我收到此错误:
无法解析符号'@ style / Widget.MaterialComponents.TextInputLayout.OutlineBox'
我在XML中将此行添加到TextInputLayout后出现此错误:
style="@style/Widget.MaterialComponents.TextInputLayout.OutlineBox"
这是我的完整XML代码(删除了不相关的约束/边距):
<android.support.design.widget.TextInputLayout
android:id="@+id/textInputLayout2"
style="@style/Widget.MaterialComponents.TextInputLayout.OutlineBox"
android:layout_width="match_parent"
android:layout_height="0dp"
app:counterEnabled="true"
app:counterMaxLength="300">
<android.support.design.widget.TextInputEditText
android:id="@+id/cheese_description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="start"
android:hint="@string/cheese_description" />
</android.support.design.widget.TextInputLayout>
这是我的app build.gradle:
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
defaultConfig {
applicationId "app.cheese.cheese.some.sample_cheese"
minSdkVersion 19
targetSdkVersion 27
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
buildToolsVersion '27.0.3'
}
dependencies {

implementation 'com.android.support.constraint:constraint-layout:1.0.2'

implementation 'com.android.support:recyclerview-v7:27.0.2'
implementation 'com.firebaseui:firebase-ui-database:3.2.1'
}
apply plugin: 'com.google.gms.google-services'
这是我的另一个build.gradle:
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.1'
classpath 'com.google.gms:google-services:3.1.1'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
maven {
url "https://maven.google.com"
}
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
我试过了:
我采用了导致错误from the material.io components here的XML代码行。有谁知道我做错了什么?
谢谢 :)
Material Components尚未在com.android.support:design
依赖下发布新版本(或者通过你的build.gradle
文件中可以包含的任何其他官方依赖),所以你在27.0.2
中看到的不包含任何最近的变化 - 例如支持为Widget.MaterialComponents.TextInputLayout.OutlineBox
。
如果要访问最新更改,则必须将所需的材料组件库部分直接复制到项目中。
这两个答案都是正确的,但我发现这个链接上的代码给出了一个错误https://codelabs.developers.google.com/codelabs/mdc-111-kotlin/#2上的OutlineBox错误拼写正确的代码是
style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
如果您使用新包装作为支持库,您应该使用:
com.google.android.material:material:1.0.0-beta01
依赖于此
添加以下依赖解决了我的问题
implementation 'com.android.support:design:28.0.0'
我的完全依赖是
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
implementation 'com.android.support:design:28.0.0'
}
这种风格来自设计支持库v28 alpha版本的部分,直到android p发布它才发布。要使用此更改compileSdkVersion到'android-P'并使用此依赖项来使用它
implementation 'com.android.support:design:28.0.0-alpha1'
我得到了相同的问题,我在dependencies
下面解决了
使用下面的dependencies
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
implementation 'com.android.support:design:28.0.0-alpha3
