RecyclerView：java.lang.IndexOutOfBoundsException：检测到不一致。无效的项目位置

Question

我已开始在 Crashlytics 上报告此崩溃。我不知道如何重现它，但它似乎都是RecyclerView 内部的代码。我认为这来自我从未真正改变过的RecyclerView。用户可以刷新它，但随后所有项目都会被替换并调用notifyDataSetChanged。

Answer 1

我一直面临这个问题，我很疲倦地寻找解决方案。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你的问题。

创建您自己的LinearLayoutManager。

CustomLinearLayoutManager.java

public class CustomLinearLayoutManager extends LinearLayoutManager {

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

    public CustomLinearLayoutManager(Context context) {
        super(context);
    }

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

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

如何在RecyclerView上设置CustomLinearLayoutManager。

CustomLinearLayoutManager customLinearLayoutManager= new HPLinearLayoutManager(mContext);
recyclerView.setLayoutManager(customLinearLayoutManager);

希望这会节省您的时间。
