Use theme to customize the activity to exit the animation

Do you think the default animation of an activity is too fast or ugly ..
I used activity. overridependingtransition to customize the animation for entering the activity, but I found that the animation for exiting cannot be defined. The results show the powerful theme and style, and you need to study it later.

Specifically, this is the case:
In androidmanifest, you can define the theme attribute for the application and activity labels. If an attribute is defined for the application, it will affect all the activities. Of course, you can overwrite it in the activity.

<Application Android: theme = "@ style/themeactivity">

Then in values/themes. xml

<Style name = "themeactivity" mce_bogus = "1">
<Item name = "Android: windowanimationstyle"> @ style/animationactivity </item>
<Item name = "Android: windownotitle"> true </item>
</Style>

In values/styles. xml

<Style name = "animationactivity" parent = "@ Android: style/animation. Activity" mce_bogus = "1">
<Item name = "Android: activityopenenteranimation"> @ anim/push_left_in </item>
<Item name = "Android: activityopenexitanimation"> @ anim/push_left_out </item>
<Item name = "Android: activitycloseenteranimation"> @ anim/push_right_in </item>
<Item name = "Android: activitycloseexitanimation"> @ anim/push_right_out </item>
</Style>

In this way, you can define the animation in anim. This is the same as the normal animation. If you do not know it, see

Http://developer.android.com/guide/topics/graphics/view-animation.html.

In addition to defining the animation of an activity, you can also define the animation of a task and window. For details, see
