What are the actual ms time values for Android'

问题:

Android includes

config_longAnimTime
config_mediumAnimTime
config_shortAnimTime

but the actual values identified by these constants don't make sense as milliseconds. I'm sure they get compiled into useful values, and I can determine them with code, but I'm sure someone else knows the answer - and, more to the point, I'm sure other people will be looking for them. So please post the actual values as an answer and save everyone a little bit of time.

回答1:

Current values (since 3.x):

• config_shortAnimTime=200
• config_mediumAnimTime=400
• config_longAnimTime=500

And the duration of the activity open/close and fragment open/close animations:

• config_activityShortDur=150
• config_activityDefaultDur=220

回答2:

Here we go:

config_longAnimTime   = 400
config_mediumAnimTime = 300
config_shortAnimTime  = 150

回答3:

Directly read the property:

getResources().getInteger(android.R.integer.config_shortAnimTime);
getResources().getInteger(android.R.integer.config_mediumAnimTime);
getResources().getInteger(android.R.integer.config_longAnimTime);

For anyone using java code for create and start animation.
The default duration for a animation is 300

public class ValueAnimator extends Animator implements AnimationHandler.AnimationFrameCallback {
    ...
    // How long the animation should last in ms
    private long mDuration = 300;
}
