先上一下可以实现的效果图
要实现的效果有几方面
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 , 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操作，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。
复制代码 代码如下:
public class ListItemCustom extends LinearLayout{

super(context);

custome_list_item.xml文件
复制代码 代码如下:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="40dp"
android:orientation="vertical"
android:id="@+id/test_dajej"
android:background="#ffffff">
<srit.collection.widget.costomtable.ListItemCustom android:id="@+id/custome_item"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
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。
