i < emptyNumber; i = i + 2) {
QuestionNumberCell questionNumberCell = questionNumberCells.get(index);
if (i != 0 && emptyNumber - i == 1 && emptyNumber % i == 1) {//单个的（除了1）
questionNumberCell.setAnswer("");
} else if (emptyNumber == 1) {//一个的
questionNumberCell.setAnswer("");
} else {//双个的
questionNumberCell.setAllAnswer("", "");
}
index++;
}
}
return convertView;
}

//监听输入框 失去焦点的事件
public class DataChangeListener implements InputDataChangeListener {
@Override                        //index是第几行  state代表 左边的框为0  右边为1
public void onDataChange(int position, int index, String data, int state) {
Log.d("ydd", "onDataChange============ position =  " + position + "index = " + index + "date=" + data + "state=" + state);
DateViewForPosition dateViewForPosition = treeMapDate.get(position);
TreeMap<String, String> questionNumberCellsDate = dateViewForPosition.getQuestionNumberCellsDate();
questionNumberCellsDate.put(position + "_" + index + "_" + state, data);
