当我的活动在三星 Galaxy Y 和 Ace Plus 上加载时 - mDPI/Ldpi 屏幕。列表视图文本和内容不加载。在触摸并尝试滚动内容时出现。

但它在我的开发手机三星 S2 上完美运行

经过一些测试，我发现这只发生在 2.X 版本的 Android 上。

请尝试将此属性添加到您的 xml 中的 ListView

android:cacheColorHint = "@android:color/transparent"

并删除黑色区域， android:fadingEdge="none"在您的ListView

嗨@Harsha，我尝试了一些基本功能的代码，并且在我的 Galaxy Y 上一切正常。可能是你的 color.xml 文件引起了一些问题。你可以下载这个测试项目，看看它是否有帮助。
