Numberpicker Textcolour

I have a ListView containing a TextView and a NumberPicker for each row. Whenever I start up the activity, the numbers of the NumberPicker are white (the same color as the backgrou

Solution 1:

I know the question is old. I founded the answer here: Change the text color of NumberPicker

Copy:

This code should solve your problem. The problem you are experiencing is because during the construction of NumberPicker it captures the EditText textColor and assigns to to a paint so it can draw the numbers above and below the edit text with the same color.

import java.lang.reflect.Field;

publicstaticbooleansetNumberPickerTextColor(NumberPicker numberPicker, int color)
{
    finalintcount= numberPicker.getChildCount();
    for(inti=0; i < count; i++){
        Viewchild= numberPicker.getChildAt(i);
        if(child instanceof EditText){
            try{
                FieldselectorWheelPaintField= numberPicker.getClass()
                    .getDeclaredField("mSelectorWheelPaint");
                selectorWheelPaintField.setAccessible(true);
                ((Paint)selectorWheelPaintField.get(numberPicker)).setColor(color);
                ((EditText)child).setTextColor(color);
                numberPicker.invalidate();
                returntrue;
            }
            catch(NoSuchFieldException e){
                Log.w("setNumberPickerTextColor", e);
            }
            catch(IllegalAccessException e){
                Log.w("setNumberPickerTextColor", e);
            }
            catch(IllegalArgumentException e){
                Log.w("setNumberPickerTextColor", e);
            }
        }
    }
    returnfalse;
}

Solution 2:

Are you using a Formatter? I had to use setDisplayedValues to fix the problem. I assume you have already solved this problem, but I'm posting this anyway, I for one was desperate looking for an answer, solved it by accident.

NumberPickernumberPicker=newNumberPicker(getActivity());
    numberPicker.setMinValue(0);
    numberPicker.setMaxValue(5);     
    String[] periodicityValues = {"Semanal", "Mensal", "Bimestral", "Trimestral", "Semestral", "Anual"};
    numberPicker.setDisplayedValues(periodicityValues);
