Fragment实现android的设置界面切换效果

先上效果：

主界面代码：

/**
 * 演示用Fragment实现平板的<设置>界面

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;

	@Override
	protected 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(){
			@Override
			public 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;
			}

			@Override
			public long getItemId(int position) {
				return position;
			}

			@Override
			public Object getItem(int position) {
				return null;
			}

			@Override
			public int getCount() {
				return titles.length;
			}
		});
		lv_main_title.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public 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;
	}
	
}
