Answer 1

Try This Work for sure...

  Step 1: Add this code in the build.gradle(Mobile:app)
           dataBinding {
                enabled = true
            }

        Example:
         buildTypes {
                release {
                    minifyEnabled false
                    proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
                }
            }

            **dataBinding {
                enabled = true
            }**
        }

        dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])
            implementation 'com.android.support:appcompat-v7:28.0.0'
            implementation 'com.android.support.constraint:constraint-layout:1.1.3'
            testImplementation 'junit:junit:4.12'
        .....
        }

        Step 2:
        Binding Can be done with Name of the .xml file as below example..
        Simply name of the xml file and prefix with binding...

        Example 1:
        if of your .xml file is activity_main.xml then Binding file should be MainActivityBinding
        Example 2:
        if of your .xml file is android_sunil.xml then Binding file should be AndroidSunilBinding

    Step 3: Sample Code:

    public class BaseObservableActivity extends AppCompatActivity {

            private ActivityBaseobservableBinding activityMainBinding;
        @Override
        protected void onCreate(@Nullable Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            activityMainBinding = DataBindingUtil.setContentView(this, R.layout.activity_baseobservable);

        }
    }

In the above code my .xml file name is activity_baseobservable so my binding class should be ActivityBaseobservableBinding activityMainBinding
