Android Studio androidx.coordinatorlayout错误以及如何设置3Dot菜单？
问题描述 投票：5回答：2
我有以下问题。我的android工作室显示错误，这是在标题Screenshot写的alredy。我试图在右上角实现漂亮的3点菜单。如果有人能告诉我这是什么问题，那将是非常好的......
尝试gradle时得到的错误是：
C:\Users\User\AndroidStudioProjects\BluetoothCar\app\src\main\java\com\car\bluetooth\bluetoothcar\MainActivity.java:11: error: package android.support.design.widget does not exist

import android.support.v7.widget.Toolbar;
我已经尝试导入v7.widget.toolbar，但它标记了v7红色并说无法解析符号。

这将解决您对coordinatorLayout的第一个问题
implementation 'com.android.support:design:27.1.1'
将此依赖项添加到app.gradle文件中
这也将解决您的AppBarLayout问题
由于错误清楚地表明您没有设计包，
C:\Users\User\AndroidStudioProjects\BluetoothCar\app\src\main\java\com\car\bluetooth\bluetoothcar\MainActivity.java:11: error: **package android.support.design.widget does not exist**
import android.support.design.widget.AppBarLayout;
C:\Users\User\AndroidStudioProjects\BluetoothCar\app\src\main\java\com\car\bluetooth\bluetoothcar\MainActivity.java:12: error: **package android.support.v7.widget does not exist**
import android.support.v7.widget.Toolbar;

同
dependencies {
implementation fileTree(dir: 'libs', include: ['*.jar'])
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'android.arch.navigation:navigation-fragment:1.0.0-alpha05'
implementation 'android.arch.navigation:navigation-ui:1.0.0-alpha05'
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'
}
有一个appcompat的副本，其他依赖项对版本看起来不太好。

如何添加两个缺少的依赖项？
implementation 'com.android.support:design:27.1.1'
implementation "com.android.support:appcompat-v7:27.1.1"
