在include中使用

首先写出layout布局：include_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">

    <data>

        <import type="com.lkdot.tbind.DataBean" />

        <variable
            name="data"
            type="DataBean" />

    </data>

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:gravity="center"
            android:text="@{data.name}" />

    </android.support.constraint.ConstraintLayout>
</layout>

---

再修改：activity_main.xml
加入xmlns:bind=“http://schemas.android.com/apk/res-auto”

主要语句：bind:data="@{data}"

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bind="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools">

    <data>

        <import type="com.lkdot.tbind.DataBean" />

        <variable
            name="data"
            type="DataBean" />

    </data>

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FFFFFF"
        tools:context=".MainActivity">

        <include
            layout="@layout/include_layout"
            bind:data="@{data}" />
            
    </android.support.constraint.ConstraintLayout>
</layout>

再看MainActivity.java
这里没有变

package com.lkdot.tbind;

import android.databinding.DataBindingUtil;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.lkdot.tbind.databinding.ActivityMainBinding;

public class MainActivity extends AppCompatActivity {

    ActivityMainBinding activityMainBinding;
    DataBean textData;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        activityMainBinding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        textData = new DataBean("Start", "NorthernBrain", 25, true);
        activityMainBinding.setData(textData);
    }
}
