问题描述

当使用组合SwipeRefreshLayout与叠加模式的ActionBar，加载动画将在动作条的背后显示的，使得它几乎看不见。

When using a SwipeRefreshLayout in combination with a overlay mode ActionBar, the loading animation will be displayed behind the actionbar, making it almost invisible.

有什么我可以做，以显示它在动作条的顶部？

Is there anything I can do to show it on top of the actionbar?

推荐答案

在材料设计版本appcompat-V7库（v21.0.0）的， SwipeRefreshLayout 得到一个方法来设置进度视图偏移。

In the Material Design version of the appcompat-v7 library (v21.0.0), SwipeRefreshLayout gets a method to set the Progress View offset.

公共无效 setProgressViewOffset （布尔规模，诠释开始，诠释完）

public void setProgressViewOffset (boolean scale, int start, int end)

刷新指示器起始和休息位置总是位于靠近清爽内容的顶部。这个位置是一致的位置，但是可以基于是否有一个工具栏或动作条present在任一方向进行调整。

The refresh indicator starting and resting position is always positioned near the top of the refreshing content. This position is a consistent location, but can be adjusted in either direction based on whether or not there is a toolbar or actionbar present.

参数

比例的设置为true，如果没有视图在一个更高的Z顺序比在该进度微调器设置出现。

结束的的以像素为单位，从这一观点在此进度微调应该停下来成功轻扫手势之后的顶偏。
