android 中 viewpager 滑动的指示器

1.   先看下效果图：

这个需要用到1个开源的 库，这个后面也会说下的。

工程目录：

这个是每个标签卡中间  没想间隔线的那个效果，想要间隔线效果的话  在这个开源包的demo里面 tabs 里面有。但是下面的指示器 就不是随动的了。是按照选中标签卡后才会直接变化的，就不放效果图了。

1. MainActivity.java

public class MainActivity extends FragmentActivity {private ViewPagerFrameAdapter adapter;        //适配器（标题和内容）private ViewPager mPager;                           private TabPageIndicator         tabbPageIndicator;         //private UnderlinePageIndicatorEx underlinePageIndicator;private  int COUNT = 0;private List<String>   titles = new ArrayList<String>(); //标题@Overrideprotected void onCreate(Bundle bundle) {     super.onCreate(bundle); requestWindowFeature(Window.FEATURE_NO_TITLE);  setContentView(R.layout.activity_main);  //标题，这里自己造的假数据 for (int j = 0; j < 3 ; j++){               titles.add( "第"+ j +"标签卡");  }          mPager = (ViewPager)findViewById(R.id.pager);             adapter = new ViewPagerFrameAdapter(getSupportFragmentManager(),titles);     mPager.setAdapter(adapter);      //得到指示器 tabbPageIndicator = (TabPageIndicator) findViewById(R.id.tab_indicator);    tabbPageIndicator.setViewPager(mPager);     //下标 underlinePageIndicator = (UnderlinePageIndicatorEx)findViewById(R.id.underline_indicator); underlinePageIndicator.setViewPager(mPager); underlinePageIndicator.setFades(false);     //设置指示器     tabbPageIndicator.setOnPageChangeListener(underlinePageIndicator);}    //adapter 没啥好说的 跟前面的一样private class ViewPagerFrameAdapter extends FragmentStatePagerAdapter{private List<String> title; //页面标题头部数据public ViewPagerFrameAdapter(FragmentManager fm, List<String> title) {super(fm);this.title = title;}//根据position 返回 fragment@Overridepublic Fragment getItem(int position) {return ArrayFragment.newInstance(position);}        //size@Overridepublic int getCount() {     return title.size();}//顶部的title@Overridepublic CharSequence getPageTitle(int position) {if (titles != null){return titles.get(position).toString();}return super.getPageTitle(position);}}}

UnderlinePageIndicatorEx.java

//继承这个然后重写public class UnderlinePageIndicatorEx extends UnderlinePageIndicator{    public UnderlinePageIndicatorEx(Context context) {   super(context, null);       }    public UnderlinePageIndicatorEx(Context context, AttributeSet attrs) {    super(context, attrs, R.attr.vpiUnderlinePageIndicatorStyle);    }    public UnderlinePageIndicatorEx(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);            }       //自身的 ViewPage传递过去    @Override    public void setViewPager(ViewPager viewPager) {    if (mViewPager == viewPager){            return;        }     //        if (mViewPager != null) {//            mViewPager.setOnPageChangeListener(null);//        }                if (viewPager.getAdapter() == null) {            throw new IllegalStateException(" pager 没有 加入 adapter");        }                mViewPager = viewPager;//        mViewPager.setOnPageChangeListener(this);        invalidate();                post(new Runnable(){            @Override public void run() {                if (mFades) {                    post(mFadeRunnable);                }            }              });     }    }

ArrayFragment.java

public class ArrayFragment extends Fragment{private int position;public ArrayFragment(int position){this.position = position;} // 返回   viwePager 下面滑动的页面public static ArrayFragment newInstance(int position){return new ArrayFragment(position);}@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);}@Overridepublic void onDestroy() {super.onDestroy();}// 根据position 返回不同的view@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {View view = inflater.inflate(R.layout.layoutaa, null);return view;}}

好了接下来是 布局xml了。

<LinearLayout        xmlns:android="http://schemas.android.com/apk/res/android"        android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:orientation="vertical"      >   <!--  标题      和      标题下面的  指示器  -->     <LinearLayout        android:layout_width="fill_parent"        android:layout_height="35dp"        android:orientation="vertical"        android:background="@drawable/main_header_background">                <com.viewpagerindicator.TabPageIndicator        android:id="@+id/tab_indicator"        android:layout_height="wrap_content"        android:layout_width="fill_parent"/>            <com.test.linepagerindictor.widget.UnderlinePageIndicatorEx        android:id="@+id/underline_indicator"        android:layout_height="3dip"        android:layout_width="fill_parent"        android:layout_alignParentBottom="true"/>               </LinearLayout>            <android.support.v4.view.ViewPager        android:id="@+id/pager"        android:layout_width="fill_parent"        android:layout_height="fill_parent"/>    </LinearLayout>

接下来设置 滑动指示器的style

  <!-- 总 style  直接引用  这个   由  tab style  和    Indicator style 组成 -->    <style name="StyledAllIndicators" parent="@android:style/Theme.Light">        <item name="vpiTabPageIndicatorStyle">@style/CustomTabPageIndicator</item>        <item name="vpiUnderlinePageIndicatorStyle">@style/CustomUnderlinePageIndicator</item>    </style>        <!-- tab的 style -->    <style name="CustomTabPageIndicator" parent="Widget.TabPageIndicator">        <item name="android:background">#00000000</item>        <item name="android:textAppearance">@style/CustomTabPageIndicator_text</item>        <item name="android:textColor">@color/selector_tab</item>        <item name="android:textSize">20sp</item>                <!-- 分割线，可有可无的 -->        <item name="android:divider">@drawable/custom_tab_indicator_divider</item>        <item name="android:dividerPadding">10dip</item>        <item name="android:showDividers">middle</item>              <item name="android:paddingTop">4dp</item>        <item name="android:paddingLeft">8dp</item>        <item name="android:paddingBottom">4dp</item>        <item name="android:paddingRight">8dp</item>                <item name="android:fadingEdge">horizontal</item>        <item name="android:fadingEdgeLength">8dp</item>    </style>        <style name="CustomTabPageIndicator_text" parent="android:TextAppearance.Medium">        <item name="android:typeface">monospace</item>    </style>            <!--  下标的指示器的颜色 -->    <style name="CustomUnderlinePageIndicator">        <item name="selectedColor">#EB5548</item>        <item name="android:background">#00000000</item>        <item name="fadeLength">1000</item>        <item name="fadeDelay">1000</item>    </style>

selector_tab.xml     这个是 选择器 在style中引用的，是用来切换 被选中的背景色的

<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android">    <item android:state_selected="true" android:color="#91D228" />    <item android:state_focused="true" android:color="#91D228" />    <item android:color="#dddddd" /></selector> 

好了 ，基本就这些了   fragment的的那个xml  自己随意画吧， 那个开源库随后上传。

2.

这个下面的指示器是根据滑动时手势滑动的，并且相应的标签卡件也有相应的分割线

这个是用到了开源的 PagerSlidingTab 的样式。 其实就是自定义了 horizontalScrollView ，但是因为鉴于一些效果稍微的不同，就需要改些相应的东西。比如控制指示器的长度不填充。

/** *滑动指示器pstsindicatorcolor颜色 *在视图的底部的全宽度的线pstsunderlinecolor颜色 *选项卡之间的分隔pstsdividercolor颜色 *滑动指示器pstsindicatorheightheight *在视图的底部的全宽度的线pstsunderlineheight高度 *pstsdividerpadding顶部和底部填充的分频器 *pststabpaddingleftright左、右填充每个选项卡 *pstsscrolloffset卷轴被选择的标签的偏移 *pststabbackground背景绘制的每个标签，应该是一个statelistdrawable *pstsshouldexpand如果设置为TRUE，每个标签都给予同样的重量，默认为false *pststextallcaps如果为真，所有选项卡标题都是大写，默认为true *  indicatorleftrightpadsize   */public class PagerSlidingTabStrip extends HorizontalScrollView {public interface IconTabProvider {public int getPageIconResId(int position);}// @formatter:offprivate static final int[] ATTRS = new int[] {android.R.attr.textSize,android.R.attr.textColor    };// @formatter:onprivate LinearLayout.LayoutParams defaultTabLayoutParams;private LinearLayout.LayoutParams expandedTabLayoutParams;private final PageListener pageListener = new PageListener();public OnPageChangeListener delegatePageListener;private LinearLayout tabsContainer;private ViewPager pager;private int tabCount;private int currentPosition = 0;private int selectedPosition = 0;private float currentPositionOffset = 0f;private Paint rectPaint;private Paint dividerPaint;private int indicatorColor = 0xFF666666;
