创建GridView的布局文件

自定义TextView用来显示GridView里的数据

然后是程序代码

public class CategoryActivity extends Activity {    private ArrayList
     
      
       > data;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.category_layout);                GridView categoryGrid = (GridView) findViewById(R.id.book_category_gridview_layout);        data = BookUtil.getCategory();        String[] from = new String[]{"name"};        int[] to = {R.id.text};        SimpleAdapter adapter = new SimpleAdapter(this, data, R.layout.category_grid_item, from, to);        categoryGrid.setAdapter(adapter);                categoryGrid.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(AdapterView
        arg0, View view, int postion,                    long id) {                Toast.makeText(CategoryActivity.this, data.get(postion).get("name"), Toast.LENGTH_SHORT).show();            }        });    }}
