如何在 Android Studio 中添加 POI Android? [英] How to add POI Android in Android Studio?

问题描述

我想将 POI Android 添加到 Android Studio.gradle 代码是这样的:

I'd like to add POI Android in to Android Studio. The gradle code is this:

implementation "com.github.SUPERCILEX.poi-android:poi:$poiVersion"

但我只收到这条消息:

Could not get unknown property 'poiVersion' for object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

你能帮我吗?

推荐答案

打开你的项目级 build.gradle 文件.

Open your project-level build.gradle file.

添加以下代码片段:

allprojects {
    repositories {
        // ...
        maven { url 'https://jitpack.io' }
    }
}

然后，在 buildscript 中，添加一个对象 ext 如下.现在，将属性定义为 poiVersion 并为其分配值 3.17.

Then, inside buildscript, add an object ext as below. Now, define a attribute as poiVersion and assign the value 3.17 to it.

这类似于定义一个名称为poiVersion"的变量并赋值为3.17"

This is similar to defining a variable with name as "poiVersion" and assigning value as "3.17"

buildscript {
    repositories {
        ...
    }

    ext {
        poiVersion = '3.17'
    }

    dependencies {
        ...
    }
}

要访问该变量，您可以使用 ${variable_name}，就像您的情况一样，您使用了 $poiVersion

And to access that variable you can use ${variable_name} as in your case, you used $poiVersion
