Usage

1. Add layout xml fragment like below:

   <com.coco.draggablegridviewpager.DraggableGridViewPager
       android:id="@+id/draggable_grid_view_pager"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingBottom="20dp"
       android:paddingLeft="20dp"
       android:paddingRight="60dp"
       android:paddingTop="20dp" >
   
   </com.coco.draggablegridviewpager.DraggableGridViewPager>

2. Define Adapter to provide item data & view:

   private ArrayAdapter<String> mAdapter;
   
   // ...
   
   mAdapter = new ArrayAdapter<String>(this, 0) {
       @Override
       public View getView(int position, View convertView, ViewGroup parent) {
           final String text = getItem(position);
           if (convertView == null) {
               convertView = (TextView) getLayoutInflater().inflate(R.layout.draggable_grid_item, null);
           }
           ((TextView) convertView).setText(text);
           return convertView;
       }
   
   };

3. Then find the DraggableGridViewPager view install listeners to it:

   @Override
   protected void onCreate(Bundle savedInstanceState) {
       requestWindowFeature(Window.FEATURE_NO_TITLE);
       super.onCreate(savedInstanceState);
   
       setContentView(R.layout.draggable_grid_view_pager_test);
       mDraggableGridViewPager = (DraggableGridViewPager) findViewById(R.id.draggable_grid_view_pager);
   
       // ...
   
       mDraggableGridViewPager.setAdapter(mAdapter);
       mDraggableGridViewPager.setOnPageChangeListener(new OnPageChangeListener() {
           @Override
           public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
               Log.v(TAG, "onPageScrolled position=" + position + ", positionOffset=" + positionOffset
                       + ", positionOffsetPixels=" + positionOffsetPixels);
           }
   
           @Override
           public void onPageSelected(int position) {
               Log.i(TAG, "onPageSelected position=" + position);
           }
   
           @Override
           public void onPageScrollStateChanged(int state) {
               Log.d(TAG, "onPageScrollStateChanged state=" + state);
           }
       });
       mDraggableGridViewPager.setOnItemClickListener(new OnItemClickListener() {
           @Override
           public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
               showToast(((TextView) view).getText().toString());
           }
       });
       mDraggableGridViewPager.setOnItemLongClickListener(new OnItemLongClickListener() {
           @Override
           public boolean onItemLongClick(AdapterView<?> parent, View view, int position, long id) {
               showToast(((TextView) view).getText().toString() + " long clicked!!!");
               return true;
           }
       });
       mDraggableGridViewPager.setOnRearrangeListener(new OnRearrangeListener() {
           @Override
           public void onRearrange(int oldIndex, int newIndex) {
               Log.i(TAG, "OnRearrangeListener.onRearrange from=" + oldIndex + ", to=" + newIndex);
               String item = mAdapter.getItem(oldIndex);
               mAdapter.setNotifyOnChange(false);
               mAdapter.remove(item);
               mAdapter.insert(item, newIndex);
               mAdapter.notifyDataSetChanged();
           }
       });
   
       // ...
   
   }
