Use include in databinding

DataBinding Next Use include Include transfer of objects , Event monitoring .
include The layout is as follows ：
custom_home.xml

<layout  
	xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:binding="http://schemas.android.com/apk/res-auto">
    <data>
        <variable
            name="user"
            type="com.yc.bean.User" />
        <variable
            name="onImgClick "
            type="android.view.View.OnClickListener" />

    </data>
     <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:orientation="horizontal">
             <ImageView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:onClick ="@{onImgClick }"
                    android:src="@mipmap/ic_home_position"
                     />

                <TextView
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:text="@{user.name}"
                    android:textColor="@color/colorBarText"
                    android:textSize="12sp" />
      </LinearLayout>
 </Layout>
            

Here we use objects and monitor Words , You have to declare the corresponding variable

main.xml In the code ：

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:binding="http://schemas.android.com/apk/res-auto">
    <data>
        <import type="com.yc.ui.home.HomeFragmentViewModel"/>
        <variable
            name="viewModel"
            type="HomeFragmentViewModel" />
        <variable
            name="user"
            type="com.yc.bean.User"/>
    </data>
    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
        .......
          <include android:id="@+id/include"
            layout="@layout/custom_home"
            binding:onImgClick ="@{viewModel.onImgClick}"
            binding:user="@{user}"/>

    </FrameLayout>

</layout>
        
    

binding:user=@{user}

here binding:include Middle variable name =@{ The listening or entity object passed in }
The name must correspond, or you can't find The class name must also be the same .

viewModel Medium method ：

 public View.OnClickListener onImgClick = new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            ToastUtils.showShort(" Click on the avatar ");
        }
    };
