ClickableSpan 不保留旋转活动

【问题标题】：ClickableSpan is not retaining activity on rotationClickableSpan 不保留旋转活动
【发布时间】：2016-11-10 17:29:00
【问题描述】：

我在字符串的子字符串上设置clickablespan，并在onClick 中显示一个对话框片段。

当我第一次单击文本时，对话框片段正常显示。关闭对话框后，我旋转屏幕并再次单击文本，它会抛出IllegalStateException: Activity has been destroyed。

当我调试时，我发现活动为空。

这是我的代码：

String rawAuthor = String.format(getResources().getString(R.string.post_by), name, postDateStr); 

int i1 = rawAuthor.indexOf(" by "); 
int i2 = rawAuthor.indexOf(" on ");
postAuthorDate.setText(rawAuthor, TextView.BufferType.SPANNABLE);
postAuthorDate.setMovementMethod(LinkMovementMethod.getInstance());
postAuthorDate.setHighlightColor(ContextCompat.getColor(getActivity(), R.color.nav_bg)); 
Spannable spannable = (Spannable)postAuthorDate.getText(); 

ClickableSpan clickableSpan = new ClickableSpan() { 
   @Override public void onClick(View widget) { 
     Log.d(TAG, "I was clicked"); 
     //mOnTagCatClickedListener.OnTatCatClicked(name, authorId, "Author"); 
     TagCatFragment tagCatFragment = TagCatFragment.newInstance(name, authorId, "Author"); 

     try { 
       tagCatFragment.show(getChildFragmentManager(), "TagCAatFragment");  
     } catch (IllegalStateException e) { 
       e.printStackTrace(); 
     } 
   }
 }; 
 spannable.setSpan(clickableSpan, i1+4, i2, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE); 
 }

虽然我发现了this is a bug，请问有什么临时解决办法吗？

    【解决方案1】：

    你是对的，有错误。子 FragmentManager 在与 activity 分离时最终会出现内部状态损坏。但是很简单，您可以在Fragment 中使用onDetach 来修复它。

    @Override
public void onDetach() {
    super.onDetach();

    try {
        Field childFragmentManager = Fragment.class.getDeclaredField("mChildFragmentManager");
        childFragmentManager.setAccessible(true);
        childFragmentManager.set(this, null);

    } catch (NoSuchFieldException e) {
        throw new RuntimeException(e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException(e);
    }
}

    • 谢谢，我确实试过了，但没用。
    • @Ozuf 使用这个你得到任何其他错误或相同的错误。
    • 好像没试过一样。在发布这个问题之前，我已经尝试了很久。我知道这个答案最初是由 Marcus Forsell Stahre stackoverflow.com/a/15656428/6181476 给出的。但我认为解决方案不适用于ClickableSpan，因为它对我不起作用。
    • @Ozuf 你检查过这个吗？有很多解决方案有不同的问题code.google.com/p/android/issues/detail?id=42601
    • 先生，我也看过。这就是让 Marcus Forsell Stahre 在您的答案中提出临时修复的错误。
