无法解析Android数据绑定类

问题描述

使用数据绑定时，我无法按照数据绑定指南

While using data binding , I am not able to get class MainActivityBinding as per Data Binding Guide

我的布局名称是activity_main.xml.我还看到 Android-DataBinding-如何和何时会生成Binding类?但这对我没有帮助.

My layout name is activity_main.xml.I am also see Android - DataBinding - How and when the Binding classes will be generated? but it can't help me.

推荐答案

感谢大家的回答.我找到了使用ContentMainBinding类名称进行数据绑定的解决方案.让我解释一下.

Thanks to all for your answer.I found solution with ContentMainBinding class name for data binding.Lets me explain.

注意::将布局与 <include ... 一起使用时，这是具有数据绑定功能的<include layout="@layout/content_main"，与包含布局名称有关的类名称.这是ContentMainBinding

NOTE: While using layout with <include ... here is <include layout="@layout/content_main" having Data Binding functionality, the class name related to include layout name. Here is the ContentMainBinding

我的布局文件如下:

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:context="com.databindingdemo.app.MainActivity">
    ...
    <include layout="@layout/content_main" />
    ...
    </android.support.design.widget.CoordinatorLayout>

content_main.xml 是我在其中添加了数据绑定布局代码的布局.

And content_main.xml is layout where I added my Data Binding layout code.

因此可以使用 ContentMainBinding

So instead of using MainActivityBinding it can resolved with ContentMainBinding

对我有用的代码如下:

//Code for data binding
    ContentMainBinding contentMainBinding = DataBindingUtil.setContentView(this, R.layout.content_main);
    user = new User("Pranay", "Patel", "[email protected]", "9999999999");
    contentMainBinding.setUser(user);

完成.
