[英]Synthetic of kotlin extensions does not work when I import Android-ktx in gradle
I'm trying to test some android jetpack features in my project, I already have the navigation working. 我正在尝试在我的项目中测试一些android jetpack功能,我已经在使用导航功能。 When I tried to import android-ktx and migrate my dependencies to androidx I managed to synchronize the gradle successfully, but I lost access to my button through synthetic.
当我尝试导入android-ktx并将依赖项迁移到androidx时,我成功地成功同步了gradle,但是我无法通过合成访问按钮。
Anyone have any idea what it can be? 有人知道它可以是什么吗?
My Gradle: 我的摇篮:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.qmakercorp.qmaker"
minSdkVersion 22
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.support.test.runner.AndroidJUnitRunner"
}
androidExtensions {
experimental = true
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.2.71"
implementation 'androidx.appcompat:appcompat:1.0.0'

testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test:runner:1.1.0-beta01'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.0-beta01'

androidTestImplementation 'androidx.test:rules:1.1.0-beta01'
implementation 'androidx.core:core-ktx:1.0.0'
My Fragment: 我的片段:
In your app build.gradle
file you imported androidx.legacy:legacy-support-v4:1.0.0
and clicked Sync Now
. 在您的应用程序
build.gradle
文件中,您导入了androidx.legacy:legacy-support-v4:1.0.0
并点击Sync Now
。 After that you had error saying Manifest merger failed : Attribute bla bla ...
and commented com.android.support:support-v4:28.0.0
but there wasn't shown Sync Now
and you didn't sync your project with gradle files. 之后,出现错误,提示
Manifest merger failed : Attribute bla bla ...
并评论了com.android.support:support-v4:28.0.0
但未显示“ Sync Now
,也没有将您的项目与gradle文件同步。 That's way you still able to use android.support.v4.app.Fragment
from LoginFragment
. 这样,您仍然可以使用
LoginFragment
android.support.v4.app.Fragment
。 Suggestion: click Sync Project with Gradle Files
button and replace import android.support.v4.app.Fragment
with import androidx.fragment.app.Fragment
. 建议:单击
Sync Project with Gradle Files
按钮,然后将import android.support.v4.app.Fragment
替换为import androidx.fragment.app.Fragment
。
