使用简单的fragment实现左侧导航

使用简单的fragment实现。

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 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);
		// };
		// };
	}
