当在 ListView 中调用 2 个自定义布局时，列表视图项在滚动时随机播放

Question

我在 1 个列表视图中调用 2 个布局

一个是用于文本视图和编辑文本的线性，另一个只是一个微调器

但是，当我尝试通过程序调用线性布局中的项目时(下面给出的代码(， 每次滚动列表时，都会对项目进行随机排列或从序列中重新定位。

没有显示错误，但不知何故会发生这种情况。

我希望列表被调用一次并保持顺序。

任何帮助都是非常可观的。 下面是我的代码

Fillup_Details.java

public class Fillup_Details extends AppCompatActivity {
private ListView listView;
Spinner spinner;
ArrayList<ListViemItems> listViemItemses; 
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fillup__details);
listView = (ListView) findViewById(R.id.listFillupDetails);
spinner = (Spinner) findViewById(R.id.spnrFillupDetails);

listViemItemses = new ArrayList<ListViemItems>();
ListViemItems items1 = new ListViemItems();
items1.setListItems("ListItem1");
items1.setOddoreven(0);
listViemItemses.add(items1);
ListViemItems items2 = new ListViemItems();
items2.setListItems("ListItem2");
items2.setOddoreven(0);

//.....many more objects

ListViemItems itemspnr = new ListViemItems();

FillupDetailsList fillupDetailsList = new FillupDetailsList(Fillup_Details.this, listViemItemses);
listView.setAdapter(fillupDetailsList);

Answer 1

我得到了答案，我所要做的就是在开关大小写中进行以下更改

@Override
public View getView(int position, View convertView, ViewGroup viewGroup) {
int type = getItemViewType(position);
viewHolder = new ViewHolder();
switch (type) {
case TYPE_LIST_ITEMS:
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.fillup_details_layout, null);
}
viewHolder.txtItem = convertView.findViewById(R.id.txtFillupDetails);
ListViemItems detail_position = listViemItems.get(position);
viewHolder.txtItem.setText(detail_position.getListItems());
break;
case TYPE_SPINNER_ITEMS:
if (convertView == null) {
convertView = layoutInflater.inflate(R.layout.fillup_details_layout_spinner, null);
}
ListViemItems detail_position2 = listViemItems.get(position);
ArrayAdapter<String> adptrSpnrItem =
new ArrayAdapter<String>(context, R.layout.spinner_item, detail_position2.getSpinnerItems());
adptrSpnrItem.setDropDownViewResource(R.layout.spinner_item);
viewHolder.spinner = (Spinner) convertView.findViewById(R.id.spnrFillupDetails);
viewHolder.spinner.setAdapter(adptrSpnrItem);
break;
}
return convertView;
}
