Make a custom SwipeRefreshLayout Indicator?

Question

How would I go about making a custom indicator that would use a drawable object with a custom animation for the SwipeRefreshLayout?

I looked over the source code for SwipeRefreshLayout and I noticed the CircleImageView object was private.

Is there anyway to modify the ImageView?

Answer 1

You can change the drawable via reflection, not sure how good this idea is. Something like :

mSwipeRefreshLayout = (SwipeRefreshLayout)findViewById(R.id.your_swiperefresh_id);
try {
    Field f = mSwipeRefreshLayout.getClass().getDeclaredField("mCircleView");
    f.setAccessible(true);
    ImageView img = (ImageView)f.get(mSwipeRefreshLayout);
    img.setImageResource(R.drawable.your_drawable_file);
} catch (NoSuchFieldException e) {
    e.printStackTrace();
} catch (IllegalAccessException e) {
    e.printStackTrace();
}
