android - How to reduce the font size in NumberPicker -

all, i'm customizing city picker, uses 3 numberpicker inside,like this:

its chinese province-city-area picker.

the code:

string[] areas = get_from_somewhere(); areapicker.setdisplayedvalues(areas);

i want cut down font size,any advice?

solution: refer this

you can extend default numberpicker in custom class customnumberpicker this:

public class customnumberpicker extends numberpicker { public numberpicker(context context, attributeset attrs) { super(context, attrs); } @override public void addview(view child) { super.addview(child); if(child instanceof edittext) { ((edittext) child).settextsize(25); } } }

now replace current numberpicker in xml customnumberpicker:

<com.pkg.name.customnumberpicker android:id="@+id/number_picker" android:layout_width="match_parent" android:layout_height="wrap_content" />

android numberpicker
