GridView 组件的基本实现（本人也是个新手，哪里写的不对或者多余还请大家多多见谅）

private GridView gridView;private SimpleAdapter sim_adapter;private List<Map<String, Object>> data_list;private int[] imageview = {        R.drawable.chaoshi, R.drawable.quanqiugou, R.drawable.fuzhuangshichang,        R.drawable.shengxian, R.drawable.qiangbao, R.drawable.chongzhi,        R.drawable.jingdongdou, R.drawable.lingjuan, R.drawable.jinrong,        R.drawable.quanbu};private String[] imagename = {"京东超市", "全球购", "服装城", "京东生鲜", "1元抢宝",
        "充值中心", "领京豆", "领劵", "京东金融", "全部"};
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {    super.onViewCreated(view, savedInstanceState);    gridView = (GridView) view.findViewById(R.id.gridview);    //新建List    data_list = new ArrayList<Map<String, Object>>();    //获取数据    getData();    //新建适配器    String[] from = {"image", "text"};    int[] to = {R.id.image, R.id.text};    sim_adapter = new SimpleAdapter(getActivity(), data_list, R.layout.item, from, to);    //配置适配器    gridView.setAdapter(sim_adapter);    setListViewHeightBasedOnChildren(gridView);}
public List<Map<String, Object>> getData() {    //cion和iconName的长度是相同的，这里任选其一都可以    for (int i = 0; i < imageview.length; i++) {        Map<String, Object> map = new HashMap<String, Object>();        map.put("image", imageview[i]);        map.put("text", imagename[i]);        data_list.add(map);    }    return data_list;
计算CridView的高度
public static void setListViewHeightBasedOnChildren(GridView listView) {    // 获取listview的adapter    ListAdapter listAdapter = listView.getAdapter();    if (listAdapter == null) {        return;    }    // 固定列宽，有多少列    int col = 5;// listView.getNumColumns();    int totalHeight = 0;    // i每次加4，相当于listAdapter.getCount()小于等于4时 循环一次，计算一次item的高度，    // listAdapter.getCount()小于等于8时计算两次高度相加    for (int i = 0; i < listAdapter.getCount(); i += col) {        // 获取listview的每一个item        View listItem = listAdapter.getView(i, null, listView);        listItem.measure(0, 0);        // 获取item的高度和        totalHeight += listItem.getMeasuredHeight();    }    // 获取listview的布局参数    ViewGroup.LayoutParams params = listView.getLayoutParams();    // 设置高度    params.height = totalHeight;    // 设置margin    ((ViewGroup.MarginLayoutParams) params).setMargins(10, 10, 10, 10);    // 设置参数    listView.setLayoutParams(params);}
