首先感谢您的帮助。这对我来说是一个难题。
请我有一个包含 5 个片段的活动;在用户交互时,片段被交换。
我正在使用 ACL。
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
stackArray =new ArrayList<Integer>();
favQ =new ArrayList<Stock>();
tablet=true;
mBound = false;
fragmentActivity = this;
setContentView(R.layout.splashmain);
splashfragment =new splashFragment();
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.add(R.id.splashview,splashfragment);
fragmentTransaction.commit();
/*
other stuff....
*/
fragmentlista = new listafragment();
fragmentfavourites= new favouritesFragment() ;
worstbest = new WorstBest();
searchfragment = new searchFragment();
/*
other stuff....
*/
lt = mService.ritira();
worst=mService.ritiraWorst();
best=mService.ritiraBest();
favQ.clear();
favQ.addAll(mService.ritiraFav());
fragmentlista.prendiLista(lt);
worstbest.prendiListaWorst(worst);
worstbest.prendiListaBest(best);
if(favQ.size()>0)fragmentfavourites.prendiLista(favQ);
// --->>>>HERE THE SAME METHOD enableAll() WORKS!!! <---
// --->>>>HERE THE SAME METHOD enableAll() WORKS!!! <---
splashfragment.enableAll();
// --->>>>HERE THE SAME METHOD enableAll() WORKS!!! <---
// --->>>>HERE THE SAME METHOD enableAll() WORKS!!! <---
/*
other stuff....
*/
}
//Method invoked to setup the configuration of the screen is layoutSchermo(int conf)
public static void layoutSchermo(int conf){
//Check if it is a Tablet in Landscape mode or not
//if it finds v2 than we are on a LARGE screen, then we check ORIENTATIO
fragmentActivity.setContentView(R.layout.main);
View v2 =(View)fragmentActivity.findViewById(R.id.view2);
if(v2==null
&
fragmentActivity.getResources().getConfiguration().orientation==
Configuration.ORIENTATION_PORTRAIT)
tablet=false;
//Calls the screen configuration LIST
if(conf==LIST){
fragmentActivity.setContentView(R.layout.main);
FragmentManager fragmentManager = fragmentActivity.getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.remove(splashfragment);
fragmentTransaction.commit();
fragmentManager.executePendingTransactions();
//Remove old Fragment splashfragment
//At this point I expect the fragment splashfragment is destroyed
//OR NOT???
fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right);
if(!tablet){fragmentTransaction.replace(R.id.view1, fragmentlista);}
if(tablet){
fragmentTransaction.replace(R.id.view1, splashfragment);
fragmentTransaction.replace(R.id.view2,fragmentlista );
} fragmentTransaction.addToBackStack(null);
stack= fragmentTransaction.commit();
stackArray.add(stack);
//Brand new fragments added
// --->>>>HERE THE SAME METHOD enableAll() NOT WORKING!!! <---
// --->>>>HERE THE SAME METHOD enableAll() NOT WORKING!!! <---
splashfragment.enableAll();
}
------------
所以基本上会发生什么以及问题出在哪里:
问题出在方法上
layoutSchermo(int conf)
在方法 layoutSchermo(int conf) 中,
我分离了一个片段(splashfragment)并重新附加它(与另一个片段一起)。
我不清楚当我打电话时
remove(splashfragment)
实际上 Fragment 是否被销毁?
此外,每当新添加的 Fragment 是新的或旧的,为什么调用
splashfragment.enableAll();
有没有效果?
我希望它可以工作,无论是新的还是旧的片段!
请赐教!
谢谢毛里齐奥
