我宣布了
HeaderListView list;
我尝试实现搜索栏。一切都很好，但这条线显示错误。我没有使用listview我用过列表 这是行
list.setTextFilterEnabled(true);
我必须在这做什么？..
提前致谢

答案 0 :(得分：1)
正如official documentation所指出的那样，你的适配器应该实现Filterable接口，只能使用list.setTextFilterEnabled（true）。你的SectionAdapter是否实现了它？如果没有，请尝试这样做。

我正在使用编辑文字，希望这会对你有帮助！
inputSearch = (EditText)findViewById(R.id.inputSearch);
ListView lv = getListView();
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
youractivityname.this.adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2,
int arg3) {
}
@Override
public void afterTextChanged(Editable s) {
}
});

使用Edittext从Listview过滤数据。 这里我在我的Adapter类和我的活动中做了什么来过滤数据：
适配器类
public class FindAProfessorAdapter extends ArrayAdapter<Data> implements
Filterable {
int layoutResourceId;
LayoutInflater mInflater;
ArrayList<Data> list;
ArrayList<Data> secondlist;
Context context;
Data data;
public FindAProfessorAdapter(Context context, int layoutResourceId,
ArrayList<Data> data) {
super(context, layoutResourceId, data);
mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
list = new ArrayList<Data>();
secondlist = new ArrayList<Data>();
secondlist.addAll(data);
list.addAll(secondlist);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.list = data;
getFilter();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
final ViewHolder holder;
if (convertView == null) {
mInflater = LayoutInflater.from(context);
convertView = mInflater.inflate(layoutResourceId, parent, false);
holder = new ViewHolder();
holder.textView = (TextView) convertView
.findViewById(R.id.findproname);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.textView.setText(list.get(position).getName());
return convertView;
}
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint,
FilterResults results) {
list = (ArrayList<Data>) results.values;
notifyDataSetChanged();
clear();
for (int i = 0; i < list.size(); i++) {
add(list.get(i));
notifyDataSetChanged();
}
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults filterResults = new FilterResults();
ArrayList<Data> FilteredArrList = new ArrayList<Data>();
if (secondlist == null) {
secondlist = new ArrayList<Data>(list);
}
if (constraint != null && constraint.toString().length() != 0) {
constraint = constraint.toString().toLowerCase(
Locale.getDefault());
for (int i = 0; i < list.size(); i++) {
Data name = secondlist.get(i);
if (name.getName().toLowerCase(Locale.getDefault())
.contains(constraint)) {
FilteredArrList.add(name);
}
}
filterResults.count = FilteredArrList.size();
filterResults.values = FilteredArrList;
} else {
synchronized (this) {
filterResults.count = secondlist.size();
filterResults.values = secondlist;
}
}
return filterResults;
}
};
return filter;
}
class ViewHolder {
TextView textView;
}
}
在我的活动中：
editText = (EditText) view.findViewById(R.id.findaprofessor);
editText.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
adapter.getFilter().filter(s.toString());
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
@Override
public void afterTextChanged(Editable s) {
}
});
您需要将此作为示例并根据此编辑适配器。
