它向我显示此错误：

Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute meta-data#android.support.VERSION@value 
value=(26.0.0-alpha1) from [com.android.support:design:26.0.0-alpha1] 
AndroidManifest.xml:27:9-38
is also present at [com.android.support:cardview-v7:25.3.1] 
AndroidManifest.xml:24:9-31 value=(25.3.1).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at 
AndroidManifest.xml:25:5-27:41 to override.

Answer 1

更改您的

compile 'com.android.support:cardview-v7:25.3.1'

自

compile 'com.android.support:cardview-v7:26.+'

因为所有支持库都应该是相同的版本。

Answer 2

使用完全相同的依赖项版本而不是26.+

compile已弃用

也使用implementation代替compile

试试这个

implementation 'com.android.support:appcompat-v7:26.1.0'
implementation 'com.android.support:design:26.1.0'
implementation 'com.android.support:cardview-v7:26.1.0'
