static and dynamic text display.txt

UseCase: If we want to show in a textview "Model : BMW" 
model - static data 
BMW - dynamic data, If your doing a n/w call and in your model you have a model attribute for vehcile object, below is one of approach.
-------
define this in your strings.xml 

<string name="display_model">Model %s</string>

* In case you have a data object vehicle as a livedata  then you do something like this in your Viewmodel
* displayModel is a variable that will be used by data binding to show in your layout

val displayModel = Transformations.map(vehicle) {
       app.applicationContext.getString(when(it.isCarLuxury){
            true -> R.string.display_luxury
            false -> R.string.display_normal
        }, it.model)
    }
    
* In your layout you define your databinding variable and in your textview call like this 

<data>
        <variable
            name="detailViewModel"
            type="com.android.vechile.detail.DetailViewModel" />
    </data>
<TextView
                android:id="@+id/moel_value_text"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@{detailViewModel.displayModel}"
