【中文标题】从列表视图中搜索edittext中的项目显示错误的结果【英文标题】：Search item in edittext from listview showing wrong result 【发布时间】：2014-01-03 14:21:54 【问题描述】：尝试使用edittext搜索listview项目，点击搜索项目返回错误位置。
假设我从给定列表中搜索“C”，其中列表项如下“A”，“B”，“C”，“D”，“CC”，并得到正确的搜索结果，但一旦点击搜索项目，它返回错误的项目位置。
这里 Edittext addTextChangedListener ：
edtSearch.addTextChangedListener(new TextWatcher()
public void onTextChanged(CharSequence s, int start, int before,
int count)
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged();
public void beforeTextChanged(CharSequence s, int start, int count,
int after)
public void afterTextChanged(Editable s)
);

【问题讨论】：
您必须清除包含数据的数组列表，然后将它们填充到您过滤列表视图的位置。 请看下面我的回答，希望对你有所帮助。 向我们显示项目点击监听器列表 @vipul，我已经添加了完整的代码。 检查此链接 - 我认为有帮助 ***.com/questions/1737009/… 【参考方案1】：参考此代码：-
@Override
public void onTextChanged(CharSequence s, int start, int before, int count)
// TODO Auto-generated method stub
ArrayList<String> STOREID_SUB = new ArrayList<String>();
ArrayList<String> STORE_NAME_SUB = new ArrayList<String>();
ArrayList<String> PHOTO_SUB = new ArrayList<String>();
ArrayList<String> PLACE_STATUS_SUB = new ArrayList<String>();
final ArrayList<String> STORE_DESC_SUB = new ArrayList<String>();
textlength = searchText.getText().length();
for (int i = 0; i < STORE_NAME.size(); i++)
if (textlength <= STORE_NAME.get(i).length())
if (searchText.getText().toString().
equalsIgnoreCase((String) STORE_NAME.get(i).subSequence(0, textlength)))
STORE_NAME_SUB.add(STORE_NAME.get(i));
STOREID_SUB.add(STOREID.get(i));
PHOTO_SUB.add(PHOTO.get(i));
STORE_DESC_SUB.add(STORE_DESC.get(i));
PLACE_STATUS_SUB.add(PLACE_STATUS.get(i));
adapter=new StoreSearchListAdapter(context, R.drawable.ic_launcher, R.drawable.ic_launcher, STORE_NAME_SUB, PHOTO_SUB,STORE_DESC_SUB,PLACE_STATUS_SUB);
singlePlaceChooserList.setAdapter(adapter);
我在 onTextCahnged 方法中创建一个新的数组列表，然后使用这些值来设置我的适配器。
【讨论】：
【参考方案2】：将您的 onItemClick 更改为：
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3)
// TODO Auto-generated method
if (((String)adapter.getItem(position)).equals("Admin Cost"))
Intent int0 = new Intent(getApplicationContext(), Admincost.class);
startActivity(int0);
.........................
当您过滤列表时，项目会重新排列并且它们的位置会发生变化，因此请根据该位置上的值而不是位置导航到下一个活动。
【讨论】：
我猜这个字符串会返回所选的国家名称。如果这是真的，这将起作用。如果没有尝试打印该值并找出它返回的内容。 现在我的应用程序崩溃了，在过滤器项目上单击以获取新答案。 感谢您的回答，现在我已经解决了我的问题。请参阅我的答案中的代码。以上是关于从列表视图中搜索edittext中的项目显示错误的结果的主要内容，如果未能解决你的问题，请参考以下文章
