ViewPager+GridView组合控件实现网格布局分页效果
- 可自由定制Item布局
- 无需写adapter适配器,直接调用setData()方法填充数据
- 只需实体类继承ItemModel即可
- 可显示本地图、网络图、资源ID图标,由开发者实现
- 动态计算PageGridView高度,不需要在布局里面写固定高度
- 可重复setData()方法刷新数据
属性名 | 说明 | 默认值 |
---|---|---|
pageSize | 每页大小 | 8 |
numColumns | 列数 | 4 |
isShowIndicator | 是否显示指示器 | true |
selectedIndicator | 选中指示点资源ID | R.drawable.shape_dot_selected |
unSelectedIndicator | 未选中指示点资源ID | R.drawable.shape_dot_normal |
indicatorGravity | 指示器位置 | center |
indicatorPaddingLeft | 指示器左内边距 | 0px |
indicatorPaddingRight | 指示器右内边距 | 0px |
indicatorPaddingTop | 指示器上内边距 | 0px |
indicatorPaddingBottom | 指示器下内边距 | 0px |
indicatorPadding | 指示器内边距 | 0px |
indicatorBackground | 指示器背景颜色 | Color.WHITE |
itemView | Item布局 | R.layout.item_view |
vpBackground | ViewPager 背景资源 | android.R.color.white |
vpPadding | ViewPager 内边距 | 0px |
- Item布局必须给定具体高度,默认itemView布局的高度为@dimen/item_height=80dp
- Item布局 TextView的id 为R.id.tv_item_name
- Item布局 ImageView的id 为R.id.iv_item_icon
- Item默认点击效果R.drawable.selector_item_view_bg
- Item点击颜色值:R.color.item_view_selected_color
- Item背景颜色值:R.color.item_view_normal_color
- 指示器点的的选中颜色为R.color.dot_selected_color
