SmartTabLayout+PtrFrameLayout+ViewPager+Fragment简单实现
先来个效果：
1.引入相关layout
//下拉刷新
compile ‘in.srain.cube:ultra-ptr:1.0.11’
//Tab切换
compile ‘com.ogaclejapan.smarttablayout:library:1.6.0@aar’
compile ‘com.ogaclejapan.smarttablayout:utils-v4:1.6.0@aar’

2.属性分析
SmartTabLayout：
| 属性 | 描述 |
|---|---|
| stl_indicatorAlwaysInCenter | 如果设置为true，选中的标签总是显示在中心（如报刊亭的谷歌应用程序），默认为false |
| stl_indicatorWithoutPadding | 如果设置为真，画出没有填充标签的指标，默认为假 |
| stl_indicatorInFront | 在前面的下划线，默认的假画 |
| stl_indicatorInterpolation | 指标的行为：: ‘linear’ or ‘smart’ |
| stl_indicatorGravity | 指示器的位置: ‘bottom’ or ‘top’ or ‘center’, default ‘bottom’ |
| stl_indicatorColor | 指示剂颜色 |
| stl_indicatorColors | 该指标的多个颜色，可以设置每个标签的颜色 |
| stl_indicatorThickness | 指标的厚度 |
| stl_indicatorWidth | 指标的宽度(width), default ‘auto’ |
| stl_indicatorCornerRadius | 圆角半径的指示器 |
| stl_overlineColor | 顶线的颜色 |
| stl_overlineThickness | 顶线厚度 |
| stl_underlineColor | 底线的颜色 |
| stl_underlineThickness | 底线的厚度 |
| stl_dividerColor | 标签的颜色之间的分隔 |
| stl_dividerColors | 制表符分隔的多个颜色，可以设置每个标签的颜色 |
| stl_dividerThickness | 间隔(divider)的厚度 |
| stl_defaultTabBackground | 背景中每个选项卡。一般来说，设置statelistdrawable |
| stl_defaultTabTextAllCaps | 如果设置为真，所有标签的标题将是大写的，default true |
| stl_defaultTabTextColor | 默认的选项卡的文本颜色 |
| stl_defaultTabTextSize | 默认的选项卡的文本大小 |
| stl_defaultTabTextHorizontalPadding | 默认情况下包含的选项卡的文本布局填充 |
| stl_defaultTabTextMinWidth | tab最小宽度 |
| stl_customTabTextLayoutId | 布局标识自定义选项卡。如果不指定布局，使用默认选项卡 |
| stl_customTabTextViewId | 自定义选项卡布局中的文本视图标识。如果你不确定customtabtextlayoutid，不工作 |
| stl_distributeEvenly | 如果设置为真，每个标签都有相同的权重, default false |
| stl_clickable | 如果设置为假，请禁用选项卡的选择, default true |
| stl_titleOffset | 如果设置为“auto_center，滑块位置的标签中会不断向中心。如果指定一个维度将它从左边偏移，默认24dp |
| stl_drawDecorationAfterTab | Draw the decoration(indicator and lines) after drawing of tab, default false 绘制标签后的装饰（指标和线） |
PtrFrameLayout:
有6个参数可配置:
阻尼系数
cube_ptr:ptr_resistance=”1.7”
默认: 1.7f，越大，感觉下拉时越吃力。触发刷新时移动的位置比例
cube_ptr:ptr_ratio_of_header_height_to_refresh=”1.2”
默认，1.2f，移动达到头部高度1.2倍时可触发刷新操作。回弹延时
cube_ptr:ptr_duration_to_close=”300”
默认 200ms，回弹到刷新高度所用时间头部回弹时间
cube_ptr:ptr_duration_to_close_header=”2000”
默认1000ms刷新是否保持头部
cube_ptr:ptr_keep_header_when_refresh=”true”
默认值 true.下拉刷新 / 释放刷新
cube_ptr:ptr_pull_to_fresh=”false”
默认为false释放刷新
也可以在java代码中配置
// the following are default settings
mPtrFrame.setResistance(1.7f);
mPtrFrame.setRatioOfHeaderHeightToRefresh(1.2f);
mPtrFrame.setDurationToClose(200);
mPtrFrame.setDurationToCloseHeader(1000);
// default is false
mPtrFrame.setPullToRefresh(false);
// default is true
mPtrFrame.setKeepHeaderWhenRefresh(true);
