How to Animate Addition or Removal of Android ListView Rows

Animation anim = AnimationUtils.loadAnimation(
                     GoTransitApp.this, android.R.anim.slide_out_right
                 );
anim.setDuration(500);
listView.getChildAt(index).startAnimation(anim );

new Handler().postDelayed(new Runnable() {

    public void run() {

        FavouritesManager.getInstance().remove(
            FavouritesManager.getInstance().getTripManagerAtIndex(index)
        );
        populateList();
        adapter.notifyDataSetChanged();

    }

}, anim.getDuration());

for top-to-down animation use :

<set xmlns:android="http://schemas.android.com/apk/res/android">
        <translate android:fromYDelta="20%p" android:toYDelta="-20"
            android:duration="@android:integer/config_mediumAnimTime"/>
        <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
            android:duration="@android:integer/config_mediumAnimTime" />
</set>

The RecyclerView takes care of adding, removing, and re-ordering animations!

This simple AndroidStudio project features a RecyclerView. take a look at the commits:

1. commit of the classic Hello World Android app
2. commit, adding a RecyclerView to the project (content not dynamic)
3. commit, adding functionality to modify content of RecyclerView at runtime (but no animations)
4. and finally...commit adding animations to the RecyclerView
