package com.jeremyfeinstein.slidingmenu.example.fragments;import android.os.Bundle;import android.support.v4.app.Fragment;import android.support.v4.app.ListFragment;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.ArrayAdapter;import android.widget.ListView;import com.jeremyfeinstein.slidingmenu.example.R;public class ColorMenuFragment extends ListFragment {	@Override	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {		return inflater.inflate(R.layout.list, null);	}	@Override	public void onActivityCreated(Bundle savedInstanceState) {		super.onActivityCreated(savedInstanceState);		String[] colors = getResources().getStringArray(R.array.color_names);		ArrayAdapter<String> colorAdapter = new ArrayAdapter<String>(getActivity(), 				android.R.layout.simple_list_item_1, android.R.id.text1, colors);		setListAdapter(colorAdapter);	}	@Override	public void onListItemClick(ListView lv, View v, int position, long id) {		Fragment newContent = null;		switch (position) {		case 0:			newContent = new ColorFragment(R.color.red);			break;		case 1:			newContent = new ColorFragment(R.color.green);			break;		case 2:			newContent = new ColorFragment(R.color.blue);			break;		case 3:			newContent = new ColorFragment(android.R.color.white);			break;		case 4:			newContent = new ColorFragment(android.R.color.black);			break;		}		if (newContent != null)			switchFragment(newContent);	}	// the meat of switching the above fragment	private void switchFragment(Fragment fragment) {		if (getActivity() == null)			return;				if (getActivity() instanceof FragmentChangeActivity) {			FragmentChangeActivity fca = (FragmentChangeActivity) getActivity();			fca.switchContent(fragment);		} else if (getActivity() instanceof ResponsiveUIActivity) {			ResponsiveUIActivity ra = (ResponsiveUIActivity) getActivity();			ra.switchContent(fragment);		}	}}

这个例子主要介绍了，如何实现主界面fragmen的切换

1、在侧边栏的Fragment里面

private void switchFragment(Fragment fragment) {		if (getActivity() == null)			return;				if (getActivity() instanceof FragmentChangeActivity) {			FragmentChangeActivity fca = (FragmentChangeActivity) getActivity();			fca.switchContent(fragment);		} else if (getActivity() instanceof ResponsiveUIActivity) {			ResponsiveUIActivity ra = (ResponsiveUIActivity) getActivity();			ra.switchContent(fragment);		}	}

调用上层activity的switchContent方法

public void switchContent(Fragment fragment) {		mContent = fragment;		getSupportFragmentManager()		.beginTransaction()		.replace(R.id.content_frame, fragment)		.commit();		getSlidingMenu().showContent();	}
