Question

我是数据绑定的新手，试图绑定recyclerview并收到以下错误。我正在关注github存储库。

android.databinding.tool.util.LoggedErrorException：找到数据绑定错误。数据绑定错误 msg：找不到用于的setter 参数类型的属性“ app：data” java.util.List上 android.support.v7.widget.RecyclerView。文件：D：\ Android \ All Demo \ TextAndImageSwitcher \ app \ src \ main \ res \ layout \ activity_list_data_binding.xml loc：17：24-17:45 \数据绑定错误

查看模型文件：

public class ListViewModel extends BaseObservable
{
    private Context context;
    public ListRecyclerAdapter listRecyclerAdapter;
    public List<User> userList;

    public ListViewModel(final Context context)
    {
        this.context = context;
        userList = new ArrayList<>();
        listRecyclerAdapter = new ListRecyclerAdapter(context, userList);
    }

    public void setUp()
    {
        populateData();
    }

    public void tearDown()
    {

    }

    @Bindable
    public List<User> getData()
    {
        return this.userList;
    }

    @Bindable
    public ListRecyclerAdapter getListRecyclerAdapter()
    {
        return this.listRecyclerAdapter;
    }

    private void populateData() {
        for (int i =0;i<=50;i++){
            userList.add(new User("Name("+i+")", "Mobile("+i+")", "Email("+i+")", "Address("+i+")"));
        }
        notifyPropertyChanged(BR.data);

    }
}

我的xml文件：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:app="http://schemas.android.com/apk/res-auto">
    <data>
        <variable
            name="listViewModel"
            type="com.example.admin.textandimageswitcher.ListViewModel"/>
    </data>
    <LinearLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".ListDataBindingActivity">
        <android.support.v7.widget.RecyclerView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:adapter="@{listViewModel.listRecyclerAdapter}"
            app:data="@{listViewModel.userList}"
            android:id="@+id/list_data_binding_recycler">
        </android.support.v7.widget.RecyclerView>
    </LinearLayout>
</layout>
