    <p>I am using Drag n Drop in my list view.Its working very fine but the problem is how i change the order of elements after dragging too.Suppose i have a list view with elements 1 at 0 position, 2 at 1 position 3 at 2 position and so on. So when i click on the item at position 2 it is giving me item at position 1 and it is right too but after dragging suppose i replace 2 by 1.it should give me data that is associated with 1 but it is again giving me data of 2.so how it is possible.any help would be appreciated.</p> <p>here is my code:</p> <pre><code>public class DragNDropListActivity extends ListActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.dragndroplistview); Button mbtn=(Button)findViewById(R.id.button12); mbtn.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent i=new Intent(DragNDropListActivity.this,FormulaActivity.class); startActivity(i); finish(); } }); ArrayList&lt;String&gt; content = new ArrayList&lt;String&gt;(mListContent.length); for (int i=0; i &lt; mListContent.length; i++) { content.add(mListContent[i]); } setListAdapter(new DragNDropAdapter(this, new int[]{R.layout.dragitem}, new int[] {R.id.TextView01}, content));//new DragNDropAdapter(this,content) ListView listView = getListView(); if (listView instanceof DragNDropListView) { ((DragNDropListView) listView).setDropListener(mDropListener); ((DragNDropListView) listView).setRemoveListener(mRemoveListener); ((DragNDropListView) listView).setDragListener(mDragListener); } } private DropListener mDropListener = new DropListener() { public void onDrop(int from, int to) { ListAdapter adapter = getListAdapter(); if (adapter instanceof DragNDropAdapter) { ((DragNDropAdapter)adapter).onDrop(from, to); getListView().invalidateViews(); } } }; private RemoveListener mRemoveListener = new RemoveListener() { public void onRemove(int which) { ListAdapter adapter = getListAdapter(); if (adapter instanceof DragNDropAdapter) { ((DragNDropAdapter)adapter).onRemove(which); getListView().invalidateViews(); } } }; private DragListener mDragListener = new DragListener() { int backgroundColor = 0xe0103000; public void onDrag(int x, int y, ListView listView) { // TODO Auto-generated method stub } public void onStartDrag(View itemView) { itemView.setVisibility(View.INVISIBLE); itemView.setBackgroundColor(backgroundColor); ImageView iv = (ImageView)itemView.findViewById(R.id.ImageView01); if (iv != null) iv.setVisibility(View.VISIBLE); } public void onStopDrag(View itemView) { itemView.setVisibility(View.VISIBLE); itemView.setBackgroundColor(backgroundColor); ImageView iv = (ImageView)itemView.findViewById(R.id.ImageView01); if (iv != null) iv.setVisibility(View.VISIBLE); } }; private static String[] mListContent={"1","2","3"}; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
