【问题描述】:
我猜由于 gradle 中的某些问题,我无法添加 notifyPropertyChanged(int itemId)!
任何帮助将不胜感激
public class RegisterForm extends BaseObservable {
@Bindable
public String firstName;
@Bindable
public int getFirstNameLabelVisibility(){
return TextUtils.isEmpty(firstName) ? View.INVISIBLE : View.VISIBLE;
}
public void setFirstNameFromView(String firstNameFromView) {
firstName = firstNameFromView;
// notifyPropertyChanged(BR.firstName); this line is giving error!
}
}
Build.gradle // 用于应用程序
apply plugin: 'com.android.application'
apply plugin: 'com.android.databinding'
apply plugin: 'android-apt'
android {
compileSdkVersion 23
buildToolsVersion "23.0.2"
defaultConfig {
applicationId "com.example.jivrajsingh.databindingimp"
minSdkVersion 15
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_7
targetCompatibility JavaVersion.VERSION_1_7
}
}
configurations {
apt
}
dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
apt 'com.android.databinding:compiler:1.0-rc0'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.squareup.okhttp:okhttp:2.4.0'
compile 'com.google.android.gms:play-services-auth:8.3.0'
compile 'com.google.android.gms:play-services-gcm:8.3.0'
}
Build.gradle // 用于项目
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
// classpath 'com.android.tools.build:gradle:1.3.0'
classpath 'com.android.databinding:dataBinder:1.0-rc2'
classpath 'com.neenbedankt.gradle.plugins:android-apt:1.+'
}
}
allprojects {
repositories {
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
感谢您宝贵的时间:)
【问题讨论】:
-
为什么两者都有?
classpath 'com.android.tools.build:gradle:2.0.0-alpha1'和classpath 'com.android.tools.build:gradle:1.3.0'还在哪里启用 App 的 gradle 中的 dataBinding? ...您是否阅读了“数据绑定指南”? -
那是注释代码 (gradle:1.3.0).. 早些时候我有它然后我把它改成 2.0
-
我也在这里编辑...还有什么吗??
-
是的,阅读指南...启用 dataBinding 仍然缺失...
-
Adding databinding{ enabled true} 仍然给我错误,但后来我意识到 apt 应该是 apt{} ,这样我就解决了问题,这是正确的吗?虽然我现在可以导入 *.BR 谢谢你的时间 :)
