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 {@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {return inflater.inflate(R.layout.list, null);}@Overridepublic 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);}@Overridepublic 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 fragmentprivate 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();}
