我正在设置clickablespan字符串的子字符串并在 onClick.

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); 
 }

你是对的，有错误。当孩子FragmentManager与activity. 但是很简单，您可以onDetach在Fragment.

@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);
    }
}
