检测到不一致无效视图支架适配器错误

Question

我为我的学校项目制作了一个与 Firestore 一起运行的应用程序。当我添加第一个查询时没有问题，但如果我想添加第二个查询并返回到MainActivity，我会收到此错误并且应用程序终止。

Answer 1

我解决了我的问题。问题发生在MainActivity，它是由RecyclerView在不同线程中修改的数据引起的。检查所有数据访问和包装LinearLayoutManager将被视为解决方案。

我在第一个答案中编写了@sakiM给出的代码：RecyclerView和java.lang.IndexOutOfBoundsException：检测到不一致。三星设备中的视图固定器适配器positionViewHolder无效 这是代码：

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

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

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

    @Override
    public void onLayoutChildren(RecyclerView.Recycler recycler, RecyclerView.State state) {
        try {
            super.onLayoutChildren(recycler, state);
        } catch (IndexOutOfBoundsException e) {
            Log.e("TAG", "meet a IOOBE in RecyclerView");
        }
    }
}

• 然后我将我的匹配RecyclerView到WrapContentLinearLayoutManager

这是代码：

RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recycler_view); recyclerView.setLayoutManager(new WrapContentLinearLayoutManager(this,LinearLayoutManager.VERTICAL,false));

谢谢大家，祝你有美好的一天
