ClickableSpan이 순환 게재 활동을 유지하지 않습니다.

Question

문자열의 부분 문자열에 clickablespan을 설정하고 onClick에 대화 상자 단편을 표시합니다.

처음 텍스트를 클릭하면 dialogfragment가 정상적으로 표시됩니다. 대화 상자를 닫은 후 화면을 회전하고 텍스트를 다시 클릭하면 IllegalStateException: Activity has been destroyed이 표시됩니다.

디버깅 할 때 활동이 null임을 발견했습니다.

이 내 코드입니다 :

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); 
}

Answer 1

당신이 바로 버그가 있습니다. 자식 FragmentManager은 activity에서 분리 될 때 깨진 내부 상태로 끝납니다. 하지만 간단하게 전화하면 Fragment에 onDetach을 사용하여 문제를 해결할 수 있습니다.

@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); 
    } 
}
