UI系列教程第八课：Lance老师UI系列教程第八课->新浪新闻SlidingMenu界面的实现

今天蓝老师要讲的是关于新浪新闻侧滑界面的实现。先看看原图：

如图所示，这种侧滑效果以另一种方式替代了原先tab导航的那种用户体验方式

给人耳目一新的感觉，现已被广大知名应用所效仿，如新浪新闻，网易新闻，人人网等

那么这种效果该如何实现呢？那就需要用到一个开源库SlidingMenu

Github地址：https://github.com/jfeinstein10/SlidingMenu

里面包含了demo示例，相关效果图如下：

同时该库又依赖另一个开源库ActionBarSherkLock ,有关该库的介绍，请看此博文http://blog.csdn.net/geniuseoe2012/article/details/9046487

大家最好先把官方demo跑一遍，理清里边的依赖关系以及对库的基本使用，这样自己运用到项目当中就可以得心应手了

OK，最后言归正传，看看新浪新闻的侧滑实现，先上山寨版效果图：

代码片段：

public class MainActivity extends SlidingFragmentActivity implements OnClickListener{

	private static final CommonLog log = LogFactory.createLog();

	private String mTitle;

	private Fragment mContent;

	private ImageView mLeftIcon;

	private ImageView mRightIcon;

	private TextView mTitleTextView;

	private FragmentControlCenter mControlCenter;

	@Override

	public void onCreate(Bundle savedInstanceState) {

		// TODO Auto-generated method stub

		super.onCreate(savedInstanceState);

		mControlCenter = FragmentControlCenter.getInstance(this);

		setupViews();

		initData();

	}

	private void setupViews(){

		setContentView(R.layout.main_slidemenu_layout);

		initActionBar();

		initSlideMenu();

	}

	private void initSlideMenu(){

		FragmentModel fragmentModel = mControlCenter.getTouTiaoFragmentModel();

		switchContent(fragmentModel);

		SlidingMenu sm = getSlidingMenu();

		sm.setMode(SlidingMenu.LEFT_RIGHT);

		setBehindContentView(R.layout.left_menu_frame);

		sm.setSlidingEnabled(true);

		sm.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);

		sm.setShadowWidthRes(R.dimen.shadow_width);

		sm.setShadowDrawable(R.drawable.shadow);

		getSupportActionBar().setDisplayHomeAsUpEnabled(true);

		getSupportFragmentManager()

		.beginTransaction()

		.replace(R.id.left_menu_frame, new NavigationFragment())

		.commit();

		sm.setBehindOffsetRes(R.dimen.slidingmenu_offset);

		sm.setBehindScrollScale(0);

		sm.setFadeDegree(0.25f);

		sm.setSecondaryMenu(R.layout.right_menu_frame);

		sm.setSecondaryShadowDrawable(R.drawable.shadow);

		getSupportFragmentManager()

		.beginTransaction()

		.replace(R.id.right_menu_frame, new SettingFragment())

		.commit();

	}

	private void initActionBar(){

		ActionBar actionBar = getSupportActionBar();

		actionBar.setCustomView(R.layout.actionbar_layout);

		actionBar.setDisplayShowCustomEnabled(true);

		actionBar.setDisplayShowHomeEnabled(false);

		mLeftIcon = (ImageView) findViewById(R.id.iv_left_icon);

		mRightIcon = (ImageView) findViewById(R.id.iv_right_icon);

		mLeftIcon.setOnClickListener(this);

		mRightIcon.setOnClickListener(this);

		mTitleTextView = (TextView) findViewById(R.id.tv_title);

	}

	private void initData(){

	}

	public void switchContent(final FragmentModel fragment) {

		mTitle = fragment.mTitle;

		mContent = fragment.mFragment;

		getSupportFragmentManager()

		.beginTransaction()

		.replace(R.id.content_frame, mContent)

		.commit();

		Handler h = new Handler();

		h.postDelayed(new Runnable() {

			public void run() {

				getSlidingMenu().showContent();

			}

		}, 50);

		mTitleTextView.setText(mTitle);

	}

	@Override

	public void onClick(View view) {

		switch(view.getId()){

		case R.id.iv_left_icon:

			toggle();

			break;

		case R.id.iv_right_icon:

			showSecondaryMenu();

			break;

		}

	}	

}

这里actionbar使用自定义布局，主要是使用ActionBarSherklock里的默认布局不知道怎么把title标题居中

找了半天没发现相关属性，如果有童鞋知道麻烦告知

NavigationFragment是左侧菜单

public class NavigationFragment extends Fragment implements OnCheckedChangeListener, OnClickListener{

	private static final CommonLog log = LogFactory.createLog();

	private View mView;

	private RadioGroup  m_radioGroup;

	private ImageButton m_AddButton;

	private FragmentControlCenter mControlCenter;

	public NavigationFragment(){

	}

	@Override

	public void onCreate(Bundle savedInstanceState) {

		// TODO Auto-generated method stub

		super.onCreate(savedInstanceState);

		log.e("NavigationFragment onCreate");

		mControlCenter = FragmentControlCenter.getInstance(getActivity());

	}

	@Override

	public void onDestroy() {

		// TODO Auto-generated method stub

		super.onDestroy();

		log.e("NavigationFragment onDestroy");

	}

	@Override

	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

		log.e("NavigationFragment onCreateView");

		mView = inflater.inflate(R.layout.navitation_channel_layout, null);

		return mView;

	}

	@Override

	public void onActivityCreated(Bundle savedInstanceState) {

		super.onActivityCreated(savedInstanceState);

		log.e("NavigationFragment onActivityCreated");

		setupViews();

	}

	private void setupViews(){

		m_radioGroup = (RadioGroup) mView.findViewById(R.id.nav_radiogroup);

		((RadioButton) m_radioGroup.getChildAt(0)).toggle();

		m_radioGroup.setOnCheckedChangeListener(this);

		m_AddButton = (ImageButton) mView.findViewById(R.id.ib_add_content);

		m_AddButton.setOnClickListener(this);

	}

	@Override

	public void onCheckedChanged(RadioGroup arg0, int id) {

		switch(id){

		case R.id.rb_toutiao:

			goTouTiaoFragment();

			break;

		case R.id.rb_yule:

			goYuLeFragment();

			break;

		case R.id.rb_tech:

			goTechFragment();

			break;

		case R.id.rb_blog:

			goBlogFragment();

			break;

		}

	}

	private void goTouTiaoFragment(){

		if (getActivity() == null)

			return;

		FragmentModel fragmentModel = mControlCenter.getTouTiaoFragmentModel();

		if (getActivity() instanceof MainActivity) {

			MainActivity ra = (MainActivity) getActivity();

			ra.switchContent(fragmentModel);

		}

	}

	private void goYuLeFragment(){

		if (getActivity() == null)

			return;

		FragmentModel fragmentModel = mControlCenter.getYuLeFragmentModel();

		if (getActivity() instanceof MainActivity) {

			MainActivity ra = (MainActivity) getActivity();

			ra.switchContent(fragmentModel);

		}

	}

	private void goTechFragment(){

		if (getActivity() == null)

			return;

		FragmentModel fragmentModel = mControlCenter.getTechFragmentModel();

		if (getActivity() instanceof MainActivity) {

			MainActivity ra = (MainActivity) getActivity();

			ra.switchContent(fragmentModel);

		}

	}

	private void goBlogFragment(){

		if (getActivity() == null)

			return;

		FragmentModel fragmentModel = mControlCenter.getBlogFragmentModel();

		if (getActivity() instanceof MainActivity) {

			MainActivity ra = (MainActivity) getActivity();

			ra.switchContent(fragmentModel);

		}

	}

	@Override

	public void onClick(View v) {

		switch(v.getId()){

		case R.id.ib_add_content:

			Toast.makeText(getActivity(), "添加尼妹,现在没内容！！！", Toast.LENGTH_SHORT).show();

			break;

		}

	}

}

SettingFragment是右侧菜单

public class SettingFragment extends Fragment{

	private static final CommonLog log = LogFactory.createLog();

	private View mView;

	public SettingFragment(){

	}

	@Override

	public void onCreate(Bundle savedInstanceState) {

		// TODO Auto-generated method stub

		super.onCreate(savedInstanceState);

		log.e("SettingFragment onCreate");

	}

	@Override

	public View onCreateView(LayoutInflater inflater, ViewGroup container,

			Bundle savedInstanceState) {

		log.e("SettingFragment onCreateView");

		View view = inflater.inflate(R.layout.setting_layout, null);

		return view;

	}

	@Override

	public void onActivityCreated(Bundle savedInstanceState) {

		super.onActivityCreated(savedInstanceState);

		log.e("SettingFragment onActivityCreated");

		setupViews();

	}

	private void setupViews(){

	}

	@Override

	public void onDestroy() {

		// TODO Auto-generated method stub

		super.onDestroy();

		log.e("SettingFragment onDestroy");

	}

}

两个fragment是附在主activity上的，其它的大伙自个儿down代码看吧

压缩包解开后有如下目录：

前面三个都是链接库，彼此又有依赖，最后工程再依赖前面三者，添加完毕后就可以正常running了
