• Android Studio:3.1.0,3.1.1
• Gradle:4.4
• 构建工具:3.1.0

我正在使用DataBinding库.当我将布局文件添加到项目中或将任何视图添加到布局文件中时,Android Studio无法为布局生成Binding类,直到重建项目为止.

布局文件:

<?xml version="1.0" encoding="utf-8"?>
<layout 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"
    tools:context=".MainActivity">

    <data>

        <variable
            name="viewModel"
            type="com.qk365.thweeks.MainViewModel" />
    </data>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <android.support.design.widget.TabLayout
            android:id="@+id/main_tab"
            android:layout_width="match_parent"
            android:layout_height="50dp"
            android:layout_alignParentBottom="true"
            android:background="@android:color/white"
            android:elevation="5dp"
            app:tabGravity="fill"
            app:tabIndicatorHeight="0dp"
            app:tabMode="fixed"
            app:tabSelectedTextColor="#7343ea"
            app:tabTextAppearance="@style/TextAppearance.Design.Tab"
            app:tabTextColor="#181818" />

        <android.support.v4.view.ViewPager
            android:id="@+id/main_viewpager"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_above="@id/main_tab">

        </android.support.v4.view.ViewPager>

    </RelativeLayout>
</layout>

我检查了Android Studio日志,当布局文​​件发生变化时,总会有错误信息.
