How would one change the
android:src XML property programatically of a FloatingActionButton or Button widget? I have a button defined as following within an activity:
FloatingActionButton floatingActionButton = (FloatingActionButton) this.findViewById(R.id.start_button);
It has an initial
android:src set as follows:
I’m trying to utilize the setImageResource(int id) to change the
android:src XML property, but how to I access a Drawable icon such as
ic_media_pause after a button click that occurs for example. When I try to pass in
R.drawable.ic_media_pause to the
setImageResource() method I received an cannot resolve symbol error.
How do I get at the available R.drawable resources to pass it in as an argument.
Any help would be great appreciated. Thank you!
You’re trying to access a default icon included in the SDK. You need to prefix your resource identifier with “android.” For example:
this will allow you to reference the default icons.
