布局花费太多的时间来加载android

我的布局花费了太多的时间来加载大约2-3秒在实际device.My布局有很多观点从40-60意见。我正在检查各种条件以及在OnCreate().So任何人都可以建议我如何加载我的活动更快。而大部分的意见都有背景图片。实际上我的整个布局是充满了ImageView。 下面的onCreate()布局花费太多的时间来加载android

你需要看看时间在哪里。我只是放了一些日志打印，因为他们得到时间戳。 – Ifor

@我为什么把日志打印出来？ – sankettt

尝试使用线程或者如果它不可能，请观察如果在您的方法中，OnCreate，是否存在对布局完成呈现之前占用资源的某些东西的调用。

是的，我确实有调用共享偏好，我加载动画，并伴随它几个sounds.doing一些日期相关的计算和数据库编码 – sankettt

让onCreateComplete尽可能快。不要拿着它来加载你的意见。 启动AsyncTasks以加载findViewById中的视图。 然后在asyntasks onPostsExecute中，您可以为您的视图设置值，例如将图像设置为图像浏览等。

值得一试。

我一定会试一试。你能告诉我哪些代码应该放在asynctask中吗？ – sankettt

可以帮助我在这方面的例子。我对这个东西相当陌生，尽管我阅读大量的东西是为了显示从互联网加载文件或与之相关的文件的进度。并随着加载的图像我有数据库和阅读的共享偏好以及。任何有关这方面的帮助将非常感激，并会对我很好 – sankettt
