I have a requirement in which i have to give zoom out effect in splash screen. Please Suggest something. I have an idea that we can 开发者_如何学Ckeep its animation in res/anim folder and use it in activity.
Use this in Activity Java File :
FrameLayout mainFrame = ((FrameLayout) findViewById(R.id.FrameLayout01));
Animation hyperspaceJumpAnimation = AnimationUtils.loadAnimation(this,
R.anim.hyperspace_jump);
mainFrame.startAnimation(hyperspaceJumpAnimation);
Put this code under res > anim > hyperspace_jump.xml
<?xml version="1.0" encoding="UTF-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" android:shareInterpolator="false">
<scale
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXScale="0.0"
android:toXScale="1.4"
android:fromYScale="0.0"
android:toYScale="1.4"
android:pivotX="50%"
android:pivotY="50%"
android:fillAfter="false"
android:duration="700" />
<set android:interpolator="@android:anim/decelerate_interpolator">
<scale
android:fromXScale="1.4"
android:toXScale="0.8"
android:fromYScale="1.4"
android:toYScale="0.8"
android:pivotX="50%"
android:pivotY="50%"
android:startOffset="700"
android:duration="400"
android:fillBefore="false" />
<!-- <rotate
android:fromDegrees="0"
android:toDegrees="360"
android:toYScale="0.0"
android:pivotX="50%"
android:pivotY="50%"
android:startOffset="700"
android:duration="400" />
-->
</set>
</set>
yu can use the view animation in order to get the zoom effect.
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<alpha android:fromAlpha="0.0"
android:toAlpha="1.0" android:duration="900">
</alpha>
<set
android:interpolator="@android:anim/accelerate_interpolator"
android:startOffset="700">
<scale
android:fromXScale="0"
android:toXScale="1"
android:fromYScale="0"
android:toYScale="1.0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="1000"
android:fillBefore="false"
/>
</set>
</set>
create an XML file in the animation folder under resource.And in the java file you must set the animation for the respective image.
Animation hyperspaceJump = AnimationUtils.loadAnimation(this, R.anim.hyperspace_jump);
image.startAnimation(hyperspaceJump);
Here my xml file name is hyperspace_jump.for more reference click here.
