[ACCEPTED]-Is there any difference between getLayoutInflater() and .getSystemService(Context.LAYOUT_INFLATER_SERVICE)-android-widget
No
As long as the Activity or Window that 5 calls getLayoutInflater()
has the same Context that would call 4 getSystemService()
, there is no difference.
Proof You can trace 3 the LayoutInflater returned by getLayoutInflater()
to LayoutInflater.from() and 2 you can see this is just a shortcut for 1 getSystemService()
from the source code:
public static LayoutInflater from(Context context) {
LayoutInflater LayoutInflater =
(LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
if (LayoutInflater == null) {
throw new AssertionError("LayoutInflater not found.");
}
return LayoutInflater;
}
There is at least one situation that only 10
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
must 9 be used instead of the counterpart
getLayoutInflater
That 8 situation is in an arbitrary object class. For 7 example, I have an instance of class call 6 objectA. In objectA, I want to inflate a 5 view onto the parent view (happen in ArrayAdapter 4 that inflates customized row on the its 3 listview.) In this case, context.getLayoutInflater does not work 2 since there is no activity or windows associated 1 with the context. Only getSystemService(Context.LAYOUT_INFLATER_SERVICE) is appropriate then.
This is how you define a LayoutInflater.
LayoutInflater inflater = (LayoutInflater)context.getSystemService (Context.LAYOUT_INFLATER_SERVICE);
And 8 getLayoutInflater()
just gives "quick access to the LayoutInflater 7 instance that the window retrieved from 6 its Context" (from the documentation) by returning 5 the LayoutInflater.
Similarly, getSystemService(Context.LAYOUT_INFLATER_SERVICE)
is used 4 to retrieve a LayoutInflater for inflating 3 layout resources in this context.
So, actually 2 there is NO difference between the two.

NO.
There is no difference at all.
