ANDROID可以在xml数据绑定中声明内置数据类型

Question

有没有办法可以在xml数据绑定框架Android中声明内置数据类型？
例如像这样：

<data> 

<import type="android.text.Html"/> 

<variable 
    name="isDataFetched" 
    type="Boolean"/> 
    </data> 

感谢。

我使用这样的

<layout xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:app="http://schemas.android.com/apk/res-auto"> 
    <data> 
     <variable name="backgroundColor" 
        type="Integer"/> 
     <variable name="editTextColor" 
        type="Integer"/> 
    </data> 
<LinearLayout 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"

    app:backgroundResource="@{backgroundColor!=0?backgroundColor:android.R.color.black}"

和编程访问它在我的onCreate方法

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     getWindow().requestFeature(Window.FEATURE_ACTION_BAR); 

ActivityFormBinding binding= DataBindingUtil.setContentView(this,R.layout.activity_form); 
    binding.setEditTextColor(R.color.green); 
}
