Java Android日历布局

我的日历布局如下所示：

A B C D E F G

A B C D E F G

A B C D E F G

A B C D

 blank A B C D

A B C D E F

A B C D E F

A B C D E F

我想让日历的第一天开始，例如，从第四个元素的位置开始（此实现应仅适用于日历的第一行），如下所示：

A B C D E F G

A B C D E F G

A B C D E F G

A B C D

 blank A B C D

A B C D E F

A B C D E F

A B C D E F

我有一个GridView，它使用一个RelativeLayout，里面有一个按钮，背景是另一个布局，现在应该不相关了

有什么建议吗。。。？谢谢：）
