Scaling Animation In ANDROID

Scaling animation is used to scale a view. In Android, you can apply this scaling effect to almost anything, from simple text, to images, buttons, etc…

 Here simply I will explain a scaling textview which you can apply to other views also... In res/anim/scale.xml

 
<?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:toXScale="1.0"
    android:fromYScale="0.0"
    android:toYScale="1.0"
    android:pivotX="50%"
    android:pivotY="50%"
    android:duration="2000" />
 </set>

Java source code is given below

 
public class Textviewanimation extends Activity {
 Animation fadeIn,fadeOut;
 TextView tv;
 Button startanimation;
 
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_textviewanimation);
        
        tv=(TextView) findViewById(R.id.textview);
        startanimation=(Button) findViewById(R.id.button1);
        tv.setText("This is an animated textview");
  
  final Animation Scale = AnimationUtils.loadAnimation(this,R.anim.scale);  
  startanimation.setOnClickListener(new OnClickListener() {
   @Override
   public void onClick(View arg0) {
    tv.startAnimation(Scale);    
   }
  });    }
     }
