Regarding Dynamic Generation of Math and Science Formulas in Textview

Question

I have a problem with reading and displaying mathematics and science formula. They're not showing up like in the images given below. I'm displaying it in a TextView, and I used setTypeface to set the font as the "Gujarati" font.

Thank you in advance.

I want to display mathematics formula like:

enter image description here

... and also display science equations like:

enter image description here

And, how to read Excel sheet and store in SQLite database in Android? I don't use .csv because I store Gujarati data in Excel.

You can display mathematical function using HTML code in string.xml file in value folder. Like example:

<string name="superscript"><html><i>a</i><sup>2</sup>+<i>y</i><sup>2</sup></html></string>
<string name="subscript"><html>f(x)<sub>1+x</sub></html></string>

and write in your xml file TextView:

 <TextView
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="@string/superscript" />

   <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/subscript" />

for mathematical symbols and character, you can check this link:

You can use ImageView and show the images of these expressions. This would be quite easy.
