爲什麼不重寫PendingTransition工作？

我使用此功能在2個活動之間切換時創建動畫。但它使我的應用程序停止（不會崩潰，就像暫停）。我從活動的片段中的適配器調用overridePendingTransition。爲什麼不重寫PendingTransition工作？

公共類LessonAdapter擴展RecyclerView.Adapter {

私有列表lessonList;

private Context mContext;

public LessonAdapter(Context context, List<Lesson> ll) { 
    lessonList = ll; 
    mContext = context; 

@Override 
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.lesson_card,parent, false); 
    return new LessonHolder(view); 
} 

@Override 
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) { 
    final LessonHolder lessonHolder = (LessonHolder) holder; 
    lessonHolder.lessonName.setText(lessonList.get(position).getLessonName()); 
    lessonHolder.lessonName.setTextColor(Color.parseColor("#0B8E46")); 
    lessonHolder.lessonDescription.setText(lessonList.get(position).getLessonDescription()); 
    lessonHolder.lessonDescription.setTextColor(Color.parseColor("#686868")); 

    if (lessonList.get(position).getUuid() == 1) { 
     lessonHolder.lessonCard.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent i = new Intent(mContext, WordTypeLessonActivity.class); 
       mContext.startActivity(i); 
       ((Activity) mContext).overridePendingTransition(R.anim.slide_in, R.anim.slide_out); 
      } 
     }); 
    } 
    if (lessonList.get(position).getUuid() == 2) { 
     lessonHolder.lessonCard.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent i = new Intent(mContext, TenseLessonActivity.class); 
       mContext.startActivity(i); 
       ((Activity) mContext).overridePendingTransition(R.anim.slide_in, R.anim.slide_out); 
      } 
     }); 
    } 
    if (lessonList.get(position).getUuid() > 2) { 
     lessonHolder.lessonCard.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Intent i = new Intent(mContext, LessonActivity.class); 
       i.putExtra("lesson_id", lessonList.get(position).getUuid()); 
       mContext.startActivity(i); 
       ((Activity) mContext).overridePendingTransition(R.anim.slide_in, R.anim.slide_out); 
      } 
     }); 
    } 
} 

@Override 
public int getItemCount() { 
    return lessonList.size(); 
}

}

一切似乎都很好，你如何通過像這樣的LessonAdapter（getActivity，列表）對嗎？ –

我有一個外面的課程列表，在片段中，我調用了getContext（）。像這樣「LessonAdapter（getContext（），list）」 –

嘗試像這樣調用意圖Intent i = new Intent（getContext（），TenseLessonActivity.class）; –
