最火Android开源项目DynamicGridView使用 2 | 3 | 开源项目地址:[https://github.com/open-android/DynamicGridView](https://github.com/open-android/DynamicGridView) 4 | 5 | # 运行效果 6 | ![](http://upload-images.jianshu.io/upload_images/4037105-df28bfd516527207.gif?imageMogr2/auto-orient/strip) 7 | 8 | * 爱生活,爱学习,更爱做代码的搬运工,分类查找更方便请下载黑马助手app 9 | 10 | 11 | ![黑马助手.png](http://upload-images.jianshu.io/upload_images/4037105-f777f1214328dcc4.png?imageMogr2/auto-orient/strip%7CimageView2/2/w/1240) 12 | 13 | ## 使用步骤 14 | ### 1. 在project的build.gradle添加如下代码(如下图) 15 | 16 | allprojects { 17 | repositories { 18 | ... 19 | maven { url "https://jitpack.io" } 20 | } 21 | } 22 | 23 | ![](http://oi5nqn6ce.bkt.clouddn.com/itheima/booster/code/jitpack.png) 24 | 25 | ### 2. 在Module的build.gradle添加依赖 26 | 27 | compile 'com.github.open-android:DynamicGridView:0.1.0' 28 | 29 | ### 3. 复制如下代码到xml 30 | 31 | 37 | 38 | 39 | ### 4. 复制如下代码到Activity 40 | 41 | 42 | gridView = (DynamicGridView) findViewById(R.id.dynamic_grid); 43 | // 第一个参数：上下文 44 | // 第二个参数：adapter展示需要用到的集合数据 45 | // 第三个参数：gridview一共有多少列 46 | gridView.setAdapter(new MyDynamicGridAdapter(this, itemsList, 3)); 47 | gridView.setOnDragListener(new DynamicGridView.OnDragListener() { 48 | @Override 49 | public void onDragStarted(int position) { 50 | Log.d(TAG, "drag started at position " + position); 51 | } 52 | 53 | @Override 54 | public void onDragPositionsChanged(int oldPosition, int newPosition) { 55 | Log.d(TAG, String.format("drag item position changed from %d to %d", oldPosition, newPosition)); 56 | } 57 | }); 58 | gridView.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { 59 | @Override 60 | public boolean onItemLongClick(AdapterView parent, View view, int position, long id) { 61 | gridView.startEditMode(position); 62 | return true; 63 | } 64 | }); 65 | 66 | gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 67 | @Override 68 | public void onItemClick(AdapterView parent, View view, int position, long id) { 69 | Toast.makeText(GridActivity.this, parent.getAdapter().getItem(position).toString(), 70 | Toast.LENGTH_SHORT).show(); 71 | } 72 | }); 73 | 74 | @Override 75 | public void onBackPressed() { 76 | 77 | if (gridView.isEditMode()) { 78 | gridView.stopEditMode(); 79 | } else { 80 | super.onBackPressed(); 81 | //进行数据持久化操作 82 | } 83 | } 84 | > 细节注意： 85 | > 86 | >当前开源项目只实现了拖拽特效,拖拽完成退出应用之后并没有实现数据持久化功能,如需要进行数据的持久化,需要监听返回按钮在else方法实现数据持久化操作。 87 | 88 | 89 | 90 | 91 | ### 5. 复制如下代码到Adapter 92 | 93 | public class CheeseDynamicAdapter extends BaseDynamicGridAdapter { 94 | public CheeseDynamicAdapter(Context context, List items, int columnCount) { 95 | super(context, items, columnCount); 96 | } 97 | 98 | @Override 99 | public View getView(int position, View convertView, ViewGroup parent) { 100 | CheeseViewHolder holder; 101 | if (convertView == null) { 102 | convertView = LayoutInflater.from(getContext()).inflate(R.layout.item_grid, null); 103 | holder = new CheeseViewHolder(convertView); 104 | convertView.setTag(holder); 105 | } else { 106 | holder = (CheeseViewHolder) convertView.getTag(); 107 | } 108 | holder.build(getItem(position).toString()); 109 | return convertView; 110 | } 111 | 112 | private class CheeseViewHolder { 113 | private TextView titleText; 114 | private ImageView image; 115 | 116 | private CheeseViewHolder(View view) { 117 | titleText = (TextView) view.findViewById(R.id.item_title); 118 | image = (ImageView) view.findViewById(R.id.item_img); 119 | } 120 | 121 | void build(String title) { 122 | titleText.setText(title); 123 | image.setImageResource(R.mipmap.ic_launcher); 124 | } 125 | }} 126 | 127 | > 细节注意： 128 | > 129 | > 必须继承BaseDynamicGridAdapter。 130 | 131 | * 详细的使用方法在DEMO里面都演示啦,如果你觉得这个库还不错,请赏我一颗star吧~~~ 132 |
