Android适配器过滤

Question

我是Android的新手我从Mysql创建了一个数据列表，当我过滤Listview时它工作正常但是当我点击过滤的项目时，它获取了错误的对象Id但我想要的是当我点击过滤的项目时它应该显示正确的项目ID。

这是代码：

package com.example.akbari.test;

import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;

import android.widget.AdapterView;
import android.widget.EditText;
import android.widget.ListView;

                // now we can use the regular ListView API for filtering:

Answer 1

insted of

  ArrayList<Clients> filtered = new ArrayList<Clients>();

使用

  list= new ArrayList<Clients>();
