我有一個列表視圖獲取過濾頂部的編輯文本。但是當我點擊搜索項目時，我得到的另一個項目被選中的結果。還有一些存儲在我的數組中的數據，這些數據在列表視圖中不可見，也會返回錯誤的數據。 在搜索C時，您將得到的結果過濾爲C.But點擊它的結果就像位置不會改變其他數據，但使用原始的ArrayList適配器位置。在列表視圖中的搜索過濾器返回錯誤的值上的項目點擊
任何幫助將不勝感激。
我的項目：
public class Leave_master_items {
public String leave_id;
public String leave_Name;
public String is_hourly;
public Leave_master_items(String leave_Name) {
this.leave_Name = leave_Name;
}
public String getLeave_id() {
return leave_id;
}
public void setLeave_id(String leave_id) {
this.leave_id = leave_id;
}
public String getLeave_Name() {
return leave_Name;
}
public void setLeave_Name(String leave_Name) {
this.leave_Name = leave_Name;
}
public String getIs_hourly() {
return is_hourly;
}
public void setIs_hourly(String is_hourly) {
this.is_hourly = is_hourly;
}
}

其BEC返回0 ause你正在做notifydatasetchanged（），所以列表被改變 – Avinash
