我有一个列表视图，它根据文本更改显示数据。但是我得到两次显示相同的数据。例如，如果我的列表包含一个“apple”，则列表将包含两个apple。即两次相同的条目。
这是我的代码： -
private void showDocno(String response) {
ParseAdvOpen pao = new ParseAdvOpen(response);
pao.parseJSON();
List<Map<String, String>> dn_info = new ArrayList<Map<String, String>>();
Map<String, String> dn_map;
int counts = ParseAdvOpen.adv_no.length;
for (int i = 0; i < counts; ++i) {
dn_map = new HashMap<>();
dn_map.put("doc_no", ParseAdvOpen.adv_no[i]);
dn_map.put("date", ParseAdvOpen.date[i]);
dn_map.put("cust_name", ParseAdvOpen.cust_name[i]);
dn_map.put("cust_number", ParseAdvOpen.cust_number[i]);
dn_map.put("item_count", ParseAdvOpen.item_count[i]);
dn_map.put("total", ParseAdvOpen.sum_total[i]);
dn_map.put("paid", ParseAdvOpen.paid[i]);
dn_info.add(dn_map);
}
dnAdapter = new SimpleAdapter(getActivity().getApplicationContext(), dn_info, R.layout.list_docno, new String[]{"doc_no", "cust_name", "cust_number"}, new int[]{R.id.textViewdn, R.id.customer_name, R.id.customer_mobile});
doc_list.setAdapter(dnAdapter);
Log.d("DNINFO", dn_info.toString());
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
doc_list.setVisibility(View.INVISIBLE);
advopen_list.setVisibility(View.VISIBLE);
searchlayout.setVisibility(View.GONE);
}
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
doc_list.setVisibility(View.VISIBLE);
}
@Override
public void afterTextChanged(Editable s) {
if (s.length() == 0) {
doc_list.setVisibility(View.INVISIBLE);
} else {
dnAdapter.getFilter().filter(s);
doc_list.setVisibility(View.VISIBLE);
}
}
});
doc_list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Map docSelected = (Map) dnAdapter.getItem(position);
String doc_number = (String) docSelected.get("doc_no");
String date = (String) docSelected.get("date");
String customerName = (String) docSelected.get("cust_name");
String mobileno = (String) docSelected.get("cust_number");
String icount = (String) docSelected.get("item_count");
String total = (String) docSelected.get("total");
String paid = (String) docSelected.get("paid");
Log.d("DOCUMENT SELECTED", doc_number + " " + customerName + " " + mobileno + " " + date);
advopen_list.setVisibility(View.GONE);
doc_list.setVisibility(View.GONE);
searchlayout.setVisibility(View.VISIBLE);
tv_docno.setText(doc_number);
tv_date.setText(date);
tv_name.setText(customerName);
tv_mobile.setText(mobileno);
tv_itemcount.setText(icount);
tv_tot.setText(total);
tv_paid.setText(paid);
}
});
}
这个方法在对mysql数据库的响应中被调用。
感谢任何帮助或建议。谢谢。
