Object Animation

DevBytes: Property Animations new animation system since 3.0:

For source code see the video:

Animator anim = AnimatorInflater.loadAnimator(PropertyAnimations.this, animationID);
anim.setTarget(v);
anim.start();

<set xmlns:android="http://schemas.android.com/apk/res/android">
  <objectAnimator
      android:propertyName="scaleX"
      android:repeatCount="1"
      android:repeatMode="reverse"
      android:duration="300"
      android:valueTo="2"/>
  <objectAnimator
      android:propertyName="scaleY"
      android:repeatCount="1"
      android:repeatMode="reverse"
      android:duration="300"
      android:valueTo="2"/>
</set>

Window Animations

From DevBytes: Window Animations, for Window animations use the older View Animation API.

• Translate animation

• Scale animation (with the current API, we cannot scale back)

Sample

Download source code from DevBytes: Window Animations

Slide the next activity in as we slide this activity out:

Intent subActivity = new Intent(WindowAnimations.this,
        AnimatedSubActivity.class);
// The enter/exit animations for the two activities are specified by xml resources
Bundle translateBundle =
        ActivityOptions.makeCustomAnimation(WindowAnimations.this,
        R.anim.slide_in_left, R.anim.slide_out_left).toBundle();
startActivity(subActivity, translateBundle);

Scale up the new activity from a given bitmap, cross-fading between the starting and ending representations

BitmapDrawable drawable = (BitmapDrawable) thumbnail.getDrawable();
Bitmap bm = drawable.getBitmap();
Intent subActivity = new Intent(WindowAnimations.this, AnimatedSubActivity.class);
Bundle scaleBundle = ActivityOptions.makeThumbnailScaleUpAnimation(
        thumbnail, bm, 0, 0).toBundle();
startActivity(subActivity, scaleBundle);
