Android CustomView 中的数据绑定 <merge> 无法解析资源

Question

尝试在 CustomView(Group) 中使用 DataBinding

布局如下所示：

<layout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools">

<merge
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <CheckBox
        android:id="@+id/customview_checkbox1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:tag="@string/checkbox_value_key"
        android:text="My CheckBox"/>
    ....
</merge>
</layout>

CustomView（扩展 FrameLayout）inflation:

view = DataBindingUtil.inflate((LayoutInflater) getContext().getSystemService(Context
            .LAYOUT_INFLATER_SERVICE), R.layout.custom_view, this, true);

导致此错误：

Error:(46, 61) error: cannot find symbol method getResources()

生成的绑定Class：

public ViewBodyPartsBinding(android.databinding.DataBindingComponent bindingComponent, View[] root) {
    super(bindingComponent, root[0], 0);
    final Object[] bindings = mapBindings(bindingComponent, root, 9, sIncludes, sViewsWithIds);
    this.mboundView0 = (android.widget.ImageView) bindings[0];
    this.mboundView0.setTag(null);
    this.mboundView2 = (android.support.percent.PercentRelativeLayout) bindings[2];
    this.mboundView2.setTag(null);
    ....
    this.customviewCheckbox1 = (android.widget.CheckBox) bindings[1];
    this.customviewCheckbox1.setTag(root.getResources().getString(<package>.R.string.checkbox_value_key));
    ....
    setRootTag(root);
    // listeners
    invalidateAll();
}

错误根据 George Mount 的说法。等待 Android Studio 2.3 修复该问题
