Android 富文本支持表格,数学公式,图片,点击扩展 (原生和 WebView 两种模式)



原生调用:
1.RichHtml.init(applicationContext)


2.<com.example.tablerichtext.table.HtmlTextView
            android:id="@+id/htmlTextView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:padding="20dp"
            android:background="@color/white"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintRight_toRightOf="parent"
            app:layout_constraintTop_toTopOf="parent" />


 3.this.findViewById<HtmlTextView>(com.example.tablerichtext.R.id.htmlTextView)
 .setHtml(App.getSample(), HtmlCompat.FROM_HTML_MODE_LEGACY, null, null)   


H5 调用:
   <com.example.tablerichtext.mathweb.MathView
        android:id="@+id/math_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        >
    </com.example.tablerichtext.mathweb.MathView>

this.findViewById<MathView>(R.id.math_view)
            .setDisplayText(App.getSample())

    With billions of Android devices around the world, Android has surpassed our wildest
    expectations. Today at Google I/O, we showcased a number of ways we’re pushing
    Android forward, with the
    <a href="https://developer.android.com/preview/index.html">O Release</a>, new
    tools for developers to help create more performant apps, and an early preview of a
    project we call Android Go -- a new experience that we’re building for entry-level
