Is there a way to "swap" out a view at runtime? Here's my goal: I want to display an animated, indeterminate ProgressBar
view until my image is loaded. Is there a way to do this easily, without having to do a bunch of crazy stuff? Is there a way I can get the resource ID of the ProgressBar
spinner animation and simply reuse that?
Yes. I tend to make a FrameLayout
which contains both an ImageView
and a ProgressBar
. In onCreate()
I do imageView.setVisibility(View.INVISIBLE)
and then once the image loads I do:
progress.setVisibility(View.INVISIBLE);
imageView.setVisibility(View.VISIBLE);
In terms of the threading you should as always use AsyncTask
. This is easily the most complicated part of the process, although still quite manageable. Check out this answer for a full code listing.
