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

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
