Answer 1

您必须使用相同的版本，因此请将gradle文件更改为：

defaultConfig {


      applicationId "com.example.joshua.exigent"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    }

    dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.4.0' 
    compile 'com.android.support:design:23.4.0' 
    compile 'com.google.firebase:firebase-database:10.0.0'

    compile 'com.firebaseui:firebase-ui-database:0.6.2'

    compile 'com.android.support:recyclerview-v7::23.4.0'

    compile 'com.android.support:cardview-v7:23.4.0'
    }

Answer 2

您需要使所有支持库版本相同，即 23.4.0

    compile 'com.google.firebase:firebase-database:10.0.0'
    compile 'com.firebaseui:firebase-ui-database:0.6.2'

    compile 'com.android.support:design:23.4.0'
    compile 'com.android.support:appcompat-v7:23.4.0'
    compile 'com.android.support:recyclerview-v7:23.4.0'
    compile 'com.android.support:cardview-v7:23.4.0'

当我试图包括回收者和卡片视图dependecies时，它显示这个支持libarary不应该是不同的版本
