最近想做一个像facebook的侧边栏，但是刷新页面的功能无法实现

[kyle_nirvana]

最近做了一个仿 facebook 人人的android侧边栏程序

现在我希望点击左边的 侧边目录 然后只会改变我右边的 fragment里面的内容

请问如何实现

package com.example.slidingmenu.activity;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.StrictMode;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import com.example.slidingmenu.R;
import com.example.slidingmenu.fragment.LeftFragment;
import com.example.slidingmenu.fragment.PageFragment2;
import com.example.slidingmenu.fragment.ViewPageFragment;
import com.example.slidingmenu.fragment.ViewPageFragment.MyPageChangeListener;
import com.example.slidingmenu.view.SlidingMenu;

public class SlidingActivity extends FragmentActivity {
	SlidingMenu mSlidingMenu;
	LeftFragment leftFragment;

	ViewPageFragment viewPageFragment;
	public static int a=0;
	public static Context context;
	public Activity ac;
	@Override
	protected void onCreate(Bundle arg0) {
		super.onCreate(arg0);
		StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
		.permitAll().build();
        StrictMode.setThreadPolicy(policy);
		setContentView(R.layout.main);
		init();
		initListener();

	}

	private void init() {
		context=getApplicationContext();
		mSlidingMenu = (SlidingMenu) findViewById(R.id.slidingMenu);
		mSlidingMenu.setLeftView(getLayoutInflater().inflate(
				R.layout.left_frame, null));
		mSlidingMenu.setCenterView(getLayoutInflater().inflate(
				R.layout.center_frame, null));
		FragmentTransaction t = this.getSupportFragmentManager()
				.beginTransaction();
		leftFragment = new LeftFragment();
		t.replace(R.id.left_frame, leftFragment);
		viewPageFragment = new ViewPageFragment();
		t.replace(R.id.center_frame, viewPageFragment);
		t.commit();
	}

	private void initListener() {
		viewPageFragment.setMyPageChangeListener(new MyPageChangeListener() {
			@Override
			public void onPageSelected(int position) {
				if(viewPageFragment.isFirst()){
					mSlidingMenu.setCanSliding(true);
				}else{
					mSlidingMenu.setCanSliding(false);
				}
			}
		});
	}
    
	public static void refresh()
	{
		 Intent i = new Intent();
		 i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
		 i.setClassName(SlidingActivity.context, "com.example.slidingmenu.activity.SlidingActivity");                    
		 SlidingActivity.context.startActivity(i);
		 ViewPageFragment.pagerItemList.clear();	
	}
	
	public static void refresh1()
	{    
		ViewPageFragment.pagerItemList = new ArrayList<Fragment>();
		PageFragment2 page2 = new PageFragment2();
		ViewPageFragment.pagerItemList.add(page2);
//		 Intent i = new Intent();
//		 i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//		 i.setClassName(SlidingActivity.context, "com.example.slidingmenu.activity.MapActivity");                    
//		 SlidingActivity.context.startActivity(i);
	}
	
	public void showLeft() {
		mSlidingMenu.showLeftView();
	}

}

这个是我Activity的代码

package com.example.slidingmenu.fragment;

import java.util.ArrayList;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.ViewGroup;
import android.widget.Button;

import com.example.slidingmenu.R;
import com.example.slidingmenu.activity.SlidingActivity;

public class ViewPageFragment extends Fragment {

	private Button showLeft;
	private MyAdapter mAdapter;
	private ViewPager mPager;
	public static ArrayList<Fragment> pagerItemList;

	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View mView = inflater.inflate(R.layout.view_pager, null);
		showLeft = (Button) mView.findViewById(R.id.showLeft);
		mPager = (ViewPager) mView.findViewById(R.id.pager);
		PageFragment1 page1 = new PageFragment1();
		PageFragment2 page2 = new PageFragment2();
		PageFragment3 page3 = new PageFragment3();
		pagerItemList = new ArrayList<Fragment>();
		pagerItemList.add(page3);
		if(SlidingActivity.a==0)
		{
		pagerItemList.add(page1);
		}
		else if(SlidingActivity.a==2)
		{
		pagerItemList.add(page2);
		}
		
//		
		mAdapter = new MyAdapter(getFragmentManager());
		mPager.setAdapter(mAdapter);
		mPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {

			@Override
			public void onPageSelected(int position) {

				if (myPageChangeListener != null)
					myPageChangeListener.onPageSelected(position);
			}

			@Override
			public void onPageScrolled(int arg0, float arg1, int arg2) {
				
			}

			@Override
			public void onPageScrollStateChanged(int position) {
				
			}
		});

		return mView;
	}

	public void onActivityCreated(Bundle savedInstanceState) {

		super.onActivityCreated(savedInstanceState);

		showLeft.setOnClickListener(new OnClickListener() {

			@Override
			public void onClick(View v) {
				((SlidingActivity) getActivity()).showLeft();
			}
		});
	}

	public boolean isFirst() {
		if (mPager.getCurrentItem() == 0)
			return true;
		else
			return false;
	}

	public boolean isEnd() {
		if (mPager.getCurrentItem() == pagerItemList.size() - 1)
			return true;
		else
			return false;
	}

	public class MyAdapter extends FragmentPagerAdapter {
		public MyAdapter(FragmentManager fm) {
			super(fm);
		}

		@Override
		public int getCount() {
			return pagerItemList.size();
		}

		@Override
		public Fragment getItem(int position) {

			Fragment fragment = null;
			if (position < pagerItemList.size())
				fragment = pagerItemList.get(position);
			else
				fragment = pagerItemList.get(0);

			return fragment;

		}
	}

	private MyPageChangeListener myPageChangeListener;

	public void setMyPageChangeListener(MyPageChangeListener l) {

		myPageChangeListener = l;

	}

	public interface MyPageChangeListener {
		public void onPageSelected(int position);
	}

}

这个是侧边栏的代码

package com.example.slidingmenu.fragment;

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;

import com.example.slidingmenu.R;
import com.example.slidingmenu.activity.SlidingActivity;

public class LeftFragment extends Fragment {
	ListView listView;
	public View onCreateView(LayoutInflater inflater, ViewGroup container,
			Bundle savedInstanceState) {
		View view = inflater.inflate(R.layout.left, null);
		if (container == null) {
	          return null;
	       }
	                listView = (ListView) view.findViewById(R.id.newlistview);
	                String[] item = new String[] {"HomePage", "News", "Web", "Map"};
	                ArrayAdapter<String> files = new ArrayAdapter<String>(getActivity(), 
	                        android.R.layout.simple_list_item_1,item);                       
	                listView.setAdapter(files);
	                listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {

			         @Override
			         public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
			        	 if(position==2)
			        	 {
			        		 SlidingActivity.a=0;
			        		 ViewPageFragment.pagerItemList=new ArrayList<Fragment>();
			        		 SlidingActivity.refresh1(); 
			        	 }
			        	 if(position==1)
			        	 {
			        		 SlidingActivity.a=0;
			        		 ViewPageFragment.pagerItemList=new ArrayList<Fragment>();
			        		 SlidingActivity.refresh();
			        	 }
			         }
				       });
	        return view;
	}

	public void onActivityCreated(Bundle savedInstanceState) {
		super.onActivityCreated(savedInstanceState);
	}

}

这个是左边目录的代码，然后单个的fragment对应一个XML。

请各位大大指教。。。

貌似那个程序里面少一个ABS的包？ 不好意思我是初学者 那个是系统自带需要导入的包么？》

[kyle_nirvana]

有人能帮忙一下么
