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(; // ... 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(); } }); // ... } License ======= The MIT License (MIT) Copyright (c) 2014 justin Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
