How to get the selected number from NumberPicker?

Any idea?

You can get current picked number by calling getValue(), eg. if you have myPicker, you can do this:

String value = "" + myPicker.getValue();

If you want to get the value when it's selected by user, you need to implement NumberPicker.OnValueChangeListener interface:

private class MyListener implements NumberPicker.OnValueChangeListener {
    @Override
    public void onValueChange(NumberPicker picker, int oldVal, int newVal) {
        //get new value and convert it to String
        //if you want to use variable value elsewhere, declare it as a field 
        //of your main function
        String value = "" + newVal;
    }
}

Remember to set your listener, eg:

myPicker.setOnValueChangedListener(new MyListener());
