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;
         }
    
     };
    
  1. 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();
             }
         });
    
         // ...
    
     }
