<declare-styleable name="ZoomHoverView">
<!--每行多少列-->
<attr name="zhv_column_num" format="integer" />
<!--分割线-->
<attr name="zhv_divider" format="dimension" />
<!--距离父控件的margin-->
<attr name="zhv_margin_parent" format="dimension" />
<!--动画持续时间-->
<attr name="zhv_zoom_duration" format="integer" />
<!--动画缩放的倍数-->
<attr name="zhv_zoom_to" format="float" />
<!--是否使用基础的宽高(ZoomHoverGridView使用)-->
<attr name="zhv_use_baseWH" format="boolean" />
<!--设置基础的宽(ZoomHoverGridView使用)-->
<attr name="zhv_base_width" format="dimension" />
<!--设置基础的高(ZoomHoverGridView使用)-->
<attr name="zhv_base_height" format="dimension" />
</declare-styleable>- 新增ZoomHoverGridView继承自GridLayout，可以实现拉伸行和列
- 修改添加拉伸的方法，放进了view中（原来在adapter中）
