感谢您的帮助。我不知道为什么它不起作用。我添加了以下功能来搜索用户。我调试它，它似乎停留在过滤器（argo）功能。我的代码如下。 logcat错误中没有任何内容。感谢您的帮助。

答案 0 :(得分：0)
我有类似的代码可能很有用：
在这段代码中，我们有几个类：
第一个：在列表中搜索并在列表视图中显示结果的搜索类
第二：准备列表视图的CustomAdapter
第三：主要在搜索类中调用搜索功能
public class Search
{
android.content.Context context;
CustomAdaptor tempAdptr;
CustomAdaptor adptr;
android.widget.ListView lstContact;
java.util.ArrayList<MyObject> arrMyObject;
public SearchContact(android.content.Context con , CustomAdaptor adp , android.widget.ListView lst )
{
context = con;
arrMyObject = new java.util.ArrayList<MyObject>();
tempAdptr = new CustomAdaptor(context, R.layout.contact_row, arrMyObject);
adptr = adp;
lstContact = lst;
}
public void Search(String strSearch)
{
lstContact.setAdapter(tempAdptr);
if(strSearch.equals(""))
{
lstContact.setAdapter(adptr);
return ;
}
arrMyObject.removeAll(arrMyObject) ;
for(int i = 0 ; i < MainActivity.GetArrMyObject().size() ; i++)
{
if(arrlist.get(i).contains(strSearch))
{
//Add item to your list
}
}
tempAdptr.notifyDataSetChanged();
}
}
//------------------------------------------------------------------------------------
public class CustomAdaptor extends ArrayAdapter<MyObject> {
android.content.Context context;
int resId;
java.util.ArrayList<MyObject> arrData;
public ContactAdaptor(android.content.Context ac, int resource , java.util.ArrayList<MyObject> data ) {
super(ac, resource, data);
context = ac;
resId = resource;
arrData = data;
}
@Override
public android.view.View getView(final int position,android.view.View convertView, android.view.ViewGroup parent)
{
try
{
MyObject member = arrData.get(position);
android.view.LayoutInflater inflater = (LayoutInflater) context.getSystemService(android.content.Context.LAYOUT_INFLATER_SERVICE);
android.view.View Row =inflater.inflate(resId, parent , false);
// Set Your XML file
return Row;
}
catch (Exception e)
{
return null;
}
}
}
现在您可以在main中使用此代码：
SearchContact srchContact = new SearchContact(context, adptr, arraylist);
srchContact.Search(YourObject);
