Android animation using xml

Step to perform animation in android apps

Step 1) Create XML which define animation
create a xml file which define the animation in  res ⇒ anim ⇒ animation.xml , If you dont have anim folder then create it in res directory

blink.xml

<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <alpha android:fromAlpha="0.0"         android:toAlpha="1.0"         android:interpolator="@android:anim/accelerate_interpolator"         android:duration="800"         android:repeatMode="reverse"         android:repeatCount="infinite"/> </set>     Step 2) Load the animation and set to view in acitvity to see blink effect public class BlinkActivity extends Activity{       TextView textMessage;       // Animation     Animation animBlink;       @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_blink);           textMessage = (TextView) findViewById(R.id.textMessage);                textMessag.setText(Welcome to Android Code Portal);         // load the animation         animBlink = AnimationUtils.loadAnimation(getApplicationContext(),                 R.anim.blink);          // start the animation        textMessage.startAnimation(animBlink);           } }   Some other useful animations as follows    1)Blink blink.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <alpha android:fromAlpha="0.0"         android:toAlpha="1.0"         android:interpolator="@android:anim/accelerate_interpolator"         android:duration="800"         android:repeatMode="reverse"         android:repeatCount="infinite"/> </set>   2)ZoomIn zoomin.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true" >       <scale         xmlns:android="http://schemas.android.com/apk/res/android"         android:duration="1000"         android:fromXScale="1"         android:fromYScale="1"         android:pivotX="50%"         android:pivotY="50%"         android:toXScale="3"         android:toYScale="3" >     </scale>   </set>    3)ZoomOut zoomout.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true" >       <scale         xmlns:android="http://schemas.android.com/apk/res/android"         android:duration="1000"         android:fromXScale="1.0"         android:fromYScale="1.0"         android:pivotX="50%"         android:pivotY="50%"         android:toXScale="0.5"         android:toYScale="0.5" >     </scale>   </set>   4)FadeIn fadein.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true" >       <alpha         android:duration="1000"         android:fromAlpha="0.0"         android:interpolator="@android:anim/accelerate_interpolator"         android:toAlpha="1.0" />   </set>    5)FadeOut fadeout.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true" >       <alpha         android:duration="1000"         android:fromAlpha="1.0"         android:interpolator="@android:anim/accelerate_interpolator"         android:toAlpha="0.0" />   </set>   6)Rotate rotate.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android">     <rotate android:fromDegrees="0"         android:toDegrees="360"         android:pivotX="50%"         android:pivotY="50%"         android:duration="700"         android:repeatMode="restart"         android:repeatCount="infinite"         android:interpolator="@android:anim/cycle_interpolator"/>   </set>   7)Move  move.xml <?xml version="1.0" encoding="utf-8"?> <set     xmlns:android="http://schemas.android.com/apk/res/android"     android:interpolator="@android:anim/linear_interpolator"     android:fillAfter="true">      <translate         android:fromXDelta="0%p"         android:toXDelta="80%p"         android:duration="1000" /> </set>   8)SlideDown slidedown.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true">       <scale         android:duration="800"         android:fromXScale="1.0"         android:fromYScale="0.0"         android:interpolator="@android:anim/linear_interpolator"         android:toXScale="1.0"         android:toYScale="1.0" />   </set>    9)SlideUp slideup.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true" >       <scale         android:duration="800"         android:fromXScale="1.0"         android:fromYScale="1.0"         android:interpolator="@android:anim/linear_interpolator"         android:toXScale="1.0"         android:toYScale="0.0" />   </set>   10)Bounce  bounce.xml <?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android"     android:fillAfter="true"     android:interpolator="@android:anim/bounce_interpolator">       <scale         android:duration="800"         android:fromXScale="1.0"         android:fromYScale="0.0"         android:toXScale="1.0"         android:toYScale="1.0" />   </set>
