我对搜索客户names.It一个编辑文本是一个多线编辑文本field.I想给最终用户在一个单一的编辑文本添加多个用户的能力。
因此，在头名最终用户类型从下拉菜单中选择用户，并按下回车添加新用户。 我能够搜索第一个用户，但无法搜索下一个用户。
以下是我使用的代码： -
public TextWatcher searchTextWatcher = new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}
@Override
public void onTextChanged(CharSequence query, int start, int before, int count) {
mRecyclerView.setVisibility(View.VISIBLE);
query = query.toString().toLowerCase();
final List<String> filteredList = new ArrayList<>();
for (int i = 0; i < list.size(); i++) {
String text = list.get(i).toLowerCase();
if (query.length()>0 && query.subSequence(query.length()-1, query.length()).toString().equalsIgnoreCase("\n"))
{
String multiLines = query.toString();
String[] names;
String delimiter ="\n";
names = multiLines.split(delimiter);
ArrayList guest_info = new ArrayList(Arrays.asList(names));
ListIterator<String> it = guest_info.listIterator();
while (it.hasNext())
{
String guest = it.next();
Log.d("Guest ", guest);
if (text.toLowerCase().contains(guest))
{
filteredList.add(list.get(i));
}
}
}else
if(text.contains(query))
{
filteredList.add(list.get(i));
}
}
mRecyclerView.setLayoutManager(new LinearLayoutManager(BookingActivity.this));
guestAdapter = new GuestAdapter(filteredList, getApplicationContext(),BookingActivity.this);
mRecyclerView.setAdapter(guestAdapter);
guestAdapter.notifyDataSetChanged(); // data set changed
}
@Override
public void afterTextChanged(Editable editable) {
String name = editable.toString();
if (name.equals(""))
{
mRecyclerView.setVisibility(View.GONE);
}
}
};
我是新来的编程所以任何帮助或建议是appreciated.Thank你。
