本文整理了Java中android.support.v4.content.AsyncTaskLoader类的一些代码示例，展示了AsyncTaskLoader类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。AsyncTaskLoader类的具体详情如下：
包路径：android.support.v4.content.AsyncTaskLoader
类名称：AsyncTaskLoader

AsyncTaskLoader介绍

[英]Static library support version of the framework's android.content.AsyncTaskLoader. Used to write apps that run on platforms prior to Android 3.0. When running on Android 3.0 or above, this implementation is still used; it does not try to switch to the framework's implementation. See the framework SDK documentation for a class overview.
[中]静态库支持框架的android版本。所容纳之物异步任务加载器。用于编写在Android 3.0之前的平台上运行的应用程序。在Android 3.0或更高版本上运行时，仍然使用此实现；它不会尝试切换到框架的实现。有关类概述，请参见框架SDK文档。
