Data binding

Android supports a mechanism for data binding so that data is bound with views and the glue code is minimized. Enable data binding by updating your build Gradle configuration as follows:

     android { 
       .... 
       dataBinding { 
        enabled = true 
       } 
     } 
     ... 
     dependencies { 
      ... 
      kapt 'com.android.databinding:compiler:2.3.1' 
    } 
    ...  

Now, you can define your binding expressions. Take a look at the following example:

    <?xml version="1.0" encoding="utf-8"?> 
    <layout xmlns:android="http://schemas.android.com/apk/res/android"> 
 
    <data> 
        <variable 
            name="note" 
            type="com.journaler.model.Note" /> 
    </data> 
 
    <LinearLayout 
        android:layout_width="match_parent&quot...
