添加compile RecyclerView后Gradle清单合并失败

Question

在能够导入RecyclerView后弹出此错误消息。我找不到源头，也找不到解决方法。错误消息似乎也很难理解。

错误：任务“:app:ProcessDebugManifest”执行失败。清单合并失败：来自[com.android.support:AppCompat-V7:25.3.1]androidmanifest.xml:27:9-31的属性元数据#android.support.version@value value=(25.3.1)也出现在[com.android.support:RecyclerView-V7:26.0.0-alpha1]androidmanifest.xml:24:9-38 value=(26.0.0-alpha1)中。建议：将'tools:replace=“android:value”‘添加到AndroidManifest.xml:25:5-27:34处的元素以覆盖。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.me.listviewprojektfuerapp">

    <application

        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".ui.ListActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Build.Gradle（模块：App）：

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.3"
    defaultConfig {
        applicationId "com.example.me.listviewprojektfuerapp"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:recyclerview-v7:26.0.0-alpha1'
}

Answer 1

您正在使用com.android.support:appcompat-v7:25.3.1和com.android.support:recyclerview-v7:26.0.0-alpha1,recyclerview-v7:26.0.0-alpha1是appcompact库的一部分,因此会发生冲突,而且建议使用相同的库版本
