引入ViewPagerIndicator库 2. 编写布局文件com.viewpagerindicator.TabPageIndicatorandroid:idid/indicatorandroid:layout_widthfill_parentandroid:layout_heightwrap_content /3. mIndicator.setViewPager(mViewPager);//将viewpager和mIndicator关联起来,必须在viewpager设置完adapter后才能调用4. 重写PagerAdapter方法,返回页面标题/*** 重写此方法,返回页面标题,用于viewpagerIndicator的页签显示*/Overridepublic CharSequence getPageTitle(int position) {return mNewsTabData.get(position).title;}5. 自定义样式修改 清单文件activityandroid:name.MainActivityandroid:themestyle/Theme.PageIndicatorDefaults /
