经过大量的时间在这里和其他地方搜索，我无法找到解决方案。
所以这是我的问题。
我创建了一个列表视图，最重要的是我添加了一个搜索栏。
当我使用搜索栏时，过滤结果...当我点击第7项时，它不是打开特定的点击活动，即7，而是始终从第一个开始。
我期待着你们的帮助;因为我需要它！

public class Group extends ListActivity {
// ArrayList thats going to hold the search results
ArrayList<HashMap<String, Object>> searchResults;
// ArrayList that will hold the original Data
ArrayList<HashMap<String, Object>> originalValues;
LayoutInflater inflater;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.grouplist);
final EditText searchBox = (EditText) findViewById(R.id.searchBox);
ListView playersListView = (ListView) findViewById(android.R.id.list);
inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final EditText searchBox = (EditText) findViewById(R.id.searchBox);
ListView playersListView = (ListView) findViewById(android.R.id.list);
inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// these arrays are just the data that
// I'll be using to populate the ArrayList
String names[] = {/*list of names*/ };
String teams[] = {/*list of teams*/};
Integer[] photos = {R.drawable.... /*list of drawables*/};
Integer[] id ={/*Position*/};
originalValues = new ArrayList<HashMap<String, Object>>();
// temporary HashMap for populating the Items in the ListView
HashMap<String, Object> temp;
// total number of rows in the ListView
int noOfPlayers = names.length;
// now populate the ArrayList players
for (int i = 0; i < noOfPlayers; i++) {
temp = new HashMap<String, Object>();
temp.put("name", names[i]);
temp.put("team", teams[i]);
temp.put("photo", photos[i]);
temp.put("id", id[i]);
// add the row to the ArrayList
originalValues.add(temp);
}
// searchResults=OriginalValues initially
searchResults = new ArrayList<HashMap<String, Object>>(originalValues);
final CustomAdapter adapter = new CustomAdapter(this, R.layout.players, searchResults);
// finally,set the adapter to the default ListView
playersListView.setAdapter(adapter);
searchBox.addTextChangedListener(new TextWatcher() {
public void onTextChanged(CharSequence s, int start, int before, int count) {
// get the text in the EditText
String searchString = searchBox.getText().toString();
int textLength = searchString.length();
// clear the initial data set
searchResults.clear();
for (int i = 0; i < originalValues.size(); i++) {
String playerName = originalValues.get(i).get("name").toString();
if (textLength <= playerName.length()) {
// compare the String in EditText with Names in the
// ArrayList
if (searchString.equalsIgnoreCase(playerName.substring(0, textLength)))
searchResults.add(originalValues.get(i));
}
}
adapter.notifyDataSetChanged();
}
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
public void afterTextChanged(Editable s) {
}
});
// listening to single list item on click
playersListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
int pos=Integer.ParseInt(searchResults.get(position).get("id").toString());
switch (pos) {
case 0:
Intent newActivity = new Intent(TeamsList.this, Barca.class);
startActivity(newActivity);
break;
case 1:
etc...
}
}
}
});
}
自定义适配器类：
private class CustomAdapter extends ArrayAdapter<HashMap<String, Object>> {
public CustomAdapter(Context context, int textViewResourceId, ArrayList<HashMap<String, Object>> Strings) {
// let android do the initializing :)
super(context, textViewResourceId, Strings);
}
// class for caching the views in a row
private class ViewHolder {
ImageView photo;
TextView name, team;
}
ViewHolder viewHolder;
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = inflater.inflate(R.layout.players, null);
viewHolder = new ViewHolder();
// cache the views
viewHolder.photo = (ImageView) convertView.findViewById(R.id.photo);
viewHolder.name = (TextView) convertView.findViewById(R.id.name);
viewHolder.team = (TextView) convertView.findViewById(R.id.team);
//Take one textview in listview design named id
viewHolder.id = (TextView) convertView.findViewById(R.id.id);
// link the cached views to the convert view
convertView.setTag(viewHolder);
} else
viewHolder = (ViewHolder) convertView.getTag();
int photoId = (Integer) searchResults.get(position).get("photo");
// set the data to be displayed
viewHolder.photo.setImageDrawable(getResources().getDrawable(photoId));
viewHolder.name.setText(searchResults.get(position).get("name").toString());
viewHolder.team.setText(searchResults.get(position).get("team").toString());
viewHolder.id.setText(searchResults.get(position).get("id").toString());
// return the view to be displayed
return convertView;
}
}
}

我认为你无法在listview项目点击上找到正确的位置。所以你可以使用一个textview和visibility =＆＃34; Gone＆＃34;并在每行的textview中插入位置。现在，您可以轻松访问位置，同时单击具有textview值的项目，该值显示完美位置。希望它有效。感谢名单

问题在于适配器已填充一次，但搜索结果会被搜索到的项目覆盖，因此点击它会引用列表的原始项目而不是过滤列表一次，因此我们必须使用过滤后的列表＆＃39 ;位置而不是原来的位置，我也遇到了这个问题，试试这个：
在 listView.setOnItemClickListener
中playersListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,int position, long id) {
//Object objFilteredItem = parent.getItemAtPosition(position);
//String a = searchResults.get(position);
switch (Integer.parseInt((String) adapter.getItem(position))) {
case 0:..
Intent newActivity = new Intent(TeamsList.this,Barca.class);
startActivity(newActivity);
break;
case 1:
etc...
break;
}
}
});

从我之前回答的问题here开始，您必须覆盖getItem(position)中的CustomAdapter方法。您正在正确设置onItemClick，但列表适配器不知道它从getItem(position)获得了什么。
编辑（详情）：您需要在自定义适配器中添加类似的内容 -
@Override
public Object getItem(int position) {
return list.get(position);
}
您的自定义适配器中应该已经有list。如果没有，您可以向CustomAdapter添加列表参考：
private ArrayList<HashMap<String, Object>> list;
然后使用Group活动中的setter设置它：
customAdapter.setList(searchResults);
