将 LibGDX 项目放入项目？

Question

我知道这个问题已经被问过很多次了，但我仍然找不到正确的步骤。我正在使用 Android Studio。我如何实际将 LibGDX 项目放入 Android App 项目（而不是将 Android App 项目放入 LibGDX 项目）？这就是它应该如何工作的。当我按下 Android 应用程序中的按钮时，我可以通过设置游戏屏幕来启动我的游戏。玩完游戏后，我可以再次回到 Android 应用程序。我需要配置 Gradle 文件吗？如果是这种情况，我该如何更改它？

这是我在将libGDX模块导入到AndroidApp项目时遇到的问题

Could not find method android() for arguments [build_f3607d3g9oo7ee40quzhms085$_run_closure1@18e45678] on project ':android' of type org.gradle.api.Project.

是否需要进行额外配置？

这是我的 Android 构建 Gradle 文件。

android {
    buildToolsVersion "29.0.2"
    compileSdkVersion 29
    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
            jniLibs.srcDirs = ['libs']
        }

    }

        exclude 'META-INF/robovm/ios/robovm.xml'
    }

        }
    }

Answer 1

在您的主应用程序中 build.gradle

复制行apply plugin: 'com.android.application'

移入导入的gdx项目build.gralde

并在 android 块之前粘贴 apply plugin: 'com.android.application'

在您的 gdx 项目中向下滚动 build.gradle 并注释掉 eclipse 和 idea 块也..

进入核心build.gradle并注释掉eclipse块..

同步和项目应该成功构建
