You need to instantiate a new NumberPicker:

NumberPicker np=(NumberPicker) findViewById(R.id.numberPicker);

Of course, you need to instantiate it the the XML layout file and name it "numberPicker" (or whatever you like but remember to replace the name in here: R.id.numberPicker)

Then, create the array of Strings that will be the choices of your NumberPicker. For example:

String[] values=new String[3];
values[0]="mike";
values[1]="sue";
values[2]="harry";

Then set set the value array to it, the Max and Min values for the picker (this is what will be returned for each value. The code provided below works for any values array like the one above)

np.setMaxValue(values.length-1);
np.setMinValue(0);
np.setDisplayedValues(values);

All the code was taken from this guide where you can also find more information, examples and styling solutions.
