1、列不固定：可以根据数据源的不同生成不同的列数
2、表格内容可以根据数据源的定义合并列
3、要填写的单元格可以选择自定义键盘还是系统键盘
奔着这三点，做了个简单的实现，把源码贴一下（因为该点是主界面中的一部分，不便于放整个Demo）
自定义适配器，CallBackInterface是自定义的回调接口，这里定义回调是因为数据输入时需要及时保存
复制代码 代码如下:
public class SiteDetailVIEwAdapter extends BaseAdapter implements CallBackInterface{
private Context context;
private LayoutInflater inflater;
private ArrayList<HashMap<String,Object>> Lists;
private KeyBoard keyBoard = null;//自定义键盘
private ListVIEw ListVIEw = null;
private boolean isReadonly = false;//是否是浏览状态
private String[] arrCellType = null;
private int[] arrheadWIDth = null;//每列宽度
public SiteDetailVIEwAdapter(Context context,ArrayList<HashMap<String,Object>> Lists
,KeyBoard keyBoard,ListVIEw ListVIEw,boolean isReadonly
,int[] arrheadWIDth) {
super();
this.context = context;
this.Lists = Lists;
inflater = LayoutInflater.from(context);
this.keyBoard = keyBoard;
this.ListVIEw = ListVIEw;
this.isReadonly = isReadonly;
this.arrheadWIDth = arrheadWIDth;
this.ListVIEw.setAdapter(this);
}
@OverrIDe
public int getCount() {
// Todo auto-generated method stub
return Lists.size();
}
@OverrIDe
public Object getItem(int arg0) {
// Todo auto-generated method stub
return arg0;
}
@OverrIDe
public long getItemID(int arg0) {
// Todo auto-generated method stub
return arg0;
}
@OverrIDe
public VIEw getVIEw(int index,VIEw vIEw,VIEwGroup arg2) {
HashMap map = Lists.get(index);
String type = (String)map.get("rowtype");
ArrayList<ItemCell> itemCells = new ArrayList();
//String cellValue,String cellKey,long cellType,int cellinRow,int cellSpan
ItemCell itemCellXuHao = new ItemCell((index+1)+"","-1",1,-1,1);
itemCells.add(itemCellXuHao);
for(int i=0;i<map.size()-1;i++){
ItemCell itemCell = (ItemCell)map.get(i+"");
itemCells.add(itemCell);
}
//性能优化后需要放开注释danIElinbiti
if(vIEw == null||vIEw!=null&&!((ListItemCustom)vIEw.getTag()).getType().equals(type)){
vIEw = inflater.inflate(R.layout.customel_List_item,null);
ListItemCustom itemCustom = (ListItemCustom)vIEw.findVIEwByID(R.ID.custome_item);
itemCustom.buildItem(type,context,isReadonly,arrheadWIDth,itemCells,index
,this.ListVIEw,this.keyBoard,this);
vIEw.setTag(itemCustom);
}else{
ListItemCustom itemCustom = (ListItemCustom)vIEw.getTag();
itemCustom.refreshData(itemCells,index);
}
if(index%2 == 0){
vIEw.setBackgroundcolor(color.argb(250,255,255 ));
}else{
vIEw.setBackgroundcolor(color.argb(250,224,243,250 ));
}
return vIEw;
}
@OverrIDe
public boolean exectueMethod(Object params) {
String[] arr = (String[])params;
HashMap map = Lists.get(Integer.parseInt(arr[0]));
ItemCell itemCell = (ItemCell)map.get(arr[1]);
itemCell.setCellValue(arr[2]);
itemCell.setIsChange(true);
return false;
}
ListVIEw每行的布局，内部代码是有冗余的，因为是Demo，所以先以效果未准，未进行代码重构，注意不能往ListItemCustom中传入每行的Map来进行值得获取或者输入更新等 *** 作，因为Map是按地址方式，再结合ListVIEw的绘制方式，最终的map不是你想象的map。

以上是核心的文件内容。有了列合并，行合并也不远了。可以在自定义的布局中多加个linearLayout来实现行合并。 总结
