本文整理了Java中bolts.Task.continueWithTask()方法的一些代码示例，展示了Task.continueWithTask()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。Task.continueWithTask()方法的具体详情如下：
包路径：bolts.Task
类名称：Task
方法名：continueWithTask

Task.continueWithTask介绍

[英]Adds an asynchronous continuation to this task, returning a new task that completes after the task returned by the continuation has completed.
[中]将异步延续添加到此任务，返回一个新任务，该任务在延续返回的任务完成后完成。
