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
