在Android中预加载活动? [英] Preload activity in Android?

问题描述

我正在尝试制作一个与iPhone应用程序配对的Android应用程序-两者都将使用WebView来处理其90％的内容.在两个平台上创建新的WebView所花费的时间都不为零-对于iPhone，我在用户点击任何内容之前 创建WebView取得了一些成功，然后在他们点击时将其添加到导航堆栈中做.

I am attempting to make an Android app that will be paired with an iPhone app - both of which will use WebViews for 90% of their content. Creating a new WebView on both platforms takes a non-zero amount of time - for the iPhone I've had some success creating a WebView before the user taps anything, then adding it to the navigation stack when they do.

我正在尝试使用Android进行同样的操作，但是活动"的概念阻碍了我的发展.看来我的WebView必须是一个Activity的一部分，并且如果该Activity不是当前显示在屏幕上的那个View，则无法渲染视图.是这样吗如果是这样，是否没有能力预加载WebView并然后将其插入到Activity中?

I'm trying to do the same with Android but the 'Activity' concept is holding me back. It appears that my WebView has to be part of an Activity, and I cannot render the view without that Activity being the one currently shown on screen. Is this the case? If so, is there no ability to preload a WebView and then insert it into an Activity?

推荐答案

在运行后台任务方面，尝试着比活动"更着重于服务"概念. Webview可以在服务中运行，并且该服务可以在Create()上加载

Try looking at the Service concept more than Activity for running background tasks. Webview can be run in a service and that service can be loaded onCreate()
