You don’t need to setup onClickListeners programmatically. You can also put them in the layout XML like this:

<Button android:id="@+id/my_button"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/my_button_text"
    android:onClick="myOnClick"
/>

Then you can declare a base activity class that contains this method in it, like this:

public class BaseActivity extends Activity {
    public void myOnClick(View v)  {
        // Do whatever you want to do when the button is clicked
    }
}

Then you write all of your activity classes so that they derive from BaseActivity instead of Activity.
