gridViewPager // 设置数据总数量 .setDataAllCount(titles.length) // 设置背景图片(此时设置的背景色无效，以背景图片为主) .setBackgroundImageLoader(new GridViewPager.BackgroundImageLoaderInterface() { @Override public void setBackgroundImg(ImageView bgImageView) { bgImageView.setImageResource(R.drawable.ic_launcher_background);

} }) .show(); ``` # 7、刷新数据 **设置新属性，刷新** ``` gridViewPager // 数据大小有变化时，得设置 .setDataAllCount(titles.length) // 动态改变其他属性 .setRowCount(3) .setColumnCount(3) // 再次show()，gridViewPager不为空时，走notifyDataSetChanged()刷新数据 .show(); ``` **刷新指定页码数据（每页行列数、数据总数不变，只有某个数据的值改变时使用）** ``` // 页码从0开始，例如下面是只刷新第二页数据 gridViewPager.notifyItemChanged(1) ``` ## 实现就是如此简单 **添加我个人微信号交流，记得添加时备注一下哦** ![在这里插入图片描述](https://img-blog.csdnimg.cn/20200629201307276.jpg?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI4Nzc5MDgz,size_16,color_FFFFFF,t_70) **本人公众号，也可关注一波，共同交流吧。** ![在这里插入图片描述](https://img-blog.csdnimg.cn/2019012509485178.jpg?x-oss-process=image/watermark,type_ZmFuZ3poZW5naGVpdGk,shadow_10,text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzI4Nzc5MDgz,size_16,color_FFFFFF,t_70) ================================================ FILE: README_1.x.md ================================================ # GridPager GridPager组件：ViewPager结合GridView，轻松实现类似美团首页分类多页展示。也可用于表情面板的展示。 链式调用，属性配置，几行代码轻松搞定。 ① 应用的首页经常需要用到这样的分类**多页展示**的效果，还有些消息输入框需要这样的**表情面板**。 ② 既然是常用的，作为懒惰的我，肯定不会每次都去写一遍。网上也找了很多类似的例子，但始终不是我想要的**简洁接入**使用的方式。要么就是加载图片有限制，要么就是样式限制的太死，还得改源码，我不喜欢，我得造一个轮子。。。必须封装一个简单好用的组件，做到几行代码就可实现效果才行。于是乎，**GridPager组件**就诞生了。 # GridPager组件效果 ![在这里插入图片描述](https://img-blog.csdnimg.cn/20190801185758323.gif) # 如何使用GridPager组件 # 1、在根目录 build.gradle 添加: ``` allprojects { repositories { ... maven { url 'https://jitpack.io' } } } ``` # 2、在app项目下的build.gradle中添加： ``` dependencies { implementation 'com.github.mtjsoft:GridPager:v1.3.2' } ``` # 3、在需要使用的布局xml中添加GridPager组件，根据需要设置相关属性 ``` ``` # 4、GridPager组件的版本及属性说明 V1.3.2 -------------------------- 新增方法 | 属性说明 | 备注 ------------- | ------------- | ------------- setGridPagersetBackgroundImage() | 支持设置背景图片，不再是单一的背景颜色了 | 2019-11-8 17:52:08 V1.3.1 -------------------------- 说明 | 备注 ------------- | ------------- 优化自动计算高度方法。不手动设置setViewPageHeight()固定高度时，默认自动计算，自适应高度。 | 2019-9-28 20:48:57 V1.2.2 -------------------------- 新增方法 | 属性说明 | 备注 ------------- | ------------- | ------------- setViewPageHeight(152) | 手动设置ViewPager为固定的高度，单位dp。 | 2019-9-27 17:47:31 V1.2.1 -------------------------- 新增属性 | 属性说明 | 备注 ------------- | ------------- | ------------- background_color | 设置组件背景颜色，默认白色 | 2019-9-23 22:20:05 V1.2.0 -------------------------- 新增属性 | 属性说明 | 备注 ------------- | ------------- | ------------- point_margin_page | 设置指示器与page的间距,默认是verticalSpacing的值 | 2019-9-11 13:20:45 point_margin_bottom | 设置指示器与底部的间距,默认是verticalSpacing的值 point_is_show | 是否展示指示器,默认true展示 V1.1.0 -------------------------- 1.1.0 属性 | 属性说明 | 备注 ------------- | ------------- | ------------- verticalSpacing | 设置item的纵向间距 默认10dp 单位dp | 2019-8-22 16:09:55 img_width | 设置图片宽度 默认50dp 单位dp img_height | 设置图片高度 默认50dp 单位dp text_color | 设置文字颜色 默认黑色 imgtext_margin | 设置文字与图片的间距 默认5dp 单位dp text_size | 设置文字大小 默认10sp 单位sp row_count | 设置每页行数 默认2 column_count | 设置每页列数 默认4 point_width | 设置指示器的item宽度 默认8dp 单位dp point_height | 设置指示器的item高度 默认8dp 单位dp point_margin | 设置指示器的item的间距 默认8dp 单位dp point_normal_color | 指示器item未选中的颜色 默认灰色 point_select_color | 指示器item选中的颜色 默认红色 point_is_circle | 指示器的item是否为圆形，默认圆形直径取宽高的最小值 # 5、代码实现。链式调用，只需要设置总数量即可。数据绑定完全自定义，不受任何图片加载框架限制，更加自由。 ``` GridPager gridPager = findViewById(R.id.gridpager);
