Android-DraggableGridViewPager

• 项目地址： https://github.com/zzhouj/Android-DraggableGridViewPager

  介绍：

  仿zaker效果的拖拽排序。可以动态设置列数，动态增加或者减少item，当一页填满自动增加到下一页，当页数大于1，可以左右翻页。

  运行效果：

使用说明：

xml：

1 2 3 4 5 6 7 8 9 10

<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>

定义adapter：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

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;     }   };

添加Listener：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56

@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();         }     });       // ...   }
