    Lightbulb Textview font size

    hi gurus, just want to seek info.

    In textview is it better to set the size in sp units or what is the best option?

    if set to sp font will auto adjust to user settings or to screen sizes?

    Thanks for any input.

    HI

    sp is better option . it will adjust according to system font settings. but you have to do generic layout for fitting the text view in all kind of Big ,small or normal fonts.

    You shouldn't have to set the text size manually. Use in XML android:textAppearance="?android:attr/textAppearanceMedium" for average textsize.
    Why? Because this way the text scales accordingly on different mobile devices.
    If you set 12Sp text will look ok on a xhdpi screen, but really small on xxxhdpi...

    Setting the font size to sp is a better option than using dp. However, if you want the fonts to self-adjust themselves according to screen size, then you must use the code android:textAppearance="?android:attr/textAppearanceLarge" or android:textAppearance="?android:attr/textAppearanceMedium" for large or medium fonts. Using this code will make the fonts dynamic so that they can adjust as per the screen sizes.

    Text appearance Medium, large or small are also set on the res/values/themes.xml and is pre-defined by "sp" size also.

    <style name="TextAppearance.Medium">
    <item name="android:textSize">18sp</item>
    </style>
