android - RecyclerView : java. lang.IndexOutOfBoundsException : Inconsistency detected. 项目位置无效

Question

我已经开始在 Crashlytics 上收到此崩溃报告。我不知道如何重现它，但它似乎都是 RecyclerView 的内部代码。我认为这来 self 拥有的 RecyclerView，它从未真正改变过。用户可以刷新它，但随后会替换所有项目并调用 notifyDataSetChanged。

Answer 1

我一直面临这个问题，我很累地寻找解决方案。但是我找到了解决这个问题的答案，并且没有再次抛出异常。

public class MyLinearLayoutManager extends LinearLayoutManager  {
    public MyLinearLayoutManager(Context context) {
        super(context);
    }

    public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

    public MyLinearLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
        super(context, attrs, defStyleAttr, defStyleRes);
    }

    @Override
    public boolean supportsPredictiveItemAnimations() {
        return false;
    }

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        //override this method and implement code as below
        try {
            super.onLayoutChildren(recycler, state);
        } catch (Exception e) {
            e.printStackTrace();
        }
    } }

我希望这个答案能解决您的问题。
