How to figure B (the Activity layout) nested into the figure A layout (fragments) in the red areas

CodePudding user response:

You can use the include tag

CodePudding user response:

I am not going to the XML file directly into fragments, I also operating in the activity, I am want to be in fragments with code to the activity layout sets in

CodePudding user response:

Directly in nested fragments bai fragments

CodePudding user response:

The first thing to understand the significance of using fragments? Previously developed each class is an Activity that quite a waste of resources? If you need to use fragments, then the APP there and only one Activity can;
The meaning of the fragments is fragmented, more to save resources, this was a fragment, you must make the Activity go in? So I think it is not necessary to use fragments, because it doesn't make any sense... Directly with the activty is worse than you, because you don't understand Frament; A pure hand, don't like do not spray;

CodePudding user response:

Activity can be realized, fragments can also realize

CodePudding user response:

Only the activity nested fragments, not the opposite

The injection or injection I met a demand for third-party libraries is the activity, want to be embedded into the now fragments
Less code

APP is, there is only an Activity can be only one or two small demo interface

CodePudding user response:

The activity can't be nested, consider also realize yourself

CodePudding user response:

TabActivity can be achieved, but it's outdated, better to let the product to change the demand again
