Scale & Translate animation

问题

I require an animation for an image in my application. The image should start coming from the top left corner till the middle of screen. The image size will be smaller at the initial stage. While coming to the middle of the screen, its size should increase(i.e. scaling should take place). Image should not go back to its original position. It should be placed at the middle of the screen itself after the animation.

Can anyone please help.

Please find the answer here. Create an xml inside /res/anim folder and put the below code into it.

<?xml version="1.0" encoding="utf-8"?> 
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/linear_interpolator">
   <scale android:fromXScale="0.0" android:fromYScale="0.0"
          android:toXScale="1.0" android:toYScale="1.0" 
          android:duration="700" android:fillBefore="false" />
   <translate android:fromXDelta="-200" android:fromYDelta="-200"
          android:duration="700" />
</set>

Place the below code inside the java file:

Animation logoMoveAnimation = AnimationUtils.loadAnimation(this, R.anim.logoanimation); 
logoIV.startAnimation(logoMoveAnimation);

logoanimation is the name of my animation xml file.

Thanks for all those who tried out for my question.
