Am adding this answer for the purpose of those who google about this..

There was an episode of DevBytes (<a href="https://www.youtube.com/watch?v=_BZIvjMgH-Q" rel="noreferrer">ListView Cell Dragging and Rearranging</a>) recently which explains how to do this 

You can find it <a href="https://www.youtube.com/watch?v=_BZIvjMgH-Q" rel="noreferrer">here</a> also the sample code is available <a href="http://developer.android.com/shareables/devbytes/ListViewDraggingAnimation.zip" rel="noreferrer">here</a>.

What this code basically does is that it creates a <code>dynamic listview</code> by the extension of <code>listview</code> that supports cell dragging and swapping. So that you can use the <code>DynamicListView</code> instead of your basic <code>ListView</code> and that's it you have implemented a ListView with Drag and Drop.

The DragListView lib does this really neat with very nice support for custom animations such as elevation animations. It is also still maintained and updated on a regular basis.

Here is how you use it:

1: Add the lib to gradle first

<pre><code>dependencies {
 compile 'com.github.woxthebox:draglistview:1.2.1'
}
</code></pre>

2: Add list from xml

<pre><code>&lt;com.woxthebox.draglistview.DragListView
 android:id="@+id/draglistview"
 android:layout_width="match_parent"
 android:layout_height="match_parent"/&gt;
</code></pre>

3: Set the drag listener

<pre><code>mDragListView.setDragListListener(new DragListView.DragListListener() {
 @Override
 public void onItemDragStarted(int position) {
 }

 @Override
 public void onItemDragEnded(int fromPosition, int toPosition) {
 }
});
</code></pre>

4: Create an adapter overridden from DragItemAdapter

<pre><code>public class ItemAdapter extends DragItemAdapter&lt;Pair&lt;Long, String&gt;, ItemAdapter.ViewHolder&gt;
 public ItemAdapter(ArrayList&lt;Pair&lt;Long, String&gt;&gt; list, int layoutId, int grabHandleId, boolean dragOnLongPress) {
 super(dragOnLongPress);
 mLayoutId = layoutId;
 mGrabHandleId = grabHandleId;
 setHasStableIds(true);
 setItemList(list);
}
</code></pre>

5: Implement a viewholder that extends from DragItemAdapter.ViewHolder

<pre><code>public class ViewHolder extends DragItemAdapter.ViewHolder {
 public TextView mText;

 public ViewHolder(final View itemView) {
 super(itemView, mGrabHandleId);
 mText = (TextView) itemView.findViewById(R.id.text);
 }

 @Override
 public void onItemClicked(View view) {
 }

 @Override
 public boolean onItemLongClicked(View view) {
 return true;
 }
}
</code></pre>

Now it's pretty easy to implement for <code>RecyclerView</code> with <a href="http://developer.android.com/reference/android/support/v7/widget/helper/ItemTouchHelper.html" rel="noreferrer">ItemTouchHelper</a>. Just override <code>onMove</code> method from <code>ItemTouchHelper.Callback</code>:

<pre><code> @Override
public boolean onMove(RecyclerView recyclerView, RecyclerView.ViewHolder viewHolder, RecyclerView.ViewHolder target) {
 mMovieAdapter.swap(viewHolder.getAdapterPosition(), target.getAdapterPosition());
 return true;
}
</code></pre>

Pretty good tutorial on this can be found at medium.com : <a href="https://medium.com/@ipaulpro/drag-and-swipe-with-recyclerview-b9456d2b1aaf#.u7416aupw" rel="noreferrer">Drag and Swipe with RecyclerView</a>

I have a list of records in a listview that I want the user to be able to re-sort using a drag and drop method. I have seen this implemented in other apps, but I have not found a tutorial for it. It must be something that others need as well. Can anyone point me to some code for doing this?

Android List View Drag and Drop sort

我在列表视图中有一个记录列表，希望用户能够使用拖放方法对其进行重新排序。我已经在其他应用程序中看到了这一点，但我还没有找到针对它的教程。它必须是其他人也需要的东西。有没有人能给我指点一些这样做的代码？
