以前的片段不隱藏爲什麼？

Question

我想添加片段，我設置了前一個背景#ffffff佈局當我去下一個片段時隱藏，但是在之前片段中的項目在下一個片段中工作時，片段不能隱藏原因？

這是我的代碼

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 

      if(isSearchHappened){ 
       android.support.v4.app.FragmentTransaction transection=getActivity().getSupportFragmentManager().beginTransaction(); 
       transection.hide(WorkOrderFragment.this); 
       DeliveryProcessFragment deliveryProcessFragment=new DeliveryProcessFragment(); 
       deliveryProcessFragment.jobBeans = searchArayList.get(position); 
       transection.add(R.id.frame, deliveryProcessFragment); 
       transection.commit(); 
      }else { 
       android.support.v4.app.FragmentTransaction transection=getActivity().getSupportFragmentManager().beginTransaction(); 
       transection.hide(WorkOrderFragment.this); 
       DeliveryProcessFragment deliveryProcessFragment=new DeliveryProcessFragment(); 
       deliveryProcessFragment.jobBeans = arrayList.get(position); 
       transection.add(R.id.frame, deliveryProcessFragment); 
       transection.commit(); 
      } 


     } 
    });

這可能會幫助你。

FragmentManagerfragmentManager=getFragmentManager(); 
    FragmentTransactionfragmentTransaction=fragmentManager.beginTransaction(); 
    myFrag=newMyFrag(); 
    myFrag.setSpecialText("Fragtime:"+System.currentTimeMillis()); 
    myFragList.add(myFrag); 
    fragmentTransaction.add(R.id.myFrame,myFrag); 
    fragmentTransaction.commit(); 
} 
else { 
    if((myFragList.size()-1)>=0){ 
    FragmentManagerfragmentManager=getFragmentManager(); 
    FragmentTransactionfragmentTransaction=fragmentManager.beginTransaction(); 
    MyFraglastFrag=myFragList.get(myFragList.size()-1); 
    fragmentTransaction.remove(lastFrag); 
    myFragList.remove(lastFrag); 
    fragmentTransaction.commit(); 
    } 
}
