Android - 如何让MathView在Android上运行?

我对数学公式和搜索很感兴趣我偶然发现了这个MathView,它满足了我对我的应用程序的需求...但是我无法使它工作,我确实按照步骤通过Maven导入存储依赖项,我遇到与此处Getting MathView to work in Android

相同的问题

工具:

  • Android Studio 2.2

  • Windows 10 Pro x64

  • Gradle依赖项:

        dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
            exclude group: 'com.android.support', module: 'support-annotations'
        })
        compile 'com.android.support:appcompat-v7:24.2.1'
        compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha8'
        compile 'com.google.android.gms:play-services:9.6.1'
        compile 'com.android.support:support-v4:24.2.1'
        compile 'com.android.support:design:24.2.1'
        compile 'io.github.kexanie.library:MathView:0.0.6'
        testCompile 'junit:junit:4.12'
    }
    

这是我的布局:

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
                                             xmlns:app="http://schemas.android.com/apk/res-auto"
                                             xmlns:auto="http://schemas.android.com/apk/res-auto"
                                             xmlns:tools="http://schemas.android.com/tools"
                                             android:layout_width="match_parent"
                                             android:layout_height="match_parent">


    <io.github.kexanie.library.MathView
        android:id="@+id/formula_test"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        auto:text="When \\(a \\ne 0\\), there are two solutions to \\(ax^2 + bx + c = 0\\)
        and they are $$x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.$$"
        auto:engine="MathJax">

    </io.github.kexanie.library.MathView>
</android.support.constraint.ConstraintLayout>

这个问题有解决方案吗?

我也知道MathJax和KaTeX,但我找不到有关如何在Android中集成的任何相关信息

导入mathview中的模块。 打开文件 - &gt; new module-&gt; gradle,在这里你要从github文件夹导入mathview。

然后打开项目文件项目sturture =&gt;应用程序&gt;依赖项&gt;“+”&gt; mathview&gt;确定

然后在项目gradle中

classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'
classpath "com.github.dcendents:android-maven-gradle-plugin:1.3"
