java.lang.IllegalStateException：RecyclerView没有的LayoutManager [英] java.lang.IllegalStateException: RecyclerView has no LayoutManager

问题描述

我得到下面的异常 -

I am getting below exception-

Caused by: java.lang.IllegalStateException: RecyclerView has no LayoutManager
            at android.support.v7.widget.RecyclerView.generateLayoutParams(RecyclerView.java:2820)
            at android.view.LayoutInflater.rInflate(LayoutInflater.java:757)
            at android.view.LayoutInflater.inflate(LayoutInflater.java:492)
            at android.view.LayoutInflater.inflate(LayoutInflater.java:397)
            at com.peoplecloud.app.guggu.NavigationDrawerFragment.onCreateView(NavigationDrawerFragment.java:75)
            at android.app.Fragment.performCreateView(Fragment.java:1700)
            at android.app.FragmentManagerImpl.moveToState(FragmentManager.java:866)
            at android.app.FragmentManagerImpl.moveToState(FragmentManager.java:1040)
            at android.app.FragmentManagerImpl.addFragment(FragmentManager.java:1142)
            at android.app.Activity.onCreateView(Activity.java:4803)

我添加了以下code，但我仍然得到这个例外 -

I have added the following code,however i am still getting this exception-

 LinearLayoutManager layoutManager = new LinearLayoutManager(getActivity());
    layoutManager.setOrientation(LinearLayoutManager.VERTICAL);
    mDrawerList.setLayoutManager(layoutManager);

如果我删除回收站视图里面的内容则没有例外。

If I remove the content inside recycler view then there is no exception.

推荐答案

卸下 RecyclerView 在布局文件中的子元素。我不知道这些都应该是，但他们不应该成为孩子的 RecyclerView 。

Remove the child elements from RecyclerView in your layout file. I don't know what those are supposed to be, but they are not supposed to be children of the RecyclerView.
