Android中使用ListView绘制自定义表格(3)
把自定义表格又改进了一下，可以支持行合并。表格分为简单和复杂两种模式
1、简单模式就是《Android中使用ListView绘制自定义表格(2)》描述的方式。不支持行合并
2、复杂模式支持行列合并
1、基于上回上传的代码，改动文件如下
package csdn.danielinbiti.custometableview.item;
public class ItemCell {
private String cellValue = http://www.mamicode.com/"";//单元格的值>
CustomeTableItem.java

}

}

2、简单模式和复杂模式可以通过布局文件配置。不进行设置默认是简单模式<?xml version="1.0" encoding="utf-8"?>
<csdn.danielinbiti.custometableview.item.CustomeTableItem android:id="@+id/custome_item"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:tag="1"
android:gravity="center_vertical"
/>
android:tag="2"为复杂模式，不进行配置为简单模式3、测试数据格式
private void testAddContentRows(HashMap contentMap){
HashMap rowMap1 = new HashMap();
lists.add(rowMap1);
this.testAddRows(rowMap1, 1, "r1-1-1(1)", CellTypeEnum.LABEL,0,0,1);
this.testAddRows(rowMap1, 1, "r1-2-1(1)", CellTypeEnum.LABEL,1,0,1);
this.testAddRows(rowMap1, 1, "r1-1-2(1)", CellTypeEnum.STRING,0,1,2);
this.testAddRows(rowMap1, 2, "r1-1-3(2)", CellTypeEnum.STRING,0,2,2);
this.testAddRows(rowMap1, 1, "r1-1-4(1)", CellTypeEnum.DIGIT,0,4,2);//注意这个列号的标识，必须是前面列号+跨行数
rowMap1.put("rowtype", "css1");//表样标示放在内容添加后再添加
HashMap rowMap2 = new HashMap();
lists.add(rowMap2);
this.testAddRows(rowMap2, 1, "r2-1-1(1)", CellTypeEnum.LABEL,0,0,1);
this.testAddRows(rowMap2, 1, "r2-2-1(1)", CellTypeEnum.LABEL,1,0,1);
this.testAddRows(rowMap2, 1, "r2-1-2(2)", CellTypeEnum.STRING,0,1,2);

this.testAddRows(rowMap2, 2, "r2-2-3(1)", CellTypeEnum.STRING,1,2,1);
this.testAddRows(rowMap2, 1, "r2-1-4(1)", CellTypeEnum.DIGIT,0,4,2);
rowMap2.put("rowtype", "css2");//表样标示放在内容添加后再添加

this.testAddRows(rowMap3, 1, "r3-1-4(1)", CellTypeEnum.DIGIT,0,4,3);
rowMap3.put("rowtype", "css3");//表样标示放在内容添加后再添加
HashMap rowMap4 = new HashMap();
lists.add(rowMap4);
this.testAddRows(rowMap4, 1, "r4-1-1(1)", CellTypeEnum.LABEL,0,0,1);
this.testAddRows(rowMap4, 1, "r4-2-1(1)", CellTypeEnum.LABEL,1,0,1);

this.testAddRows(rowMap4, 1, "r4-1-4(1)", CellTypeEnum.DIGIT,0,4,3);
rowMap4.put("rowtype", "css3");//表样标示放在内容添加后再添加
}
private void testAddRows(HashMap rowMap,int colSpan,String cellValue,CellTypeEnum cellType,int rowNum,int colNum,int rowSpan){
ItemCell itemCell = new ItemCell(cellValue,cellType,colSpan);
itemCell.setPos(rowNum, colNum, rowSpan);
rowMap.put(rowMap.size()+"", itemCell);
} //this.testAddContent(contentMap);//简单模式,原来的代码，改行替换成下面代码就可以
this.testAddContentRows(contentMap);//复杂模式
基于listview方式的动态布局已经实现了行列合并模式，基本也就告一段落了，希望能够给后面的人提供帮助。至于一些样式的设置，这里没有具体提供，包括数字输入时的数字键盘，输入改变时数据获取等方式都没有提供，这些只能使用的人自己根据需要进行加减了。建议对于最好弄个简单的html之类的布局设计器，这样生成能够使用的数据相对比较好点，要不人工计算数据很容易出错。
源码参见自定义表格(2) ，改动的代码已经在上面都贴出来了。
