How can I show Diameter Symbol in a textview? I used the diameter symbol (⌀) (Unicode character U+2300) but it does not work

Question

I have used this Unicode character U+2300. But its not reflection in Android Textview. I have used it in both xml layout and in java class.

@VladyslavMatviienko its showing same as U+2300. But it should show it as diameter symbol. — Anshul, Dec 05 '18 at 11:05

Try this.

String str = "\u2300";
textView.setText(str);

C/C++/Java source code              "\u2300"

Python source code                  u"\u2300"

In Android, you can not use this Unicode directly in your text view tag, but first you have to store the string value in your string.xml file and then use it from there

EX.

<string name="save">SAVE \u2300</string>

<TextView
     android:id="@+id/btnSave"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:text="@string/save"/>

Output :

when the `strings.xml` is saved in UTF-8 encoding, it should even work with the literal symbol; notice the tiny indicator in Android Studio; at the bottom of the editor window. — Martin Zeitler, Dec 03 '18 at 10:36
