How do I detect touch input on the Android

I did it like this:

public class ActivityWhatever extends Activity implements OnTouchListener
{

    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.yourlayout);

        //the whole screen becomes sensitive to touch
        mLinearLayoutMain = (LinearLayout) findViewById(R.id.layout_main);
        mLinearLayoutMain.setOnTouchListener(this);
    }

    public boolean onTouch(View v, MotionEvent event)

        // TODO put code in here

        return false;//false indicates the event is not consumed
    }
}

in the xml of your view, specify:
