Mylinearlayoutmanager是我在线查找的自定义linearlayoutmanager,以解决SDK linearlayoutmanager的封装问题.

有什么办法可以在单个布局中有多个RecyclerVIEws？看来我每个布局不能附加多个LayoutManagers.

任何帮助将是非常欢迎:)

解决方法 我也有这个问题.我的活动使用Tabs,有三个片段,当我去第三个选项卡,并返回到第一个(或第二),这个错误被抛出.

搜索很多,我发现可能是垃圾收集器,因为我使用了强大的参考.

由于构造函数linearlayoutmanager使用活动作为参数(而不是片段),所以Tab键活动在选项卡更改期间保持活动状态.

从类中删除mlinearlayoutmanager中的本地字段,并使用弱引用,我可以摆脱这个问题：

之前：

public class MyFragment1 extends Fragment    private linearlayoutmanager linearlayoutmanager;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        linearlayoutmanager = new linearlayoutmanager(getActivity());        (...)    }    @OverrIDe    public VIEw onCreateVIEw(LayoutInflater inflater,Bundle savedInstanceState) {        (...)        mRecyclerVIEw.setLayoutManager(linearlayoutmanager);    }}

我改为：

public class MyFragment1 extends Fragment {    // private linearlayoutmanager linearlayoutmanager;    @OverrIDe    public voID onCreate(Bundle savedInstanceState) {        // linearlayoutmanager = new linearlayoutmanager(getActivity());        (...)    }    @OverrIDe    public VIEw onCreateVIEw(LayoutInflater inflater,Bundle savedInstanceState) {        (...)        mRecyclerVIEw.setLayoutManager(           new linearlayoutmanager(getActivity()));    }}
