MathView

MathView is a library to render Math equations in Android. It uses jqMath to render math equations.

Setup

Add it in your root build.gradle at the end of repositories:

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

Add implementation 'com.github.frhnfrq:MathView:1.2' into dependencies section of your module build.gradle file. For example:

dependencies {
    implementation 'com.github.frhnfrq:MathView:1.2'
}

Usage

Add `MathView` in your layout

<com.zanvent.mathview.MathView
    android:id="@+id/mathview"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

Get an instance of it in your code

MathView mathview = findViewById(R.id.mathview);
mathview.setText("If $ax^2+bx+c=0$ with $a≠0$, then: $$x={-b±√{b^2-4ac}}/{2a}$$");
mathview.setPixelScaleType(Scale.SCALE_DP);
mathview.setTextSize(16);
mathview.setTextColor("#111111");

How to

To learn how to write math equations in it, please have a look at jqMath.

Advantages

Faster than MathJax.
Change text size and color easily.
Supports HTML outside of the equation. Example

mathview.setText("This is a <b>straight</b> line, $\ax + \by = \c$");

Disadvantages

Special symbols are typed manually. Example: √ ∑ ∫ ← → + >
Some parts of the MathML standard are not yet implemented in jqMath, such as elementary school mathematics (e.g. “long division”), and “Content MathML.”
