Android RecyclerView+CheckBox 滾動後選擇錯亂問題解決

1、CheckBox的設置

holder.mBinding.cb.setOnCheckedChangeListener(null);
    holder.mBinding.cb.setChecked(mCheckStates.get(position, false));

    holder.mBinding.cb.setOnCheckedChangeListener((buttonView, isChecked) -> {
      if (isChecked) {
        mCheckStates.put(position, true);
      } else {
        mCheckStates.delete(position);
      }
      if (mOnScenicCheckedListener != null) {
        mOnScenicCheckedListener.onChecked(mCheckStates);
      }
    });

先清除監聽器，再設置監聽狀態，再重新設置監聽

2、使用集合來保存checkbox的狀態

  private SparseBooleanArray mCheckStates = new SparseBooleanArray();

    holder.mBinding.cb.setOnCheckedChangeListener((buttonView, isChecked) -> {
      if (isChecked) {
        mCheckStates.put(position, true);
      } else {
        mCheckStates.delete(position);
      }
      if (mOnScenicCheckedListener != null) {
        mOnScenicCheckedListener.onChecked(mCheckStates);
      }
    });
