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..
