所以我試圖在我的應用程序實現側導航，我似乎無法找到一種方法來實現它我想要的方式。我已經看過多個例子，並且我從korovyansk中找到了一個非常適合我想要的模型的例子，但是當按下菜單項時，我似乎無法在活動之間切換。我通過調整「onListItemClick」並開始一個新的Intent來切換活動，但是當活動開始時，它會佔用整個屏幕並重疊側邊欄動畫，從而使其看起來馬虎。我希望它在右側佈局中加載活動，而側邊導航欄則關閉到左側的類似Facebook。有沒有簡單的方法可以做到這一點？實施側導航切換活動

編輯： 確定試圖避免這種情況，但現在似乎不可避免。所以即時嘗試使用FragmentTransaction。
在onListItemClick下MenuFragment.java我：
@Override
public void onListItemClick(ListView l, View v, int position, long id) {
super.onListItemClick(l, v, position, id);
((MenuActivity)getActivity()).getSlideoutHelper().close();
Fragment dummy = new Dummy();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.inner_content, dummy);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
}
Dummy.java
public class Dummy extends Fragment{
View blag;
@TargetApi(11)
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
blag = inflater.inflate(R.layout.samplex, container, false);
//(samplex is same as sample.xml just different logo
return blag;
}
}
但是它現在與錯誤消息崩潰：11月3日至22日：54：24.469：E/AndroidRuntime（31673）：java.lang.IllegalArgumentException：沒有找到id爲0x7f060000的片段虛擬視圖{42540328＃1 id = 0x7f060000} 對此的任何想法。
謝謝，請你看看編輯，看看你能幫我嗎？ – user1823974 2013-03-22 16:05:10
