Scale.xml Zoom Effect:


<?xml version= "1.0" encoding= "Utf-8"?>


<set xmlns:android= "Http://schemas.android.com/apk/res/android" >

</set>
<!--
interpolator Specifies an animation insert, common with an acceleration reducer accelerate_decelerate_interpolator,
Accelerate the accelerate_interpolator of the insertion device, and decelerate the Decelerate_interpolator.
Fromxscale,fromyscale, the scale of X, y before the start of the animation, 0.0 for not showing, 1.0 for normal size Toxscale,toyscale,
The multiple of the final zoom of the animation, 1.0 for normal size, greater than 1.0 to enlarge the Pivotx,pivoty animation starting position, relative to the screen percentage,
Two all 50% means that the animation starts startoffset from the middle of the screen, the interval of time that the animation executes multiple times, and if it is executed only once, the time is paused before execution.
Unit millisecond duration, an animation effect consumes time, in milliseconds, the smaller the value the faster the animation repeatcount, the animation repeats the count,
The animation will execute the value + 1 times repeatmode, the animation repeats the pattern, the reverse is reversed, and when the first even executes, the animation will be in the opposite direction.
Restart for re-execution, direction unchanged

Translate.xml Move Effect:


<?xml version= "1.0" encoding= "Utf-8"?>


<set xmlns:android= "Http://schemas.android.com/apk/res/android" >

Android:fromydelta= "480"
Android:toxdelta= "0"
Android:toydelta= "0"/>
</set>
<!--
Fromxdelta,fromydelta animation starts with the x, Y coordinates, and the lower-right corner of the screen is x:320,y:480 Toxdelta,toydelta
coordinates of x, Y at end of animation

The animation effect is defined in an XML file in the Anim directory, in a program with animationutils.loadanimation (context context,
int resourcesid) loads into a animation object, performing the Startanimation method of the view that needs to be animated when the animation effect needs to be displayed,
Incoming Animation, you can.
View view = new view (this);
Animation animation=animationutils.loadanimation (this, r.anim.translate);
View.startanimation (animation);
Xxx.addview (view);

Toggle activity can also apply animation effects, after the StartActivity method, execute the Overridependingtransition method,
Two parameters are the animation effect before switching, the animation effect after switching. Overridependingtransition only supports Android 2.0 or later.
StartActivity (Intent);


Overridependingtransition (R.ANIM.A1,R.ANIM.A2);
