Bauerca drag-sort-listview simple example

Question

Bauerca drag-sort-listview is an amazing library for the drag functionality in a list view.. https://github.com/bauerca/drag-sort-listview

BUT my problem is that the demo project is pretty complex, I cant track it to include the functionality in my project..

Any simple example would be appreciated..

For example I just need a screen with this custom list that contains three items.. Or any other simple example..

Thank you

Here's a short program of how to use the library that I just managed to write myself. Basically it's the same thing as the sample, just all in one place.

package com.example.dndlist;  import java.util.ArrayList; import java.util.Arrays;  import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.widget.ArrayAdapter;   import com.mobeta.android.dslv.DragSortController; import com.mobeta.android.dslv.DragSortListView;  public class MainActivity extends Activity {      DragSortListView listView;     ArrayAdapter<String> adapter;      private DragSortListView.DropListener onDrop = new DragSortListView.DropListener()     {         @Override         public void drop(int from, int to)         {             if (from != to)             {                 String item = adapter.getItem(from);                 adapter.remove(item);                 adapter.insert(item, to);             }         }     };      private DragSortListView.RemoveListener onRemove = new DragSortListView.RemoveListener()     {         @Override         public void remove(int which)         {             adapter.remove(adapter.getItem(which));         }     };       @Override     protected void onCreate(Bundle savedInstanceState)     {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);          listView = (DragSortListView) findViewById(R.id.listview);         String[] names = getResources().getStringArray(R.array.random_names);         ArrayList<String> list = new ArrayList<String>(Arrays.asList(names));         adapter = new ArrayAdapter<String>(this,                 R.layout.item_layout, R.id.textView1, list);         listView.setAdapter(adapter);         listView.setDropListener(onDrop);         listView.setRemoveListener(onRemove);          DragSortController controller = new DragSortController(listView);         controller.setDragHandleId(R.id.imageView1);                 //controller.setClickRemoveId(R.id.);         controller.setRemoveEnabled(false);         controller.setSortEnabled(true);         controller.setDragInitMode(1);                 //controller.setRemoveMode(removeMode);          listView.setFloatViewManager(controller);         listView.setOnTouchListener(controller);         listView.setDragEnabled(true);     }      @Override     public boolean onCreateOptionsMenu(Menu menu)     {         // Inflate the menu; this adds items to the action bar if it is present.         getMenuInflater().inflate(R.menu.main, menu);         return true;     } } 

layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:dslv="http://schemas.android.com/apk/res/com.example.dndlist" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" >  <com.mobeta.android.dslv.DragSortListView     android:id="@+id/listview"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_margin="10dp"     android:dividerHeight="5dp"     android:paddingBottom="0dp"     android:paddingLeft="10dp"     android:paddingTop="0dp"     dslv:collapsed_height="2dp"     dslv:drag_enabled="true"     dslv:drag_handle_id="@drawable/drag_handle"      dslv:drag_scroll_start="0.33"     dslv:drag_start_mode="onMove"     dslv:float_alpha="0.6"     dslv:max_drag_scroll_speed="0.5"     dslv:remove_enabled="true"     dslv:remove_mode="flingRemove"     dslv:slide_shuffle_speed="0.3"     dslv:sort_enabled="true"     dslv:track_drag_sort="false"     dslv:use_default_controller="true" /> </RelativeLayout>
