Android使用fragment实现左侧导航

使用简单的fragment实现左侧导航，供大家参考，具体内容如下

先上效果图：

MainActivity.java

public class MainActivity extends FragmentActivity {
// private Handler handler;
private ViewPager fragmentViewPager;
private ListView leftListView;
private List<Fragment> fragmentlist;
private Fragment1 fragment1;
private Fragment2 fragment2;
private ArrayList<String> leftlist = new ArrayList<String>();// left list

private ListAdapter listAdapter = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
 // TODO Auto-generated method stub
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 fragmentViewPager = (ViewPager) findViewById(R.id.fragmentViewPager);
 leftListView = (ListView) findViewById(R.id.leftListView);

initDatas();// left初始化。
 initDatasViewPager();
 // aTextViewCallBack back = (aTextViewCallBack)
 // findViewById(R.id.aTextViewCallBack);
 // back.setCalBack(new calBack() {
 // @Override
 // public void onclick() {
 // // TODO Auto-generated method stub
 // Toast.makeText(MainActivity.this, "这是回调的点击事件哦~",
 // Toast.LENGTH_LONG).show();
 // }
 // });
 //
 // new Thread(new Runnable() {
 //
 // @Override
 // public void run() {
 // // TODO Auto-generated method stub
 // String str = "http://www.easyicon.net/";
 // String st = getHtmlByURL.getHtmlByURL(str);
 // Message msg = handler.obtainMessage(0,st);
 // handler.sendMessage(msg);
 // }
 // }).start();
 // handler = new Handler() {
 // public void handleMessage(Message msg) {
 // super.handleMessage(msg);
 // String x = msg.obj.toString();
 // Log.i("GEtHtml", x);
 // };
 // };
}

public void initDatas() {
 for (int i = 0; i < 5; i++) {
  leftlist.add("第" + i + "个");
  Log.i("65", leftlist.get(i).toString());
 }

ArrayList<ButtonView> buttonListView = new ArrayList<ButtonView>();
 ButtonView a = new ButtonView(R.string.pay_name_weixin);
 buttonListView.add(a);

 buttonListView.add(b);

listAdapter = new ListAdapter(buttonListView);
 leftListView.setAdapter(listAdapter);
 leftListView.setDividerHeight(0);
 // listview点击事件
 leftListView.setOnItemClickListener(new OnItemClickListener() {
  @Override

    int position, long id) {

   listAdapter.notifyDataSetInvalidated();

 fragmentViewPager.setAdapter(new FragmentAdapter(
   getSupportFragmentManager(), fragmentlist, this));
 fragmentViewPager.setOnPageChangeListener(new MyOnPageChangeListener());
