准备一个listview的xml，绑定到activity里面的listView的变量

准备一个继承自BaseAdapter的的MyAdapter，构造函数里面传入一个datasource的array，一个context，一般为绑定listview的activity（用来把item的xml实例化为layout）

准备一个数据模型，可以用hashmap，也可以用list

MainActivity.java

        parent, View view, int position, long id)            {                ObjectEntity data = dataSource.get(position);                                Toast.makeText(getApplicationContext(),                          data.desc,                         Toast.LENGTH_SHORT).show();             }        });    }        private void initGridView() {        setContentView(R.layout.ctivity_grid_main);        GridView gridView = (GridView)findViewById(R.id.gridView1);                dataSource = new ArrayList
