NullPointerException异常android系统碎片经理

Question

我有一个代码来重新创建地图，如：

public void onDestroyView() { 
     super.onDestroyView();  

     if (this.f != null 
       && getFragmentManager().findFragmentById(
         this.f.getId()) != null) { 
      Log.i("DESTROY VIEW MAP", "MAP!!!!!!!!!!!"+f); 
      myFragmentManagerSupport.beginTransaction().remove(this.f).commit(); 
      Log.i("DESTROY VIEW MAP 222222222222222", "MAP!!!!!!!!!!!"+f); 
      // this.f = null; 
      Log.i("DESTROY VIEW MAP 333333333333333333", "MAP!!!!!!!!!!!"+f); 
     } 

    } 

，但我有力闭合，当我去从本节后面。我在代码中有错误

myFragmentManagerSupport.beginTransaction().remove(this.f).commit(); 

当我评论代码时，没有问题。

任何人都可以帮助我吗？

使用相同的fragmentManager对象 public void onDestroyView（）{ super.onDestroyView（）;

if (this.f != null 
      && myFragmentManagerSupport().findFragmentById(
        this.f.getId()) != null) { 
     Log.i("DESTROY VIEW MAP", "MAP!!!!!!!!!!!"+f); 
     myFragmentManagerSupport.beginTransaction().remove(this.f).commit(); 
     Log.i("DESTROY VIEW MAP 222222222222222", "MAP!!!!!!!!!!!"+f); 
     // this.f = null; 
     Log.i("DESTROY VIEW MAP 333333333333333333", "MAP!!!!!!!!!!!"+f); 
    } 

}
