现在各种公司财务流程走到了手机端啊pad这一些产品上面，安卓画类似xls的库并不是太多（可能我见识少），看到一个Git上的库，觉得蛮好用的，尝试性的移植到了产品中去，写一下使用的心得
项目结构 
实现效果： 
Gradle:
compile 'de.codecrafters.tableview:tableview:0.9.5'最低Minimum SDK-Version: 11 最新版本 0.9.5
如何使用这样的一个tableview?
<de.codecrafters.tableview.TableView xmlns:table="http://schemas.android.com/apk/res-auto" android:id="@+id/tableView" android:layout_width="match_parent" android:layout_height="match_parent" table:columnCount="4" />table:columnCount是你表单的列数，当然需要引入xmlns:table=”http://schemas.android.com/apk/res-auto”
还有其他一些属性，在attributes.xml文件里定义
<resources> <declare-styleable name="TableView"> <attr name="columnCount" format="integer"/> <attr name="headerElevation" format="integer"/> <attr name="headerColor" format="color"/> </declare-styleable></resources>我拿Demo包的代码来作为解释的例子

每一列可实现的业务逻辑在此编写，但是你也可以不变写这部分，根据你的具体业务需要
public class CarComparators { public static Comparator<Car> getCarProducerComparator() { return new CarProducerComparator(); } public static Comparator<Car> getCarPowerComparator() { return new CarPowerComparator(); } public static Comparator<Car> getCarNameComparator() { return new CarNameComparator(); } public static Comparator<Car> getCarPriceComparator() { return new CarPriceComparator(); } private static class CarProducerComparator implements Comparator<Car> { @Override public int compare(Car car1, Car car2) { return car1.getProducer().getName().compareTo(car2.getProducer().getName()); } } private static class CarPowerComparator implements Comparator<Car> { @Override public int compare(Car car1, Car car2) { return car1.getPs() - car2.getPs(); } } private static class CarNameComparator implements Comparator<Car> { @Override public int compare(Car car1, Car car2) { return car1.getName().compareTo(car2.getName()); } } private static class CarPriceComparator implements Comparator<Car> { @Override public int compare(Car car1, Car car2) { if (car1.getPrice() < car2.getPrice()) return -1; if (car1.getPrice() > car2.getPrice()) return 1; return 0; } }}源码地址：http://yunpan.cn/cmZb5Z6UhR5KN 访问密码 ad37
