Attention Seeker Android Animation

Sometimes you would want to the user to know that some vent has occured.  I picked this animation from Cyril Mottier's post.

I am going to show how to animate a menu item on click of it. Its shake animtaion.

The below code is responsible for animtaion.

In onOptionsItemSelected get the view of the selected menu item. Then call  tada(yourview).start();

   @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle presses on the action bar items
        switch (item.getItemId()) {
        case R.id.action_launch:
            View menu_item_1 = findViewById(R.id.action_launch);
            tada(menu_item_1).start();

       return true;
       
        default:
            return super.onOptionsItemSelected(item);
        }
    }

The animation part

public static ObjectAnimator tada(View view) {
    return tada(view, 1f);
}

public static ObjectAnimator tada(View view, float shakeFactor) {

    PropertyValuesHolder pvhScaleX = PropertyValuesHolder.ofKeyframe(View.SCALE_X,
            Keyframe.ofFloat(0f, 1f),
            Keyframe.ofFloat(.1f, .9f),
            Keyframe.ofFloat(.2f, .9f),

    );

    PropertyValuesHolder pvhScaleY = PropertyValuesHolder.ofKeyframe(View.SCALE_Y,
            Keyframe.ofFloat(0f, 1f),

            Keyframe.ofFloat(.2f, .9f),

            Keyframe.ofFloat(1f, 1f)
    );

    PropertyValuesHolder pvhRotate = PropertyValuesHolder.ofKeyframe(View.ROTATION,
            Keyframe.ofFloat(0f, 0f),
            Keyframe.ofFloat(.1f, -3f * shakeFactor),
            Keyframe.ofFloat(.2f, -3f * shakeFactor),
            Keyframe.ofFloat(.3f, 3f * shakeFactor),
            Keyframe.ofFloat(.4f, -3f * shakeFactor),

            Keyframe.ofFloat(.9f, 3f * shakeFactor),
            Keyframe.ofFloat(1f, 0)
    );

    return ObjectAnimator.ofPropertyValuesHolder(view, pvhScaleX, pvhScaleY, pvhRotate).
            setDuration(1000);
}

public static ObjectAnimator nope(View view) {
    int delta = view.getResources().getDimensionPixelOffset(R.dimen.spacing_medium);

    PropertyValuesHolder pvhTranslateX = PropertyValuesHolder.ofKeyframe(View.TRANSLATION_X,
            Keyframe.ofFloat(0f, 0),
            Keyframe.ofFloat(.10f, -delta),
            Keyframe.ofFloat(.26f, delta),
            Keyframe.ofFloat(.42f, -delta),

            Keyframe.ofFloat(.74f, -delta),
            Keyframe.ofFloat(.90f, delta),
            Keyframe.ofFloat(1f, 0f)
    );

    return ObjectAnimator.ofPropertyValuesHolder(view, pvhTranslateX).
            setDuration(500);
}
