排序列表視圖時未調用比較方法

Question

我有一個自定義的ArrayAdapter，並且在某些時候我調用super.sort(new MyComparatorB(orderType, context));，但在MyComparatorB中實現的比較（DeviceB lhs，DeviceB rhs）方法永遠不會被調用，並且下一條指令正常執行。問題是什麼？

UPDATE

MyComparatorB

public class MyComparatorB implements Comparator<DeviceB> { 

private String orderType; 
private Context cont; 

public MyComparatorB(String type, Context cont) { 

    this.orderType = type; 
    this.cont = cont; 


} 

public int compare(DeviceB lhs, DeviceB rhs) { 

    int res = 0; 
    if (orderType.equals(cont.getString(R.string.alpha_text))) { 
     res = (lhs.getName()).compareTo(rhs.getName()); 
    } 
    else if (orderType.equals(cont.getString(R.string.lastAct_text))) { 
     res = (rhs.getTime().getTime()).compareTo(lhs.getTime().getTime()); 
    } 
    return res; 
} 

} 

DeviceBAdapter

public class DeviceBAdapter extends ArrayAdapter<DeviceB> implements Filterable { 

private Context context; 
private ArrayList<DeviceB> allDev; 
private ArrayList<DeviceB> dev; 
//... 

public DeviceBAdapter(Context context, BliveAPI blapi) { 
    super(context, R.layout.sensor_row_state_list); 
    this.context = context; 
    this.bliveapi = blapi; 
    this.allDev = allDevToArrayList(); 
    this.dev = new ArrayList<DeviceB>(allDev); 
    notifyDataSetChanged(); 
} 

@Override 
public void notifyDataSetChanged() { 
    super.notifyDataSetChanged(); 
} 


public void sort(String s) { 

    super.sort(new MyComparatorB(s,context)); 
    notifyDataSetChanged(); 
} 
//... 
} 

MyActivity

//... 
myDevAdapter.sort(getString(R.string.alpha_text)); 
//...

故障排除：

嘗試增加@Override前public int compare(DeviceB lhs, DeviceB rhs)

這應該踢警告/錯誤，如果你不INFACT覆蓋在比較的比較方法
