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:///"; // 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); ButtonView b = new ButtonView(R.string.pay_name_alipay); buttonListView.add(b); listAdapter = new ListAdapter(buttonListView); leftListView.setAdapter(listAdapter); leftListView.setDividerHeight(0); // listview点击事件 leftListView.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Log.e("tag", Integer.toString(position)); // TODO Auto-generated method stub listAdapter.setSelectedPosition(position); listAdapter.notifyDataSetInvalidated(); if (position % 2 == 1) { fragmentViewPager.setCurrentItem(1); }else{ fragmentViewPager.setCurrentItem(0); } } }); } public void initDatasViewPager() { fragmentlist = new ArrayList<Fragment>(); fragment1 = new Fragment1();// fragment2 = new Fragment2();// fragmentlist.add(fragment1); fragmentlist.add(fragment2);

Fragment1.java

public class Fragment1 extends Fragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub return inflater.inflate(R.layout.fragment1, container, false); } }

Fragment2.java

public class Fragment2 extends Fragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub return inflater.inflate(R.layout.fragment2, container, false); } }
