我正在尝试将 SlidingMenu 包含在片段中。我之所以想在片段中放置一个 SlidingMenu 是因为我的 viewPager 的一个页面将显示它。只是对我如何扩展片段感到困惑，因为其中一个示例扩展了SlidingFragmentActivity。
public class Activity A extends SlidingFragmentActivity {}
我一直在尝试这样，
public class ResponsiveUIActivityE extends SherlockFragment{
View rootView;
private Fragment mContent;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
SlidingFragmentActivity2 sl = new SlidingFragmentActivity2();
getActivity().setTitle("R.string.responsive_ui");
LayoutInflater vi = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rootView = vi.inflate(R.layout.two_fragments, null, false);
// check if the content frame contains the menu frame
if (rootView.findViewById(R.layout.two_fragments) == null) {
//sl.setBehindContentView(R.layout.two_fragments);
sl.getSlidingMenu().setSlidingEnabled(true);
sl.getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);
// show home as up so we can toggle
} else {
}
// set the Above View Fragment
if (savedInstanceState != null){
mContent = getChildFragmentManager().getFragment(savedInstanceState, "mContent");
if (mContent == null)
mContent = new BirdGridFragment(0);
getChildFragmentManager()
.beginTransaction()
.replace(R.id.content_frame, mContent)
.commit();
// set the Behind View Fragment
getChildFragmentManager()
.beginTransaction()
.replace(R.id.menu_frame, new BirdMenuFragment())
.commit();
// customize thse SlidingMenu
SlidingMenu sm = sl.getSlidingMenu();
sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);
sm.setShadowWidthRes(R.dimen.shadow_width);
sm.setShadowDrawable(R.drawable.shadow);
sm.setBehindScrollScale(0.25f);
sm.setFadeDegree(0.25f);
}
return rootView;
}
}
