Java 在android的自定义列表视图中仅搜索特定值的结果?
我使用的是自定义列表视图,我想搜索一个特定的值。现在我想我的代码搜索的是与输入的文本匹配的任何内容。我只想搜索文档号。 下面是我的代码Java 在android的自定义列表视图中仅搜索特定值的结果?,java,android,android-arrayadapter,Java,Android,Android Arrayadapter,我使用的是自定义列表视图,我想搜索一个特定的值。现在我想我的代码搜索的是与输入的文本匹配的任何内容。我只想搜索文档号。 下面是我的代码 public void showJson(String json) { final Context billsctx = getActivity(); ParseBills pb = new ParseBills(json); pb.parseJSON(); bl = new BillsCu

这是我的适配器代码
public class BillsCustomList extends ArrayAdapter<String>
{
private String[] doc_no;
private String[]date;
private String[] cust_name;
private String[] cust_number;
private String[] item_count;
private String[]total_wt;
private String[]total;
private String[]balance;
private String[]bill_type;
private Activity context;
public BillsCustomList(Activity context, String[] doc_no, String[] date, String[] cust_name,String[] cust_number,String[] item_count,String[] total_wt,String[] total,String[] balance,String[] bill_type)
{
super(context, R.layout.bills_list_view, doc_no);
this.context =context;
this.doc_no=doc_no;
this.date = date;
this.cust_name = cust_name;
this.cust_number = cust_number;
this.item_count= item_count;
this.total_wt = total_wt;
this.total = total;
this.balance = balance;
this.bill_type = bill_type;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = context.getLayoutInflater();
View listViewItem = inflater.inflate(R.layout.bills_list_view, null, true);
TextView textViewDocno = (TextView) listViewItem.findViewById(R.id.textViewInvNo);
TextView textViewDt = (TextView) listViewItem.findViewById(R.id.textViewDt);
TextView textViewName = (TextView) listViewItem.findViewById(R.id.textViewName);
TextView textViewNumber = (TextView) listViewItem.findViewById(R.id.textViewNumber);
TextView textViewCount = (TextView) listViewItem.findViewById(R.id.textViewCount);

TextView textViewTot = (TextView) listViewItem.findViewById(R.id.textViewTot);
TextView textViewBal = (TextView) listViewItem.findViewById(R.id.textViewBalanace);
TextView textViewBt = (TextView) listViewItem.findViewById(R.id.textViewBt);
textViewDocno.setText(doc_no[position]);
textViewDt.setText(date[position]);

textViewTotwt.setText(total_wt[position]);
textViewTot.setText(total[position]);
textViewBal.setText(balance[position]);
textViewBt.setText(bill_type[position]);
return listViewItem;
}
}
公共类BillsCustomList扩展了ArrayAdapter

私有字符串[]文档编号;
私有字符串[]日期;
私有字符串[]客户名称;
私有字符串[]客户编号;
私有字符串[]项计数;
私有字符串[]总重量;
私有字符串[]总计;
私人字符串[]余额;
专用字符串[]票据类型;
私人活动语境;
公共账单列表(活动上下文,字符串[]单据号,字符串[]日期,字符串[]客户名称,字符串[]客户编号,字符串[]项目计数,字符串[]总计,字符串[]余额,字符串[]账单类型)
{
super(上下文、右布局、账单列表视图、单据号);
this.context=上下文;
this.doc\u no=doc\u no;

}

任何建议或帮助都将不胜感激。谢谢。尝试使用以下自定义过滤器:
@Override
public Filter getFilter() {
Filter filter=new Filter() {
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results=new FilterResults();
if(constraint!=null)
{
places=getPredictions(constraint.toString());
if(places!=null)
{
results.values=places;
results.count=places.size();
}
}
return results;
}
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
if (results != null && results.count > 0) {
// The API returned at least one result, update the data.
notifyDataSetChanged();
} else {
// The API did not return any results, invalidate the data set.
notifyDataSetInvalidated();
}
}
};
return filter;
}

refreshFragment()做什么?@user3295583 refreshFragment()刷新列表视图。refreshFragment()做什么?@user3295583 refreshFragment()刷新列表视图。
