本人参考了http://www.cnblogs.com/chaoxiyouda/p/5265936.html的文章，并在其基础上稍作更改，增加了部分注释

效果图

                    
关键代码：mainActivity中slidingTabLayout.setTabTitleTextSize(14);//标题字体大小slidingTabLayout.setTitleTextColor(Color.BLACK, Color.RED);//标题字体颜色slidingTabLayout.setTabStripWidth(40);//滑动条宽度slidingTabLayout.setSelectedIndicatorColors(Color.RED,Color.BLACK,Color.YELLOW);//滑动条颜色slidingTabLayout.setDistributeEvenly(false); //均匀平铺选项卡slidingTabLayout.setViewPager(viewPager);//最后调用此方法SlidingTabStrip自定义控件中：源代码canvas.drawRect(left + cutWidth, height - mSelectedIndicatorThickness, right - cutWidth,        height, mSelectedIndicatorPaint);更改后代码，想设计什么长度自己去拓展mSelectionOffset是滚动比例if(mSelectionOffset<=0.5){    Log.w("输出0.5以下",right - cutWidth+mSelectionOffset*tabWidth+"");    canvas.drawRect(left + cutWidth, height - mSelectedIndicatorThickness, right - cutWidth+mSelectionOffset*tabWidth,            height, mSelectedIndicatorPaint);}else {    Log.w("输出0.5以上",right - cutWidth+(mSelectionOffset-0.50)*tabWidth+"");    canvas.drawRect(left + cutWidth, height - mSelectedIndicatorThickness, (float) (right - cutWidth+(1-mSelectionOffset)*tabWidth),            height, mSelectedIndicatorPaint);}
注意：在Android5.0之后如果需要去掉分隔线，去掉悬浮状态，套上AppBarLayout并设置app:elevation="0dp"
<android.support.design.widget.AppBarLayout    android:layout_width="match_parent"    android:layout_height="wrap_content"    app:elevation="0dp">    <org.xufei.sliding_tab.SlidingTabLayout    android:id="@+id/sliding_tabs"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:translationZ="3dp"    android:background="#ffffff"/>
</android.support.design.widget.AppBarLayout>
