这段代码完全有效，代码是：

这是MainActivity.java

这是MyListAdapter.java

     continentList.add(nContinent);
    }
   }
  }

  Log.v("MyListAdapter", String.valueOf(continentList.size()));
  notifyDataSetChanged();

 }

}

这是Continent.java 

package com.example.tesskian;

import java.util.ArrayList;

public class continent {

 private String name;
 private ArrayList<country> countryList = new ArrayList<country>();

 public continent(String name, ArrayList<country> countryList) {
  super();
  this.name = name;
  this.countryList = countryList;
 }
 public String getName() {
  return name;
 }
 public void setName(String name) {
  this.name = name;
 }
 public ArrayList<country> getCountryList() {
  return countryList;
 }
 public void setCountryList(ArrayList<country> countryList) {
  this.countryList = countryList;
 };


}

这是Counter.java 

package com.example.tesskian;

public class country {

     private String code = "";
     private String name = "";
     private int population = 0;

     public country(String code) {
      super();
      this.code = code;
      this.name = name;
      this.population = population;
     }

     public String getCode() {
      return code;
     }
     public void setCode(String code) {
      this.code = code;
     }
     public String getName() {
      return name;
     }
     public void setName(String name) {
      this.name = name;
     }
     public int getPopulation() {
      return population;
     }
     public void setPopulation(int population) {
      this.population = population;
     }

    }

它正在工作但是当我开始用searchview过滤它时，问题就来了。活动已经开始，但它与我搜索的活动不匹配。例如，我正在寻找＆＃34;示例＆＃34;但是，如果我点击它显示第一个活动＆＃34; cont.class＆＃34;。有人能帮助我吗？
