我正在学习android数据绑定。我面临的问题是,在与当前设置的数据绑定相关的错误的情况下,我会收到非常笼统的错误消息,这些消息无法准确说明发生了什么事情和发生在哪里,而不是某些主题中提到的非常具体的消息关于数据绑定(for instance)。
考虑以下布局:
<?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">
<data>
<!--<import type="android.view.View"/>-->
<!--<import type="android.text.TextUtils"/>-->
<variable
name="movie"
type="us.kostenko.architecturecomponentstmdb.details.model.Movie" />
</data>
<TextView
<!-- ... -->
android:text="@{TextUtils.isEmpty(movie.release_date) ? @string/empty_date : movie.release_date}"/>
</layout>
请注意,导入被故意注释掉以触发错误。
我期望得到类似Identifiers must have user defined types from the XML file. TextUtils is missing it
的错误。但是我得到的错误是非常普遍的错误:
org.gradle.api.tasks.TaskExecutionException: Execution failed for task ':app:kaptDebugKotlin'.

我怀疑我的设置有问题。我正在使用Android Studio 3.1.4。
这是我的build.gradle
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android-extensions'
android {
//...
dataBinding { enabled = true }
}
dependencies {
// ...
kapt "com.android.databinding:compiler:3.1.4"
}
项目一级:
buildscript {
ext.kotlin_version = '1.2.70'
dependencies {
classpath 'com.android.tools.build:gradle:3.1.4'
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}
有什么主意我想念的是什么吗?
答案 0 :(得分:0)
这是我的,它工作正常,给出适当的错误,差异不大。试试这个...
