我正在尝试使用新材料,做了如下更改,这是我的荣幸:
android {
compileSdkVersion 28
defaultConfig {
applicationId "ir.ss.edu"
minSdkVersion 14
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'
implementation 'com.android.support:support-v4:28.0.0'
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 'android.arch.navigation:navigation-fragment:1.0.0'
implementation 'com.android.support:design:28.0.0'
}
然后我将主题更改为:
<style name="AppTheme" parent="Theme.MaterialComponents.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
当我将MaterialButton添加到布局并运行我的应用程序时,它用完了,并报错:Didn't find class "com.google.android.material.button.MaterialButton"
我该如何解决?

要使用malt
在${model.relation.field}
文件的com.google.android.material.button.MaterialButton
下添加
dependencies
也不要同时使用build.gradle
和implementation 'com.google.android.material:material:1.0.0'
的依赖关系
有关信息,请阅读此Migrating to AndroidX

添加此依赖项
implementation 'com.google.android.material:material:1.0.0'
希望这会有所帮助

如果您不想迁移到androidX并想继续使用设计支持库,则需要使用android.support.design.button.MaterialButton
而不是com.google.android.material.button.MaterialButton
尝试使用以下代码
<android.support.design.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="MATERIAL BUTTON"
android:textSize="18sp"
app:icon="@drawable/ic_android_white_24dp" />
