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:

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

Take a look at the Google solution. Here is a deletion method only.

ListViewRemovalAnimation project code and Video demonstration

It needs Android 4.1+ (API 16). But we have 2014 outside.

Since ListViews are highly optimized i think this is not possible to accieve. Have you tried to create your "ListView" by code (ie by inflating your rows from xml and appending them to a LinearLayout) and animate them?

Have you considered animating a sweep to the right? You could do something like drawing a progressively larger white bar across the top of the list item, then removing it from the list. The other cells would still jerk into place, but it'd better than nothing.

call listView.scheduleLayoutAnimation(); before changing the list

I hacked together another way to do it without having to manipulate list view. Unfortunately, regular Android Animations seem to manipulate the contents of the row, but are ineffectual at actually shrinking the view. So, first consider this handler:

private Handler handler = new Handler() {
@Override
public void handleMessage(Message message) {
    Bundle bundle = message.getData();

    View view = listView.getChildAt(bundle.getInt("viewPosition") - 
        listView.getFirstVisiblePosition());

    int heightToSet;
    if(!bundle.containsKey("viewHeight")) {
        Rect rect = new Rect();
        view.getDrawingRect(rect);
        heightToSet = rect.height() - 1;
    } else {
        heightToSet = bundle.getInt("viewHeight");
    }

    setViewHeight(view, heightToSet);

    if(heightToSet == 1)
        return;

    Message nextMessage = obtainMessage();
    bundle.putInt("viewHeight", (heightToSet - 5 > 0) ? heightToSet - 5 : 1);
    nextMessage.setData(bundle);
    sendMessage(nextMessage);
}

Add this collection to your List adapter:

private Collection<Integer> disabledViews = new ArrayList<Integer>();

and add

public boolean isEnabled(int position) {
   return !disabledViews.contains(position);
}

Next, wherever it is that you want to hide a row, add this:

Message message = handler.obtainMessage();
Bundle bundle = new Bundle();
bundle.putInt("viewPosition", listView.getPositionForView(view));
message.setData(bundle);
handler.sendMessage(message);    
disabledViews.add(listView.getPositionForView(view));

That's it! You can change the speed of the animation by altering the number of pixels that it shrinks the height at once. Not real sophisticated, but it works!

After inserting new row to ListView, I just scroll the ListView to new position.

ListView.smoothScrollToPosition(position);

I haven't tried it but it looks like animateLayoutChanges should do what you're looking for. I see it in the ImageSwitcher class, I assume it's in the ViewSwitcher class as well?

Since Android is open source, you don't actually need to reimplement ListView's optimizations. You can grab ListView's code and try to find a way to hack in the animation, you can also open a feature request in android bug tracker (and if you decided to implement it, don't forget to contribute a patch).

FYI, the ListView source code is here.

Here's the source code to let you delete rows and reorder them.

A demo APK file is also available. Deleting rows is done more along the lines of Google's Gmail app that reveals a bottom view after swiping a top view. The bottom view can have an Undo button or whatever you want.

As i had explained my approach in my site i shared the link.Anyways the idea is create bitmaps by getdrawingcache .have two bitmap and animate the lower bitmap to create the moving effect

Please see the following code:

listView.setOnItemClickListener(new AdapterView.OnItemClickListener()
    {
        public void onItemClick(AdapterView<?> parent, View rowView, int positon, long id)
        {
            listView.setDrawingCacheEnabled(true);
            //listView.buildDrawingCache(true);
            bitmap = listView.getDrawingCache();
            myBitmap1 = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), rowView.getBottom());
            myBitmap2 = Bitmap.createBitmap(bitmap, 0, rowView.getBottom(), bitmap.getWidth(), bitmap.getHeight() - myBitmap1.getHeight());
            listView.setDrawingCacheEnabled(false);
            imgView1.setBackgroundDrawable(new BitmapDrawable(getResources(), myBitmap1));
            imgView2.setBackgroundDrawable(new BitmapDrawable(getResources(), myBitmap2));
            imgView1.setVisibility(View.VISIBLE);
            imgView2.setVisibility(View.VISIBLE);
            RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
            lp.setMargins(0, rowView.getBottom(), 0, 0);
            imgView2.setLayoutParams(lp);
            TranslateAnimation transanim = new TranslateAnimation(0, 0, 0, -rowView.getHeight());
            transanim.setDuration(400);
            transanim.setAnimationListener(new Animation.AnimationListener()
            {
                public void onAnimationStart(Animation animation)
                {
                }

                public void onAnimationRepeat(Animation animation)
                {
                }

                public void onAnimationEnd(Animation animation)
                {
                    imgView1.setVisibility(View.GONE);
                    imgView2.setVisibility(View.GONE);
                }
            });
            array.remove(positon);
            adapter.notifyDataSetChanged();
            imgView2.startAnimation(transanim);
        }
    });

Thanks.

I have done something similar to this. One approach is to interpolate over the animation time the height of the view over time inside the rows onMeasure while issuing requestLayout() for the listView. Yes it may be be better to do inside the listView code directly but it was a quick solution (that looked good!)

Just sharing another approach:

First set the list view's android:animateLayoutChanges to true:

<ListView
        android:id="@+id/items_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:animateLayoutChanges="true"/>

Then I use a handler to add items and update the listview with delay:

Handler mHandler = new Handler();
    //delay in milliseconds
    private int mInitialDelay = 1000;
    private final int DELAY_OFFSET = 1000;


public void addItem(final Integer item) {
    mHandler.postDelayed(new Runnable() {
        @Override
        public void run() {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    mDataSet.add(item);
                    runOnUiThread(new Runnable() {
                        @Override
                        public void run() {
                            mAdapter.notifyDataSetChanged();
                        }
                    });
                }
            }).start();

        }
    }, mInitialDelay);
    mInitialDelay += DELAY_OFFSET;
}
