Question

I have an imageview and a text view in a widget layout.
Now I need to remove the image view from the remoteview programatically.

I see that there is the api remoteView.removeAll(Viewid);

So when I do

remoteViews.removeAll(R.id.imageView);

and update the remoteView through

appwidgetmanager.updateAppVidget

nothing concrete is visible on the screen.
the imageview is still there.

Am I on the correct track?
Kindly give your suggestions on this.

Answer 1

The function removeAll is the equivalent of ViewGroup.removeAllViews. For it to work in a widget through a RemoteViews object you would need to have your ImageView wrapped within a FrameLayout. You can then call removeAll and pass the id of that FrameLayout.

Note that setting the visibility to INVISIBLE or even GONE is much easier with RemoteViews, and does not require extra Views.
