##ViewPager滑动时分页的小圆点,使用这个控件可以免去控制小圆点变化的繁琐;
##代码参考 ####在xml布局中引入'PagerPointView',然后设置一些属性:
<com.jerry.pagepoint.PagePointView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_marginBottom="50dp"
android:layout_centerHorizontal="true"
app:ppv_pointRadius="5dp"
app:ppv_hasBorder="true"
app:ppv_borderWidth="1dp"
app:ppv_focusPointColor="@android:color/black"
app:ppv_unfocusPointColor="@android:color/white"
android:id="@+id/point"
/>
####在代码中给PagePointView设置ViewPager就行了
ViewPager viewPager = (ViewPager) findViewById(R.id.viewPager);
PagePointView point = (PagePointView) findViewById(R.id.point);
viewPager.setAdapter(adapter);
point.setViewPager(viewPager);
###注意:在给PagePointView设置ViewPager之前先给ViewPager设置Adapter
