片段onHiddenChanged不叫 [英] Fragment onHiddenChanged not called

问题描述

我最近添加片段我的应用程序。对于新的应用程序，我需要得到
一旦示出我的片段通知。所以，我可以马上做一些计算作为我的
片段再次显示。

我的片段使用具有TabIndicator和它的其中仅使用一个FragmentClass
几次。

下面是正常标准覆盖类：

  @覆盖
公共无效onHiddenChanged（布尔隐藏）{
    super.onHiddenChanged（隐藏）;
}
 

解决方案

仍在寻找答案？ onHiddenChanged不会被调用的第一次显示一个片段。只有当它改变状态。

从文档：

  

片段时，隐藏的状态（如是否隐藏（）返回）已经改变调用。片段开始时没有隐藏;这将被称为每当片段从改变状态。

I recently added Fragments to my applications. For a new application i'll need to get notified as soon as my fragment is shown. So i can do some calculations as soon as my fragment is shown again.

My Fragment is used with a TabIndicator and it's only one FragmentClass which is used a few times.

Here's the normal standard override class:

@Override
public void onHiddenChanged(boolean hidden) {
    super.onHiddenChanged(hidden);
}

解决方案

Still looking for an answer? onHiddenChanged doesn't get called the first time an fragment is shown. Only when it changes state.

From the documentation:

Called when the hidden state (as returned by isHidden()) of the fragment has changed. Fragments start out not hidden; this will be called whenever the fragment changes state from that.
