In Android, how to I edit views in a layout, when my setContentView is not in that layout?

For example, I might be in R.Layout.activity_main ,

but when I onCreate my activity, I want to change a TextView in another layout, so I would create a TextView object and findViewById from that layout, and then change it.

But this will not work unless I set my contentview to that layout, but is it possible to be able to set the TextView in that layout, without having to setContentView to that layout?

It is better to store a reference of desired view in a class as a variable when you create it's parent layout.Then change it's property when you need.

This does not work in all situations, but you could try a LayoutInflator.

LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.your_layout, null);

Then to find views in that layout, just do...

layout.findViewById(R.id.your_view);
