仿网易新闻效果源码分析

一直想知道这种效果到底是如何做出来的，直到看到代码，原来还是动画。从网上找了两份代码，原理基本相同，两份代码中应该有相互参考部分，现在简单解析下，做一个记录，另外，代码中做了些许不妨碍功能的修改（如果有时间的话，自己也会考虑用fragment实现下）。先看下效果图：

这里主要讲解的是以下部分：

仿网易新闻效果源码分析_第2张图片

先看下注释里面的说明：

/** * Android实现局部图片滑动指引效果 * @Description: 实现以下功能： * 1、顶部单张图片左右拖拉滑动； * 2、带指引； * 3、仅滑动顶部单张图片，不滑动页面，下面的图文内容不动；  * 4、类似于新闻客户端的功能

看下它的主Activity里面的全局变量（也就是上面图形）：

public class MainActivity extends ActivityGroup implements OnClickListener{// 选中的新闻条目private TextView mSelectedItem = null;// 头部新闻条目的Layoutprivate RelativeLayout mHeader = null;// 中间新闻主体的Layoutprivate RelativeLayout mNewsMainLayout = null;private LayoutParams params = null;//顶部提示private TextView mNetEaseTop = null;// 新闻分类private TextView mNewsItem = null;private TextView mInfoItem = null;private TextView mBlogItem = null;private TextView mMagezineItem = null;private TextView mDomainItem = null;private TextView mMoreItem = null;// 新闻分类中每条分类的宽度private int mItemWidth = 0;// 条目背景移动开始位置private int startX = 0;private Intent mIntent = null;// 设置新闻主题private View mNewsMain = null;

注释比较详细。可以看到这个activity继承自activityGroup类，而activityGroup类在3.0以后是deprecated，所以在开头说想要用fragment重新实现一下。

Deprecated. Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.

再看onCreate方法：

@Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);              // 初始化控件        initeViews();    }        /**     * 初始化控件     */    private void initeViews(){    mNewsItem = (TextView) findViewById(R.id.tv_title_news);    mInfoItem = (TextView) findViewById(R.id.tv_title_info);    mBlogItem = (TextView) findViewById(R.id.tv_title_blog);    mMagezineItem = (TextView) findViewById(R.id.tv_title_magazine);    mDomainItem = (TextView) findViewById(R.id.tv_title_domain);    mMoreItem = (TextView) findViewById(R.id.tv_title_more);        mNewsItem.setOnClickListener(this);    mInfoItem.setOnClickListener(this);    mBlogItem.setOnClickListener(this);    mMagezineItem.setOnClickListener(this);    mDomainItem.setOnClickListener(this);    mMoreItem.setOnClickListener(this);    // 设置选中条目属性    mSelectedItem = new TextView(this);    mSelectedItem.setText(R.string.title_news_category_tops);    mSelectedItem.setTextColor(Color.WHITE);    mSelectedItem.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 17);    mSelectedItem.setGravity(Gravity.CENTER);    mSelectedItem.setWidth((getScreenWidth() - DimensionUtility.dip2px(this, 20)) / 6);    mSelectedItem.setBackgroundResource(R.drawable.slidebar);    RelativeLayout.LayoutParams param = new RelativeLayout.LayoutParams(    LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);    param.addRule(RelativeLayout.CENTER_VERTICAL, RelativeLayout.TRUE);        mHeader = (RelativeLayout) findViewById(R.id.layout_title_bar);    mNetEaseTop = (TextView) findViewById(R.id.tv_netease_top);        mHeader.addView(mSelectedItem, param);        // 设置头条新闻主体    mIntent = new Intent(MainActivity.this, TopicNews.class);    mNewsMain = getLocalActivityManager().startActivity(    "TopicNews", mIntent).getDecorView();    params = new LayoutParams(    LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);    mNewsMainLayout = (RelativeLayout) findViewById(R.id.layout_news_main);    mNewsMainLayout.addView(mNewsMain, params);    }

这里所说的选中条目，就是上图中，选中的高亮部分，它其实可以理解为和下面六个是上下两层的关系。而mNetEaseTop是指的

这一块内容，在原代码中，作者并未做这一块和下面内容的同时更新，个人后来加上。设置头条新闻主题下面就是设置默认选择项：第一项（头条新闻）。

再来看一下里面用到的布局文件：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    android:orientation="vertical"    android:weightSum="10" >    <include        android:id="@+id/header"        layout="@layout/header" />    <RelativeLayout        android:id="@+id/layout_news_main"        android:layout_width="fill_parent"        android:layout_height="0dp"        android:layout_weight="9" >    </RelativeLayout>    <RelativeLayout        android:id="@+id/layout_bottom"        android:layout_weight="1"        android:layout_width="fill_parent"        android:layout_height="wrap_content" >        <RadioGroup            android:id="@+id/radiogroup"            android:layout_width="fill_parent"            android:layout_height="0dp"            android:background="@drawable/bottombg"            android:gravity="center_vertical"            android:orientation="horizontal" >            <RadioButton                android:id="@+id/radio_news"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_news"                android:button="@null"                android:checked="true" />            <RadioButton                android:id="@+id/radio_topic"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_topic"                android:button="@null" />            <RadioButton                android:id="@+id/radio_pic"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_pic"                android:button="@null" />            <RadioButton                android:id="@+id/radio_follow"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_follow"                android:button="@null" />            <RadioButton                android:id="@+id/radio_vote"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_vote"                android:button="@null" />        </RadioGroup>    </RelativeLayout></LinearLayout>

中间的layout_new_main就是mNewsMainLayout，起到一个占位的作用，下面的RadioGroup就是最下面的标记栏。里面用到的布局文件主要是header.xml：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="fill_parent"    android:layout_height="wrap_content"

</LinearLayout>    </RelativeLayout></LinearLayout>

比较简单的布局，不详述。

上面代码设置选中项宽带：

mSelectedItem.setWidth((getScreenWidth() - DimensionUtility.dip2px(this, 20)) / 6);

用到了getScreenWidth方法：

/**     * 获取屏幕的宽度     * @return     */    private int getScreenWidth(){    WindowManager windowManager = getWindowManager();Display display = windowManager.getDefaultDisplay();//Point point = new Point();//display.getSize(point);//int screenWidth = point.x; int screenWidth = display.getWidth();return screenWidth;    }

display的getWidth方法在3.0中好像也没deprecated。可以使用注释掉的代码获取屏幕宽度。

下面是最重要的部分点击切换：

// 新闻分类事件监听@Overridepublic void onClick(View v) {mItemWidth = findViewById(R.id.layout).getWidth();switch (v.getId()) {case R.id.tv_title_news://动画滑动ImageAnimation.SetImageSlide(mSelectedItem, startX, 0, 0, 0);//设置滑动后动画开始位置startX = 0;//设置选中项显示文字，也就是高亮部分文字mSelectedItem.setText(R.string.title_news_category_tops);//设置左上角提示文字mNetEaseTop.setText(R.string.title_news_category_tops);// 显示头条信息mIntent.setClass(MainActivity.this, TopicNews.class);mNewsMain = getLocalActivityManager().startActivity(    "TopicNews", mIntent).getDecorView();break;case R.id.tv_title_info:ImageAnimation.SetImageSlide(mSelectedItem, startX, mItemWidth, 0, 0);startX = mItemWidth;mSelectedItem.setText(R.string.title_news_category_info);mNetEaseTop.setText(R.string.title_news_category_info);// 显示资讯信息mIntent.setClass(MainActivity.this, InfoNews.class);mNewsMain = getLocalActivityManager().startActivity(    "InfoNews", mIntent).getDecorView();break;case R.id.tv_title_blog:ImageAnimation.SetImageSlide(mSelectedItem, startX, mItemWidth * 2, 0, 0);startX = mItemWidth * 2;mSelectedItem.setText(R.string.title_news_category_blog);mNetEaseTop.setText(R.string.title_news_category_blog);// 显示博客信息mIntent.setClass(MainActivity.this, BlogNews.class);mNewsMain = getLocalActivityManager().startActivity(    "BlogNews", mIntent).getDecorView();break;case R.id.tv_title_magazine:ImageAnimation.SetImageSlide(mSelectedItem, startX, mItemWidth * 3, 0, 0);startX = mItemWidth * 3;mSelectedItem.setText(R.string.title_news_category_magazine);mNetEaseTop.setText(R.string.title_news_category_magazine);// 显示杂志信息mIntent.setClass(MainActivity.this, MagazineNews.class);mNewsMain = getLocalActivityManager().startActivity(    "MagazineNews", mIntent).getDecorView();break;case R.id.tv_title_domain:ImageAnimation.SetImageSlide(mSelectedItem, startX, mItemWidth * 4, 0, 0);startX = mItemWidth * 4;mSelectedItem.setText(R.string.title_news_category_domain);mNetEaseTop.setText(R.string.title_news_category_domain);// 显示业界信息mIntent.setClass(MainActivity.this, DomainNews.class);mNewsMain = getLocalActivityManager().startActivity(    "DomainNews", mIntent).getDecorView();break;case R.id.tv_title_more:ImageAnimation.SetImageSlide(mSelectedItem, startX, mItemWidth * 5, 0, 0);startX = mItemWidth * 5;mSelectedItem.setText(R.string.title_news_category_more);mNetEaseTop.setText(R.string.title_news_category_more);// 显示更多信息mIntent.setClass(MainActivity.this, MoreNews.class);mNewsMain = getLocalActivityManager().startActivity(    "MoreNews", mIntent).getDecorView();break;default:break;}// 更换Layout中的新闻主体mNewsMainLayout.removeAllViews();mNewsMainLayout.addView(mNewsMain, params);}

在注释中，解释的已经比较清楚了，看一下ImageAnimation：

public class ImageAnimation {/** * 设置图像移动动画效果 * @param v * @param startX * @param toX * @param startY * @param toY */public static void SetImageSlide(View v, int startX, int toX, int startY, int toY) {TranslateAnimation anim = new TranslateAnimation(startX, toX, startY, toY);anim.setDuration(100);anim.setFillAfter(true);v.startAnimation(anim);}}

就是一个简单的移动动画。这样就是简单的顶部标示就完成了，接下来要分析如下：

仿网易新闻效果源码分析_第3张图片

这个代码在TopicNews中，先看下使用到的全局变量：

public class TopicNews extends Activity{// 滑动图片的集合private ArrayList<View> mImagePageViewList = null;private ViewGroup mMainView = null;private ViewPager mViewPager = null;// 当前ViewPager索引//private int pageIndex = 0; // 包含圆点图片的Viewprivate ViewGroup mImageCircleView = null;private ImageView[] mImageCircleViews = null; // 滑动标题private TextView mSlideTitle = null;// 布局设置类private SlideImageLayout mSlideLayout = null;// 数据解析类private NewsXmlParser mParser = null;

里面的viewPager类是用于滑动控件，SlideImageLayout类是用于上面图片和下面标志点的布局。NewsXmlParser类提供数据。

看一下onCreate方法：

@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setTheme(android.R.style.Theme_Translucent_NoTitleBar);// 初始化initeViews();}/** * 初始化 */private void initeViews(){// 滑动图片区域mImagePageViewList = new ArrayList<View>();LayoutInflater inflater = getLayoutInflater();  mMainView = (ViewGroup)inflater.inflate(R.layout.page_topic_news, null);mViewPager = (ViewPager) mMainView.findViewById(R.id.image_slide_page);  // 圆点图片区域mParser = new NewsXmlParser();int length = mParser.getSlideImages().length;mImageCircleViews = new ImageView[length];mImageCircleView = (ViewGroup) mMainView.findViewById(R.id.layout_circle_images);mSlideLayout = new SlideImageLayout(TopicNews.this);mSlideLayout.setCircleImageLayout(length);for(int i = 0; i < length; i++){mImagePageViewList.add(mSlideLayout.getSlideImageLayout(mParser.getSlideImages()[i]));mImageCircleViews[i] = mSlideLayout.getCircleImageLayout(i);mImageCircleView.addView(mSlideLayout.getLinearLayout(mImageCircleViews[i], 10, 10));}// 设置默认的滑动标题mSlideTitle = (TextView) mMainView.findViewById(R.id.tvSlideTitle);mSlideTitle.setText(mParser.getSlideTitles()[0]);setContentView(mMainView);// 设置ViewPager        mViewPager.setAdapter(new SlideImageAdapter());          mViewPager.setOnPageChangeListener(new ImagePageChangeListener());}

看一下远点图片区域：

// 圆点图片区域mParser = new NewsXmlParser();int length = mParser.getSlideImages().length;mImageCircleViews = new ImageView[length];mImageCircleView = (ViewGroup) mMainView.findViewById(R.id.layout_circle_images);mSlideLayout = new SlideImageLayout(TopicNews.this);mSlideLayout.setCircleImageLayout(length);for(int i = 0; i < length; i++){mImagePageViewList.add(mSlideLayout.getSlideImageLayout(mParser.getSlideImages()[i]));mImageCircleViews[i] = mSlideLayout.getCircleImageLayout(i);mImageCircleView.addView(mSlideLayout.getLinearLayout(mImageCircleViews[i], 10, 10));}

里面主要是调用了NewsXmlParser类和SlideImageLayout的方法，那就先看下NewsXmlParser的getSlideImages方法：

public int[] getSlideImages(){return slideImages;}

这里的slideImage是在类中定义好的：

// 滑动图片的集合，这里设置成了固定加载，当然也可动态加载。private int[] slideImages = {R.drawable.image01,R.drawable.image02,R.drawable.image03,R.drawable.image04,R.drawable.image05};

那看一下用到的SlideImageLayout类的getSlideImageLayout：获取图片的布局：

/** * 生成滑动图片区域布局 * @param id * @return */public View getSlideImageLayout(int id){// 包含TextView的LinearLayoutLinearLayout imageLinerLayout = new LinearLayout(mContext);LinearLayout.LayoutParams imageLinerLayoutParames = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT,1);ImageView iv = new ImageView(mContext);iv.setBackgroundResource(id);iv.setOnClickListener(new ImageOnClickListener());imageLinerLayout.addView(iv,imageLinerLayoutParames);mImageList.add(iv);return imageLinerLayout;}

创建一个layout，然后再创建一个imageView,把ImageView加入到layout中，然后返回layout。同理，我们再看下set和getCircleImageLayout：

 * 设置圆点个数 * @param size */public void setCircleImageLayout(int size){mImageViews = new ImageView[size];}/** * 生成圆点图片区域布局对象 * @param index * @return */public ImageView getCircleImageLayout(int index){mImageView = new ImageView(mContext);  mImageView.setLayoutParams(new LayoutParams(10,10));        mImageView.setScaleType(ScaleType.FIT_XY);                mImageViews[index] = mImageView;                 if (index == 0) {              //默认选中第一张图片            mImageViews[index].setBackgroundResource(R.drawable.dot_selected);          } else {              mImageViews[index].setBackgroundResource(R.drawable.dot_none);          }                   return mImageViews[index];}

获取圆点图片的Image，然后返回。

在initViews中还有设置滑动图片标题：

// 设置默认的滑动标题mSlideTitle = (TextView) mMainView.findViewById(R.id.tvSlideTitle);mSlideTitle.setText(mParser.getSlideTitles()[0]);setContentView(mMainView);

最后是设置Viewpager的Adapter还有监听

// 设置ViewPager        mViewPager.setAdapter(new SlideImageAdapter());          mViewPager.setOnPageChangeListener(new ImagePageChangeListener());

先来看下SlideImageAdapter类：

// 滑动图片数据适配器    private class SlideImageAdapter extends PagerAdapter {          @Override          public int getCount() {             return mImagePageViewList.size();          }            @Override          public boolean isViewFromObject(View view, Object object) {              return view == object;          }            @Override          public int getItemPosition(Object object) {              return super.getItemPosition(object);          }            @Override          public void destroyItem(View view, int arg1, Object arg2) {              ((ViewPager) view).removeView(mImagePageViewList.get(arg1));          }            @Override          public Object instantiateItem(View view, int position) {          ((ViewPager) view).addView(mImagePageViewList.get(position));                        return mImagePageViewList.get(position);          }            @Override          public void restoreState(Parcelable arg0, ClassLoader arg1) {            }            @Override          public Parcelable saveState() {              return null;          }            @Override          public void startUpdate(View arg0) {          }            @Override          public void finishUpdate(View arg0) {          }      }

一个典型的适配器类，主要看下面两个方法：

@Override          public void destroyItem(View view, int arg1, Object arg2) {              ((ViewPager) view).removeView(mImagePageViewList.get(arg1));          }            @Override          public Object instantiateItem(View view, int position) {          ((ViewPager) view).addView(mImagePageViewList.get(position));                        return mImagePageViewList.get(position);          }

实例化Item和销毁Item。我们在initViews方法里面为mImagePageViewList里面加载了很多view，在这里取出，加入到ViewPager中去。

其实他的滑动监听事件特别简单，就是改变下选中图片、标识圆点和标题文字：

// 滑动页面更改事件监听器    private class ImagePageChangeListener implements OnPageChangeListener {        @Override          public void onPageScrollStateChanged(int arg0) {          }            @Override          public void onPageScrolled(int arg0, float arg1, int arg2) {          }            @Override          public void onPageSelected(int index) {  //        pageIndex = index;        mSlideLayout.setPageIndex(index);        mSlideTitle.setText(mParser.getSlideTitles()[index]);                    for (int i = 0; i < mImageCircleViews.length; i++) {              mImageCircleViews[index].setBackgroundResource(R.drawable.dot_selected);                                if (index != i) {                  mImageCircleViews[i].setBackgroundResource(R.drawable.dot_none);                  }              }        }      }

还有，在网易新闻里，有个底部标记栏：

这个功能是如何实现的呢？

<RelativeLayout        android:id="@+id/layout_bottom"        android:layout_weight="1"        android:layout_width="fill_parent"        android:layout_height="wrap_content" >        <RadioGroup            android:id="@+id/radiogroup"            android:layout_width="fill_parent"            android:layout_height="0dp"            android:background="@drawable/bottombg"            android:gravity="center_vertical"            android:orientation="horizontal" >            <RadioButton                android:id="@+id/radio_news"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_news"                android:button="@null"                android:checked="true" />            <RadioButton                android:id="@+id/radio_topic"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_topic"                android:button="@null" />            <RadioButton                android:id="@+id/radio_pic"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_pic"                android:button="@null" />            <RadioButton                android:id="@+id/radio_follow"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_follow"                android:button="@null" />            <RadioButton                android:id="@+id/radio_vote"                android:layout_width="wrap_content"                android:background="@drawable/tab_selector_vote"                android:button="@null" />        </RadioGroup>    </RelativeLayout>

其中background图片：

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:drawable="@drawable/current_topic_tab" android:state_checked="true"/>    <item android:drawable="@drawable/back_topic_tab" android:state_checked="false"/></selector>

切换代码：

@Overridepublic void onCheckedChanged(RadioGroup group, int checkedId) {switch (checkedId) {case R.id.radio_news:ImageAnimation.SetImageSlide(mImageView, startLeft, 0, 0, 0);startLeft = 0;break;case R.id.radio_topic:ImageAnimation.SetImageSlide(mImageView, startLeft, mImageView.getWidth(), 0, 0);startLeft = mImageView.getWidth();break;case R.id.radio_pic:ImageAnimation.SetImageSlide(mImageView, startLeft, mImageView.getWidth() * 2, 0, 0);startLeft = mImageView.getWidth() * 2;break;case R.id.radio_follow:ImageAnimation.SetImageSlide(mImageView, startLeft, mImageView.getWidth() * 3, 0, 0);startLeft = mImageView.getWidth() * 3;break;case R.id.radio_vote:ImageAnimation.SetImageSlide(mImageView, startLeft, mImageView.getWidth() * 4, 0, 0);startLeft = mImageView.getWidth() * 4;break;default:break;}
