我有一个ListView，我覆盖了getView方法，该方法使用以下代码正确填充。如果我使用'adapter.getfilter（）'，它不会更新列表视图，尽管在适配器中它已过滤，并且在NEXT过滤器完成时通过'out（）'正确显示，在编辑框中输入文本。任何想法如何在我重写getView和过滤器影响适配器的同时而不是下次在编辑框中输入文本时如何启用过滤？覆盖getView时启用筛选
final ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,
android.R.layout.activity_list_item,stringArray)
{ @Override
public View getView(int position, View convertView, ViewGroup parent)
{View row= super.getView(position, convertView, parent);
View row=convertView;
if(position==0){
row = mLayoutInflater.inflate(R.layout.list_header, null);
final TextView sectionView = (TextView) row.findViewById(R.id.list_item_section_text);
sectionView.setText(myList.get(position));
}
else
{row = mLayoutInflater.inflate(R.layout.list_item, null);
final TextView sectionView = (TextView) row.findViewById(R.id.list_item_entry_title);
sectionView.setText(myList.get(position));}
return row;}});
lv.setAdapter(adapter);
for (int i = 0; i < adapter.getCount(); i++) {//displaying properly
pr("adapter list"+adapter.getItem(i));
}
myFilter.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) { }
public void beforeTextChanged(CharSequence s, int start, int count, int after) {}
public void onTextChanged(CharSequence s, int start, int before, int count) {
adapter.getFilter().filter(s);
adapter.notifyDataSetChanged();
for (int i = 0; i < adapter.getCount(); i++) {
pr("adapter list before "+ (adapter.getItem(i)));//printing properly but not
//updated in listview ,sometimes it just displays first few ,even if it should not be
//in filtered result after filtering.
} } });
