Android数据绑定：找不到属性app：list的setter

Question

This is my listView

<ListView
    android:id="@+id/productListView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:list="@{page.results}"/>

I get this error:

java.lang.RuntimeException: Found data binding errors. ****/ data binding error ****msg:Cannot find the setter for attribute 'app:list' with parameter type java.util.List on android.widget.ListView. loc:33:20 - 33:31 ****\\ data binding error ****

This is my BindingAdapter

@BindingAdapter({"bind:list"})
public static void bindList(Context context, ListView view, ObservableArrayList<Result> list) {
    ProductsAdapter arrayAdapter = new ProductsAdapter(context,list);
    view.setAdapter(arrayAdapter);
}

Can someone please help with this issue.

Answer 1

You should leave the bind namespace out. Only @BindingAdapter("list") should suffice.

Additionally you don't need the Context parameter should use List<Result> instead of ObservableArrayList<Result>

@BindingAdapter("list")
public static void bindList(ListView view, List<Result> list) {
    Context context = view.getContext();
    view.setAdapter(new ProductsAdapter(context, list));
}
