How do I insert special characters as text in XML editor for Android?



You are writing an app that involves using some mathematical symbols. I'm doing this in the visual XML editor.
Is there any way I can get, say, an integral symbol, or a "less than or equal to" symbol?


Answer is  - Yes.


String htmlStringWithMathSymbols = "≤  ≥";
textView.setText(
Html.fromHtml(htmlStringWithMathSymbols)); 
OR
<string name="item_unknown">\u003c Item Unknown \u003e</string> 




Some other example –

String htmlStringWithMathSymbols = "&amp;#8722;   &amp;#43;   &amp;#177;   &amp;#215;   &amp;#247;   &amp;#37;  &amp;#137;   &amp;#61;   &amp;#8800;   &amp;#8776;   &amp;#8801;   &amp;#60;   &amp;#62;   &amp;#8804;   &amp;#8805;   &amp;#8734;   &amp;#8539;   &amp;#188;   &amp;#8540;   &amp;#189;   &amp;#8541;   &amp;#190;   &amp;#8542;   &amp;#8747;   &amp;#8706;   &amp;#8710;   &amp;#8719;   &amp;#8721;   &amp;#8730;   &amp;#8735;   &amp;#8745;   &amp;#8729;   &amp;#131;   &amp;#8260;   ";
  
textView.setText(Html.fromHtml(htmlStringWithMathSymbols));







You can display your math symbol in textView

Example –

Use &lt; for <, &gt; for > and &amp; for &. 
<   less than       &lt;     

>   greater than    &gt;     

&   ampersand       &amp;    

¢   cent            &cent;   

£   pound           &pound;  

¥   yen             &yen;    

€   euro            &euro;
