Answer 1

Use onCreate method to set the UI and to get the Widget from UI.

protected void onCreate(Bundle savedValues) {
    // Here set the UI and get the widgets
    //set the Listeners on the widgets you are getting at the above line
}

And you can define a clickListener for the widgets and use it in onCreate method

OnClickListener someListener = new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        Toast.makeText(v.getContext(), "widget pressed ", Toast.LENGTH_SHORT).show();

    }
};

and you can set the above clickListener to a widget which you have created in onCreate method
