belongs to Maven artifact com.android.support:asynclayoutinflater:28.0.0-alpha1
Helper class for inflating layouts asynchronously. To use, construct
an instance of
AsyncLayoutInflater on the UI thread and call
inflate(int, ViewGroup, OnInflateFinishedListener). The
AsyncLayoutInflater.OnInflateFinishedListener will be invoked on the UI thread
when the inflate request has completed.
This is intended for parts of the UI that are created lazily or in response to user interactions. This allows the UI thread to continue to be responsive & animate while the relatively heavy inflate is being performed.
For a layout to be inflated asynchronously it needs to have a parent
generateLayoutParams(AttributeSet) is thread-safe
and all the Views being constructed as part of inflation must not create
Handlers or otherwise call
myLooper(). If the
layout that is trying to be inflated cannot be constructed
asynchronously for whatever reason,
automatically fall back to inflating on the UI thread.
NOTE that the inflated View hierarchy is NOT added to the parent. It is
equivalent to calling
inflate(int, ViewGroup, boolean)
with attachToRoot set to false. Callers will likely want to call
addView(View) in the
callback at a minimum.
