主界面代码：
/** * 演示用Fragment实现平板的<设置>界面 * @author Melon 2013-11-19 * */public class MainActivity extends Activity {private ListView lv_main_title;private static String[] titles = { "Fragment1", "Fragment2", "Fragment3" };private FragmentManager fragmentManager;private int currentItem;//private View preClickedItem;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);initView();fragmentManager = getFragmentManager();showCurrentContent(1);//显示默认条目内容}private void initView() {lv_main_title = (ListView) findViewById(R.id.lv_main_title);lv_main_title.setAdapter(new BaseAdapter(){@Overridepublic View getView(int position, View convertView, ViewGroup parent) {Log.i("WYL", "getView");TextView tv = new TextView(getApplicationContext());tv.setText(titles[position]);tv.setGravity(Gravity.CENTER);tv.setTextColor(Color.BLACK);tv.setTextSize(40);if(position == currentItem){tv.setBackgroundColor(Color.BLUE);}return tv;}@Overridepublic long getItemId(int position) {return position;}@Overridepublic Object getItem(int position) {return null;}@Overridepublic int getCount() {return titles.length;}});lv_main_title.setOnItemClickListener(new OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {showCurrentContent(position);//如果不用adapter更新数据，可以用以下代码，切换条目颜色 (就效率来说，下面的更好，adapter更新会调用全部条目的getView()，而下面的方式只会调用一个)//if(preClickedItem != null)//preClickedItem.setBackgroundColor(Color.parseColor("#FFC125"));//view.setBackgroundColor(Color.BLUE);//preClickedItem = view;}});}/** * 显示条目内容 * @param item 指定条目，对应listview条目 ，从0开始 */private void showCurrentContent(int item) {if(item >= titles.length){Toast.makeText(getApplicationContext(), "内容不存在...", 0).show();return;}//点击时判断，如果是当前条目，则提示用户if(currentItem == item){Toast.makeText(getApplicationContext(), "重复点击", 0).show();return;}Fragment fragment = null;switch (item) {case 0:fragment = new Fragment1();break;case 1:fragment = new Fragment2();break;case 2:fragment = new Fragment3();break;}FragmentTransaction beginTransaction = fragmentManager.beginTransaction();beginTransaction.replace(R.id.ll_main_content, fragment);beginTransaction.commit();//通知数据更新((BaseAdapter)lv_main_title.getAdapter()).notifyDataSetChanged();currentItem = item;}}
