问题 I am displaying all apps installed in a gridView. When loading a lot of apps, lets say 30 or more, the icons will display at the default Android icon and then several seconds later update to the correct icon.

Android GridView with Separator

由 风流意气都作罢 提交于 2019-12-13 11:34:59
问题 is possible to have a separator between elements of a GridView? Thanks 回答1: You'll probably have to play with padding and background colors. Set the background for the table to one color, and the background to each View in the table to another color. Set a 1 or 2 pixel padding around each View in the table, and you should have a border between. 回答2: from @FreewheelNat's comment, "In your xml for your GridView, use android:horizontalSpacing="1dp" and android:verticalSpacing="1dp" to set a 1

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 引言 上一篇文章中，我们主要讲解了如何在保证GridView控件的用户体验基础上，扩展GridView生成GridViewEx控件，增加动态添加新分组功能等，本文在上文的基础上，介绍如何在Windows10中使用GridViewEx，开发UWP应用。 Demo 下载： GridViewLiveTiles.zip GridViewEx.zip GridViewDemo.zip 开发UWP应用程序 开发UWP应用程序最好是从创建empty项目开始，重用已开发的一些模块，这样可以提高开发效率。 本文为了创建UWP 应用程序，首先创建一些通用类如下，详细代码见附件： Common/VisibilityConverter.cs Common/LayoutAwarePage.cs Common/SuspensionManager.cs DataModel 和Sample 文件夹下的所有文件都可以重用。 修改布局和导航 VisibilityConverter 和 SuspensionsManager暂时不需要修改，可直接在UWP中使用。主要修改布局和导航逻辑文件。 由于微软支持的设备种类越来越多，导致ApplicationViewState不再适用。UWP平台提供了其他的解决方法如 AdaptiveTriggers

GridView 动态添加数据

由 六眼飞鱼酱① 提交于 2019-12-13 10:20:35
【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 我有一个列表页，是采用GridView来实现的，初始数据是10个。当用户滑动到底部时，在去加载新的数据。 我在查看API时发现GridView有个addView方法，可以把一个子View添加到GridView里面去。但是该方法需要重写onDraw方法。网上收集了一些资料，整理下。 其实，动态的添加数据并不困难。首先，GridView在添加数据时，会使用到adapter，这个adapter继承自BaseAdapter. 在这个adapter的getView方法里面实现数据的加载。当有新数据时，只需要往原先的数据容器中添加数据，然后用adapter的notifyDataSetChanged方法，来告知adapter数据已经更新了，此时，adapter会自动往GridView里面添加数据。这样，网adapter里面动态添加数据的功能就实现了。 GridView实现分页，原理基本如上。但是要实现底部点击查看更多的按钮，则还需要一些改装。代码说明网上有很多，但是使用网上的demo有些问题。 添加一个“查看更多”按钮，采用的是在数据容器List中添加一个null值在最后，用来盛放footerview,这样，在GridView回滚的过程中，会出现空指针异常的错误。原因是在position小于List.size()-1的时候
