java - Android java.lang.IllegalArgumentException : Duplicate key in ArrayMap: null

Question

我收到此错误

Caused by java.lang.IllegalArgumentException: Duplicate key in ArrayMap: null

不在我当前的设备中，但它来自 crashlytics，但我无法在我自己的设备中重新生成此问题尝试了所有可能的方法，但无法在我的设备中出现同样的错误，下面是我的代码，非常感谢答案。

//the below method is causing IllegalArgumentException

                }
            }
        }

下面是我从适配器开始这个 fragment 的代码

private void setonClickListeners(ResourceQuestionsViewHolder viewHolder, final int position) {
        viewHolder.mContainerView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {

                DialogFragment questionSwipeFragment = QuestionSwipeFragment.newInstance(getExtractResourceInfo(position).getExtractedList(), getExtractResourceInfo(position).getPosition(), Constants.QB_DETAILS_FRAGMENT, isFavourited, isPaginationRequest, chapterId, sectionId, resourcePageNo, markId, difficulties, mCurrentPage, mTotalPage);
                questionSwipeFragment.show(((QuestionBankActivity) mContext).getSupportFragmentManager(), "dialog");

            }
        });
}

private void setonLongClickListener(SubSectionResourceQuestionsViewHolder viewHolder, final int position) {
        viewHolder.mContainerView.setOnLongClickListener(new View.OnLongClickListener() {
            @Override
            public boolean onLongClick(View v) {

                DialogFragment questionBankFragment = QBSubSectionDetailFragment.newInstance(mResourceList, false, position);
                questionBankFragment.show(((SynopsisActivity) mContext).getSupportFragmentManager(), "dialog");

                return true;
            }
        });
    }

Answer 1

当我遇到这个问题时，它实际上是由其他异常引起的
我的问题是由启动未导出的 Activity 引起的
解决方案:

检查您传递的参数是否有多个 空 key

检查是否启动了未设置导出的Activity(用于启动其他应用)

您可以直接设置对 fragment 的引用，而无需通过 传递它们。 bundle
