如何在Gridview中显示网络数据

// 1. 获取网络数据
// 使用网络请求库发送网络请求，获取数据

// 2. 解析网络数据
// 使用解析库解析服务器返回的数据，转换为可操作的对象或数据结构

// 3. 创建适配器
public class MyAdapter extends BaseAdapter {
    private List<DataItem> mDataList;
    private Context mContext;

    public MyAdapter(Context context, List<DataItem> dataList) {
        mContext = context;
        mDataList = dataList;
    }

    @Override
    public int getCount() {
        return mDataList.size();
    }

    @Override
    public Object getItem(int position) {
        return mDataList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.grid_item_layout, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.textView = convertView.findViewById(R.id.text_view);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        // 4. 绑定数据
        DataItem item = mDataList.get(position);
        viewHolder.textView.setText(item.getTitle());

        return convertView;
    }

    private static class ViewHolder {
        TextView textView;
    }
}

// 5. 设置适配器
GridView gridView = findViewById(R.id.grid_view);
gridView.setAdapter(new MyAdapter(this, dataList));
