The problem is I want to show m2 in Number Picker like 50 m2 100 m2 but Number Picker only show String and I can't. Please help me fix that. Tks everyone.


Solution

  • Using Unicode Character makes it very easy :

    First create an array with your values(this will go to the number picker)

    String mValues[] = { "100 " + "\u33A1", "200 " + "\u33A1" };
    

    Now use this method to create number picker with custom values:

     private void setNubmerPicker(NumberPicker nubmerPicker,String [] numbers ){
        nubmerPicker.setMaxValue(numbers.length-1);
        nubmerPicker.setMinValue(0);
        nubmerPicker.setWrapSelectorWheel(true);
        nubmerPicker.setDisplayedValues(numbers);
    }
    

    And for the final step call this method:

      setNubmerPicker(yourNumberPicker,mValues);
