Android在列表视图中隐藏行

In my android application I am taking contacts from contact list and storing in list arrays.this contact list I am showing in my app for selection..In contact list normally users may store atm pins, pass book number etc... so i want to avoid storing of any number below 10 digits. Here the problem is I am storing contacts name to one list array and contact number to another list array. If I am removing numbers only..then it is difficult for me to remove the corresponding contact names..I am giving my code below.. can anyone help me with a solutionIn my android application I am taking contacts
