我的應用程序古怪行爲，我用我的活動佈局內的FrameLayout膨脹片段類，像這樣：怪異片段交易行爲
if (mapFragment == null) {
mapFragment = MapFragment.newInstance();
addFragment(mapFragment, null, MapFragment.class.getCanonicalName(), false, MainActivity.this);
} else {
addFragment(mapFragment, null, MapFragment.class.getCanonicalName(), false, MainActivity.this);
}
奇怪的是用戶運行這個第一次代碼通過點擊一個按鈕我的整個活動重新啓動，邏輯上不再顯示片段。這裏的addFragment方法：
void addFragment(Fragment frag, Bundle bundle, String backstack,
boolean forceReplace, FragmentActivity _activity) {
Log.e("Addfragment Method", "Fragment Added");
FragmentManager fm = _activity.getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(getRes());
FragmentTransaction ft = fm.beginTransaction();
if (bundle != null) {
frag.setArguments(bundle);
}
if (fragment != null || forceReplace) {
ft.replace(getRes(), frag, backstack);
ft.addToBackStack(backstack);
Log.e("replaced","fragment");
} else {
ft.add(getRes(), frag, backstack);
ft.addToBackStack(backstack);
Log.e("created","fragment");
}
ft.commitAllowingStateLoss();
}
這裏是片段onCreateView方法

Bundle savedInstanceState) {
// Inflate the layout for this fragment
Utils.sendTrackerDetails(this.getClass().getSimpleName());

我沒有看到任何可能是錯誤的，但可能發佈更多的信息 - XML，事件方法，片段的oncreate/oncreateview。 'commitAllowingStateLoss（）'有點擔心整體架構。 – zec
我會編輯發佈的代碼，但真正令人困惑的事實是，第二次點擊正常工作 我試過使用commit（）和commitNow（）相同的結果！ –
