共享偏好不相似(shared preference not similar)

 我有两个修改共享首选项文件的onclick操作： 
 
int value = counters.getInt("wcounter", 0);
wcounter = value;
wcounter++;
Editor editor = counters.edit();
editor.putInt("wcounter", wcounter);
editor.commit();
 
 和 
 
int value = counters.getInt("wcounter", 0);
wcounter = value;
wcounter--;
Editor editor = counters.edit();
editor.putInt("wcounter", wcounter);
editor.commit();
 
 但是当第一个被重新执行时，它需要它的旧值。 

I have two onclick actions that modifies a shared preference file : 
 
int value = counters.getInt("wcounter", 0);
wcounter = value;
wcounter++;
Editor editor = counters.edit();
editor.putInt("wcounter", wcounter);
editor.commit();
 
and 
 
int value = counters.getInt("wcounter", 0);
wcounter = value;
wcounter--;
Editor editor = counters.edit();
editor.putInt("wcounter", wcounter);
editor.commit();
 
but when the first one is re executed it takes it's old value.
