实现侧边导航以在活动之间切换

【中文标题】实现侧边导航以在活动之间切换【英文标题】:Implementing Side Navigation to switch between activities 【发布时间】:2013-03-12 11:28:02 【问题描述】:所以我试图在我的应用程序中实现侧边导航,但我似乎无法找到一种方法来按照我想要的方式实现它。我看过多个示例,我从科罗维扬斯克遇到了这个,它非常符合我想要的模式,但是当按下菜单项时,我似乎无法在活动之间切换。我通过调整“onListItemClick”并启动新的 Intent 让应用程序在活动之间切换,但是当活动启动时,它会占据整个屏幕并与侧边栏动画重叠,因此看起来很草率。我希望它在右侧布局中加载活动,而侧面导航靠近左侧,有点像 facebook。有什么简单的方法可以做到这一点?

编辑: 好的试图避免这种情况,但现在似乎不可避免。所以我尝试使用 FragmentTransaction。
在 onListItemClick 下的 MenuFragment.java 我有:
@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;
但是它现在崩溃并出现错误消息:03-22 11:54:24.469: E/AndroidRuntime(31673): java.lang.IllegalArgumentException: No view found for id 0x7f060000 for fragment Dummy42540328 #1 id=0x7f060000 知道为什么会这样。
【问题讨论】:
【参考方案1】:这是一个简单的答案:
不要使用活动!
只有一个 Activity 的布局包含 R.id.menu(菜单)和 R.id.content(示例名称),然后您将使用 Fragment 和 FragmentTransaction 以及 FragmentManager 来操作 R.id 中的片段.content(虽然菜单会很好地动画)。
此外,我建议您将这个库用于菜单:https://github.com/jfeinstein10/SlidingMenu 我以前用过它,它真的很好用。
编码愉快。
