<!-- 设置整个刷新列表的背景色 -->
<attr name="ptrRefreshableViewBackground" format="reference|color" />
<!-- A drawable to use as the background of the Header and Footer Loading Views -->
<!-- 设置下拉Header或者上拉Footer的背景色 -->
<attr name="ptrHeaderBackground" format="reference|color" />
<!-- Text Color of the Header and Footer Loading Views -->
<!-- 用于设置Header与Footer中文本的颜色 -->
<attr name="ptrHeaderTextColor" format="reference|color" />
<!-- Text Color of the Header and Footer Loading Views Sub Header -->

</attr>
<!-- Whether the Indicator overlay(s) should be used -->
<!-- 如果为true会在mPullRefreshListView中出现icon，右上角和右下角，挺有意思的 -->
<attr name="ptrShowIndicator" format="reference|boolean" />
<!-- Drawable to use as Loading Indicator. Changes both Header and Footer. -->
<!-- 同时改变头部和底部的图标 -->
<attr name="ptrDrawable" format="reference" />
<!-- Drawable to use as Loading Indicator in the Header View. Overrides value set in ptrDrawable. -->

</attr>
<!-- Whether the user can scroll while the View is Refreshing -->
<!-- 刷新的时候，是否允许ListView或GridView滚动 -->
<attr name="ptrScrollingWhileRefreshingEnabled" format="reference|boolean" />
<!--
Whether PullToRefreshListView has it‘s extras enabled. This allows the user to be
able to scroll while refreshing, and behaves better. It acheives this by adding
Header and/or Footer Views to the ListView.
-->
<!-- 决定了Header，Footer以何种方式加入mPullRefreshListView，true为headView方式加入，就是滚动时刷新头部会一起滚动 -->
<attr name="ptrListViewExtrasEnabled" format="reference|boolean" />
<!--
Whether the Drawable should be continually rotated as you pull. This only
takes effect when using the ‘Rotate‘ Animation Style.
-->
<attr name="ptrRotateDrawableWhilePulling" format="reference|boolean" />

<attr name="ptrAdapterViewBackground" format="reference|color" />
<attr name="ptrDrawableTop" format="reference" />

</declare-styleable>
</resources>
可以在布局文件中设置自定义的这些样式，使用方法如下：
<com.handmark.pulltorefresh.libaray xmlns:ptr="http://schemas.android.com/apk/res-auto"
android:id="@+id/lv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white"
android:cacheColorHint="#00000000"
android:divider="@drawable/border"
android:fadingEdge="none"
android:fadingEdgeLength="0dip"
android:scrollbars="none"
android:scrollingCache="true"
ptr:ptrDrawable="@drawable/infzm_logo"
/>
注意：需要声明命名空间：xmlns:ptr=http://schemas.android.com/apk/res-auto
使用自定义属性：ptr:ptrDrawable="@drawable/logo"
其他属性使用方法类似。
