Use ListView to draw a custom table in Android (2)

The last time I wrote the "Use ListView to draw a custom table in Android," Many people leave a message code is incomplete and no data sample. But because of the project reasons, can not put all the source code. In the last two days, the time has been simplified and an example has been made.

Such as

First, the function:

1. Support Column Merging

2, consider the interface refresh optimization

3. Reserved part of the interface

4, support left and right scrolling

1. Enumeration class: Celltypeenum

Package Csdn.danielinbiti.custometableview.item;public enum Celltypeenum {  STRING   //character, DIGIT//   number  , label   //label}

This class defines the style supported by the table, expands it as needed, expands the new type, and also modifies how the new type style is created in Custometableitem

2. Core code Custometableitem, which corresponds to one row of the ListView item. Class supports column merging and does not implement row merging (row merge style control will be more complex, if you need to rewrite it yourself)

RowType: This value mainly represents a style that does not go in the table, and if the merged columns are the same row, it can be reused and no more is needed.
