Android L - Material design on SwipeRefreshLayout color scheme

Question

I´m starting to implement the Material Theme on my newest project, preparing it for the launch of the new L version.

I´ve been reading the Material design guidelines and

Answer 1

The Material design spec has been updated with the new guidelines for the swipe to refresh pattern.

As of revision 21 of the support library, SwipeRefreshLayout now displays a circular indicator.
When you start swiping down, the indicator has an arrow (which suggests refreshing). When you release it, it loses the arrow and starts spinning.

Now we can still set a color scheme and the progress bar will cycle between the colors.

So which colors should we use?

Let's take a look at the Google I/O source code:

mSwipeRefreshLayout.setColorSchemeResources(
                R.color.refresh_progress_1,
                R.color.refresh_progress_2,
                R.color.refresh_progress_3);

And here are the colors:

<color name="refresh_progress_1">@color/theme_accent_2</color>
<color name="refresh_progress_2">@color/theme_accent_1</color>
<color name="refresh_progress_3">@color/theme_primary</color>

So yes, it is a mix between the primary and the accent colors.

Answer 2

Given solution did not work for me.

I simple extended and used this instead.

class SwipeToRefreshLayout(context: Context, attrs: AttributeSet): SwipeRefreshLayout(context, attrs)  {

var listener: OnRefreshListener? = null

fun setRefreshing(refreshing: Boolean, fireCallback: Boolean) {
    super.setRefreshing(refreshing)
    listener?.onRefresh()
}

override fun setOnRefreshListener(listener: OnRefreshListener?) {
    super.setOnRefreshListener(listener)
    this.listener = listener
}
}

I hope someone finds it helpful.
