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

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

附上链接工程：

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
