How to get index value from numberpicker in android

Question

NumberPicker np;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);             

            np = (NumberPicker)findViewById(R.id.np1);

            String[] values = {"one","two","three", "four","five","six","seven","eight"};       
            np.setMaxValue(values.length-1);
            np.setMinValue(0);
            np.setDisplayedValues(values);       
            np.setWrapSelectorWheel(false);
}

Above is a snippet of my code. So I am trying to get the index value of number picker that is selected. How do I write it? I already have something like this:

int pushupReps = Integer.parseInt(push_ups.getText().toString());

but it does not seem to be working and I have this in the OnCreate() method:

push_ups = (EditText)findViewById(R.id.pushups);

This is my main xml used:
