ViewPagerIndicator(demo)
下载地址：
demo源码
效果图：
ViewPagerIndicator在项目中很常用。我直接在项目中把需要关联的包拷贝过来了，也可以直接关联Indicator的库。
布局：
<span style="font-size:18px;"><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context=".MainActivity" ><com.example.xiangmuer.view.pagerindicator.TabPageIndicatorandroid:id="@+id/indicator"style="@style/Theme.PageIndicatorDefaults"android:layout_width="match_parent"android:layout_height="0dp"android:layout_weight="1"/><android.support.v4.view.ViewPagerandroid:id="@+id/viewpager"android:layout_width="fill_parent"android:background="#ffffff"android:layout_height="0dp"android:layout_weight="5" /></LinearLayout></span>
