android控件之GridView

GirdView

 用于在界面上按照行列方式来显示多个组件

     常用的三个属性（基本属性除外）：

• ndroid：numColums   每一行显示几列
• android：horizontalSpacing 两列之间的距离
• android：verticalSpacing   两行之间的距离

example ：

使用simpleAdapter 和 OnItemClickListenner 来实现

部分代码如下：

-----------------------------------------------------------------------------------------

  /*
   * 1.准备数据源
   * 2.新建适配器（simpleAdapter）
   * 3.GridView加载适配器
   * 4.GridView配置事件监听器（onItemClickListenner）
   *   
   */

private GridView gv;
 private List <Map<String,Object>> data;
 private int []icon={R.drawable.icon1,R.drawable.icon2,R.drawable.icon3,
      R.drawable.icon4,R.drawable.icon5,R.drawable.icon6,
      R.drawable.icon7,R.drawable.icon8,R.drawable.icon9,};
 private String[]name={"啊","哦","额","嗯","噶","吖","噢","喔","阿"};
 private SimpleAdapter sim_adapter;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  gv = (GridView) findViewById(R.id.gridView);
  data = new ArrayList<Map<String,Object>>();
  sim_adapter = new SimpleAdapter(this, getdata(), R.layout.item, new String[]{"image","text"}, new int[]{R.id.imageView,R.id.textview});
  gv.setAdapter(sim_adapter);
  }

 private List<Map<String,Object>> getdata() {
  // TODO Auto-generated method stub
  
  for(int i=0;i<9;i++){
   Map<String,Object>map = new HashMap<String, Object>();
   map.put("image", icon[i]);
   map.put("text", name[i]);
   data.add(map);
  }
  return data;
 }

至于实现 OnItemclickListenner 是和之前的Listview 基本是一样的原理

这两个组件相似度很高..
