I have a button, and this button is going to get the values from EditText, then using this value to start a new Intent

protected void onCreate(Bundle savedInstanceState) 
{

    textDay = (EditText) findViewById(R.id.textDay);
    textMonth = (EditText) findViewById(R.id.textMonth);
    textYear = (EditText) findViewById(R.id.textYear);
    gen = (Button) findViewById(R.id.getGraph);

    gen.setOnClickListener(new View.OnClickListener() 
    {
        public void onClick(View v) 
        {   
            getthisIntent();
        }


    public Intent getthisIntent(Context context)
              {
                    day = textDay.getText();
                    month = textMonth.getText();
                    year = textYear.getText();

                    date = day + "/" + month + "/" + year;
                 .
                 .// Plot graph using AchartEngine, then return an Intent //
                 .
            }
    }
});

but i get the error

"The method getthisIntent(Context) in the type new View.OnClickListener(){} is not applicable for the arguments ()"

Can i get some help? or do i have another alternative solution, when i click the button, then the button pass the values to the new intent, and start it without having a new xxx.java file?

Edit
This is basically what I am doing now, i need to get the things inserted by user, and plot a graph, the only way i know how to plot graph using AchartEngine is create a new activity with define this

public Intent getthisIntent(Context context)

To be honest, i dont really know what the hell I am doing, please correct me...
